Orbea Keram 10 Electric Mountain Bike 2021
With an upright position for better comfort and control, the Orbea Keram 10 is a superb electric mountain bike that inspires confidence to tackle new trails and head further offroad. The strong aluminium frame and powerful Bosch motor are the quality parts you need to ensure years of great service. With 100mm of travel, the front suspension tames rocks and ruts to help smooth out your ride.
When riding along a particularly tough section with lots of twists or sudden inclines, the Extended Boost mode of the Bosch Performance CX motor kicks in, effectively smoothing out the trail for a more consistent effort. The 500Whr battery can last around 65km, which is enough for even the most enthusiastic days out on the trails.
Quality Shimano components cater for your shifting and braking, with a Deore 10-speed gearset and powerful MT210 hydraulic disc brakes ensuring you can stop quickly and safely. Orbea's own Tryp wheelset is size-specific, with the size Small frame coming with 27.5" wheels, and all other sizes rolling on 29".
