eBike technology from Bosch - hands-on

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.

Do's and Don'ts for Password Creation

In today’s world of online shopping, online banking, cloud data management and Internet-based teleconferencing, protecting yourself is more important than ever. The recent batch of stories relaying the horrors of celebrities and corporations being hacked and sensitive data being exposed only serves to highlight the necessity of having good security. The first place to start is with your own passwords.

People assume that if something has a password, it is protected. This is not always the case. Many hackers are adept at guessing passwords, giving them total access to all of your personal information.

How can you make your password more secure? There are several techniques you can employ, all of which will increase the strength of your passwords and help keep you and your information safe and secure. Here are a few do’s and don’ts.


Do go long. The longer the better. While you don’t want to go crazy because long passwords can be impossible to remember, make sure yours is longer than nine characters. Can't be bothered to come up with your own unique passwords for every site you belong to? Check out Norton's free password generator where you can specify length and contents at the click of your mouse.

Do mix it up. Have a combination of lower case letters, capital letters, numbers and symbols, preferably at least two of each. And don’t put them in a predictable order (in other words, don’t start your password with a capital letter).

Do use an anagram. Create your password using an anagram or sentence. “W!t2gMp&#b4uX” may look impossible to remember until you realize it stands for “Wait! try to guess MY password and numbers before u FAIL.”

Do take precautions. Remember that even the best password is not foolproof. For added protection, take advantage of services like LifeLock. It'll keep track (and alert you) of any suspicious activity on your accounts and will help you get your life back on track if identity theft happens to you.

Do use a password manager. Keep your passwords in a password vault (such as 1Password, LastPass, or a similar product). These products allow you to create random, complex passwords for each web site and stores all of them in a secure manner. 

Do change it regularly. If you've had the same password for more than a year, it is probably time to change it. I recommend a minimum of once per year - more often for critical sites. For example, I know someone who changes their online banking passwords at every time change (the same time he changes batteries in his smoke detectors). That is a good habit.

Use two-factor authentication, if it is available. More and more sites are offering two-factor authentication in which you not only enter a password, but you have to enter an additional verification code that changes all the time. The most common method these days is to send a text message to your mobile phone with a code that must be entered to complete the login process. Many banks and payment processors (such as PayPal) offer this as an option - it is easy and adds a lot of security to your account, and is highly recommended. 


Don’t use common passwords or familiar patterns. Using common passwords that are easy to remember might sound like a good idea, but they are often the first ones tried by hackers. Don’t use things like “iloveyou” and “password1." Check out the 25 worst passwords and read as a cautionary tale.

Hackers are also adept at using familiar patterns to guess passwords. Putting a capital letter at the beginning, numbers at the end or finishing with an exclamation point are all very common and predictable.

Don’t use your names or numbers. Avoid using common names or people in your life as part of your password. Also avoid things like the street you live on or the company you work for. All of these can be found out by doing a little digging.

Same goes for any numbers that can be associated with you or someone close to you. Birthdays, anniversaries, addresses, social security numbers, etc., all of these are easily discovered by potential hackers.

Don’t overlap. Using the same password for multiple devices or multiple websites can put you in danger. It may be a pain to remember all of them, but if a hacker is able to deduce one of your passwords, it is the first thing he will try on the rest of your security locations.  See the "Do" about password managers for ways to make this easier. 

How To Go From Rookie Engineer To Valuable Asset

I have a position on an industry advisory board for a local university's Engineering department, which means I get to hear a lot about the challenges of newly-graduated engineers who are looking for jobs. I've also had the chance to speak with some of the new graduates who were able to get engineering jobs, but are wondering how to make their mark (or at least fit in among their corporate peers).

Imagine this: You've just spent four to six years getting a degree or two in engineering. That's a solid decision considering the U.S. Bureau of Labor Statistics reports that all engineering fields have a high median salary and show better than average growth over the next decade. Of course, getting the engineering job is much different than excelling at the engineering job. As a new engineer, your fresh education is your greatest strength and, although only time will make you a veteran, there are ways you can further advance your knowledge once on the job to position yourself as an indispensable member of the team.

Learn The Jargon

All facets of engineering are full of technical language, some of which you learned in school or gleaned from technical writings, and some that you will need to research or learn as you go. Depending on the field and your role within the organization, there is differing terminology; for example, the engineers in the non-destructible testing (NDT) department have idioms that differ from the R&D group. Pick up some of the jargon from resources like The Most Used Engineering Terminology Defined list on StruCalc or go even further and read the policy and procedure manuals word for word, as this is where engineering acronyms are born.

