The world’s lightest electric mountain bike

Third Quarter 2022 Editor's Choice Electrical switching & drive systems & components

Swiss bicycle manufacturer Thömus is launching the world’s first full suspension cross-country electric mountain bike weighing less than 15 kg. This record-breaking weight is made possible by the small and efficient maxon Bikedrive Air drive in the extremely lightweight Thömus ultra-high modulus carbon frame. With a slim, rigid frame, the Lightrider E Ultimate is a real racing bike that can be manoeuvred easily and agilely over any terrain.

The barely noticeable additional weight of the maxon drive of only 3,5 kg, in combination with superior carbon technology from Thömus, delivers a ride that feels as natural on the trail as on the bike of overall World Cup winner, Mathias Flückiger. As soon as you begin to climb, the Lightrider E Ultimate feels as if a tailwind is gently pushing you uphill, making it perfect for training or riding in a group. The unique freewheel technology of the maxon system ensures natural transitions from supported to non-supported riding. The result is an e-bike with the perfect balance between weight and agility that feels just like a normal bike.

maxon’s experience in the development of drive motors for Mars rovers is reflected in the system’s compact size, which allows the battery to be integrated invisibly into the frame. Only an inconspicuously integrated control element on the top tube hints at the extra power hidden in the bike. Equipped with a 250 Wh battery and an optional range extender with an additional 250 Wh capacity, technically challenging trails can be tackled with ease.
