9 Fastest Electric Bikes: Speed and Performance
1. E Ride Pro SR — Fastest Overall
The E Ride Pro SR leads this comparison with a claimed maximum speed of 70 mph. Its motor produces 10kW of rated power and up to 25kW at peak output, supported by a 72V 50Ah battery with 3,600Wh of stored energy.
Acceleration is one of its greatest strengths. The manufacturer claims the SR can reach 30 mph in just 1.8 seconds, with peak wheel torque of 630Nm. Despite its powerful motor, the bike weighs approximately 83kg, making it relatively compact for its performance level.
The SR also features adjustable FastAce suspension, hydraulic disc brakes and a motorcycle-style riding position. Its claimed range exceeds 62 miles when travelling at 25 mph, although higher speeds will increase energy consumption.
For riders prioritising outright acceleration and top speed, the E Ride Pro SR offers the strongest overall performance in this comparison. It is designed as an electric dirt bike rather than a conventional pedal equipped bicycle.
2. Sur-Ron Storm Bee — Best Full Size Electric Dirt Bike
The Sur-Ron Storm Bee reaches a claimed top speed of 68.3 mph, placing it just behind the E Ride Pro SR. Its mid drive motor delivers up to 22.5kW of peak power, while the 104V 55Ah removable battery provides a claimed range of up to 74.5 miles at approximately 31 mph.
The Storm Bee is larger than many lightweight electric dirt bikes, with a 21-inch front wheel, an 18-inch rear wheel and a 56.2-inch wheelbase. This gives it a stable platform for demanding off road riding.
Its adjustable long travel suspension absorbs impacts on rough terrain, while the high performance braking system helps riders manage speed during descents and technical sections.
Compared with the E Ride Pro SR, the Storm Bee places greater emphasis on full size motocross ergonomics and high speed stability. It suits riders who prefer a larger chassis and a more traditional motorcycle riding position.
3. Talaria Komodo — Most Powerful Electric Bike
The Talaria Komodo has the highest advertised peak power in this comparison, producing up to 32kW. Despite this advantage, its claimed top speed is approximately 65.2 mph, slightly below the E Ride Pro SR and Sur-Ron Storm Bee.
Its 97.2V 45Ah battery stores approximately 4,374Wh of energy, with a claimed range of up to 70 miles. Talaria also advertises up to 754Nm of rear wheel torque and acceleration from 0 to 60 mph in 4.5 seconds.
The Komodo uses a forged aluminium frame, adjustable suspension and 21-inch front and 18-inch rear wheels. Its design focuses on demanding terrain, rapid acceleration and powerful climbing performance.
The Komodo demonstrates that the most powerful electric bike is not always the fastest. Motor gearing, controller settings, wheel size and aerodynamic resistance can all influence maximum speed.
For riders who value acceleration and torque more than achieving the highest possible mph figure, the Komodo is a strong contender.
4. Stealth B-52R — Fastest Electric Bike With Pedals
The Stealth B-52R combines a working pedal system with a high power electric motor. It has a claimed maximum speed of approximately 59 mph, making it the fastest pedal equipped model in this comparison.
Its direct drive rear hub motor produces up to 8,500W and 230Nm of torque. A 3,600Wh battery provides a claimed range of approximately 31 to 75 miles, depending on the riding mode and conditions.
Unlike conventional electric dirt bikes, the B-52R includes a six speed pedal transmission, allowing riders to contribute pedal power alongside the motor.
The bike also features 180mm of front suspension travel, 200mm at the rear and four piston brakes with large 250mm rotors.
The B-52R appeals to riders who want motorcycle-like electric performance while retaining the ability to pedal. Its combination of speed, suspension and strong braking makes it particularly suited to demanding off road terrain.
5. Stealth B-52 Bomber — Classic High Speed Electric Bike
The Stealth B-52 Bomber helped establish the market for high power pedal equipped electric bikes.
Specialist retailer specifications for the original model list a maximum speed of approximately 50 mph and motor output of up to 6,200W. Some versions also advertise a maximum range of around 62 miles.
Its distinctive monocoque frame houses the battery and electrical components, while the pedal gearbox allows the rider to contribute additional power.
The B-52 Bomber uses long travel suspension and a robust frame designed to withstand the demands of high power riding. However, its relatively heavy construction makes it less agile than a lightweight electric mountain bike.
Although newer models such as the B-52R offer greater peak power, the original Bomber remains a notable example of the 50 mph electric bike category.
Buyers comparing older or second hand models should check the exact battery and motor configuration, as specifications can vary between generations.
6. Stealth F-37 — Lighter High Speed Performance
The Stealth F-37 provides a balance between acceleration, top speed and handling.
