Just spent 2 hours in the garage with mine. I knew the freewheel freewheeled in both diections so I'd bought a cheapie but it kept getting worse.....
The tyres were worse than I thought, one had separated from its bead and my finger went through the side wall of the other
Had the choice of Panaracer Spikes or some slightly hard/crusty physcos so went for the latter.
Bent rear axle was put back kind of straight with a lump hammer and a vice, then had to adjust and grease every other bearing. To cap it all I wrapped the rear mech round the spokes of the back wheel and twisted up the chain test riding it up the road. Argghhhhhh!!!
Found a suitably crap chain and rear mech and it does now ride. Well kind of - the drive chain sounds like its going to blow up at any minute, I think the front chain wheel is a different pitch to the chain/freewheel - we'll see how long it lasts!!
See you all in the morning
