The short answer: fast. 

No, really, though. The 750W BBS02 is the fastest street-legal kit available in the United States. Paired with our 52T sprocket and the mechanical advantage of a rear gear cassette these motor kits can typically achieve speed of 25+ mph (depending on your unique setup). 

The BBSHD 1000W motor kit is SERIOUSLY FAST! Wheelies and speeds of over 30+ mph may be possible with this motor (depending on your unique setup). 

The 500w Front Hub Motor can achieve speeds of 20mph+.

The top speed that you can achieve with our motor kits on your specific bike setup depends on many factors: front sprocket size, rider weight, weather, terrain, whether you are pedaling with the motor or not, wheel size, etc. Unfortunately, we cannot guarantee or tell you what speed you will be able to achieve as it depends on a combination of many specific factors that are unique to you as the rider and your specific bike setup.

If you want to get into a more in-depth estimate of the max speed on your bike we have provided a helpful link to a bike speed calculator below:

You will need the following information in order to determine the theoretical (not guaranteed) speeds based on the kit you choose and your bike's gearing! Please note, this is just a rough estimate and in no way a guaranteed speed!

The example provided below is to show the theoretical max speed of a standard 26" bike with a 42T front chainring and a 7-speed cassette with an 11T smallest gear with each of our motor options:
