Rad Power Bikes are class 2, which means they are limited to speeds of up to 20 miles per hour out of the box.
Luckily, it is possible to raise the maximum speed of Radrunner to 25 mph/40 kph.
In this article, we will discuss the top 3 speed hacks for the Radrunner speed upgrade and the three main components of the Radrunner e-bike that have a direct influence on speed and torque.
Components of an eBike Responsible for the Speed
1. The controller determines the amount of torque and acceleration of the e-bike and sets limits to the maximum speed possible.
2. The motor, on the other hand, is responsible for directly making the e-bike move forward.
The more powerful the motor, the more speed, and power the e-bike can generate. E-bike motors are measured in terms of wattage, with more watts indicating a more powerful motor.
3. The higher the voltage of the battery, the more potential power can be fed to the motor.
If a rider upgrades from a 36-volt battery to a 52-volt battery, they will likely see a few more miles per hour from the upgrade.
Top 3 Radrunner Speed Upgrade Hacks
1. Upgrade the Controller
The controller regulates the amount of power fed to the motor. Upgrading the controller to a higher amperage can increase the speed and torque of the Radrunner.
2. Upgrade the Motor
Upgrading the motor to a more powerful one can also increase the Radrunner’s speed and power. Be sure to choose a motor that is compatible with the Radrunner’s specifications.
3. Choose batteries of higher voltage
The main battery is one of the main components that affect an e-bike’s speed and torque. Upgrading to a higher voltage battery, such as a 52-volt battery, can increase the Radrunner’s potential power.
Can Changing the Tires Boost the Speed of Radrunner?
Another way to improve the speed of your Radrunner is by changing the tires. The default tires that come with the bike are 26-inch by 2.3-inch tires, which are great for stability and traction but might not be the most efficient for speed.
You can try replacing the default tires with narrower and slicker tires that have a lower rolling resistance. This can reduce the drag on your bike and improve its top speed. However, remember that this might also affect the handling and stability of your bike, especially on uneven terrain.
Upgrading Speed with PAS Level Adjustments
PAS stands for Pedal Assist System, which is the mechanism that powers the electric motor on your Radrunner when you pedal. By default, the Radrunner comes with five PAS levels, which determine the amount of assistance you get from the motor.
The higher the PAS level, the faster you can go.
If you want to increase the speed of your Radrunner without making any hardware modifications, you can try adjusting the PAS levels.
By setting the PAS to the maximum level, you can get the most speed out of your bike. However, keep in mind that this will also drain your battery faster and might affect the overall range of your bike.
If Changing the Gear Ratio works?
The gear ratio of your Radrunner determines how much power is transferred from the pedals to the wheels. By default, the Radrunner comes with a 1:1 gear ratio, which means that for every rotation of the pedals, the wheel rotates once.
If you want to increase the speed of your Radrunner without upgrading the motor, you can try changing the gear ratio.
By installing a larger chainring or a smaller cog on the rear wheel, you can increase the gear ratio and get more speed out of your bike.
However, remember that this might also affect the torque and acceleration of your bike, especially on hills.
Conclusion
In conclusion, understanding the three main components of an e-bike and how they affect speed and torque can help riders make informed decisions when choosing an e-bike or considering upgrades.
The controller regulates the amount of power fed to the motor, the motor directly makes the e-bike move forward, and the battery provides the potential power to the motor.
While minor factors can also influence the speed, riders should pay attention to these three main components to achieve the desired level of performance from their e-bike.
