The Surprising Health Benefits of an Electric Bike by Gretchen Reynolds. The New York Times, July 6, 2016. Electric bikes can encourage motorists back onto two wheels, with real benefits to their health.
As a power electronics engineer I had intended designing and developing a torque assist bike so was surprised to find that a few manufacturers brought them out in Europe recently. I bought a Raleigh Vélo Cité with a 36V 10Ahr lithium battery. I would never use a throttle or cadence type unless I was infirm and I am sure that torque sensing pedelecs will become the norm as prices fall.
I bought an OutlawSS which tops out at 28mph. I tried the “discreet” route as stated above but because of the blood-red color and design of the bike I attracted too much attention. It didn’t matter that I was keeping my (alongside the road) speed at 15mph, people (probably cycling enthusiasts or just haters) jammed on the brakes to check out wtf I was riding. One passenger (some teenager) even had his smartphone out and was either snapping pictures or getting video. Long story short, the officer that pulled me over said “no” to the bike and advised me to get an off-road sticker from the DNR and I’d be fine on ATV trails. He also said there have been numerous reports of “The guy on the illegal E-bike”. I was polite and got off with a warning. Haters gonna hate I guess.
Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don’t require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.

For the premium buyer, there’s the Faraday Porteur, the brainchild of Adam Vollmer, a mechanical engineer from Ideo, the famed design firm. First launched as a Kickstarter project last year, Faraday is now taking pre-orders for the Porteur, which is priced at $3,500. It weighs less than 40 pounds, features a leather saddle and bamboo fenders, and its Web site promises that it is “crazy fun.” Even more expensive is the $4,000 eFlowE3 Nitro from Currie, which was designed by a Swiss firm, Flow AG, and promises “fast, powerful and nimble handling.” And if you’ve really got money to burn, there’s a German e-bicycle called the Blacktrail BT-1 that claims a top speed of 65 mph and retails for $80,000. Think of it as the Tesla of electric bikes.
The CX1 builds on that success, adding a new more powerful brushless motor, an upgraded battery, a 21-speed gear system, and improved reliability. The Power Plus can be used simply as a traditional ‘pedal’ bike without any problems, however it also features other mode.
Even in Ohio, the laws between federal, state, and local on electric bicycles are a joke. I have a 100% tao tao electric power assisted bicycle and I have been ticketed in both Cleveland and Lakewood, where I live. Here is a picture of my electric bicycle and this has bicycle pedals.
Pedelecs are pointless. Most people who buy electric bikes want to cruise on electric and pedal just a little. Plus you can keep up with traffic better with throttle and more speed. Its actually dafer for you. Some pedelecs you never know when the darn motor will kick in. The pedelec sensor fails often. Its a nightmare for ebike companies to fix!
Established bike companies and startups are embracing ebikes to meet demand. About 34 million ebikes were sold worldwide in 2017, according to data from eCycleElectric Consultants. Most were sold in Europe and China, where the bikes already have exploded in popularity. In 2017, the U.S. market grew to 263,000 bikes, a 25% gain from the prior year.
Some assembly of your new electric bike may be required. Often, this merely involves attaching the front wheel, but assembly chores are sometimes more complex than that. Several manufacturers provide instructional videos to help owners with the task of e-bike assembly.
GenZe e-Bikes come in sizes to fit every shape. Height is usually the best gauge of size, but we also recommend comparing your inseam to the standover height if you’re considering the Sport or 201 models. The 200 series also comes with adjustable handlebars and a 4-way adjustable seat to get the perfect fit.
