Orbea Keram 30 Electric Mountain Bike 2022
As your ticket to adventure, the Orbea Keram 30 Electric Mountain Bike is a fast and comfortable choice for mixed terrain exploration. Capable of riding singletrack, cycle paths and city commutes, this model is a versatile choice, with its sport geometry making it easy to get on and go. Ideal as a first electric bike, the Bosch motor and battery system is reliable and integrated, hidden within the bottom bracket and downtube to keep it safe from harm.
The Bosch Active motor delivers natural assistance up to a maximum speed of 15.5 mph / 25 km/h, helping you summit steep hills and to cruise along the flats. A 400Wh Bosch Performance battery provides a wide range, and the Bosch Purion display highlights key metrics such as speed, range and distance. A choice of power modes ensures a perfect balance between range and power, and the battery is easily removable without the need for tools.
Convenience is key with the Keram lineup, and this model features a built-in kickstand, reliable Shimano drivetrain and fast-rolling 29” wheels (27.5” in size S) to improve your cycling experience. Powerful hydraulic disc brakes provide ample stopping power for the additional weight of a motor and battery, and the 10-speed drivetrain complements the motor with its wide range of gears.
