Audi is expanding its range of e-mobility products with the launch of a limited-run electric mountain bike.

Based around an enduro frame made from lightweight aluminium, it has a 36 V, 720 Wh Fantic Integra battery pack fitted within the frame, which supplies power to a Brose S-MAG 36 V, 250 W motor that delivers up to 90 Nm of torque.

The bike has four levels of electrical assistance: Eco, Tour, Sport and Boost. Eco has been calibrated to deliver maximum efficiency and range, while Tour brings a level of electrical boost. Sport has been engineered to add assistance for sport cycling, and Boost delivers the maximum level of electrical assistance for challenging routes.

A small digital display on the handlebars provides an overview of data such as battery charge and speed. When the battery charge drops to less than 10%, the charge level indicator will begin to flash.

The bike has a full suspension travel of 180 mm, wide wheels and off-road tyres. 

Three sizes are available, with prices starting from £8499.
