We discovered a new mainland made bottom bracket torque sensor that operates on a 5 volt standard.
|5V Signal Bottom Bracket Torque Sensor|
Most e-bike brake handles, throttles, speed sensors, and LCD’s run a standard 5V+/- signal much like USB. Unlike many of the high priced German BB torque sensors that run on a strange variable 5.3~18v +/- system, this new 5V, affordable torque sensor opens a lot of controller possibilities. This is possible via small breakout “voltage adapter” box. We have had a very difficult time finding mainland controller manufacturers able to conform with the German standard of 5.3~18v +/-.
Not to mention this new BB torque sensor is almost half the price of the it’s German engineered equivalent. We will be testing this new torque sensor in the Spring season with a mainland made Sinewave controller and BPM geared motor.
Check back for our updates on this new find! Now if we could only source a reliable BB torque sensor with a replaceable cable connector coming out of the side so we don’t have to drill a cable exit hole out from the center of the bottom bracket….
|New BB torque sensor looks promising Albeit the center cable routing|
|Also need to test the IPXX water rating and axle hardness|
