Focus Jam2 6.8 Nine 29" Electric Mountain Bike 2021
Looking to take on the UK’s best trails? The Focus Jam2 6.8 Nine 29" Electric Mountain Bike is your ticket to ride. Whether it's a spin around a trail centre or a back-country Welsh epic, the Jam2 will open up your riding and take it to new heights. 150mm of progressive suspension keeps you in control on the rough stuff, with Focus’s electric mountain bike specific F.O.L.D chassis guaranteeing premium all-mountain performance. Sensitive small bump compliance provides velcro-like grip, and is matched with an aggressive ramp up to prevent bottoming out on more demanding trail features.
The Jam2 is built to conquer the whole mountain, both up and down. 29-inch wheels give excellent on-trail capability, cruising over rougher terrain and reducing hangup, offering a stable ride that can only be found with the larger wheel size. 2.6” Maxxis Minion DHF tyres will have you ripping turns like never before, offering unreal grip on all trail surfaces. This wide width is the ideal companion for the extra weight of an electric mountain bike, giving improved support in the corners.
Motor duties are taken care of by Bosch, being specced with their premium fourth-generation Performance CX system. 250 watts of on-demand power meets 85 Nm of hill-climbing torque, making the race to the top of the climb more enjoyable than ever. To keep the Jam2 powered, Bosch’s latest Powertube battery is used. Packing 625wh will get you around all but the longest of rides with juice to spare, with the eMTB motor support mode automatically adjusting to your power input. Charging the Jam2 is a breeze, with both on and off-bike charging being available for the well-integrated battery.
Specification is taken care of by Shimano. Shifting is crisp thanks to their latest 12-speed SLX shifter and Deore XT rear derailleur combination, and four-piston BR-MT520 brakes pack the power necessary to stop on a dime. Wide Race Face AR30 offset rims offer plenty of support and stiffness in the turns, providing stability matched well by the 150mm travel FOX 34 electric mountain bike specific fork.
