Best 40 MPH Electric Bikes for Adults in 2026: 5 Compared

Most electric bikes are designed around 20–28 mph speeds. But if you want stronger acceleration, higher cruising speeds, and a more motorcycle-inspired riding position, a 40 mph electric bike for adults is a very different category.

The challenge is that not every eBike advertised as “high performance” can actually reach 40 mph. Motor output, battery voltage, rider weight, terrain, braking, and the bike's speed settings all matter.

For this guide, we compared five high-performance electric bikes that can reach or exceed 40 mph in their unrestricted or designated high-speed modes.

Important: Several models below are designed for off-road, private-property, or race-track use when operating at their highest speeds. Always check local laws before riding.

Best Electric Bike for Adults 40 MPH in 2026

TakeMov G35H — Best Long-Range Value

Best for: Adults who want 40 mph performance, high torque, and a very large battery without spending several thousand dollars.

The TakeMov G35H is the strongest value-oriented option in this comparison. Its $1,144 price combines a 40 mph top-speed rating with a 1000W rated motor, 2000W peak output, 100 Nm of torque, and a 48V 50Ah dual battery.

The biggest advantage is the battery. 2,400Wh is a large amount of battery capacity for a moped-style eBike, giving the G35H a useful advantage for long-distance riders.

Its claimed PAS range is up to 160 miles, but that figure should not be interpreted as a 160-mile range at 40 mph. Actual range will vary significantly with speed, rider weight, terrain, wind, temperature, and riding mode.

The trade-off is weight. At 107 lbs, the G35H is not a lightweight commuter and may be difficult to carry upstairs or load into a vehicle.

Bottom line: If your priorities are speed, battery capacity, torque, and value, the G35H is one of the strongest options in this group.

ONYX RCR 80V — Best High-Speed Performance

The ONYX RCR 80V sits in a different performance class from most high-speed eBikes. ONYX lists a 65–75 mph off-road top speed, up to 18kW peak power, and an 80V nominal battery with 3,600Wh of capacity.

The RCR 80V can accelerate from 0–30 mph in a claimed 1.7 seconds. It also offers eight speed modes and different throttle tunes, allowing riders to choose between range-focused and performance-focused settings.

Its battery provides substantial capacity, with ONYX listing up to 140 miles in its lowest-speed Cruise Eco setting. At higher speeds, the range drops considerably; the manufacturer lists approximately 80 miles at a 40 mph Cruise Hyper setting and 30 miles at a 75 mph Thrill Hyper setting.

The RCR 80V is also substantially heavier than the G35H, at approximately 155 lbs ready to ride.

Bottom line: Choose the RCR 80V if 40 mph is only the starting point and maximum performance is your priority.

Motor Goat V3 — Best for Torque and Acceleration

Best for: Riders who want strong acceleration, high torque, and a more compact moped-style platform.

The Motor Goat V3 is one of the better-known high-performance options in this category. Goat Power Bikes lists it at $2,999, with a 60V 25Ah battery and up to 56 miles of pedal-assist range or 37 miles in all-electric mode.

The Motor Goat V3 uses a 2,000W rated motor with 3,000W peak output and produces a claimed 170 Nm of torque. Goat Power Bikes lists its top speed at 40–50+ mph, depending on conditions.

Its reinforced aluminum frame, full suspension, 4-piston hydraulic brakes, and 4-inch front / 4.5-inch rear tires are designed around high-performance riding.

One important detail: Goat Power Bikes states that the Motor Goat V3 ships from the factory configured with a 20 mph speed limit, and additional operating modes are subject to applicable laws.

Bottom line: Choose the Motor Goat V3 if acceleration and torque matter more than purchase price.

Ariel Rider X-Class 60V PPB — Best Moped-Style Performance

Best for: Riders who want a motorcycle-inspired design with 40+ mph off-road performance.

The Ariel Rider X-Class 60V PPB is specifically positioned as a private-property and off-road model. Ariel Rider lists a 1500W motor with 2700W peak output, 132 Nm of torque, and a 40+ mph off-road top speed.

Its dual 60V 35Ah battery configuration provides a large amount of battery capacity, while the company lists an estimated range of 85–105 miles.

