HubSink Performance Guarantee
Your motor will handle at least double the power without overheating, or stop overheating at the power you already run. Or your money back.
HubSink does not make power. Your controller and battery do. HubSink lets your motor handle much more of that power without overheating, so you can turn your controller up.
Our guarantee
Fit HubSink with Statorade to a compatible hub motor and you will get at least one of these results:
- Handles double the power: your motor handles at least twice the power it could before without overheating, when you turn your controller up, or
- No more overheating: your motor stops overheating at the power you already run.
Most riders get both. They turn their controllers up to more than double their old power, ride harder and longer before the motor gets hot, and ride more efficiently, because a cooler motor has lower winding resistance and wastes less of your battery as heat.
