eBike technology from Bosch - hands-on

View fullsize

A couple of weeks ago, Bosch eBike Systems brought an eBike out to me so I could try it out. What's an eBike, you ask? In technical terms, an eBike is a bicycle that has been augmented with an electrical assist that provides supplemental power while you pedal. In practical terms, it is an impressive tool to help you simplify your commuting or road cycling jaunts.

Bosch doesn't make the bikes - they make the "mid-drive" systems that are built into the bikes, so you can find different types, sizes and styles of bikes to fit your needs and preferences. You can find out more and locate a dealer near you at the Bosch eBike site. [Note: I receive no compensation or other consideration for this - just a free ride on an eBike].

Mount up...

I was riding a Haibike XDuro Trekking RX bike with Bosch Mid-Drive technology (provided by Cynergy E-Bikes, a local Portland company), and it was my first time riding an eBike. 

The bike looks a lot like a typical hybrid bike (built for road cycling, and off-road friendly), and I immediately noticed the weight - it was noticeably heavier than the bike I typically ride. That extra weight is because it has batteries on board, and the frame has been reinforced to handle the forces of the electrical assistance mechanism - the Bosch system is built in during the design of the bike, not bolted on afterward, so it is quite sturdy.  

Once on the bike, it rode and handled very well - it felt like a normal commuting bike, and it took no time at all to get acclimated (and it didn't feel very heavy from a rider's perspective). 

Becoming Superhuman

I rode for a couple of miles near downtown Portland, in a big loop along the Willamette River promenade, which gave me a chance to experiment on flat, straight sections as well as some good inclines, congested areas, and curves. The bike was a lot of fun to ride and I found myself thinking about what it would be like to own.

The real fun started when I turned on the eDrive -- I felt superhuman! It is hard to describe the feeling you get when you turn on the eDrive and the bike begins to surge forward, accelerate, and climb up challenging hills under the assistance of the eDrive.

The way Bosch's eDrive system works is by multiplying your power so every pound of pressure you exert on the pedals is amplified when it reaches the wheels. There are 5 modes:

• Off:     no assistance from drive unit
• Eco:    50% assistance from drive unit
• Tour:    120% assistance from drive unit
• Sport:    190% assistance from drive unit
• Turbo:    275% assistance from drive unit

You can change modes on the fly, smoothly and without interrupting the ride. That means you can spend most of your time in Eco, but kick things into Turbo for a killer hill or to make up some time on the road when you're in a hurry.

When choosing modes, keep in mind that the more assistance you get from the eDrive, the faster you use up the battery's charge. For example, depending on conditions, the range in Turbo mode (highest assistance) is 20-40 miles. In Eco mode (least assistance) the range is 50-100 miles. The on-board control panel tells you how you're doing and estimates remaining range based on how you're using the bike.

These bikes do need to be recharged, as they don't recharge while you are riding. That said, they last quite a while - you should only have to charge the bike once or twice a week if you use it for commuting, and the recharge time is about 3 hours (you just plug the bike's charger into a normal household outlet). If you run out of power on the road, you won't be stranded - you can simply pedal it as you would a normal bike (though the additional weight may make pedaling a bit more difficult on hills without the power assist).

Who are eBikes suited for?

While anyone would enjoy this bike, it is ideally suited for commuters, as well as people who are less physically adept but want to ride in hilly terrain (or more easily keep up with more accomplished riders). Bosch says these systems are very popular with the 50 years and up crowd, since they like the physical assistance the bikes provide and typically have more disposable income to justify the extra cost (eBikes typically cost about $1500-2000 more than comparable, conventional bicycles).

Commuters will likely appreciate these bikes most - imagine riding 10 miles to work on an eBike and arriving at work without feeling like you need to take a shower; that is possible with the assistance of the eBike power drive. If you get the chance, stop by a local bike dealer who stocks eBikes, and give it a try - I think you'll be impressed.

Is Your Apple Watch's Crown Dial Getting Sticky? Don't Sweat It

I recently got an Apple Watch, and the other day I noticed the crown dial (aka the "little spinny knob thingy") was suddenly hard to rotate, and not very responsive to clicks. 

