O.k , thanks . Looks like your route then is to try the 36 possible phase /hall combos, to see which two or three may work. 1633819796453-png.44350 (957×543) (pedelecs.co.uk)

There are very few places that will check it out and know how to recover such a battery, for the most part battery tech knowlwedge lies with the DIY enthusiast who have the know how and skill . One can do a simple check with a voltage meter after charging the battery, the voltage reading may...

One expects it wasn't looked after since it's last use and is now likely very unbalanced or knackered , sadly with some lithium ebike batteries they often need checking and charging for 10mins or so during quiet spells when not used. Initial thoughts are that it is badly unbalanced and one...

I'm not convinced that PAS and throttle wiring are 100% correct and really find it unsual to see PAS having a white wire as signal. Have you physically traced the wiring to snure it is correct or ar ejsut assuming it is correct.

With any large bike one has to think of the security and storage first most.

The thin wire connectors connect to a BMS safety device for the battery.

A two piece magnet disc and sensor is the best one to get, I opt for a bz10c that fits behind the chain ring. Otherwise use use a 8 pole model and fit it to the LHS. Behind the chain ring one simply finds a way to a fix the disc to the chain ring so epoxy glue or amechanical fixing, the...

We can only guess at the motor rpm/winding so for a 20" wheel at 25km/h ,the wound speed might be approx. 260/270 rpm. Built in to a 16" wheel one might see 13 , 14 mph if you are very lucky.. The answer will only become clear once a wheel is built and tested . One may have to settle for...

Yep 100% agree .

A different take on the Chinese fire balloons.

Those figures are good, your 03 error then is a wire issue so somewhere you have a faulty wire /connection. Make sure the motor connector is pushed 100% all the way in or has no bent misaligned pin inside.

The controllers don't cover triple voltage as they dual voltage models, either 24v/36v or 36v/48v.

Initial readings show two Hall are toast though one should completet the full test one should see near 5v as the Blue does and similar to near 0v when switching. If they don't that is the reason why error 03 is showing and why the motor doesn't work. Disconnect all of the motor halls at the...

20v dc.

Also are you 100% sure the the Black/Red & White wire connector is the PAS wiring as I'm sure you have the throttle connected to PAS. In #16 you show a pic of the PAS sensor Red /Black /Blue connected to controller throttle, Red/Black/Blue or Green for PAS sensor makes sense to me and is a...

I assumed you had 36/48v controller but #1 shows the description in the pic as 24/36v controller. Not really sure why it isn't working but the 03 error suggests to me that you do have a motor Hall or wire fault, so we need to fault find and start from the beginning. Start from scratch and just...

In the advent of the battery catching fire whilst being dangled , you have forgotten the water filled butt for it to fall into.

We need to see a pic of the battery and nay volatge labelling.

Confirm your battery voltage please as you have stated 26v ? C12 4 is the default setting but if your battery is 26v then no wonder the bike doesn't work.

It was parked under a no parking anytime sign , so could be some truth in the suggestion the fire was deliberate.
