This Vindec ‘Hi Riser’ looks to have been abandoned on Queen’s Lane. The Hi Riser was made by the Brown Brothers Ltd in the 1970s in the UK. This version looks to have a four speed dérailleur. Other models had a Sturmy Archer 3 speed hub. It was a cheap version of the more popular Raleigh Chopper. (which is quite popular with random comments.)