After a little thinking and experimenting, I remember that I'd been using the Watch to record workouts and it's been particularly hot in Portland lately. It seems that the minerals in my sweat were accumulating under the crown knob and making interfering with its proper operation.

Wash away your troubles

If this happens to you, the fix is easy. Simply rinse off the watch in warm (not hot) water with mild soap. Rinse the watch well and, while rinsing it, rotate the knob a bit to get the mineral crystals worked out of the mechanism.

I've done this a couple of times now, and it fixes the problem easily - in fact, since I have a sport band (the rubbery one) I think I'll just wear it in the shower to keep it clean. The watch is water-resistant and this kind of exposure should not be a problem. According to Apple:

Apple Watch is splash and water resistant but not waterproof. You can, for example, wear and use Apple Watch during exercise, in the rain, and while washing your hands, but submerging Apple Watch is not recommended. Apple Watch has a water resistance rating of IPX7 under IEC standard 60529. The leather bands are not water resistant.

By the way, there are also articles from other sources discussing tests that indicate that the Apple Watch is even more water-resistant than Apple's claims indicate.  

Updated: How to lose 50 pounds in 6 months

Originally published June 17, 2014.

[February 16, 2015: Updated information about my fitness tracking bands]

As I mentioned in my previous post, I've lost over 50 pounds since last July and have learned some things along the way.  I thought I'd share some of my experience here, in the hopes that others might benefit.  By the way - I know this ended up being a bit long, but hopefully it's broken up enough to make it usable.

10 months into the process (I started trying to lose weight August 1, 2013), and I'm doing a good job of maintaining and sticking with my program  I was just updating my photo with a new one just taken for work, and I thought it was worth updating my original post from March with a bit of data.  My daughter showed me the Google search that came up with the freeze frame from a YouTube video posted last June - that's the picture on the left.

First, I started this journey due to a "wake up call" from my Doctor at my last physical.  Getting older, plus a lot of travel, plus some bad habits (no exercise, poor discipline when it comes to eating, etc.) had all stacked up and the odds were no longer in my favor.  Here is what I did.

Goals

Working with my doctor, I set a target weight based on my height, age, etc.  To get to my target, the basic math never changes:  you need to consume fewer calories than you burn.  I didn't want to try some "quick fix" fad diet, so I tried to approach this in a way that I could maintain over the long haul.

With the weight target in hand, I determined the number of calories needed to maintain that target weight, using an online calorie calculator.

From there, I set several goals to support my journey:

• exercise at least 3 times per week.
• consume calories at or below my daily target to maintain my goal weight
• lose at least a pound a week until I reach "steady state" at this new calorie level
• reduce my sodium intake (blood pressure was one of the concerns that came up in my physical exam)

Instrumentation

As you may gather from this blog, I'm a fan of gadgets. So, naturally, I looked for gadgets that would help me track my progress.  I used several tools for this - not required, but they help:

