Most of this is taken from my post number #78 on a thread I started last year. https://www.pedelecs.co.uk/forum/threads/pswpower-after-sales-service.33423/
I recently purchased a Specialized Crossroads lightweight road bike from our local charity bike shop here in Bournemouth, "Hope to Cycle".
I bought it specifically to fit a new ebike kit. After much humming and haaing, I plumped for a kit from Whoosh, so glad I did. This is the kit from Whoosh: Tongsheng 48V 250W TSDZ2 kit with new VLCD5.
The kit arrived and I had real difficulty removing the bottom bracket. I eventually gave up after contemplating my large lump hammer on the bench and took it to the local bike shop Hope to Cycle. They had to employ a boilermaker's 3ft spanner to shift it after heating/cooling the bracket, eventually they shifted it.
I decided it may be prudent to get them to fit the motor while it was there. The only other difficulty was the gap between the bottom bracket and the motor housing is about 3mm. This is a crucial measurement and before getting a crank drive kit upend your bike and check the height of your guide, it cannot be more than 3mm from the crank bottom.
The guide for the rear gearset is attached to all standard bike's bottom bracket here and most are well over 5mm, mine was almost 15mm. There is no way the motor would slide into the bottom bracket housing with this guide in place. The bike mechanic tried 3 different guides, all had much too high a profile to allow the motor to slide into the bottom bracket. In the end, he said lose the guide altogether, let the bottom bracket decide where the cable goes and we will just hope for the best. Not a very satisfactory outcome, I'm a firm believer in the manufacturer knowing more than I, they do not fit extra parts for the sake of it.
This is the guide I cut down to 3mm with a dremel. 
Here is the fitted motor from underneath taken before I added the cut-down guide
I decided to remove the motor again and see what I could fabricate to replace the guide which had been discarded by the bike mechanic. I searched through his collection of old dumped bikes at the back of his shop and found a couple which were of a much smaller profile than the original.
I upended the bike and set to work with my dremel.
3/4 of an hour later, I had finally removed enough material to allow the motor to fit and still left enough material for the guide to do it's job.
I feel much happier now that the guide is back in place.
There are more pictures but this forum has a 10 picture limit per post. I'll put the rest in the next post.
