Our resistance varies by how hard you pedal.  20mph = almost 150 watts, and 30mph = almost 250 watts. Factors such as tire pressure and tire size will impact resistance as well.

Crown Roller is Clever, but not currently smart.  

For riders interested in online riding platforms, we suggest using your own power meter. A less expensive option of a Bluetooth or ANT+ speed/cadence sensor works wonderfully as well.  

Last, we manufactured a recess in the endcap of the rear roller so you can add a magnet and after-market sensor like the Elite Misuro B+ without mounting anything to your bike. 

The center (widest) part of the roller is 85mm (3.35")