• A fitness tracking band to track my exercise. [Update February 16, 2015: Fitbit has come out with updated trackers since my original pos, and I have tried all 3 of the new ones. Fitbit is by far my favorited fitness band provider, and my recommended choice right now. I have also used a Jawbone Up24 in the past and, while I like it, I prefer having a band with a digital display.  For the record, the brand of fitness band you choose isn't critical - pick one you like that has the features you need - for less stress, look for good battery life. Here are my three recommended bands at this time:
  • Fitbit Charge: This tracker is the most similar to the Fitbit Force I knew and loved. It tracks steps you take, flights of stairs you've climbed, tracks your sleep, can function as a watch, can show notifications from your smartphone, and has a vibrating alarm. Highly recommended for basic fitness tracking. You'll get 7-10 days of battery life from this (closer to 10 in my experience). The only issue I've had with this is that the clasp used can sometimes get pulled open on coats, or when reaching into bags.
  • Fitbit Charge HR: This is almost the same as the Charge, above, but adds a heart rate tracker that can track your heart rate 24/7. This one adds a more secure buckle in place of the Charge's clasp. Battery life is more like 5-7 days. This is my new favorite, since it adds the heartrate functionality but doesn't feel bulky.
  • Fitbit Surge: This is more like a traditional sports watch, with a much larger (and more useful) display. It has the same functions as the other two Fitbits above, but adds a run tracker with GPS that can record a run (time, distance, and route) even without your smartphone. It also has "record this exercise" functions for Hiking, Weights, Yoga, Elliptical, Spinning, and general Workout tracking. Battery life is about 5 days without using the GPS function - you'll need to charge much more frequently if you use the GPS function to track a run (though that feature is highly accurate, and syncs your heart rate with your location, elevation, etc.) This device is a close second for me, and would be first if the battery life were a bit longer and it were a little slimmer. End of update]
• A Withings WiFi-enabled digital scale with body composition sensors.  This scale is accurate, automatically updates my phone (the Withings App) with my weight, body fat percentage, pulse, etc. so I can track progress over time.
• A Withings blood pressure cuff that connects to my iPhone and records blood pressure readings.  This takes your blood pressure readings automatically, and syncs them with the same Withings App that the scale uses.  [Update: I have since upgraded to the wireless version of the WIthings blood pressure cuff - no difference in accuracy, but I love the convenience of Bluetooth.]
• MyFitnessPal which is a great app to track what you eat, as well as to track exercise.  This also syncs automatically with my Fitbit and my WIthings scale, which is pretty cool - you can optionally allow it to subtract the calories you burn, for example, so you can eat more if you exercise more.
• A digital food scale - this is crucial for recording your portion sizes for accuracy
• I later added a Polar Heart Rate Sensor once I switched form walking to running.  I use their app (Polar Beat) to track distance, pace, calories burned, etc.  I like this app as it gives me audio feedback as run, such as my distance (it uses the phone GPS to track distance), pace, average hear rate, and it tracks distance and calorie records.  You can even "replay" your run on a map view, showing your pace and heart rate at different points along the run.

Of course, you don't need all of these gadgets, but I find they helped keep me motivated.  I believe the "must have" items are MyFitnessPal, the food scale, and some kind of digital scale to weigh yourself.

Habits

Since I'd developed bad habits in the past, I needed to develop new habits to be successful.  The ones I targeted were:

• walk at least 10,000 steps per day (tracked by the Fitbit) [Update: My target is now 12,000 steps per day]
• diligently track my food consumption with MyFitnessPal (there is a web site as well as a collection of mobile apps for most platforms)
• exercise deliberately (i.e. beyond just "incidental" walking during the day) including while traveling
• once I added running to my routine (more on that below) I set a goal to run at least 3 days per week for at least 30 minutes each session

Diet

At home, I began weighing my portions so I could log them.  MyFitnessPal makes that easier because of its huge database of foods, and its ability (if you're using the smartphone app) to scan a barcode and auto-populate the nutrition and portion information.  After a while, this habit of weighing your portions also helps you guesstimate portions in restaurants to keep you from going way overboard.

I found that measuring and logging my food had another effect: I started thinking about the tradeoffs I wanted to make.  For example, when I realized how many calories I was consuming with my nightly glasses of wine, I knew I either had to "reserve" space in my calorie budget to be able to have my wine or just skip it that day.  The same thing for desserts - I could have that piece of cake, but I needed to not eat something else to make the budget work.  That took a while to get used to, but it's been a good change.

One piece of advice that has really helped:  my nutritionist told me that if I "blew" a day by eating too much, not to try to make up for it by under-eating the next day.  Instead, he advised me to start fresh the next day and stick to my calorie target.  He explained that we're dealing with averages and that if I'm able to stay at or below my target most 90% of the time, I'll be able to sustain a good level of fitness.

Exercise

Easy does it

From an exercise perspective, I started out with walking.  I'd walk for an hour a day after dinner at a pretty good pace - about 4 miles per hour.  Over time, I began to mix in more hills and occasionally walk for two hours when I could afford the time.  To make the time go by more quickly, I listened to podcasts and audiobooks (I listened to Atlas Shrugged during my evening walks, for example - it is NOT a short book).  I also did a couple of weight workouts per week at my local gym - nothing too extreme, but enough to build strength and balance out the lower-body work from the walks.

