This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection - our Direct-Drive motors are now all High-Torque 6x9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the...
This 48-volt mid-motor electric mountain bike is a great value. The X-Treme Summit is packed with top-of-the-line components from Shimano, Suntour, Tektro, Samsung, Kenda, Velo, and more. With a top speed of 28 mph and tremendous torque from the mid-frame mounted motor, it conquers rough terrain and inclines like a champ. Pull power from the motor by pedal assist and throttle.

Upper Dublin Township in Pennsylvania is initiating a pilot project to gauge the advantages of using electric bicycles. The e-bike, as they are more commonly known, will be used for police work and for the Township’s Sitewatch program, which patrols and monitors parkland and playing fields. The people behind the program believe the electric bike could prove to be a useful tool, giving police officers and parks personnel a clean,...
The Panasonic Akku cells used in this pack are among the best lithium polymer cells Panasonic makes, which is one of the finest names in the industry for lithium battery technology. This means the pack will give you years of long life without worries about a battery fire or breaking down. The battery, along with the rest of the components of this electric bike, come with a 2-year warranty. The bike comes with a relatively fast 200-watt charger that will refill this pack in only 2.5 hours. And the battery locks into the bike with a key lock, good for preventing theft. The battery pack includes a built in battery meter that shows battery level whether it’s on or off the bike.
Out on the road the Soho is easy to fire up, just press the button hidden under the top tube (a nice discreet touch), you’ll then get a set of five top-tube mounted LED’s light up to give you a charge indication. First impressions were that the engagement of the motor is a little jerky in tight traffic (tested in central London) and you could find yourself pulled toward the cars you’re weaving though at slow speeds - unless you’re feathering the brakes.
ELECTRONIC CONTROL  The Zero-Smart-Start speed controller delivers ease of use and smooth drive control and offers a multi-function variable speed output.  It is state of the art, producing consistent efficient power.  The automatic Pedal Assist mode produces a power burst that dramatically assists the pedaling effort.  The Zero-Smart-Start electronic throttle control allows the rider to relax and not pedal at all. 
After you decide which style of e-bike you want, consider the class. In the US, there are three classes defined by the type of assist and how fast the motor will propel you. Most electric bikes sold are class 1 or 3. Class 1 bikes have a motor (max 750w) that assists while you're pedaling, up to 20 mph. Class 3, also known as “speed pedelec” can also have up to a 750w motor, but it can assist you up to 28mph. Both of those are allowed in most states and cities without license. Class 2 have throttles that don't require you to pedal to get a boost. They're allowed on most streets, bike lanes, and paths, but less popular than the other classes and not covered much here (because we still love to pedal and the greater distances pedal assist bikes can cover).
