Trek Rail 9.9 Xx1 Axs Gen 4 Mountain Bike
Removable Integrated Battery
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.
Bosch Performance Line CX motor
Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
Bosch Mini Remote
The compact, ergonomic Mini Remote lets you easily change assist level, activate Walk mode, or turn on optional lights, all without moving your hand off the handlebar. Plus, it’s wireless and connects with your System Controller via Bluetooth
Bosch System Controller
The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. It’s integrated into the top tube so it’s out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.
RockShox AirWiz and Quarq TireWiz
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.
Bosch eBike Flow app
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.

Good stock availability, reasonably competitive prices.
It’s my local bike shop therefore counter collection is handy.
Many staff are also cyclists themselves and always seem happy to offer advice when asked.
