Next level carbon Gravel eBike.

The gravel bike category is growing quickly as riders are enjoying the versatility of hitting light trails on the weekend, doing long distances on gravel roads, and going for long road rides during the week. For this purpose, the S-Electro Superfast is designed to be as comfortable on the road as it is on gravel. Superfast features the groundbreaking FSA System HM 1.0 250W hub motor, matched to an FSA System HM 1.0 250Wh battery with an integrated on-bike control unit.

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.


EPS Molded Carbon Fiber frame

Constructed through expanded polystyrene (EPS) moulding. Preform moulding allows precise, uniform (wrinkle-free) and repeatable execution of the lay-up schedule. Uniform fibres increase strength reducing irregularities.















  1. FSA hub drive motor means lower Crank Q-Factor and the ability to run a 2x crankset with matching drivetrain components
  2. Proprietary carbon, carbon and more carbon. More than just looking incredible, the Superfast is purpose built and spec'd for performance.
  3. Tyre clearance for up to 700C x 35C tyres.
  4. Full internal cable routing from control part to component
  5. Smooth shifting, quality, Ultegra 2x11 speed groupset
  6. Integrated headlight and taillights for super visibility




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.



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.



Superfast features a top-tube integrated stem with full internal cable routing from control part to component. Computer and light mount integrated to stem faceplate.



A proprietary fully rigid carbon fork is compatible with 700C x 40C front wheels. This fork is aerodynamically optimised, offering improved airflow. Compatible with 160mm flat mount disc brakes, the cable is routed internally, further enhancing looks and aero efficiency.



Being a bike that can shine both on and off road, the Superfast is designed to accommodate up to 700C x 40C wheels and tyres. That means you have ample options of either road, oversize road or gravel tyres to choose from.



Interchangable rear dropout - between 135x9 or 142x12 for conventional use means that the Superfast is extremely versatile.



Superfast is fitted with a high quality, reliable Shimano Ultegra 2 x 11 speed groupset and top end Surface carbon fiber cockpit components all round.



The LED colour changing top tube button makes changing modes intuitive and quick. And the colour means that you can see it in your peripheral vision, without having to look directly at it, meaning you can look at the trail.
