Powerful, Built To Roam

This hardtail trail e-bike is built for riders who love playful handling and confident control. Its aggressive geometry makes it ideal for technical trails, fast descents, and spirited day trips. Powered by the lightweight and quiet Shimano EP6 motor, it delivers smooth support with 85Nm of torque. Paired with a fully integrated 504Wh battery, you can ride up to 70 miles* on a single charge.

A 150mm dropper post (170 mm on larger sizes) adds flexibility on steep terrain, while 29" wheels roll fast and smooth over less demanding sections. It’s a bike that’s ready for adventure—wherever the trail leads.

Frame & Fork

This trail e-bike frame is built for control, durability, and versatility. Crafted from custom-shaped 6061 T6 aluminium with smooth welds, it features Trail Ultimate geometry for confident handling on technical terrain. The Shark Spine EVO design supports both 29" and 27.5+ wheels, giving riders flexibility in setup. BOOST 148×12 rear spacing adds stiffness, while internal cable routing and second-generation battery integration keep the look clean and modern.

The RST Vibe suspension fork delivers 140mm of air-sprung travel with a tapered steerer—ideal for absorbing hits and maintaining precision on demanding trails.

 
 

Drivetrain

This e-bike features a simple and reliable 1x8 microSHIFT Acolyte drivetrain, offering a 383% gear range with a 12–46T cassette—ideal for everyday riding and light trail use. The RapidFire-style shifter delivers smooth, intuitive gear changes, while the Acolyte rear derailleur keeps the chain stable across varied terrain.

A 34T chainring paired with the wide-range cassette gives you the flexibility to climb hills and cruise comfortably. The Shimano EM600 crankset and durable KMC e8S chain round out a low-maintenance setup that’s built for ease of use, making it a great choice for riders who value simplicity and control.

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.
