Is This The World’s Lightest E-bike?

Thömus introduces the 25 lb Swissrider

Swiss bike manufacturer Thömus just announced the Swissrider, a 25-lb commuter e-bike that they claim is the lightest on the market. That weight edges out the 26 lb, 14 oz LeMond Prolog we tested previously.

The Swissrider boasts a high-modulus carbon fiber frame with a Maxon Bikedrive Air mid-drive motor that puts out 300W at peak with 40Nm of torque, and there are battery options for 250Wh, 360Wh and 426Wh.  That system weighs in at 7.7 lbs, has a torque sensor for more natural power delivery, and is virtually invisible in the bike.  It has three preset modes: Cruise (gentle tailwind), Push (sport mode) and Blast (for steep inclines).

The bike comes standard with road tires, integrated lighting, and optional mudguard and rack. The bike can be spec’d with gravel tires, upright handlebar, or drop bar, with customization offered on components.
