How Fast is a Super 73 Electric Bike? Real-World Speed Explained

One of the most common questions riders ask before buying is, “How fast is a Super 73 electric bike?” Speed is a major reason why Super73 bikes stand out from traditional electric bicycles, and in real-world conditions, they deliver strong performance.

Most Super73 electric bikes are classified as Class 2 or Class 3 e-bikes, depending on region and settings. This means they are designed to balance power, safety, and legality.

Model	Top Speed	Class
Super73 ZX	20 mph	Class 2
Super73 S2	28 mph	Class 3
Super73 Rx/R Brooklyn	28+ mph	Class 3

In everyday riding, the RX and S2 models feel noticeably faster than standard commuter ebikes. Acceleration is strong, especially when using throttle mode, and hill climbing is smooth due to high torque output.

From a practical standpoint, Super73 bikes feel stable at high speed, largely thanks to their fat tires and long wheelbase. However, at speeds close to 28 mph, riders should wear protective gear, as these bikes are heavier and more powerful than average ebikes.

While speed is exciting, higher speeds reduce battery range and may affect legality depending on local ebike laws. Riders who want balance often limit speed for daily commuting.

Verdict:

Super73 electric bikes are among the fastest legal ebikes available, making them ideal for riders who prioritize power and thrill.
