Fastest Electric Bikes Available in the UK

The E Ride Pro SR is the fastest model in this guide, with a claimed top speed of 70 mph. The Sur-Ron Storm Bee and Talaria Komodo are close behind. Pedal-equipped models such as the Stealth B-52R and Tesway X9 Ultra are slower, but they offer a different mix of speed, range and bicycle-style control.

1. E Ride Pro SR — Fastest Overall

The E Ride Pro SR has a claimed top speed of 70 mph, making it the fastest bike in this guide. Its motor produces 10kW of rated power and up to 25kW at peak output. The 72V 50Ah battery supports a claimed range of at least 62 miles at 25 mph.

The SR also reaches 30 mph in a claimed 1.8 seconds. This quick acceleration comes from its strong motor, 630Nm of peak wheel torque and low weight for its performance level. It weighs about 83kg and uses adjustable FastAce suspension at both ends. The front and rear 220mm brake rotors help control its speed.

The SR is built for riders who place acceleration and high-speed performance above bicycle-style features. Its compact frame makes it smaller than a full-size electric motocross bike, but its power output is much closer to one. The adjustable suspension also allows riders to change the setup for jumps, loose trails or harder ground.

2. Sur-Ron Storm Bee — Best Full-Size High Speed E-Bike

The Sur-Ron Storm Bee has a claimed top speed of 68.3 mph. It uses a 22.5kW mid-drive motor and a high-voltage battery system. The current UK specification lists a 104V 55Ah removable battery and a claimed range of up to 74.5 miles when travelling at 31 mph.

The Storm Bee is larger than many lightweight electric dirt bikes. It has a 21-inch front wheel, an 18-inch rear wheel and a 56.2-inch wheelbase. This gives it a stable feel at higher speeds. Its adjustable long-travel suspension is designed to handle rough ground and large impacts. The bike also uses a liquid-cooled motor control unit to manage heat during hard riding.

Its full-size frame gives the rider more space and a riding position closer to a traditional motocross bike. This makes it better suited to open trails and higher-speed terrain than tight, slow routes. The larger chassis also feels more planted when braking or landing after a jump.

3. Talaria Komodo — Most Powerful

E-Bike

The Talaria Komodo has the highest peak power figure in this list. Its motor can produce up to 32kW, while the claimed top speed is 105km/h, or about 65.2 mph. Talaria also lists up to 754Nm of torque and a 0–60 mph time of 4.5 seconds.

The 97.2V 45Ah battery offers a claimed range of up to 70 miles. The Komodo uses a forged alloy frame, inverted front forks and a rear single shock. Its 21-inch front and 18-inch rear wheels suit loose ground and rough trails. Hydraulic disc brakes are fitted at both ends. The high voltage and strong controller output help the motor maintain power as the bike reaches higher speeds.

The Komodo focuses more on strong acceleration than taking the top position for maximum speed. Its high torque should help it respond quickly when climbing or leaving slow corners. The balanced wheel setup also gives the front tyre better control while the wider rear tyre handles the motor output.

4. Stealth B-52R — Fastest Pedal-Equipped

E-Bike

The Stealth B-52R combines electric power with a working pedal system. It has a claimed top speed of 95km/h, or about 59 mph. Its direct-drive hub motor produces up to 8,500W and 230Nm of torque.

The bike uses a six-speed sealed transmission. This allows the rider to continue pedalling at speeds where a normal bicycle gear system would become difficult to use. Its 3,600Wh battery provides a claimed range of 50 to 120km, depending on the riding mode and conditions.

The B-52R has 180mm of front suspension travel and 200mm at the rear. It also uses four-piston brake callipers with large 250mm rotors. These parts give the bike more control over rough ground and during hard braking.

Unlike most machines near this speed, the B-52R keeps pedals as a useful part of the design. The rider can add pedal power, change gears and ride it more like a heavy downhill bike. Its hub motor also reduces the number of moving parts in the main drive system.

5. Stealth B-52 Bomber — Premium High Speed E-Bike

The original Stealth B-52 Bomber helped define the high-power pedal electric bike. A UK specialist retailer lists a top speed of 50 mph, a 6,200W motor and a claimed maximum range of 62 miles. The listed bike weighs about 64kg and supports a maximum load of 120kg.

The B-52 uses a strong monocoque frame with long-travel suspension. It also has a pedal gearbox, which separates it from electric dirt bikes that rely only on a throttle. Its heavy frame and large battery make it less agile than a light mountain bike, but they help support the motor, suspension and braking parts needed for higher speeds.

Its enclosed frame protects much of the battery and electrical system from dirt and impact. The weight is noticeable at low speed, but the long wheelbase and suspension help it feel stable once the pace increases. It remains a strong option for riders who prefer the original Stealth design.

6. Stealth F-37 — Lighter Stealth Performance

The Stealth F-37 is lighter and less powerful than the B-52R, but it still reaches a claimed 70km/h, or about 43.5 mph. Its motor produces up to 3,700W and 120Nm of peak torque. The battery has a capacity of 1,500Wh and provides a claimed range of 30 to 80km.