Pick up the pace

After a few months, a few things changed - first, the walks got to be a bit monotonous; second, the weather got to be unfriendly; and third my travel picked up which made it harder to find time for the walks.  I started looking for more time-efficient ways to get my workout in, so I began to do more intense (faster) walks in the gym on the elliptical trainers because they worked my arms & legs at the same time.  This worked well, but also got to be a bit monotonous and some hotel gyms didn't have the elliptical trainers. 

Full speed ahead

For my next phase of changes (roughly a month ago), I decided to add running into the mix.  At first, it was challenging since there is a big difference between walking fast and running (in endurance, impact on my knees & hips, etc.)  However, with all the walking I'd done, it wasn't as bad as I feared.  I did some running outside when the weather was good enough, or in the gym on a treadmill when it wasn't - and pretty much every hotel gym has a treadmill.  I've been gradually increasing my distances and my pace to keep things challenging, and the addition of a heart rate strap has been a big help there.

Planning

Along the way, I found that planning ahead was crucial to my success.  Rather than eating what happened to be available, I began planning ahead to try to aid in making good choices.  The same was true of exercise - if I didn't plan ahead, it didn't happen.  For example:

Food Planning

• General
  • When I'm not traveling, I tend to plan my meals more so I have more control over what I eat rather than being tempted to snack on the first thing at hand or eat something just because "it's there" - this means having a plan before you go shopping, and knowing what your options are when it comes time to prepare meals.
  • When I don't have a lunch appointment, I make and bring my own lunch - again, planning ahead so I don't make less healthy or "off plan" choices
• Travel
  • I now travel with a stash of Kind bars in my bag (good ingredients, low sodium, and a balanced nutritional profile) in case I find that I need a quick snack on the run.  Starbucks used to carry these, but they have since replaced them with a different brand that also has good nutritional composition, albeit with fewer flavor choices (I like the Almond Cocoa flavor a lot).
  • Grab a durable fruit (like an apple or an orang) and tuck it in your carry-on bag so you have a ready snack.  
    • Carrying napkins and some empty plastic bags can help for cleanup and disposal of the core, peel, seeds, etc
• Restaurants
  • I do some quick research ahead of time to find out what's on the menu, narrow down my choices ahead of time, and and to determine low-sodium options
    • MyFitnessPal is a big help here - it has calorie nutritional information from a lot of restaurants so you can compare choices
    • I've also noticed that more restaurants provide nutritional information on their menus or web sites, and some even include "meal builder" capabilities so you can customize your choice and see the impact of the changes in real-time

Exercise Planning

• Schedule workouts, walks, etc. and keep the appointments (it helps to pretend you are meeting with a customer or something so you don't break the appointment)
• Leave (or plan) time in your travel for workouts
  • for example, I sometimes take advantage of "time zone math" to get a workout in late at night on the east coast, or early in the morning on the west coast
• Find a good place to run or walk near your office and combine a short walk with a quick lunch a couple of times a week
• Choose "exercise friendly" hotels.  Hotels have gotten a lot better at telling you what their fitness amenities are on their web sites, which makes this easier all the time.  By the way, through this process I have grown even more for fond of Starwood hotels:
  • Some Starwood hotels (Westin, Sheraton) allow you to rent workout gear for $5 a day - including shoes.  That is hugely convenient when you don't have a lot of room in your suitcase.  Other Starwoods (Le Meridién) will even wash your workout clothes for you overnight, free of charge.
  • Starwood hotels also offer running maps of the local area with short and long running routes.
  • Their Westin brands have begun offering "Westin Workout" rooms, which allow you to reserve a room (in some locations, not all) with a treadmill or an exercise bike right in your room.  I posted a video tour of one of those rooms last year.
  • Most Starwoods offer free apples as a good, healthy snack either at the front desk, in the fitness center, or both.

Results, not just activity

I'm happy to say that this approach (while it may seem overwhelming when you read through it) has worked for me, and hasn't been as difficult as I'd feared.  I have made consistent progress:

Progress graph from the Withings app, showing measurements from my WiFi scale.

