I volunteer at a charity recycling donated bikes which are fully serviced for resale. A few ebikes are donated which usually have dead batteries, no key etc so end up going for scrap afted stripping any usable non E parts. All of the bikes have been purpose built as Ebikes and with batteries...

It is an integral sensor as in your picture, and I can see it is turning correctly. I have been watching several you tube features which seem to suggest the odometer display comes from magnets in the motor hub itself rather than the pas sensor. Maybe I need to be investigating there. From my...

If an all in one sensor And your bikes crank axle is a shade wider in diameter than the expected 17mm the sensor can 'catch' and turn until the cable is pulled taught, this can result in a very inconsistent motor engagement.. (the problem i had.. if a 2 piece with a separate magnet disk...

Thankyou for your helpful reply. I've decided I will send it off to the ebikemotorcentre who get very high recommendations on here

The mode of failure goes something like this: Thr crank seal wears and let's in a bit of water. The water gets into the bearing and damages it. The excessive play in the bearing damages the seal further and let's more water into the motor. From there the water can get into the electronics or the...

What have you tried to make it work ? As then we may be able to help Does the LED display light up /turn on ? If so ; is the hub motor connector 100% fully pushed home to the embossed line marked on the hub side of the connector ? Does the PAS red led blink on/off when the crank is rotataed ?

36v would help a lot. All the 24v controllers I tried at 36v worked OK, but I can't guarantee that it won't blow. If you want to be more sure, open the controller and look at the big capacitor in it. If it has a voltage rating over 42v, it should be OK, most are 53v or more. That's the thing...

Eventually got the new (Brainpower) controller shoehorned into this very old Giant Twist Express. Fitted a PAS to the crank, as the torque sensor on the rear dropout needs a bit of voltage shifting/remapping to work with the throttle input, and I can't be bothered to do anything until such time...

To be legal, the motor needs to be marked as rated at 250w by the manufacturer. If it has that marking, it's legal. There is no law about how much power it can make, nor how much power you can push it to. It's output power that determines how well a motor drags you up hills. The more power you...

The way "power" impacts on hill climbing is the speed you get up them, the work in climbing is achieved by the "torque" developed at the rear wheel. It does typically follow that the more power available tends to also come with higher torque, but as said in respect to climbing it is torque that...

I have a BBS01 crank motor with a flashing speed sensor on the back wheel. The LED only lights when the magnet on the spoke passes the sensor and then it goes off until the next revolution when it flashes again. That is the expected behaviour I think.

I have a Freego Martin city with a central crank drive,(Bafang) motor . Dose anyone know if I can fit a Throttle push switch on it so I can use it without pedal assist, ? You can push the + button on the controls to make it walking assist, Any ideas would be appreciated. Looking forward to any...

Yes you’re absolutely right another and the MPH is working fin, this is just on test in my workshop. Many thanks for your expertise and help certainly appreciated

The speed sensor would be inside the motor if you have one. That's the one you can replace by a wheel magnet type. the sensor on the crank is the pedal sensor. You might want to have a look on the wheel or chainstay to make sure you don't already have a wheel magnet one, where the magnet's been...

The gear is scheduled to arrive at end of the month. I tried cleaning the old gear. It was easy to remove by hand. No puller needed, Remove pedal and crank gear. Motor cover held by four small screws. Remove circlips (I had a tool), The big gear lifts off. The gear has two clutch bearings in...

Thanks Saneagle, I built the Way farer for larcher chaps and chapesses! I was 21 stones at that time and it was designed with me in mind. It's very strong albeit a little heavieer than the average ebike and at £1599.00 a great buy. All the best, David

sweet, Ill leave the chain for now and if need be take it into the evans cycles by my work and ask them to swap the chain for a more robust one in the future. Ill just stick to replacing the crank and chainring then.

A quick search suggests this is a hub motor, so crank should just be standard bike components, so just needs a normal crank arm puller. Remove the dust cover, use a standard socket of the right size to undo the bolt, then screw in the puller and off the crank will come. Your chain will be...

My wife said her TSDZ2B pedals were slipping intermittently. I tried turning the pedal by hand. Sure enough, it's slipping and I can spin the pedals freely by hand w/o the chain/crank moving. What a POS motor. That's a clutch fail. I watched the Tong Sheng video. Guess I need to rig a crank...
