<p>#CMT# #/CMT# The bicycle can be converted from a conventional configuration into that of a recumbent bicycle. The main frame (1) is rotatably connected via a hinge (9) to the pedal frame (3) on which the crank assembly is mounted, allowing this assembly to be rotated between a position in front of the steering column and a position in between the front and back wheels. An additional hinge (21) connects the handlebars (6) to the steering column (5) in order to alter the height of the handlebars, which can be fixed into position in their uppermost position with the steering column extending vertically. #CMT#USE : #/CMT# A combined conventional and recumbent bicycle is described. #CMT#ADVANTAGE : #/CMT# The conversion requires no extra tools, both wheels can remain on the ground during conversion and no bicycle components need to be dismantled or fitted during conversion. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the bicycle in the recumbent configuration. 1 : main frame 3 : pedal frame 5 : steering column 6 : handlebars 9, 21 : hinges.</p> |
