Hi all, have just taken bike back to dealer, error code showing motor stall, warranty expiries in 2 months so wanted to get sorted.
Mechanic called can’t find a fault but they don’t have any software diagnosis machine he has just been turning it on and off numerous times. Is this acceptable or would you question there methods?
many thanks Brian

It is pathetic and almost useless.

Diagnostics needed if a mid drive closed system, imv if they don't have the diagnostics they shouldn't be selling them. It will need sorting before the warranty is up so another dealer with the ability and get the shop to pay for it if a charge is made.

Thanks to reply’s, it’s a rear hub drive, but I am concerned that it will happen after warranty.

If it is a hub motor then most lbs will not have clue how to diagnose.
Motor stall is over current/torque overload to the hub and can cause winding failure if it is prolonged, over current manifests it self as excess heat.
Under what circumstances did this occur ?

If you find the hub has lost power or feels gutless then it is has been cooked.

Has the error code cleared ?

I agree.
My tip is to talk to a friendly lawyer, and get him to draft a letter, requiring imminent fix or money back.
You may even be able to write such a letter yourself, and get it delivered with recorded delivery where the recipient must sign for it, a possible cheaper alternative, though here, they would still have to pay the lawyer's cost.
I cannot say what the UK allows, sorry!
regards
Andy

They are going to replace the controller, I have no knowledge if it’s the correct thing to do or not, they have a new wheel and motor but have said it must be the controller, any thoughts welcome.

The controller is the brains of the bike and controls the current delivery so that is likely the place to look, the motor only takes what the controller can give.

Show us the display and buttons, one should be able to enter settings to change basics like speed and wheel size.

Do you have to hold a pair of buttons to get in to the menus ?

To follow up on this saga, having been in touch with dealer their response is having looked at a display in the shop it also show’s 20.5 km/h.
they have ride it on full assist and say it assist up to 15.5 mph. So mine is correct. I am now totally at a loss what to do. Help needed.
