This closed loop
system is a way of connecting the handlebars to the
forks on a recumbent bike. The idea is to use bike chain
to connect the handlebars to the forks. A tube is welded
to the top of each fork crown so that bolt can pass
through it. The bolt is used to tension the closed loop
system. The end of the bolt is flattened out, a hole
drilled into the end so that the chain can be clamped on
as they usually are using the chain pins. On the
handlebar side either a lug is welded onto the bars or a
metal strap wrapped around the bars with the chain
clamping on again with it's own pins as usual. The
handlebars could then mount using one of the ideas described here.
