What's the Fastest E‑Bike?

When we talk about the "fastest" electric bicycle, we have to acknowledge a crucial gap: the huge difference between legal limits and pure performance. In most parts of the United States, the legal classification system (Class 1, 2, 3) strictly caps the motor‑assisted top speed. Even for the most lenient Class 3 e‑bikes, the maximum assisted speed is 28 mph (about 45 km/h) – and that is typically pedal‑assist only, with the motor cutting out once you hit that speed. This means that if you want a street‑legal e‑bike, the speed ceiling is already fixed at 28 mph by law.

However, when we step away from public road regulations – for example, on private property or a racetrack – the definition of "world's fastest e‑bike" changes completely. In that world, the line between e‑bike and electric motorcycle becomes blurry. Many of these machines are essentially electric motorcycles disguised as bicycles, and their top speeds can embarrass traditional petrol bikes.

Below we reveal the five fastest, most capable production models on the market today – judged purely on speed.

🏆 Top 5 Fastest Production E‑Bikes (By Top Speed)

Important note: The “Legality / Use Case” column helps you understand the nature of each vehicle. It does not mean that using the vehicle in the described scenario exempts you from all legal obligations – always check your local laws.

1. HPC Revolution W – The Pure Speed Beast

It represents the absolute pinnacle of speed. If you want an e‑bike that breaks all conventions, the HPC Revolution series is a name you cannot ignore. The top‑tier Revolution W boasts a peak power of 10.5 kW and a claimed top speed of a staggering 80 mph – on par with many traditional 125cc mopeds. HPC achieves this through a powerful battery pack and an efficient thermal management system, ensuring stable output even under extreme conditions.

2. ONYX RCR (80V) – The Aggressive Urban Cruiser

Among e‑bikes that can exceed 60 mph, the ONYX RCR has gained huge attention in recent years. The new 80V version pushes the top speed to 65+ mph, with a peak power of 18 kW. Its 0‑30 mph time is just 1.7 seconds – the instant punch is unforgettable when riding through city streets. However, be aware that this bike’s weight and performance are far beyond ordinary e‑bikes; legally, in most places it must be registered as a motorcycle or moped.

3. Stealth B‑52R – The Agile Off‑Road Hunter

If the previous two are more street‑oriented, the Stealth B‑52R is a high‑performance all‑terrain representative. As the ultimate evolution of the B‑52, the B‑52R’s peak torque jumps from 150 Nm to 230 Nm, peak power reaches 8.5 kW, and top speed hits 95 km/h. Its iconic “Hex Box” 6‑speed transmission lets you pedal at high speeds, creating a unique man‑machine synergy. With 200 mm of rear suspension travel and powerful four‑piston hydraulic brakes, it is built to conquer rough off‑road environments.

4. Stark Varg (Supermoto) – The King That Breaks All Boundaries

The Stark Varg is strictly an electric motorcycle, but its unique form and outstanding performance make it a benchmark in any discussion of extreme two‑wheel speed. The Supermoto version has been GPS‑measured at over 103 mph, with peak power of about 80 horsepower – rivaling 450cc high‑performance dirt bikes. Combined with an ultra‑light 124.5 kg chassis, its power‑to‑weight ratio is terrifying, delivering acceleration that leaves petrol bike owners staring in disbelief.

5. ASKMY E500 – The Legal Commuter with a Race Mode

The Ristretto 512 is a special “dual‑personality” machine. In Street Legal Mode, it is a standard Class 3 e‑bike, topping out at 28 mph. But once you switch to its dedicated “Race Mode”, it unlocks full potential, unleashing 4.5 kW of peak power and pushing the speed to 40 mph. This means you can ride legally on public roads, then enter a track or private property and instantly unlock near‑furious performance with the push of a button.

Speed is one of the most visceral attractions of the electric two‑wheel world, but it is never the only metric. When chasing that adrenaline rush, what deserves even more attention is the sophisticated thermal management system, lightweight composite materials, robust chassis and suspension, and the matching braking performance. Whichever bike you choose, remember: Always obey traffic laws on public roads. Only push the limits in a safe, legal environment.
