Super73 S2 SE: the electric fat bike (electric bicycle) with a café for demanding riders

The Super73 S2 SE is an electric fat bike—a pedal-assist electric bicycle—equipped with a removable 960 Wh (48V 20 Ah) PRO 1000 battery with 21700 Li-ion cells, a 48V 250W EPAC brushless motor with torque sensor , and 20-inch x 4.5-inch front / 5-inch rear Maxxis SuperSucker tires . EPAC compliant, it can be ridden without a license or registration plate in France and Europe, with assistance up to 25 km/h.

6061/7005 aluminum frame and two-seater café racer design

The Super73 S2 SE is built on a 6061/7005 aircraft-grade aluminum alloy frame with fully internal wiring, preserving the clean lines inspired by 1970s café racer motorcycles. The motorcycle-style raised handlebars, the dummy fuel tank integrating the battery, and the two-up seat (78 cm seat height, recommended height 1.45 m to 1.95 m, payload 147 kg) define an instantly recognizable geometry. The 20-inch x 100 mm alloy wheels with lightning bolt cutouts and the high-power triple halo LED headlight complete the S2 SE's distinctive look, day and night.

Adjustable 120mm air fork: preload, compression, rebound

The S2 SE features a 32mm air-suspension front fork with 120mm of travel, adjustable for preload, compression, and rebound damping. This level of adjustability allows for precise tuning of the fork's behavior to the rider's weight and the type of surface—asphalt, cobblestones, or mixed trails. The rear suspension remains rigid, keeping the weight down to 33 kg including the battery .

PRO 1000 battery, 960 Wh, 80-120 km range and 8 speeds

The 960 Wh PRO 1000 battery is the largest in the entire Super73 Z and S range. It delivers a range of 80 to 120 km depending on the PAS mode (up to 120 km in PAS 1), and is removable from the frame for charging in 6 to 7 hours. The brushless motor with torque sensor modulates the assistance according to the force applied to the pedals, for a progressive riding feel. The European version features an 8-speed mechanical derailleur , without a throttle, compliant with EU regulations.

180mm hydraulic brakes and Bluetooth connectivity

The front and rear 180mm hydraulic rotor brakes ensure consistent braking power in all weather conditions. The smart LCD screen, connected via Bluetooth to the Super73 app (iOS and Android), provides access to four PAS levels, turn-by-turn navigation, trip statistics, and OTA firmware updates. An integrated rear brake light completes the lighting package.
