Went to the garden and emptied the shed for a stock take, Ended up building my youngest a bike from all the bits and pieces knocking around. He only wants it to ride to the skatepark so he can go skateboarding. Mish mash of parts but it seems to work well.
Only problem I had was one brake arm binding up when tightened. Swapped the brake for a brand new Salt one (Special offer from Halfords £1) same issue. Pulled the arm off and found a build up of powder/paint at the bottom of the pivot, 10 mins with a stanley blade and issue resolved
