Ridstar Q20 Pro Controller FAQ
Will this 2000W Ridstar controller make my Q20 faster?
You may gain Ridstar Q20 Pro 1–3 mph top speed depending on battery voltage and motor RPM limits. The biggest improvement from the Ridstar Q20 Pro controller is acceleration and torque, not extreme top speed. It handles dual 1000W hub motors (front and rear) with a dual 28A current output layout designed to manage independent front and rear power flow.
Is this better than doing a shunt mod?
Yes. A shunt mod increases current artificially and can:
Overheat the controller
Trip the battery BMS
Shorten controller lifespan
Cause unpredictable behavior
This Ridstar Q20 Pro controller upgrade is properly rated for higher sustained current for your ridstar q20 pro electric bike.
Can I use this Q20 1500w controller on a single motor Ridstar Q20?
No. This 2000W controller for dual motor dual battery ebike only (Ridstar q20 pro).
Is this compatible with 72V battery upgrades?
No. This Ridstar 48V / 52V controller is designed for Q20 Pro 1500W systems only. If upgrading to 72V, you must use a 72V-rated controller and ensure motor compatibility.

One thing I learned is that not all Ridstar controllers are identical. They helped verify the plugs before shipping. Everything matched perfectly and no wiring modifications were needed.

I did the shunt on the new Q20 Pro controller for Ridstar dual motor 1500w version, It’s definately a wheel spinner. Tested speed on the flat and topped out between 33 and 34mph.
