One Mode Fits All

We optimized our controller to have a smooth throttle through acceleration and to get the most top end speed you can out of the battery your using. You won’t need an eco and sport mode – you now have one mode that delivers all usable power, when you need it, resulting in a great riding experience.

4000 vs 8000

Through extensive testing and collaborating directly with ASI, it is clear that the BAC8000 outperforms the BAC4000. The components are designed to deal with higher amperage, and can therefor dissipate heat and operate at lower amperage very efficiently. This is noticeable in the low end, top end, and most of all for regenerative breaking.

That said, the BAC4000 is also a great product that can handle the stock battery or stock battery with a BMS bypass and upgraded breaker.

We are also offering custom builds for anyone with their own battery, motor, throttle, etc. Contact us to get a quote.