Large 250mm brake rotors give the F-37 strong braking force. Regenerative braking also helps slow the rear wheel while returning a small amount of energy to the battery. Compared with the B-52 models, the F-37 is designed to feel more agile. It is easier to move through tight trails while still offering far more speed than a normal electric mountain bike.

The lower weight also makes direction changes easier and reduces the effort needed to control the bike at slower speeds. Its smaller battery limits the range compared with the B-52R, but it creates a better balance for riders who value handling over maximum distance.

7. Tesway X9 Ultra — Best Value Fast E-Bike

The Tesway X9 Ultra is built to reach the 40 mph range, with a claimed maximum speed of 43 mph. It uses two motors with a combined peak output of 4,000W. Each motor can produce up to 120Nm, giving the bike a combined maximum torque figure of 240Nm.

Its 60V 30Ah battery stores 1,800Wh of energy. Tesway claims a pedal-assist range of up to 120 miles and a pure electric range of up to 100 miles under suitable conditions. The bike also has full suspension, 26 × 4.0-inch Kenda fat tyres and four-piston hydraulic brakes with 180mm rotors.

The Tesway X9 Ultra is not as fast as the high-powered dirt bikes above it. However, it combines a 43 mph claimed speed with pedals, Shimano gears, a large saddle and a more accessible price. Its dual motors also provide better drive on hills and loose ground. The riding position is more relaxed than the narrow seats found on electric dirt bikes, which may suit longer trips.

8. Tesway X7 AWD — Best for Speed and Long Range

The Tesway X7 AWD has a claimed top speed of about 38 mph. Its dual-motor system produces up to 3,600W of peak power and around 200Nm of torque. Power is sent to both wheels, giving the bike stronger dual motor traction on loose or uneven surfaces.

Its main strength is battery capacity. The 52V 60Ah battery stores 3,120Wh. Tesway claims up to 200 miles of pedal-assist range and up to 180 miles in pure electric mode under ideal test conditions.

The Tesway X7 X7 AWD uses 20 × 4.0-inch tyres, front and rear suspension and four-piston hydraulic brakes with 203mm rotors. It weighs about 54kg. The large battery adds weight, but it gives the bike far more stored energy than many faster models.

Its smaller wheels help the bike produce strong pull from a stop, while the step-through frame makes getting on easier. The wide saddle and upright position also make it more focused on long rides, mixed terrain and carrying loads than on maximum speed alone.

9. DUOTTS F26 — Lower Cost Dual Motor E-Bike

The international version of the DUOTTS F26 has a claimed top speed of 50km/h, or about 31 mph. It uses two 750W hub motors. Each motor produces up to 65Nm of torque, giving the bike strong pull on hills and loose ground.

The F26 has a 48V 20Ah Samsung-cell battery. Its claimed pedal-assist range is 100 to 120km, while pure electric range is listed at about 40 to 60km. It weighs 40kg and uses 26 × 4.0-inch Kenda fat tyres.

The bike has an 80mm suspension fork but no rear shock. Hydraulic disc brakes with 160mm rotors control its speed. It is the slowest model in this guide, but it offers dual-motor power at a much lower price than the other options.

Its 26-inch wheels provide a more traditional bike feel than the compact Tesway X7 AWD. The lack of rear suspension makes it less comfortable on rough ground, but the simpler design keeps the price and weight below many full-suspension dual-motor models.

What Determines the Top Speed of an Electric Bike?

The top speed of an electric bike depends on more than motor power. The battery, controller, weight and riding conditions also affect how fast it can go.

Motor Power

A stronger motor improves acceleration and helps the bike hold speed on hills. However, 2000W e-bike performance shows that high wattage alone does not always produce a higher top speed.

Battery Voltage and Controller

The differences between 52V and 60V show how higher voltage can help a motor turn faster. The controller then decides how much power reaches the motor. Both parts must work together to produce strong speed.

Battery Size

A larger battery usually improves range, not top speed. Battery capacity shows how much energy the bike can store, while voltage has a greater effect on speed.

Weight, Wheels and Tyres

A heavy bike takes longer to accelerate. Rider weight and cargo add more load. Wide tyres improve grip, but they also create more resistance than narrow tyres.

Terrain and Weather

Hills, headwinds and soft ground can reduce speed. A fully charged battery usually gives the best performance. Actual speed may therefore be lower than the figure listed by the brand.

The fastest electric bikes combine a strong motor, high battery voltage and a suitable controller. Weight, tyres and riding conditions then decide the final result.

Conclusion

The E Ride Pro SR is the fastest model in this guide, with a claimed top speed of 70 mph. The Storm Bee and Talaria Komodo follow closely, while the Stealth and Tesway models offer high speed with more bicycle-style features. Motor power matters, but voltage, controller output, motor design, weight, tyres and air resistance all help decide the final speed.
