Bad news.. my single speed project is put on hold. Today my son friend came to repair his bike. The challenge are the bike uses 600cc tyres and the rear rim is busted. So I gave him both my 700cc rims.The 600cc old rims. Could not find any bicycle shop that sell the tires and rims any more.
The crank setup and the single speed freewheel. (note the derailleur is not remove requested by owner)
The completed bike. Plus the proud owner.