• I've lost over 50 pounds
• I've lowered my blood pressure, blood sugar, and cholesterol levels dramatically
• I've trimmed down (warning, if this goes well, you'll spend quite a bit for a new wardrobe during the first 6 months)
• I have much better energy and overall fitness

I'm still making progress, and now that I've added more strength exercise into my routine, my weight is holding more steady.  I am now in a "maintain" mode, which I feel I can sustain. I have also learned that diet tends to trump exercise - in other words, I find that I get in more trouble with inconsistent dietary discipline than I do with inconsistent exercise discipline.

I know there is a lot wrapped up in all of this, and I've probably left some things out.  If you're looking to get into better shape, I hope my experience can help you make great progress.  If you have any questions, drop me a line via email (see my About page) or in the comments below.

Why Getting Out of Your Comfort Zones Can Make You Happier

What do you do when things are "going fine?" Think about it: generally speaking, you like your job; your boss and co-workers are cool (for the most part); you have a pretty short commute, and the work that you do is interesting and fulfilling. If all that is true, why do you catch yourself daydreaming throughout the workday about learning how to rock climb, or heading out for an epic road trip with some of your buddies?

Actually, the desire to try new things is a normal and natural feeling. As Life Hacker notes, stepping out of your daily routine can actually help you to be more productive and happier at work, as well as in the rest of your life.

Some of the many benefits of getting out of your comfort zone

By expanding your boundaries and taking on new hobbies and interests, you can actually learn to handle any and all of life’s uncertainties. Whether it’s signing up for a cooking class or deciding it’s finally time to take those sky diving lessons, you are ultimately challenging yourself to do something you normally wouldn’t. Once you start stepping out of your comfort zone, you’ll probably find it gets easier to do, in part because you’ll get used to that vague sense of anxiety and fear that trying new things can cause. Over the long term, learning new skills and experiencing all sort of adventures can even help you to become more creative, as well as broaden your mind.

Fortunately, getting out of your comfort zone doesn’t have to be difficult and there are several simple changes you can make to help you ease into the idea of breaking from your comfortable routine once in awhile. Consider the following:

Vary your everyday routine

Stepping out of your comfort zone doesn’t have to involve stepping out of a perfectly good airplane to free fall into space — unless you want it to, of course. As it turns out, even some seemingly simple and innocuous activities can stretch the bounds of your day to day life and open you up to new ideas and experiences. For example, if your commute doesn’t involve only freeway driving, consider riding a bike to work every day for a week. Give up your Wednesday-is-pizza-night tradition once in awhile and try a cuisine that is new to you, like Indian or vegetarian. If you normally wait for a movie to come out on DVD before seeing it, head to your local theatre and catch a matinee of the latest comedy or adventure — and don’t read the reviews first, just go and have fun. These small but different activities can help to jump start your creativity and help you see the world in a different way.

Try a new hobby

Another great way to step out of your comfort zone is to take up a new hobby. As Thought Catalog notes there are plenty of fun, new activities that you can try. If you have always wanted to learn a new language, Duolingo offers free language courses in Spanish, French and more (my daughter loves their Spanish lessons, by the way). If you daydream about owning a motorcycle, why not turn that fantasy into reality by joining a motorcycle club? You can purchase a pre-owned bike or a basic model and then shop for accessories at an affordable company like BikeBandit.com. Once you have your needed gear, look up local clubs that will introduce you to new community of people and some like-minded souls who love the feel of the wind in their face. Other ideas include checking out the community center calendar for dance or cooking lessons or joining the choir at church and giving your pipes a good workout. If you love animals, try adopting a new pet. All of these activities will provide you with new experiences that will help make leaving your predictable routine a positive and desirable thing.

Volunteer

Finally, think about volunteering to do something fun that helps others. Personally, I spend a lot of my time volunteering at a Boy Scout Horse Ranch which allows me to get outdoors, do some physical labor (very different than my routine during the week), and help young men and women develop leadership skills. It is extremely fulfilling.

Whatever you decide to do, don't just do "the usual" - adding some new variety to your life can do wonders for your outlook.

Sharper Minds Through Video Games?

I play a lot of video games during my travels - it is a great release to unwind in my hotel room, and I find it very relaxing (yes).  I flit from one to another quite often, but my current favorites are Borderlands 2, Diablo III, and Call of Duty: Black Ops.  I also tend to apply lessons I learn from video games into how I view the world; for example, I have given multiple talks about what information security can learn from video games - such as this brief talk the RSA Security Conference earlier this year).  

