Let's take a closer look. There's a lot Sinclair gets right: the A-bike weighs only 12lb (little more than half most bikes); its chain is completely enclosed (so no more trousers ruined by grease marks); and it folds up in 15 seconds (whereas most folding bikes demand an NVQ in mechanical engineering). So maybe the A-bike is just what urban commuters - the park-and-ride crowd or rush-hour train travellers - need. Sinclair might just have cracked it.
