Electric bikes offer a fun new way to ride and commute, but some ebike enthusiasts want more – straight up electrified speed! Let’s explore the technology behind high-speed ebikes.
What Makes an Ebike Fast?
Several key factors influence an electric bike’s top speed and acceleration:
- Motor Power – More watts equals more speed potential. Look for 1,000W+ motors.
- Voltage – Higher battery voltage like 60V or 72V allows higher velocity.
- Torque – Abundant torque provides rapid acceleration.
- Battery Capacity – Larger batteries deliver sustained high power.
- Gearing – More ratios optimize pedalling cadence at speed.
- Aerodynamics – A low, tucked riding stance reduces drag.
- Bike Weight – Lighter ebikes accelerate and climb easier.
DIY High Performance Ebikes
If production ebike options aren’t fast enough, building your own fastest electric bike lets you customize every detail. Common DIY upgrades include:
- Beefy motors like the Triton2 or Big E Formula producing 5+ horsepower.
- High voltage 60V, 72V or even 84V battery packs.
- Multi-speed internal gear hubs or wide-range cassettes.
- Race-inspired rigid forks and superlight frames.
- Hydraulic disc brakes with oversized rotors.
- Performance wheels and tires optimized for speed.
- Custom ergonomic handlebars allowing an aerodynamic riding position.
Let your imagination run wild building the ultimate street eating machine! Of course, use caution operating such a beast.
Ebike Speed Records
Ebike speed demons have set their sights on world records showing just how fast electric bikes can get:
- Sam Whittingham set an upright flying 200m record of 133 km/h (82.8 mph) in 2019.
- Denis Novitsky achieved a supine record of 147 km/h (91.3 mph) in 2021 by maximizing aerodynamics.
- Phil Roberts set a new 24-hour distance record in 2022 riding 740.85 miles on an ebike averaging over 30 mph!
While not legal or recommended for road use, these records demonstrate the incredible velocity ebikes are capable of in ideal conditions with professional riders.
Safety Considerations
When riding any ebike fast, it’s vital to take key precautions:
- Wear protective gear like helmets in case of falls at speed. Leathers help prevent road rash.
- Select models with front and rear suspension plus quality hydraulic disc brakes to maximize control.
- Practice emergency braking techniques in safe environments to develop skills.
- Understand speed wobble dynamics and how to control it if it occurs.
- Avoid excessive speed downhill where runaway ebikes can become unstoppable.
- Only attempt extreme speed runs on closed courses or deserted roads to avoid collisions.
- Set speed limits appropriate for conditions and your skill level to stay safe.
Going fast on an ebike can be a rush but respect the power these machines wield!
Are Fast Ebikes Street Legal?
In the United States, ebike regulations differ by state. Typically:
- 20 mph max assisted speed on public roads. Faster is only allowed on private property.
- 750W motor power limit (though not always enforced).
- No throttle-only propulsion allowed, pedalling must be required.
So most fast ebikes skirt the definition of street legal. Know your regional laws. Added risks of riding fast illegally include tickets and bike confiscation if caught. Ride responsibly.
In Europe, Speed Pedelecs capable of 45 kph are street legal on roads and require registration like motorcycles. Special licenses may also be mandated.
Key Takeaways on Fast Ebikes
In summary:
- Powerful motors, high voltage batteries, optimal gearing and lightweight frames enable faster ebikes.
- Models with hub motors or mid-drives can achieve speeds of 30 – 50+ mph.
- DIY builds allow customizing every component for maximum speed.
- Speed records demonstrate how specialized ebikes can hit over 90 mph.
- Safety gear and responsible riding is a must when riding any ebike at high speed.
- Local laws likely prohibit operation of fast ebikes in public areas.
If going fast to satisfy your need for speed appeals to you, applying this guide will help you discover the perfect high-performance electric bike options available today! Just be safe out there.
