It's right for you if...
You want more than just the added capability of electric-assist. You also want quality mountain bike parts that make the biggest difference on the trail, the user-friendliness of the Removable Integrated Battery (RIB) system, and the good looks that come with a battery that's fully encased in the frame.
The tech you get
A durable Alpha Platinum Aluminium frame that fully encases a long-range 600 Wh battery for great aesthetics and protection on the trail, a new Bosch Performance CX 250-watt motor that assists up to 25 km/h and an ergonomic Purion controller. Plus, a 120 mm RockShox 35 Gold RL fork with an ultra-plush DebonAir spring, Shimano 4-piston brakes, Tubeless Ready Bontrager Line Comp 30 wheels, a 1x12 Shimano SLX/XT drivetrain and a dropper post.
The final word
Quality trail bike parts, a powerful Bosch system and the streamlined looks and easy user interface of the Removable Integrated Battery (RIB). Plus, the dropper post and RockShox DebonAir fork give you a major upgrade in trail bike performance.
favorite_borderWhy you'll love it
- The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you’re pedalling, and has less drag when you’re not
- Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
- It's equipped with an external charging port for easy charging on or off the bike
- All sizes but L feature a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames
New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It’s also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It’s a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.
Will my bike have a curved top tube?
Smaller frames (XS, S and M) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frame (L) has a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Going for a long ride? Rack mounts make carrying accessories a breeze.
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. The rim strips are already installed; just add TLR valves and sealant.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.
This unique protection shield made of lightweight but robust aluminium protects the motor against stones.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
