People often ask about the fastest electric bike, but the answer depends on what type of bike you mean. The absolute fastest electric bike in the world is a record-setting one-off machine, not a model you can buy. For normal riders, there are fast off-road bikes, folding bikes, and street legal electric bikes, each with their own speed limits. This guide goes through them so you know what to expect in every category.
The World Top Speed Record Holder
The record for the fastest electric bike top speed belongs to the Voxan Wattman. In 2021, former MotoGP racer Max Biaggi rode this custom-built machine to 283.182 mph (455.737 km/h).
Although it technically has pedals, it’s designed and functions more like an electric motorcycle. It was built only to test limits, not for sale, so riders looking for the fastest electric bike available to buy will need to focus on production models instead.
Fastest Electric Bike 2025
When people ask what is the fastest electric bike you can buy, the answer depends on whether you mean off-road or street-legal. Some of the fastest electric bike for adults are closer to motorcycles in design and performance.
These bikes can hit extreme speeds, but many of them are not legal for public roads when unlocked or modified. Here are a few standouts:
Hi Power Cycles (HPC) Revolution W
Often listed as the world’s fastest electric bike that can be purchased, the HPC Revolution W can reach 80 mph (128 km/h). It is built for off-road use and dominates in raw speed, but it is not classified as a fastest street legal electric bike.
Stark Varg MX
The fastest electric dirt bike for motocross riders is widely considered to be the Stark Varg MX. This Swedish-made machine can hit 80 mph and produces 80 horsepower. It is designed for enduro and track use, making it the top choice for riders searching for the fastest electric dirt bike for adults.
Delfast Top 3.0i
The Delfast Top 3.0i is known for its mix of speed and endurance. In its off-road “unlimited mode,” it can reach 50 mph (80 km/h). It also has one of the longest ranges of any production e-bike, keeping it in the conversation for fastest electric bike 2025.
ENGWE X26
Among the fastest foldable electric bikes, the ENGWE X26 is both powerful and practical. It reaches about 25 km/h (15.5 mph) in its EU-legal mode, with fat tires and full suspension making it a fastest fat tire electric bike for adults. With fat tires and full suspension, it serves as a fastest fat tire electric bike for adults who want speed and versatility in one package.
ENGWE Engine Pro 2.0
The ENGWE Engine Pro 2.0 is an all-terrain option with strong power and suspension. While not as fast as pure off-road machines, it offers a reliable speed of 25 km/h (PAS 5, EU legal mode) for commuting and trails. Its blend of range, suspension, and motor strength makes it one of the better-balanced picks in the fastest electric bike category.
Fastest Street-Legal Electric Bikes
Most riders who use an e-bike for commuting or casual rides must follow local road rules. In many regions, the fastest legal option is a Class 3 e-bike, which provides pedal assist up to 28 mph (45 km/h).
These bikes often have motors capable of more power, but they are capped by the controller to stay legal on public roads. A good example is the Macfox commuter e-bike, which sits right at this limit.
ENGWE L20 Step-Thru
The ENGWE L20 Step-Thru is a legal and fastest electric pedal bike for riders who want comfort with steady speed. It offers a pedal-assist range of up to 140 km at 25 km/h. Wide 20x4.0 inch fat tires keep the bike stable on both city roads and light trails, while the step-through frame makes it easier to get on and off.
Riders can also choose from multiple colors, Flamingo Pink, Avocado Green, Snow White, and Onyx Black, for a mix of style and everyday performance.
Fastest Electric Mountain Bike
Not every e-bike is made for smooth pavement. Some are designed for riders who want speed and control on steep trails and rough ground. These bikes have stronger motors, long-lasting batteries, and suspension systems to handle bumps and jumps.
Hi Power Cycles (HPC) Revolution X9
The HPC Revolution X9 is one of the fastest mountain-ready e-bikes ever built. It can reach speeds of 65+ mph, which puts it closer to a motocross machine than a regular bike. It’s meant for advanced riders and off-road use only, not public streets.
ENGWE M20
