Sumat up with my bike, some underlying fault that's yet to be addressed. What it is, right, there's something up with the freewheel mechanism - A few weeks ago I was rolling along all carefree and that when, without any warning, the back wheel seemed to sieze up, pitching me over the handlebars like an inept cowboy from a bronco. Anyway, I took it into the shop & the guy sorted it and didn't charge me anything, but tonight it happened again, except this time I managed to bring the fucker under control. Rolling along, then heard this kinda cracking noise and the pedals went all wierd. And when I was pushing the bastard home, the pedals were rotating as if it was a fixed cog rather than a geared bike.Dangerous as fuck though, it needs sorting - I'm half tempted to launch this bike into the canal and just buy another one, but I can't really afford to do that.
