How does an e-MTB work?

Electric mountain bikes have a small motor under the frame where the cranks are. A rechargeable lithium-ion battery powers the motor. The motor only provides power when you are pedaling. It adds power to each of your pedal strokes, so it feels like pedaling a normal bike, except with supercharged legs. You can control how much power the motor provides with a handlebar-mounted remote. Trek e-MTBs with Bosch drive systems let you choose from three different levels of assist power. Or you can use the set-and-forget e-MTB mode that automatically adjusts the assist to deliver just the right amount of power for every situation on the trail.
