Alright mate I’ve ordered a new one, should be here Wednesday, thanks for your help . Cheers

Yeah I’ve tried that, I did 3 different magnets just to be sure lol, I took the sensor off the bike but still connected inside, waved the normal one off bike, at different distances and had someone check the display, nothing, I used a fridge magnet and a strong one to test this, still nothing...

Hi guys just took the sensor off the mounting bit, only thing I can see wrong is that there is a crack where someone had tightened it too much

Hi there thanks for the reply, I have just tried using a magnet to see if it shows any speed and it still doesn’t unfortunately. Would I have to be pedaling at the same time for it to show this? Thanks for the help mate, cheers

Oh yes I can imagine that’s very hard to fix, mine is just from the back wheel into the motor under the crank, it’s just 3 big bolts and 2 little Alan keys, internal cabling is quite tricky. Thanks for your help joe. I’ll keep you updated, all the best

That’s great to hear, thank god it’s not a motor issue , I’ll find out what sort of speed sensor is on it and I’ll order one and try and fit it myself, I basically had it off today just needed one bolt. Thanks for the reply Joe!

Hi guys, quite new to e-bikes, hopefully somebody can help me out, I recently purchased a haibike hardseven and it had a issue with it, Here are some of the symptoms that are happening; Odometer flashing Speed staying at 0kmph Motor kicks in for a second then does not give any power, same with...

Hi all, I received my new sensor today and popped it on before I did the continuity test and it works perfectly fine, no E21, but I did get an E00 30 seconds after I turned it on, I turned the display off and on and it was gone, rode about 2/3 miles on it and all works well, when I put the new...

Can you point me somewhere that explains how to do this, I have a multimeter. Thanks for your help!

No no wires are showing, but there are some bends on the yellow one. Also could this error 21 be the wire that connects to the ecu? That’s what I’m worried about. Thanks

Hi mate took all the silicon off, nothing much, the board seems ok, there is a couple of nicks in the wires and bends but nothing too bad, here’s a picture. I put it on without the silicon still error 21. Also when I plug the sensor into the connector there is no click, should there be? Thanks

Ah okay mate thanks for that, I’ll do that tomorrow and have a look, I’ve bought a new one already but it’s worth a shot to save me some money, also would this sensor issue cause the code 00? Because I do have a smashed lcd display and thought that’s it. Thanks

Hi I bought a new one just before as I took the sensor off again and had a close inspection, it doesn’t look good but wondering would it still work, here it is. Would a new sensor sort this issue and if not what else could it be. Thanks

Error 21 still continues, I’m not sure because it looks fine, I will post a picture of the sensor itself and see if I need to buy a new one. Thanks

Hi guys, today I bought a 2021 carrera vengeance e bike, it has error 00 and 21 I knew it had a error 21 and thought that there was no speed sensor on it, I turned the bike over and it was below the crank, I then repositioned it to the correct place and put some wd40 in the connections, then I...

thanks for the advice

there is no handlebar throttle, its just off the pedals but yes, it does kick in when requested, also when not requested!

Hi guys, thanks for the replys, we have checked it all over and its bone dry, i am pretty sure its not water related, however, its giving error 22 everytime it reaches 15mph now, and the bike trys to ride away on its own when switched on, evern when not on the bike, its quite dangerous...
