Orbea Keram 30 Electric Mountain Bike 2021
Designed to help you ride in comfort and really enjoy your surroundings, the Orbea Keram 30 Electric Mountain Bike has a reliable Bosch motor and sturdy aluminium frame. 100mm of front suspension through the SR Suntour fork softens bumps on the trail, boosting comfort and control.
Fast-becoming the industry's go-to e-bike motor supplier, Bosch is the envy of its competitors. Here, they supply their fantastically smooth Active motor, with assistance of up to 40Nm of power. Once you reach 25km/hr, the motor cuts out and becomes barely noticeable, with minimal resistance through the cranks. The 400Nm battery has enough power for an average of 71km, so even the most adventurous of riders can enjoy a full day on the trails.
With a Shimano Deore 10-speed gearset, you can be assured of quality shifting, while the Shimano MT210 hydraulic disc brakes allow for superb braking modulation. The size Small comes with 27.5" Black Rock wheels, while the rest of the range comes with 29" option, allowing for a similar ride-feel right across the range.
