Whipped up this bike for the whanu to ride over the xmas break, I couldn't find too many cheap practical solutions on here for the great bafang mid drive for a bike with the 100mm bb - so here is one idea that sorted it for me
After a bit of a measure up I cut about 10mm of on the sprocket side with the angle grinder.
And on the other took of near all of it right up to the stay, I think I got roughly 75mm in the end, not enough for the lock nut but plenty of meat for the one, squared it all up by eye with the belt sander checking with a square a few times, hit it with the rotary grinder inside, sweet as,
sprocket on backwards and seems to work no worries.
Cranks are a bit of an issue, the right hand single speed that came with the bike fitted stock - once i ground out the sprocket.
The LH one i tried bending cold and it worked like a charm, in the vise with pipe on, put the pain on it and no problem, took a few goes to get it right and few more to true it up, seemed to handle it fine.
what I like a bout this bike is it is solid as a rock at speed , esp good at being ridden with no hands, and shes a head turner, i barely got a look at my much better bikes on Christmas day, this is the bike they all want to ride!