Its motor produces up to 3,700W and 120Nm of torque, delivering a claimed maximum speed of approximately 43.5 mph. The 1,500Wh battery supports a claimed range of around 19 to 50 miles.
Compared with the B-52 models, the F-37 uses a smaller battery and a lighter design. This makes it more responsive when changing direction or navigating tight trails.
The bike features hydraulic braking with 250mm rotors and regenerative braking technology, which can recover some energy during deceleration.
While the F-37 cannot match the top speed or battery capacity of the B-52R, it offers a different riding experience. Riders looking for a more agile high performance electric bike may find its lower weight and smaller frame more appealing.
7. TESWAY X9 Ultra — Best Dual Motor Electric Bike for Speed
The TESWAY X9 Ultra combines a claimed top speed of 43 mph with a powerful dual motor system and bicycle-style features.
Its two motors deliver a combined peak output of 4,000W and up to 240Nm of torque. The dual motor configuration provides strong acceleration and improved traction on loose or uneven terrain.
The X9 Ultra uses a 60V 30Ah battery with 1,800Wh of stored energy. According to TESWAY's specifications, its claimed range varies depending on the motor mode:
- Single motor mode: 70–120 miles
- Dual motor mode: 50–70 miles
Switching to dual motor mode provides more available drive power, while single motor operation can help conserve battery energy over longer distances.
The bike also features full suspension, 26 × 4.0-inch fat tyres, Shimano seven speed gears and four piston hydraulic brakes.
Its 43 mph advertised maximum places it among the faster pedal equipped electric bikes in this comparison, although it remains below the Stealth B-52R.
For buyers exploring this performance category, the relationship between motor output and maximum speed is covered further in our article on whether an electric bike can reach 40 mph.
The X9 Ultra stands out for combining dual motor acceleration, a high voltage battery and a mountain bike-inspired design.
8. TESWAY X7 AWD — Best for Speed and Long Range
The TESWAY X7 AWD takes a different approach to high speed performance.
With a claimed maximum speed of approximately 38 mph, it is slower than the X9 Ultra. However, its main advantage is a substantially larger battery.
The X7 AWD features dual motors producing up to 3,600W of combined peak power and approximately 200Nm of torque. Its all wheel drive configuration distributes power between the front and rear wheels, helping maintain traction on challenging surfaces.
Its 52V 60Ah battery stores 3,120Wh of energy. TESWAY advertises a maximum pedal assist range of up to 200 miles and a pure electric range of up to 180 miles under favourable conditions.
The bike also includes full suspension, 20 × 4.0-inch fat tyres, four piston hydraulic brakes and a step through frame.
Compared with the X9 Ultra, the X7 AWD prioritises battery capacity, comfort and longer distance riding over maximum speed.
This distinction matters because a higher top speed does not necessarily produce a better overall riding experience. Battery capacity and how frequently the motors operate at high power can make a substantial difference to usable range.
The X7 AWD is particularly relevant for riders who want strong acceleration and a large battery for extended journeys.
9. DUOTTS F26 — More Accessible 30 MPH Electric Bike
The international version of the DUOTTS F26 offers a claimed top speed of approximately 31 mph, making it an entry point into the high speed dual motor electric bike category.
Its two 750W hub motors provide a combined nominal output of 1,500W. The 48V 20Ah battery stores 960Wh of energy, with a claimed pedal assist range of up to 120km.
The F26 features 26 × 4.0-inch fat tyres, an 80mm suspension fork and hydraulic disc brakes with 160mm rotors.
Unlike the full suspension models above, the F26 has a simpler frame and suspension design. This helps reduce complexity and cost, although it offers less comfort over rough terrain.
Its international version is advertised with a 50km/h maximum speed, while other market versions have different motor and speed specifications.
For buyers looking at 30 mph electric bikes rather than 50 mph or 70 mph performance machines, the F26 provides an alternative with a more conventional bicycle layout.
30 MPH vs 50 MPH Electric Bikes: What's the Difference?
A 30 mph electric bike already offers considerable speed compared with an ordinary pedal assist bicycle. Moving into the 50 mph category, however, changes the demands placed on the motor, battery and other components.
The difference is not simply an extra 20 mph. Travelling faster requires substantially more power to overcome aerodynamic drag, particularly as speed increases.
| Feature | 30 MPH Electric Bike | 50 MPH Electric Bike |
|---|---|---|
| Example | DUOTTS F26 International Version | Stealth B-52 Bomber |
| Top Speed | Around 30 mph | Around 50 mph |
| Motor Performance | Moderate high power output | Greater power demand at top speed |
| Acceleration | Depends on motor torque and controller | Often stronger on high performance models |
| Battery Consumption | Lower at a steady 30 mph, all else equal | Significantly higher at a steady 50 mph |
| Typical Focus | General high speed performance | More demanding high speed riding |
At higher speeds, aerodynamic drag becomes increasingly important. On level ground, the power needed to overcome air resistance increases approximately with the cube of speed.
