A compatible Ebike Pedal Assist Sensor (aka Cadense Sensor) for my aging Vivi Ebike
The Chazcool X0048H617D Cadence sensor fixed my Vivi M026TGB Folding Ebike Pedal Assist!My 2+ year old Vivi Folding Ebike needed a new chain after 2300 miles and lubrication of various cables and joints. Adding oil to the left Pedal Crank Hub may have killed my worn PAS (Pedal Assist Sensor). This unit (see photo) is pressed into the Hub and activates the ebike motor when you rotate the pedals forward.What Happened? The Sensor popped out of the hub and was too loose to stay put. After a dozen or so re-insertions, the Pedal Assist stopped working while the throttle start continued to function.Finding a replacement Cadence Sensor (PAS): A Vivi replacement was out of stock. Unfortunately, there are a large variety of Cadence Sensor types available on Amazon so one needs to compare the Vivi OEM part against the candidates with the following criteria:1- Cadense Sensor Type (Not Torque Sensor)2- Same Form Factor and Mount: Press fit into left Pedal Crank Hub (non Splined type)3- Same Connector 3 Pin Barrel Female4- 5V Vdd, 12 magnet type5- 2 Hall Effect sensors embeddedThe Chazcool X0048H617D Cadence sensor offered from Amazon seems to be a close fit.The Results:1. Documentation: None supplied (therefore only 4 stars!)2. Comparison to OEM original:a. Fits very snugly into Left Crank Hubb. Connector is the wrong gender. The original has a Female 3pin barrel connector which required splicing this in place of the Male. (Black-to-Black, Red-to-Red, and Blue-to-White wires.)c. Installation: Use a crank-puller to remove left Pedal/Crank. Remove Controller Cover and disconnect PAS connector. Pop off the PAS. Use the old Femal Connector and splice in place of the male on the new unit. Press the new unit onto the left crank hub. Connect cable to the Controller. Reinstall the Controller Cover and use cable ties to resecure the cables. Reinstall the Left Crank/Pedal assembly.d. Operation Test: Success! Rotating the pedal forward after installation started the motor.Additional Comments:1. Don’t lubricate the left pedal Crank shaft bearing (where the PAS is located)!a. The Oil may have caused the worn plastic mating parts to completely release resulting in the 12magnet rotor slipping as well as causing the sensor body to pop off the Left Crank Hub.b. The bike had over 2300 miles with the OEM sensor which translates to about 800,000 pedal revolutions. The old sender, cleaned of oil, fits quite loosely into the hub while the new replacement fits snugly. The Plastic Magnet Rotor and Shaft ring are not lubricated and appear obviously worn.

Great throttle
Good all around throttle for e-bikes and scooters.

Fits Euybike F6B
Excellent but isn’t the right sex plug for Euybike. Had to splice my old plug onto this sensor but works flawlessly otherwise on Euybike F6B

Maybe I don’t get it.
The center part with 12 magnets is very difficult to rotate. About as hard as turning a nylock nut onto a threaded shaft. Plastic on plastic with no bearing and only trace amounts of lube.The opening is hex shaped, 6 sided, not 4 sided like crank shafts, or 8 sided like ground down crank shafts. There are no adapters. I don’t see how this thing is supposed to turn with the crank, it doesnt fit. There are no fitment instructions or printed material of any kind included. The cable has a hard right angle kink with nicked insulation right where the wire exits the body of the unit. There is no pinout information.
