High Power Electric Bikes - How E-Bikes Work

Electric bicycles are one of the most exciting technologies currently available to bike enthusiasts. It's easy to understand why: nothing gets around the feeling of freedom that electric bicycles give their users. You simply don't have to worry about wearing your helmet, traffic laws, or find parking if you're riding an electric bike! Electric bicycles are terrific, but they lack something essential. Speed.

Motor Power Yes, high power electric bikes (<=1000W) do exist, but you have to do lots more paperwork and, again, require a permit. In the United States, the legal maximum electric bike engine power is 0 to 75W. Typically the heavier the bike, the more torque it requires accelerating; the more Speed it wants to achieve; however, the higher the engine speed, which will make the bike harder to control.

Top Speed, The maximum speed capabilities of cheap electric bikes are limited only by your imagination. Some can cruise along at 18 mph; others can reach speeds of well over 50 mph. What's important is that you get into the desired speed range, which will depend on your battery pack. Each cell has a different capacity and maximum performance range. There's also a limit on the overall top Speed. Electric bikes offer only a single speed.

Drive System These class 2 e-bikes come with either pedal-assist or throttle control. Pedal-assist operates on electricity supplied by the e-bike batteries. Throttle control works on your manual throttle control, similar to your motorcycle's throttle.

Motor Drive This type of e-bike is very similar to your motorcycle's engine in that it uses a chain to move the pedals. However, there is an additional motor drive system. Instead of a chain, there is a direct drive chain that is operated via a transmission. A flywheel is used to provide torque and is typically mounted on the front fork. Battery capacity for this type of bike will be minimal compared to other models.

Pedal Assist This kind of bike gives you a hands-free ride by way of a pedal-assist mechanism. The motor does all of the work necessary to propel you forward. So you can pedal yourself but without actually pushing the pedal to go faster! This is great for people who want an ebike conversion kit that allows them to pedal themselves but would prefer not to control the motor.
