Why Choose the Super73 S2?
Powerful motor and zippy throttle
The Super73 S2 is all about fun and power, provided by the 750W rear hub motor that assists up to 20 mph. You can ride in pedal-assist mode or use the throttle to rip down your favorite routes, all while staying within legal Class 2 speeds. A hallmark of Super73 e-Bikes is the battery pack that looks like a motorcycle fuel tank— the S2 model comes with a large 960 Wh battery for extended range.
Bold, retro motorcycle style
The cool aesthetic of the Super73 S2 is second to none, boasting retro flair and a rugged build. Different from most electric bikes, the S2 has a chassis-like frame with a fixed seat similar to a motorcycle or moped. The wide tires, battery pack, bright headlamp, and dual-crown suspension fork complete the café racer look. Read about why Super73 e-Bikes are perfect for West Coast riding!
Comfortable cruising
The Super73 S2 is unique because of the moped-style frame with a fixed seat position and long saddle. It’s a relaxed and comfortable riding position, especially while using the throttle to zip along city streets and local paths. It’s a one-size frame that fits most riders, though especially tall riders may bend their knees quite a bit when pedaling. The simple single-speed gearing, hydraulic brakes, and sturdy build further increase rider confidence while cruising.
