A mid drive torque sensor makes pedal-assist more natural. Instead of kicking in too hard or too late, the sensor adjusts power based on pressure. Golden Motor includes torque-sensing setups for riders who want effort-based control. That’s especially useful for commuters or trail riders who don’t want jolts or lags—just smooth support that mirrors how they pedal. http://goldenmotor.bike/products/bafang-m635-torque-sensing-mid-drive-kit-48-52-volt-1000-watt
