Focus Jam2 7.8 Electric Mountain Bike 2023

Delivering great value and powerful performance, the Focus Jam2 7.8 Electric Mountain Bike is your ticket to riding further and faster than ever before. Lightweight and durable, the aluminium frame features 150mm of F.O.L.D suspension, which provides supple traction and progressive bottom-out resistance. A DVO Diamond E3 fork, also with 150mm of travel, takes the sting out of heavy hits, and 29” wheels encourage fast and confident riding. 

The Shimano Steps EP8 250 watt motor system provides 85Nm of powerful torque and a range of assistance settings for additional power up to a maximum speed of 15.5mph / 25kph. This is paired with a 720Wh battery for long-lasting performance, while a Shimano SC-E5003 head unit displays key data metrics such as remaining range, battery percentage and speed. Maxxis tyres deliver premium performance on loose, technical terrain, and the Shimano SLX/Deore drivetrain is a proven choice, offering smooth, precise shifts across the wide 12-speed range. Hydraulic disc brakes take care of stopping in all conditions, for confidence at speed, while the inclusion of a dropper post means the saddle can be dropped at the push of a lever, allowing optimal body positioning for big drops and steep sections.
