Trek Rail 9.8 Xt 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.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
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.
Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.

I ordered a rear derailleur and cassette. Shipping to Australia was as expected. Pretty quick. Would use these guys again for sure.
