How to Make an Ebike Faster: Speed Settings and Performance Tips

To make an ebike faster, first check the settings and components that affect normal performance: pedal assist, riding mode, battery charge, tire pressure, brake drag, gearing, and drivetrain condition. These checks can improve acceleration and help the bike reach the speed it was designed to deliver without unsupported electrical changes.

Speed settings vary by brand, model, display, and region. Use the manual for your exact bike before changing display parameters. If your current bike no longer fits the speed, terrain, or riding style you need, compare a purpose built electric bicycle rather than trying to turn one model into another.

How to Adjust Speed on an Electric Bike

Most riders can change how quickly an electric bike responds by selecting a different pedal assist level or riding mode. Some models also provide a supported speed cap through the display or manufacturer app.

1. Confirm the bike model and display. Similar looking displays can use different menus, so check the model name and display version first.
2. Select the pedal assist level. Use the plus and minus controls to choose more or less motor support while pedaling.
3. Check the riding mode. Eco, normal, sport, throttle, and pedal assist modes can deliver power differently.
4. Use only documented settings. Follow the bike manual or official app instructions for speed units, user speed caps, PAS levels, and sensitivity.
5. Test one change at a time. Begin at low speed in a clear area, confirm predictable acceleration and braking, then increase assistance gradually.

Changing the display from mph to km/h changes only the unit shown on the screen. It does not change the bike's actual speed. Wheel size, voltage, current, sensor, and controller parameters should remain at the values specified for the bike.

Pedal Assist, Riding Modes, and Top Speed

Pedal assist and top speed are related, but they are not the same setting. A higher assist level usually provides stronger support and quicker acceleration. It does not automatically raise the maximum assisted speed beyond the bike's designed limit.

For a closer look at assist levels, sensors, and rider input, read what pedal assist is and how it works.

Why Is My Ebike Not Reaching Its Expected Speed?

Listed top speeds are measured under specific conditions. Actual riding speed can change with battery level, total load, terrain, wind, temperature, tire pressure, road surface, and riding mode. Start with the symptom you notice instead of changing several settings at once.

If the bike shows an error code, loses motor support, or has an intermittent throttle or display, follow the electric bike troubleshooting steps before changing speed settings.

How to Make an Ebike Faster Without Electrical Modifications

1. Check the Current Mode and Battery Charge

Confirm that the bike is not in PAS 0, a low assist level, or an economy mode that softens acceleration. Move up one level at a time and use higher assistance only where the riding space and conditions allow it.

A healthy, charged battery helps the motor deliver consistent power. Use the battery and charger specified for the bike. A higher voltage battery is not a universal speed upgrade because the battery, controller, motor, wiring, and charger must operate as a matched system. The electric bike battery guide covers battery condition, voltage, charging, and compatibility.

Faster riding usually uses more battery. For real world mileage, battery reserve, and route planning, use the long range ebike guide.

2. Remove Rolling and Braking Resistance

Low tire pressure and brake drag can make an ebike feel slow even when the motor is working normally. Inflate the tires within the sidewall range and inspect them for damage, heavy wear, or an incorrect size.

With the bike powered off and supported securely, spin each wheel by hand. Light disc brake sound can be normal, but strong continuous rubbing or a wheel that stops quickly should be checked. Confirm that the caliper is aligned, the rotor is not badly bent, and both brake levers return fully.

3. Use the Right Gear and Maintain the Drivetrain

Shift to an easier mechanical gear before climbing so you can keep a smooth cadence. On level roads, move into a higher gear when the pedals begin spinning too quickly. The goal is to keep the rider and motor working together rather than forcing either one to carry the full load.

Wipe the chain, remove heavy buildup from the cassette and derailleur, apply a suitable bicycle chain lubricant, and wipe off the excess. For brake, tire, chain, and electrical maintenance, use the DIY electric bike repair guide.

4. Reduce Avoidable Load and Drag

Extra cargo affects acceleration and hill performance. Carry what the ride requires, secure bags so they do not catch the wind, and keep the total load within the bike's stated limit. On open roads, a relaxed and slightly forward position may reduce wind resistance, provided you can still see, steer, and brake comfortably.

How to Adjust Speed Settings on a Jasion Ebike

Jasion models use different displays and control systems. The correct method depends on the exact model and production version, so there is no single button sequence for every Jasion ebike.

