How Fast Do Rad Power Bikes Go? (And Top Speeds)

If you’re thinking of purchasing a Rad Power Bike or are already an enthusiast, wondering how fast can a rad power bike go is probably a question you’ll be asking. This article will cover the max speed for the bike, how to override the default speed settings, and what other riders have experienced.

How fast do rad power bikes go? Rad power bikes have a top speed of 25mph (40 km/h) without pedaling. European models are programmed for a maximum assisted speed of 25 km/h. Many riders have gone faster than the programmed limits by pedaling or riding downhill.

Max Rad Bike Speed

Rad Power Bike motors can continue to deliver power all the way up to 40km/h. As the speed increases, the motor will start to taper off and eventually stop contributing power. You can, of course, continue to pedal and go faster.

Here’s what Rad Power Bike has to say about the max speed:

All ebikes by Rad Power Bikes have a top speed of 20 mph (32 km/h) without pedaling, which is the legal limit for street legal ebikes in most areas and in accordance with nation-wide ebike laws.*

*European models are programmed for a maximum assisted speed of 25 km/h in accordance with European ebike laws.

While Rad Power Bike claims these are the limits, their bikes can be programmed to go faster.

Increasing Your Max Speed

While this isn’t a speed hack, you can program your max speed on your Rad Power Bike. Rad Power Bikes come programmed at a certain speed, which you can increase using the LCD display.

Here’s a quick tutorial:

1. Turn your Rad Bike On
2. Press and hold the up and down arrows until the screen changes
3. Hit the mode button until you see a number next to km (mine said 32km). Use the up arrow to change it to 40km (the max it allows), then hold down the mode button to exit.

Max Recorded Speeds

Before we go over some impressive numbers, going faster than your legal speed limits is not recommended. Biking at fast speeds can be quite dangerous and a helmet should always be worn.

With that being said, here are some speeds that have been recorded on Rad Power Bikes owners:

I hit 46mph on my Mini ST today and though I was careful, it handled well down the big hill and slow turn or two behind Fred Meyer .

Once again, guys. I wouldn’t trust these bikes at high speed. I have gone as fast as 27mph on my Mini. It certainly didn’t feel too good. The fat tires and the general geometry of the bike, along with the often low – end components are not for going fast. Be careful out there!

I did 45mph on my Rover on a public road. It felt solid and safe.
