When the wheel spins up, under hard braking and with quick throttle changes, that leads to big current spikes in the controller — and those end with the protections kicking in and cutting power.\u003c\/p\u003e\n\u003cp\u003eAn encoder tracks the real rotor angle at every rotational speed and does it at a higher frequency. The result: a smoother, predictable power delivery, better throttle response, more precise torque control down low and no current spikes loading up the controller.\u003c\/p\u003e\n\n\u003ch2\u003eBefore you buy — what you need to know\u003c\/h2\u003e\n\u003cp\u003e50 kW is a multiple of what the stock Ultra Bee drive puts out.