With that in mind, I wanted to make sure I wasn't deluding myself - to find out if there really is something to this "learning from video games" thing I preach about all the time.

According to the Entertainment Software Rating Board, 59 percent of Americans regularly play video games, with the industry earning more than $10.5 billion in revenue annually. The survey also showed 44 percent of respondents play video games on their smartphones and 33 percent play on wireless devices. The rise in popularity of gaming has also led to the rise of studies investigating the potential negative effects they have. The Ohio State University found an increase in violent video game playing resulted in a spike in aggression.  

For what it's worth, I can definitely tell the difference between video games and reality and I think this resultant increase in aggression might be true of any competitive activity, such as organized sports.  Of course, that is just my theory...  

Since I know I benefit from playing video games and I don't feel they are harming me, I was curious about the "other end of the spectrum" when it comes to the impact of video games.  As it turns out, more researchers are looking into how video games can benefit us and report surprising results. Boosting memory, delaying cognitive decline and increasing multitasking ability and confidence are just some of the ways we can benefit from regularly playing video games.

Boost your memory

Recent studies from the Georgia Institute of Technology show gaming won't necessarily improve reasoning and problem solving, but can help boost your memory. Working Memory Capacity (WMC), is our ability to recall information relatively quickly even while distracted. The study showed that gaming can help strengthen our memory skills, along with our ability to work on a variety of tasks or switch between them quickly.

That makes sense, since practice with just about anything - including retention of data - tends to improve your abilities in that area.

Prevent cognitive decline

Playing games and using the computer may help prevent cognitive decline and preserve brain function. Staying mentally and physically active — whether by socializing, exercising or playing games — could also delay the onset of Alzheimer’s. Game resources like iWin carry a variety of puzzle games and mind teasers that could help strengthen memory, improve hand-eye coordination and encourage problem solving on convenient mobile devices or tablets.

I used to play Brain Age on my Nintendo DS to help in this area, and I know people who swear by Sudoku and other puzzles as a way to keep their memories and minds sharp.  I say you enjoy it and it doesn't cause any harm, why not?

Improve Multitasking

Researchers at UC San Francisco discovered video games, especially 3-D varieties, can actually improve overall cognitive performance in older, healthy adults. Senior citizens who played the games for 12 hours over the course of a month showed an improvement in working memory and sustained attention. Their ability to multi-task also improved as they became more skilled at switching focus during their gaming activities.

Of course, we can't truly "multi-task," but the better we can context switch and get back on our mental feet when switching from one task to another, the better.  I've noticed that my eyes take longer to adjust from close vision to far vision as I get older, and I suspect that resistance to switching from one context to another is a challenge from a mental perspective.

Build Confidence

Scientists at the University of Essex explored if people's self-esteem improves while gaming because it gives them the chance to experiment with characteristics they envision their ideal self possessing. The Researchers discovered gamers enjoyed gaming the most when there was little overlap between their actual and ideal self. Participants reported feeling better about themselves after playing with the personality traits they wanted, such as being outgoing.

I definitely agree with this.  Even though it is an artificial world, I find that taking risks in video games makes it easier for me to take risks in the real world - it can help you feel less anxious in the face of the uncertain.

Improve your vision

While some say excessive video gaming can hinder your eyesight, some new studies show the opposite to be true. Researchers at the University of Rochester discovered action video gamers who play a few hours a day over a month improved their vision by 20 percent. This improvement came from being able to pick out letters from a clutter of images. Gamers played for about 30 hours and saw a significant increase in their vision's spatial resolution.

Again, this feels right to me.  Not only do video games improve my reaction time, they force me to expand my attention to take in more things - this is true from a visual point of view, but also from an overall situational awareness perspective.  I need to keep tabs on where I am, how I'm doing versus my objectives, how the others in my party are faring, pay attention to new threats and opportunities, etc.

The bottom line

OK, so maybe I'm guilty of contrived rationalization, but in my book, the data says playing video games is good for me.  Enough said - I'm sticking with it!
