The Marlin+ 8 is an electric mountain bike that's ready to up your game on the trail. Its Bosch Active Line Plus motor gives you just the boost you need for getting up steep climbs and riding further, and doesn't break the bank, and a 120 mm suspension fork keeps handling smooth through the rough stuff. Upgraded components, like wide tubeless-ready wheels and tyres and a 12-speed Shimano drivetrain make this a trail-savvy ride that's ready to go anywhere.

A boost of power is just what you're after, but you don't drain the bank account. You want plenty of gears for riding all kinds of trails, and the flat protection offered by wide 2.6 in tubeless-ready wheels and tyres.

An Alpha Gold Aluminium frame with real mountain bike geometry and an air-sprung 120 mm fork. A reliable Bosch Active Line Plus 50Nm drive system capable of assisting you to speeds of 32 km/h. A compact Purion 200 remote with built in display and 400 Wh Powertube battery. You get 12-speed Shimano Deore shifting, hydraulic disc brakes and wide, 2.6 in tubeless-ready tyres that boost grip and help prevent flats.

The Marlin+ is the go-to for riders looking to dip their toes into the electric mountain bike world. Its trail-savvy frame gives you confident control, and a Bosch Active Line Plus motor offers enough power to take the burn out of long climbs.

The Marlin+ is easy to use with simple controls and intuitive support, so you can focus on the ride ahead, not complicated remotes
