Powerful And Natural

The Shimano EP8 drive unit is both powerful and quiet, offering a natural riding experience with significantly enhanced power. It features a 504Wh battery that delivers up to 70 miles* of range on a single charge. Integration has been taken to the next level, with the battery, wiring, and cables seamlessly hidden in the cockpit. Equipped with Shimano Deore 1x11 gears, practical ONE accessories and 2.6" wide tyres, it provides exceptional cross-country capability and comfort.

Frame & Fork

This e-bike frame is built for serious off-road performance, combining lightweight Alu X6 Ultralite construction with advanced eMTB geometry for confident handling on technical terrain. It features a sleek integrated battery design, internal cable routing and Boost 12x148 mm rear spacing for added stiffness and control. The SR dropout and dropper seatpost readiness add versatility for trail upgrades and accessories.

Paired with the RockShox Judy Silver TK suspension fork, you get 120 mm of smooth SoloAir travel, a tapered steerer for precision, and a 15x110 mm Boost axle for solid front-end stability—perfect for demanding trail conditions.

Drivetrain

This e-bike is equipped with a robust 11-speed Shimano Deore drivetrain, built for smooth shifting and confident off-road performance. The RapidFire Plus shifter delivers quick, precise gear changes, while the Shadow Plus rear derailleur keeps the chain stable and quiet—even on rough terrain. A 34T chainring paired with the wide-range 11–51T cassette gives you the gearing to tackle steep climbs and fast descents with ease.

The Shimano crankset and KMC e11T chain complete a setup that’s designed for durability, efficiency, and trail-ready reliability—perfect for riders who want control and versatility wherever the ride takes them.

All electric bikes specify a maximum mileage range achievable on a single battery charge. This represents the furthest distance under optimal conditions; however, several factors can influence this range:

  • The combined weight of the rider and any luggage.
  • The assistance mode selected.
  • The cycling route (e.g. type of terrain and inclines).
  • Temperature and climate (e.g. cold weather will decrease the performance of the battery).
  • Tyre pressure.
  • Wind speed and direction.

When you purchase a bike from Halfords, our support continues beyond the sale. We offer optional CycleCare plans for either 1 or 3 years, ensuring your bike remains in top condition with regular maintenance and expert care.
