Presenting the ultimate small powerhouse for Onewheel® ONLY.  An incredible state-of-the-art, VESC-compatible unit (where the DRV chip is no longer needed).

You can customize all of the settings on this dynamo using VESC-tool.  Link two together using a two-wire CAN cable, for dual motor applications.

Nothing else on the market delivers this sort of power in a reliable, small package!

If you want gobs of reliable power on tap for your

Onewheel®, with the ability to self-customize all the parameters, this is it!

The Tronic™ 250R makes your motors silent, but extremely powerful.  And with the auto-configuration options in VESC Tool, it's easy to use the motor detection wizard, and then manually configure the other various settings and preferences to your liking. Tweak the parameters and dial in the best performance for your ride. It's addictive and fun when the hardware is reliable.

Note: A simple latching switch of your choice works as the power on/off button (not included, but many great options are on Amazon). It's a reliable setup and meant to last.

Imagine what your PEV would do with this VESC Controller. You have to try it!
