LBS or any other LBS doesn't physically repair a component part all they do is to diagnose the issue though diagnosis and then swap out any part if they have it in stock, other wise will order in from Germany or wherever in case of the drive unit wait until a replacement arrives after they have sent the old one away.

All bikes are the same you don't physically carry out a repair, no need for too much electrical knowhow often just a case of like for like replacement if part comes from the original seller.
Woosh, Kudos Wipser etc will send out a replacement part if you can't get the bike to them and all you have to do is unplug and unscrew something and fit all back again. If you aren't able to manage often they will find a solution to help you out through a third party.


The only time you need some leccy knowhow is with kit building and battery diagnosis if you like to tinker and know how things work, other wise it is plug and play.

Having external electronic controller and separate motor for hub drives bikes is double edge sword. Yes it is cheaper to replace components and repair if repairer has electrical back ground but not so easier for your average bike mechanic with no electrical knowledge.

With Bosch middrive, most LBS should be able replace motor easily enough plus Bosch provide diagnostic tools. Parts are easily to come by, its only drive, speed sensor, display and assist button module (combined in case of Purion). Expert help is only phone call away. Any LBS supporting Bosch drive can fix you bike even if its not one of their brands.

The bike manufacturer doesn't have to worry about after market support for drive system as Bosch has it covered.

In Woosh case they need to provide a complete set of spares for electrics include old and new models. The number LBS that would be capable of repairing Woosh ebike with electrical problems is also very limited.

NB I've used Bosch and Woosh as examples.
I think that's not quite right. Woosh use standard parts, as do most of the other brands, like Wisper, Juicy, Kudos, Freego, etc. Any competent electric bike shop should be able to fix any of them with standard parts that you can buy from Aliexpress. You can fix a Woosh controller by transposing parts from a Whisper and you can interchange motors between all those brands too.

I help out at the local electric bike shop doing their repairs. People bring in all sorts of interesting relics from the past, bikes that they bought from the internet and other ones where they don't have access to the brand's dealer. I could get all of them going again. The only time I was defeated was by a Trek with the Bionx system fitted because I was locked out by the software.

The analogy is PCs. If you buy an iMac or whatever it's called, you're stuck with iMac specialists to fix it, but if you buy a PC in PC World or from EBay or anywhere else, any PC shop should be able to fix it.

i am still not sure if this means a total motor replacement for a minor fault in the electronics with the bosch system?
apologies if this has already been pointed out

So all the chinese controllers and motors are interchangeable, use same connectors and pinouts?
They all have the same motor connector, so yes you can swap the motors. You can buy a really nice controller, LCD, throttle and PAS as a set with matching connectors for about £70, which will drive any motor.

On the cheapest bikes, you can often just a single item, like a throttle or LCD, but when you can get the whole set and your own control over the controller's parameters for £70, it's hardly worth it.
