A little extra boost can lead to incredible possibilities. When you ride an electric bike, there’s no ride too long, no load too heavy, and no place your legs can’t carry you. Ditch the daily traffic jam, get more exercise, and feel great about treading more lightly on the planet. And best of all - have a blast along the way.

How pedal assist motors work
Electric bikes work by using an electric motor and battery to help you power your bike. On pedal assist e-bikes, you control the amount of power the drive system provides and the assist only kicks in when you pedal. The motor amplifies the power behind each of your pedal strokes, providing a natural riding feeling that makes it seem like your legs are supercharged!
Some manufacturers make e-bikes that use a twist throttle to engage the drive system. With these bikes, you don’t have to be pedaling for the motor to be engaged. This can be dangerous since it’s easy to get out of control if you’re not paying attention. We only make pedal assist e-bikes, because they feel the most like a regular bike and help riders feel more in command of their ride.
Parts of an electric bike
Mid-drive pedal-assist motors are located by your pedals. They provide a stable center of gravity, are easy to shift on hills, and feel natural while pedaling. Depending on the model, they output 250-350 watts and can assist up to 20 or 28 mph.
Rear hub motors
This type of pedal-assist e-bike features a motor encased in the hub of the rear wheel. They are generally more affordable and lightweight, making it easier to find one within your price range so all you have to do is hop on and go.
Displays and controllers are what you use to see and adjust your e-bike’s settings. They make it simple and easy to change your level of assist, see your speed and distance, and check how much battery power you have left.
Batteries are the biggest factor in determining how far your e-bike can go. The higher watt hour (Wh) your battery, the more power capacity. And bikes with Trek's Removable Integrated Batter (RIB) system make it easier to take along and charge up.
The general range estimate for an electric bike varies from 20-100 miles on a single charge. Yes, it’s really wide! That’s because there are so many factors that determine your range- some you can control, some you can’t. Those you can include the size of your battery, the efficiency of your motor, the level of motor assist you select, and how much weight you’re carrying. Those you can’t include wind, weather, temperature, and terrain.
How batteries affect range
The bigger your battery, the more capacity you have to go farther or go faster. Battery power is measured in watt hours (Wh), the higher the Wh the bigger the battery capacity.
How level of pedal assist affects range
Your range is directly affected by the assist mode you pick. For example, eco mode provides the least amount of assist, draws the least amount of power from the battery, and gives you the longest range. Turbo mode provides the most assist, draws the most power from your battery, and will drain your battery the quickest.
