Range Boost seamlessly attaches an extra 500Wh battery to compatible Trek electric bikes for up to twice the distance and time between charges. It’s ideal for riders who want to ride longer, commute farther, and adventure bigger.
All Range Boost compatible e-bikes come with a long-range Bosch battery that's fully encased in the frame thanks to Trek's Removable Integrated Battery (RIB) system.
Range Boost adds a second battery to your e-bike so you can go even farther. Plus, it sits on top of your down tube so it won't get in the way of your bike's original RIB battery.
How much farther can I go?
Twice as far as before!
With Range Boost, you’ll be able to go about two times farther than you would with just one battery. We say "about" because there are so many factors that affect range—including the motor you have, the level of motor support you use, and wind and weather conditions. To help you plan your trips, you can reference the estimated range chart below and use Bosch's range assistant tool to calculate your approximate range.
