Us the Bosch Flow app to customize your motor's assist behavior, track your ride stats, and integrate your data with your favorite activity tracking apps.

Due to supply-chain issues, Specs are subject to change without notice.

Trek has auto-filled the variables for this bike model and the average rider, but you can make adjustments to get your most accurate estimate.
The new eBike Flow app turns your ride into a personalized experience. Use it to customize your motor's assist behavior, track your ride stats, and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.
TyreWiz monitors your tire pressure while AirWiz monitors your fork and shock pressure. Set your desired pressure in the SRAM AXS app and then just check the lights before each ride—red means you need a pump, green means go ride.