The chassis uses 4-piston hydraulic brakes with 203mm rotors, a 100mm-travel inverted front fork, and an 80mm rear shock. It also uses wide 20 x 4.5-inch front and 20 x 5.0-inch rear tires.

At 116 lbs, it is heavy, but that is consistent with its large battery, suspension, and high-performance equipment.

Ariel Rider currently lists the X-Class 60V PPB at a sale price of $2,499, with a regular price of $3,099.

Bottom line: Choose the X-Class 60V PPB if moped styling, torque, suspension, and off-road performance are your priorities.

Ristretto 512 A20 — Best Premium 40 MPH Option

Best for: Riders who want premium construction, handling-focused design, and a 40 mph performance mode.

The Ristretto 512 A20 takes a different approach from the larger moped-style bikes in this comparison.

Ristretto lists the 512 A20 at $3,780, reduced from $4,200. Its compact 20-inch wheel configuration is designed around the company's handling-focused platform.

The bike uses a mid-drive motor capable of up to 4,500W peak power. In Street Legal Mode, it reaches 28 mph, while Race Mode can reach 40 mph. Ristretto specifically states that Race Mode is intended for private property and race tracks.

The 512 uses a 30Ah Catalina battery with 1,550Wh of capacity. Ristretto claims up to 100 miles of pedal-assist range and more than 45 miles in throttle-only mode.

The bike also includes a 3.5-inch color TFT display, app connectivity, customizable power modes, and an integrated battery tracking slot designed for an Apple AirTag.

Bottom line: Choose the Ristretto 512 A20 if premium design, handling, technology, and a 40 mph private-property mode matter most.

Which 40 MPH Electric Bike Is Best for You?

If You Want...	Choose
Best long-range value	TakeMov G35H
Maximum speed	ONYX RCR 80V
Strongest acceleration & torque	Motor Goat V3
Moped-style performance	Ariel Rider X-Class 60V PPB
Premium 40 mph option	Ristretto 512 A20

The important point is that “best” depends on how you ride.

A 65+ mph electric motorbike isn't automatically a better choice than a 40 mph eBike. If your priorities are price, range, comfort, or everyday usability, the G35H may make more sense than a much faster machine.

TakeMov G35H vs Other 40 MPH Electric Bikes

G35H vs ONYX RCR 80V

The ONYX is in a substantially higher performance class, with a 65–75 mph off-road top speed and up to 18kW peak power. The G35H is much more affordable and offers a 2,400Wh battery.

G35H vs Motor Goat V3

The Motor Goat offers more claimed torque and a higher potential top speed. The G35H is considerably cheaper and has a much larger 2,400Wh battery compared with the Motor Goat's 1,500Wh battery.

G35H vs Ariel Rider X-Class 60V

The X-Class 60V PPB has 132 Nm of torque, 40+ mph off-road capability, and a dual 60V 35Ah battery setup. The G35H is cheaper and lighter, while the X-Class offers more aggressive suspension and braking hardware.

G35H vs Ristretto 512 A20

The Ristretto focuses more on premium engineering and handling, with a 4,500W peak mid-drive motor and 40 mph Race Mode. The G35H focuses more on battery capacity and value.

How Fast Is 40 MPH on an Electric Bike?

For context:

Speed	Typical Use
20 mph	Standard eBike
28 mph	Class 3 eBike
30–35 mph	High-speed moped eBike
40 mph	High-performance eBike
45–50+ mph	Extreme-performance category
65+ mph	Electric motorbike territory

A 40 mph electric bike is therefore well beyond the speed of a typical commuter eBike.

That's why components such as brakes, suspension, tires, frame design, and rider experience become increasingly important.

Can an Electric Bike Really Go 40 MPH?

Yes. High-performance electric bikes can reach 40 mph or more, but actual speed depends on motor output, battery voltage, rider weight, terrain, wind, battery charge, and configuration.

The Motor Goat V3 is listed at 40–50+ mph, while the Ariel Rider X-Class 60V PPB is rated at 40+ mph off-road. The Ristretto 512 A20 can reach 40 mph in Race Mode, and the ONYX RCR 80V goes substantially beyond 40 mph.

Don't treat a manufacturer's top-speed number as a guarantee that every rider will reach that speed.

