It's about time this thread had a photo!
Jeremy Torr taking part in the Wendover Bash Hillclimb, 17th June 1984.
His bike is an English Cycles' - Range-Rider
, and is based on the Geoff Apps' - Range-Rider design.
The main difference between the Range-Rider and the Aventura model is that the handle-bars are lower and wider than the Aventura which had a rear rack built into the frame.
The English Cycles' Range-Riders had a standard 70mm bottom Bracket and so the chainstays needed to be curved, (Clelands were 90mm with straight stays). They mostly used drum brakes, like this one, though some were fitted with cantilever brakes in order to reduce weight. They also lacked the mud-guards, bash-plates and chain-cases/guards of the Cleland Cycles' machines.
English Cycles made Geoff Apps' style bikes between 1982 and 1988 ish?
Cleland Cycles made its Aventura machines between 1982 and 84.
