It's right for you if...

You ride rugged trails and you're ready to go further and faster than ever. You want the best trail bike capability, the latest in mountain bike and e-MTB tech and enough suspension to soak up the big hits and obstacles you'll encounter.

The tech you get

A durable Alpha Platinum Aluminium frame that fully encases a long-range 500Wh battery for great aesthetics and ride quality on the trail, a Bosch Performance CX motor and Purion controller. Plus, an e-bike optimised FOX 36 fork with thicker, stiffer legs, RockShox rear shock with RE:aktiv damper, grippy 27.5+ mid-fat tyres, e-bike specific Powerline Comp 40 wheels with a 54-tooth Rapid Drive hub, a Bontrager Line dropper post and a 1x12 SRAM GX Eagle drivetrain.

The final word

This e-MTB ticks all the boxes for rugged trail bike capability. It has high-end trail spec, long-travel suspension with advanced damper tech, upgraded Bontrager wheels and a powerful Bosch pedal-assist system. All together, that makes for a ridiculously capable performance ride that's the perfect companion for serious trail outings.

The Walkthrough

favorite_borderWhy you'll love it

  1. 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 to remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs
  2. Longer travel suspension and 27.5+ mid-fat tyres are the perfect combination for traction, stability and capability on rough trails
  3. An advanced spec including e-MTB-specific parts and Trek's RE:aktiv damper take this model to the next level
  4. It rides like a mountain bike because it is one: it has the same frame and suspension tech that we've refined in our decades-long trail heritage

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.

ABP

Our patented Active Braking Pivot allows your suspension to work freely whether you’re on the brakes or off. It’s smooth, controlled suspension that’s at its best all the time.

Bosch Performance CX

Bosch’s Performance CX line is made for rugged off-road use with a maximum torque of up to 75 newton metres, sustained power into the high cadence range for sporty acceleration and a sleek mid-mount motor for ideal weight balance and obstacle clearance.

Bosch Purion Display

Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.

Motor Armor

This unique protection shield made of lightweight but robust aluminium protects the motor against stones.

Alpha Platinum Aluminium

Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.

Boost148/110

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.

Bosch PowerTube 500Wh

This latest Bosch battery sets the standard in integration and has 500 Wh for an extended range.