What to Look for in a 40 MPH Electric Bike

Motor and Torque

Look at rated power, peak power, torque, controller output, and battery voltage rather than one wattage number.

For example, the Motor Goat V3 has a claimed 170 Nm of torque, while the Ariel Rider X-Class 60V PPB lists 132 Nm.

Battery

For high-speed riding, battery capacity matters. Compare Wh, not just Ah.

For example:

48V × 50Ah = 2,400Wh

That's one of the G35H's strongest specifications.

Brakes

Hydraulic disc brakes are preferable for a high-speed setup. Larger rotors and multi-piston calipers can also provide additional braking capability.

The Motor Goat V3 and X-Class 60V PPB both use 4-piston hydraulic brakes with 203mm rotors.

Suspension

Full suspension can improve comfort and control over rough surfaces, particularly when combined with appropriate tires.

Weight

High-performance moped eBikes tend to be heavy. The G35H weighs 107 lbs, the X-Class 116 lbs, and the ONYX RCR 80V approximately 155 lbs ready to ride.

Long-Range 40 MPH Electric Bikes

Battery capacity becomes especially important when speed is a priority.

The TakeMov G35H uses a 48V 50Ah dual battery with 2,400Wh of total energy, giving it one of the largest battery systems in this comparison.

The ONYX RCR 80V goes even further with a 3,600Wh battery, although its higher power output and higher-speed riding can consume energy much faster. ONYX lists 80 miles at a 40 mph Cruise Hyper setting and 30 miles at a 75 mph Thrill Hyper setting.

The Motor Goat V3's 1,500Wh battery is smaller but still provides up to 56 miles of claimed pedal-assist range.

Range claims need context.

The G35H's up to 160-mile PAS range is not a guaranteed 40 mph range. Higher speeds, heavier riders, hills, frequent acceleration, and throttle-only riding can substantially reduce range.

For long-distance riding, battery capacity is therefore more useful than looking at a single advertised mileage number.

40 MPH Electric Bikes Under $1,500

Finding a 40 mph electric bike for adults under $1,500 significantly narrows the market.

At $1,144, the TakeMov G35H stands out by combining:

Up to 40 mph
100 Nm torque
2000W peak power
2,400Wh dual battery
Hydraulic brakes
Full suspension
330 lb maximum load

The trade-off is its 107 lb weight and 10–12 hour charging time.

For riders who prioritize speed, range, and equipment over portability, that is a reasonable compromise.

Are 40 MPH Electric Bikes Legal?

It depends on your state and local regulations.

A 40 mph eBike generally exceeds the speed limits associated with standard Class 1, Class 2, and Class 3 eBike classifications. Some high-performance bikes may therefore be treated differently when operated at unrestricted speeds.

The models in this comparison also have different operating restrictions.

For example, Ariel Rider explicitly identifies the X-Class 60V PPB as a private-property and off-road model, while its 40+ mph mode is designated for off-road use.

Ristretto states that its 40 mph Race Mode is intended for private property and race tracks.

ONYX lists its 65–75 mph top speed as off-road.

Goat Power Bikes also notes that the Motor Goat V3 may not qualify as an e-bike in every jurisdiction.

Rules can depend on:

Motor power
Maximum speed
Throttle operation
Pedal capability
Where the bike is ridden
State and local classification

Always check local regulations before riding at unrestricted speeds.

40 MPH Electric Bike vs Electric Dirt Bike

40 MPH eBike	Electric Dirt Bike
Pedals	Usually not bicycle-focused
Commuting	Better
Off-road	Moderate to strong
Riding position	Upright or moped-style
Practicality	Higher
Performance focus	Moderate to extreme

If you want pedals, commuting flexibility, and moped-style comfort, an eBike makes more sense.

If your priority is aggressive off-road riding, an electric dirt bike may be the better category.

Who Should Buy a 40 MPH Electric Bike?

A 40 mph eBike makes the most sense for adults who:

Want more speed than a standard 20–28 mph eBike
Need strong acceleration
Ride longer distances
Prefer a moped-style riding position
Want higher motor performance
Have suitable private-property or legal riding areas

It may not be the right choice if you:

Need a lightweight commuter
Frequently carry your bike upstairs
Mostly ride at 15–20 mph
Have limited storage
Need a standard Class 1, 2, or 3 eBike