For example, travelling at 50 mph requires about 4.6 times the aerodynamic power needed at 30 mph, assuming the same riding position and aerodynamic characteristics.
This does not mean total battery consumption will always increase by exactly that amount, but it explains why the fastest electric bikes can drain their batteries quickly when ridden at sustained high speeds.
A 30 mph model may therefore offer a more practical balance of speed and endurance for some riders, while a 50 mph electric bike prioritises a higher performance ceiling.
What Makes an Electric Bike Faster?
The fastest electric bikes combine powerful motors, suitable battery voltage, high output controllers and components designed to handle increased speed.
However, each factor affects performance differently.
Motor Power and Torque
Motor power is an important part of high speed performance, but wattage alone does not determine maximum speed.
Higher power output can improve acceleration, climbing ability and the bike's capacity to maintain speed against resistance.
Torque is particularly important when starting from a standstill or climbing steep hills, while motor power becomes more important as speed builds. Understanding the difference between torque and power helps explain why stronger acceleration does not always mean a higher top speed.
For example, a powerful dual motor electric bike may accelerate more quickly than a single motor model without necessarily having a higher top speed.
The differences between single and dual motor electric bikes show how motor configuration affects traction, acceleration and energy consumption.
For a closer look at power ratings, our guide to 2000W electric bike speed explains why two motors with similar advertised wattage can produce different results.
Battery Voltage and Controller Output
Battery voltage influences how the motor and controller deliver power.
Higher voltage can support greater motor speed when the controller and motor design are compatible. This is one reason many high performance electric bikes use 60V, 72V or even higher voltage systems.
However, increasing voltage alone does not guarantee a faster bike.
The controller determines how much electrical current reaches the motor and can limit both acceleration and maximum speed.
For example, a well designed 60V system may outperform a poorly matched 72V system, even when the higher voltage configuration appears more powerful on paper.
The relationship between 52V and 60V electric bike systems illustrates why motor compatibility and controller output matter alongside battery voltage.
Motor Design and Gearing
Motor design also affects how efficiently electrical energy becomes forward motion.
Mid drive systems transfer power through a chain or gearbox, while hub motors drive the wheel directly.
Gearing can help a motor operate within an effective speed range, allowing manufacturers to prioritise acceleration, climbing ability or maximum speed.
This helps explain why two electric bikes with similar peak power ratings can reach different top speeds.
Rider Weight, Tyres and Terrain
The weight of the bike, rider and any additional cargo affects acceleration and climbing performance.
Tyres also influence rolling resistance. Wide fat tyres provide traction on loose surfaces, but may require more energy to maintain speed than narrower tyres with lower rolling resistance.
Terrain and wind are equally important. Steep climbs, soft ground and strong headwinds increase motor demand.
As a result, an electric bike's real world top speed may differ from its advertised figure, even when the motor and battery specifications are unchanged.
Does a Bigger Battery Make an Electric Bike Faster?
Not necessarily. A larger battery usually increases the amount of stored energy available for riding, rather than directly increasing maximum speed.
Battery capacity is commonly measured in watt hours (Wh), calculated by multiplying battery voltage by amp hours:
Battery Capacity (Wh) = Voltage (V) × Amp Hours (Ah)
For example, the TESWAY X9 Ultra and X7 AWD use different battery configurations:
| Model | Battery | Capacity | Claimed Top Speed |
|---|---|---|---|
| TESWAY X9 Ultra | 60V 30Ah | 1,800Wh | 43 mph |
| TESWAY X7 AWD | 52V 60Ah | 3,120Wh | 38 mph |
The X7 AWD's 60Ah battery stores approximately 73% more energy than the X9 Ultra's 30Ah battery, yet the X9 Ultra has the higher advertised top speed. This shows why battery capacity and maximum speed should be evaluated separately.
This difference reflects their motor systems, voltage, controller settings and overall design.
The X9 Ultra focuses on higher speed performance, while the X7 AWD combines strong motor output with substantially more battery capacity.
A larger battery can also help sustain demanding riding for longer, provided the battery and electrical system can deliver the required power. But battery capacity alone does not determine how fast a bike can travel.
At sustained high speeds, energy use rises considerably. Therefore, claimed maximum ranges should not be interpreted as the distance a bike can travel while continuously operating at its top speed.
