Just had to change rear tyre on my grandsons bike, it’s an Early rider belt drive. When I’d re assembled it the belt kept moving across rear cog towards frame as the wheel rotates.
Before I removed wheel I checked the tension on the belt and it wasn’t as tight as I’d expected.
Anyway after quite a bit of faffing about eventually got it to stay in line, but has anybody got a procedure that works with minimal faff?
