Taking You Further

This new e-bike is built to take you further, with a powerful Bosch Performance Line motor and a fully integrated 625Wh battery offering up to 90 miles* of range on a single charge. Paired with a Shimano CUES 1x9 drivetrain, it opens up new possibilities for mountain biking and off-road exploration.

Wide tyres provide grip and confidence on wet, technical terrain, while thoughtful details like a BlockLock headset, rear frame protection, and mounts for two bottle cages ensure durability and convenience. Every element is designed to support your ride, wherever it takes you.

Frame & Fork

Built for sporty off-road riding, the frame combines lightweight 6061 T6 aluminium with smooth welding and a purpose-driven eMTB geometry. It's built with Bosch's PowerTube 625Wh battery system, with internal cable routing that keeps the lines clean and protected. Whether you're climbing trails or cruising forest paths, the frame delivers confident handling and long-distance comfort.

Up front, the Suntour XCR32 suspension fork offers 120mm of travel to absorb bumps and rough terrain. Its tapered steerer and Boost axle (15x110 mm) add stiffness and control, making it a solid match for adventurous e-MTB riders who want performance without compromise.

Drivetrain

This e-bike features a dependable 9-speed Shimano CUES drivetrain, built for smooth shifting and everyday versatility. The RapidFire Plus shifter offers quick, intuitive gear changes, while the rear derailleur keeps the chain stable and quiet-even on uneven terrain. With a wide-range 11-46T cassette paired to a 38T chainring, you'll have the gearing to tackle steep climbs, rolling paths, and urban routes with ease.

The lightweight alloy crankset and durable Shimano chain round out a setup that's designed for low-maintenance performance and confident riding-whether you're commuting, exploring, or heading off-road.

Range

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.
