1. Start with the Basics: Maintenance and Setup
You’d be surprised how much speed you can gain just by keeping your e-bike in top shape. A well-maintained bike runs smoother, uses energy more efficiently, and feels noticeably faster—even if the motor output hasn’t changed.
Keep Your Tires Properly Inflated
Underinflated tires create more rolling resistance, which means your motor has to work harder just to maintain speed. Check your tire pressure regularly—most e-bike tires recommend between 40 and 65 PSI, depending on the model. Use a quality bike pump with a gauge and inflate to the recommended level. You’ll feel the difference immediately: less drag, better acceleration, and a smoother ride.
Lubricate the Chain and Drivetrain
A dry, dirty chain wastes energy. Every time you pedal, friction slows you down. Clean your chain with a degreaser, wipe it dry, and apply a high-quality bike lubricant. Wipe off excess to avoid attracting dirt. A well-lubed drivetrain can improve efficiency by up to 10%, translating to faster speeds and longer battery life.
Check Brake Alignment
Sometimes brakes rub against the wheel even when not in use. This creates constant drag. Spin your wheels and listen for a rubbing sound. If you hear it, adjust the brake calipers so they only engage when you squeeze the lever. This small fix can make a big difference in how fast your bike feels.
2. Upgrade Your Tires for Speed
Tires are one of the easiest and most effective ways to make your e bike go faster. The right tires reduce rolling resistance, improve grip, and enhance overall performance.
Choose Low-Rolling-Resistance Tires
Look for tires labeled “LRR” or designed for speed and efficiency. Brands like Schwalbe, Continental, and Maxxis offer e-bike-specific models with slick or semi-slick tread patterns. These tires are built to minimize friction with the road, letting you coast farther and accelerate quicker.
For example, the Schwalbe Energizer Pro is a popular choice among speed-focused riders. It’s lightweight, puncture-resistant, and optimized for low rolling resistance. Swapping out chunky off-road tires for something sleeker can add 1–3 mph to your top speed.
Consider Tire Width
Narrower tires (like 1.75” or 2.0”) generally roll faster than wider ones because they have less surface area touching the ground. However, don’t go too narrow—you still need stability and comfort. A 2.0” tire is often the sweet spot for speed and control on paved roads.
3. Reduce Weight for Better Acceleration
Every pound counts when it comes to speed. A lighter bike requires less energy to move, which means faster acceleration and better hill-climbing ability.
Swap Heavy Components
Look for opportunities to shed weight. Replace steel fenders with lightweight aluminum or carbon versions. Swap a heavy rear rack for a minimalist one. Even your water bottle holder can make a difference—opt for a carbon fiber or plastic model instead of steel.
If you’re serious about speed, consider upgrading to a carbon fiber seatpost or handlebars. These can save 100–300 grams each, which adds up quickly.
Remove Unnecessary Accessories
Do you really need that giant front basket, phone mount, and extra lights? While convenient, bulky add-ons increase drag and weight. Strip down to the essentials: lights, a small lock, and maybe a compact bag. You’ll notice the bike feels more responsive and agile.
4. Optimize Your Motor and Battery Settings
Your e-bike’s motor and battery are the heart of its performance. With a few smart tweaks, you can unlock hidden speed.
Use the Highest Pedal-Assist Level
Most e-bikes have multiple assist levels (Eco, Tour, Sport, Turbo). To go faster, use the highest setting available. This delivers maximum power from the motor, helping you reach top speed quicker. Just be aware that higher assist drains the battery faster—so plan your rides accordingly.
Check for Firmware Updates
Some manufacturers release firmware updates that improve motor efficiency or unlock performance modes. Check your bike’s app or manufacturer website for updates. For example, Bosch and Shimano occasionally release updates that enhance torque delivery or top speed.
Upgrade Your Battery (If Compatible)
A higher-capacity battery (measured in watt-hours, or Wh) can provide more power and longer range. If your e-bike supports it, consider upgrading to a 500Wh or 625Wh battery instead of a 400Wh model. More power means stronger acceleration and sustained speed, especially on hills.
Note: Never use a battery with a higher voltage than recommended—this can damage your motor or controller.
5. Improve Aerodynamics
At higher speeds, air resistance becomes your biggest enemy. Even small changes in aerodynamics can make a noticeable difference.
Tuck Your Body Position
Lean forward, keep your elbows in, and lower your torso. This reduces your frontal area and cuts through the wind more efficiently. It’s the same principle professional cyclists use—less drag equals more speed.
Use Streamlined Accessories
Avoid boxy bags, wide phone mounts, or upright handlebars. Instead, choose sleek, low-profile gear. Aero handlebars or a drop-bar conversion (if compatible) can also help reduce wind resistance.
Wear Tight-Fitting Clothing
Baggy jackets and loose pants create drag. Opt for form-fitting cycling jerseys and shorts. Even a small reduction in wind resistance can help you maintain speed with less effort.
6. Consider Legal Speed Mods (With Caution)
Some riders explore “speed hacks” like reprogramming the controller or removing speed limiters. While technically possible, these modifications come with serious risks.
Understand the Risks
Tampering with your e-bike’s speed limiter may void your warranty, violate local laws, or cause mechanical failure. In many regions, e-bikes exceeding 20 or 28 mph are classified as mopeds or motorcycles—requiring registration, insurance, and a license.
Explore Legal Alternatives
Instead of hacking your bike, consider upgrading to a Class 3 e-bike if you need more speed. These models are designed for 28 mph and are street-legal in most areas. Brands like Rad Power Bikes, Specialized, and Trek offer high-performance models that deliver speed without the legal gray area.
Conclusion
Making your e bike go faster doesn’t require extreme modifications or risky hacks. With smart upgrades, regular maintenance, and a few strategic tweaks, you can boost your speed safely and legally. Start with the basics—tire pressure, chain lubrication, and weight reduction—then move on to aerodynamic improvements and battery optimization.
Remember, speed is fun, but safety and legality come first. Always ride within your limits, wear a helmet, and respect traffic laws. And most importantly, enjoy the ride. Whether you’re cruising through the city or exploring scenic trails, a faster e-bike means more freedom, more fun, and more reasons to get out and ride.
