Customized Fat Tire Electric Bike A Wide Variety of Motors and Batteries E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist but are less reliable or powerful. Some, like the Yamaha system, have more torque, and others, like Bosch鈥檚 Active Line, are nearly silent. But, generally, all four make good options. Look for motor output (in torque), which will give you an idea of total power. Just like car engines, more torque equals more power off the line and more boost to your pedaling. But watt hours (Wh) is perhaps a more important figure to use鈥攊t takes into account battery output and life to give a more accurate reflection of power (higher Wh equals bigger range). Battery Range For many bikes, battery range is more important than total power (because they鈥檙e all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist that kick in anywhere from 25 percent of your pedal power to 200 percent. Consider how fast the battery takes to recharge, especially if you鈥檒l be using your bike for long commutes. And remember, if you won鈥檛 settle for anything less than turbo, you鈥檒l get the least amount of range (but the most amount of fun!) your battery offers.