I happen to work with a lot of software engineers, and we have our own jargon - not only about engineering and software development, but also about the processes surrounding the coding (think Scrum and Agile). We don't expect everyone to know our jargon, but we're suspicious of anyone who doesn't :-)

Know Your Journals

For many fields, scientific, peer-reviewed journals are where the newest ideas are shared. Since new concepts are among the most valuable things you can bring to the table, stay abreast of the latest scientific literature. SJR ranks scientific journals by field, citations and country. According to SJR, the best journal for mechanical engineering is the Journal of Nature Materials which is a UK-based monthly journal that brings together multi-disciplinary articles on cutting edge material sciences. Electrical engineers may want to subscribe to the Journal of Nature Nanotechnology for its vanguard electronic sciences. I regularly read the IEEE Journal, for example.

Sites To Follow

In an online world, there are reputable websites for scientific literature and engineering technology, with one of the best for civil and industrial engineering being the U.S. Army Corp of Engineers website. Besides giving you a solid history of engineering, the Army Corp of Engineers is the final word in civil engineering, risk management and safety and occupational health.

For very different reasons, another site to follow is Engineering For Change. Not only does this website offer the newest engineering innovations across technical fields but it does it with a socially responsible, philanthropic agenda. Partnered with IEEE and Engineers Without Borders, Engineering For Change lets a rookie engineer networks with veterans around the world, building up his knowledge and support network.

Carve Your Niche

Having a specialization is a good way to become invaluable to your company. Within each brand of engineering, there are specialties that call for additional education. Quality assurance is one of the largest specialties, as every engineering concentration needs a quality assurance department or liaison. For example, rubber seal manufacturer Apple Rubber is QA certified in several areas; in aerospace, Apple Rubber is AS9100 certified; for medical components, the manufacturer is ISO 9001 compliant. They even have a certified cleanroom which is class 10000, ISO 7 compliant.

Each of these quality assurance specializations requires specific expertise, record keeping and detailed reporting. The Bureau of Labor Statistics lists quality assurance in each engineering sector, from electrical to industrial to computer.

Try to find a field or specialization that not only hold your interest, but maps to your talents. For example, if you have an eye for detail, QA (Quality Assurance) may be the specialization for you. If you are adept at chemistry, you may want to get into a laboratory environment creating coatings. In any case, deciding where you want to specialize - and doing that early in your education or career - can help you prioritize and come up with a plan for success. 

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 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.


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.

Don't be a victim in the eBay data breach

If you're an eBay user like me, you'll have seen the news about their recent data breach in which users' names, email addresses, physical addresses, phone numbers, date of birth, and encrypted passwords were taken.  As part of my day job, I have been involved in sharing information about this incident, and thought I would share some of my thoughts here.

From the information publicly shared by eBay, it appears that the data breach involved securely encrypted passwords, which makes it more difficult to gain access to users’ eBay accounts en masse, as it will require brute force decryption (i.e. high-speed guessing) to determine the specific characters in an individual's password.  If you use a simple and/or a short password, the chances of them guessing your password quickly are much higher and if you re-use that simple password on other sites, your risk goes up greatly.  Remember, once the attackers have your email address and at least one of your simple passwords at that point, they can start trying that combination on other sites to see if they can get lucky.

The fact that user email addresses, physical addresses, and dates of birth were taken in the breach is more concerning.  Criminals could use your personal information to masquerade as eBay customers on other sites, or perhaps use knowledge of that data to ‘social engineer’ their way into users’ other accounts on other services.  Unlike the passwords themselves, the other user-specific information was not encrypted and therefore could be easily reused by attackers.

eBay will ask you to reset your password - do it, even though it appears they will make this optional.  Furthermore, use a complex password - I suggest that you use a product like 1Password or LastPass to help you manage passwords online (I use 1Password, personally). These products can help you create a strong password by suggesting and saving a highly complex password.  Of course, you should also make certain you are not using your eBay password on any other sites.

Many eBay users also have their accounts connected to PayPal for payments (PayPal is owned by eBay, but their statements indicate that PayPal was in no way involved in the data breach).  For additional security, I recommend you make use of PayPal’s optional feature which uses 2-factor authentication to verify the users’ identity prior to making a payment (you can find more information on PayPal's site).  Given that PayPal is linked directly to your bank accounts, this is a best practice even if there had not been a data breach at eBay - I have been using this multi-factor approach for a couple of years and it adds an extra step in the buying process, but provides a great deal more security.

Finally, eBay users have long been a popular target for phishing emails, and users must be especially wary during incidents like this.  To be safe, do not click on links in emails about eBay security or password changes; instead, type the eBay URL directly into your browsers and log into the site that way to prevent disclosing your credentials to spoofed, malicious copies of the eBay site.
