Sinclair A-FRame Folding Bike
I am trying to renovate this bike, another unique design by Sir clive Sinclair, which turns out to be more like repairing a hoover, because of all the plastic covers and bolts.
It is very unusual, with 2 tiny drive chains to make the bend from pedal to tiny rear wheel.
The main problem is the rear brake cable. This was completely jammed, and on disassembly I found two brake cables, connected by a slide. I don't know if this is original, but the wires were so corroded I could not work out where the slide is supposed to be i.e. the correct length of each cable. I assume the slide, which is 50mm long an has two channels - one for each cable. It must be connected to the folding process, but although I have found the user manual, this does not cover brake cable replacement.
Has anyone had exprerience of this bike. PDF attached with user manual.
