Electric system with integrated lights

Superfast is fitted with the brand new groundbreaking FSA System HM 1.0 250W hub motor, matched to an FSA System HM 1.0 250Wh battery with a top-tube integrated on-bike control unit. With five assistance settings, an integrated torque sensor and two speed sensors, the system easily adapt to changing riding styles and conditions. When disengaged, the system has zero drag, for a natural free pedaling motion, and a low q-factor makes it feel like a normal bicycle. There is also a powerful app that works with the system. Superfast also has integrated lighting with a Spectrum ELITE 100 eBike headlight and a Garmin Varia™ RTL510 Radar Tail Light.

GEOMETRY

S-Electro Superfast has Endurance focused geometry for all day riding comfort. The slack head angle improves steering stability on rough terrain and also at high speeds.Short chain stays for improved air flow transition between frame and rear wheel.

INTERNAL BATTERY

Superfast conceals a 250Wh battery in a compact down tube. The battery can be charged on the frame, but is also easily removable to charge away from the bike, or to replace. Additionally, the system can take a secondary 250Wh expansion battery in the seat tube bottle mounts, to double the range.
