All speeds are relatively rounded to the nearest 0.3 mph and are approximate numbers. Reaching a certain speed is influenced by wheel size, wheel width, wheel durometer, rider weight, weather, terrain, riding mode defined in remote, battery percentage and more. The numbers given are applicable to a 165 pound rider, riding on a full battery on flat terrain. 

Please do not use AT wheels on the ONSRA Black Carve Direct Drive Board - it’s dangerous and can lead to serious injury. 

The recommended wheel size for the ONSRA Black Carve Direct Drive Board is between 97mm up to 130mm, for the Dual Belt board it’s between 85mm and 180mm.

When you switch wheels make sure to switch the wheel size settings on your remote accordingly to the exact size of your wheel.
Riding with double kingpin trucks at high speed is only recommended for experienced riders wearing full protective gear (helmet, pads etc.). Make sure to tighten the trucks before your ride.