For Models That Use the Jasion Ride App

The Jasion Ride App currently supports Hunter Pro, Thunder, Thunder Pro, and Thunder Pro ST. Available functions differ by model. A compatible bike may provide options such as:

• Speed unit selection
• User top speed cap
• Throttle speed limiter
• PAS level selection
• Maximum speed by PAS level
• PAS sensitivity
• Trip data and default settings

Connect the bike, review only the options shown for that model, and follow any restart prompt after applying a change. See the Jasion Ride App guide for download, Bluetooth pairing, settings, trip records, and compatibility details.

The video applies to compatible Jasion models. Screens and available performance settings may vary by bike.

For Models Not Listed as App Compatible

Models that are not listed as Jasion Ride App compatible should be adjusted only through the controls and settings documented in the exact model manual. Available menus vary by model, display, and production version.

Do not copy a P setting or button combination from another bike simply because the displays look similar. Before changing a setting, confirm the full model name, check the display and button layout, photograph the current values, and change only the options described in the model instructions.

Use the Jasion user manual download page to find the guide for your model. If the display becomes unresponsive after a change, begin with a normal restart and use the official instructions to reset an ebike controller and display.

Jasion Speed Settings and Listed Top Speeds

The table below shows current listed top speeds and the primary place to check supported settings. Product specifications can change, so confirm the current product page and model manual before adjusting a bike.

Higher speed models may not fit standard Class 1, Class 2, or Class 3 definitions in every operating mode. Rules can vary by state, city, road, trail, park, and land manager. Review the guide to Class 1, Class 2, and Class 3 ebikes and check the rules where you plan to ride.

Supported Speed Settings vs. Speed Limiter Modifications

Manufacturer Supported Settings

Some electric bikes provide documented controls for pedal assist, riding modes, throttle behavior, PAS sensitivity, or a user speed cap. These settings are part of the bike's intended control system and may differ by model, display, firmware, and region.

Electrical or Firmware Changes

Changing a controller, sensor, wire, firmware, battery voltage, or undocumented display value is different from using a supported setting. Such changes can affect speed readings, motor response, component compatibility, braking needs, and where the bike may be ridden.

If the bike is slower than normal, check its mode, battery charge, tires, brakes, drivetrain, load, terrain, and error codes before assuming a limiter is the cause. Riders comparing bikes designed for much higher speeds can read the 50 mph electric bike guide for performance and riding considerations.

FAQ

How do I adjust speed on an electric bike?

Use the bike controls to select the pedal assist level, then check whether your model offers a supported riding mode or user top speed setting in its display or manufacturer app. Follow the manual for the exact model and test one change at a time in a clear area.

How can I make my ebike go faster?

Check the current pedal assist level, riding mode, battery charge, tire pressure, brake drag, drivetrain, mechanical gear, and unnecessary load. These steps help the bike deliver its normal performance without changing electrical components.

Does a higher pedal assist level increase top speed?

A higher pedal assist level usually increases motor support and acceleration. Some bikes also assign a speed cap to each PAS level, but a higher level does not raise the bike beyond the maximum speed supported by its design and current settings.

What are electric bike speed settings?

Depending on the model, speed settings may include speed units, pedal assist levels, riding modes, a user top speed cap, a throttle speed limit, speed caps for individual PAS levels, and PAS sensitivity. Not every electric bike offers every option.

How do I change speed settings on a Jasion ebike?

Confirm the exact model and display first. Compatible models may use the Jasion Ride App, while other models rely on display controls described in their manuals. Do not copy a button sequence or P setting from a different model.

Which Jasion models work with the Jasion Ride App?

The Jasion Ride App currently supports Hunter Pro, Thunder, Thunder Pro, and Thunder Pro ST. Available app functions vary by model, so a connected bike may not show every performance setting.

Why is my ebike not reaching its expected speed?

Check the battery charge, pedal assist level, riding mode, supported speed cap, tire pressure, brake drag, drivetrain, total load, hills, wind, and temperature. A sudden change may also involve a brake signal, error code, cable, or battery connection.

Can I remove the speed limiter on an ebike?

Use only speed and PAS settings documented by the manufacturer for the exact model. Altering the controller, sensor, wiring, firmware, battery voltage, or undocumented settings is different from using a supported speed control and can change how the bike operates.

Use the settings documented for your exact bike and test one change at a time. If the bike operates normally but no longer fits the speed or terrain you ride, choose a model designed for that level of performance.
