NOVEL TYPE OF COLLAPSIBLE CYCLE

摘要

The invention concerns a novel type of collapsible cycle capable of combining maximum compactness with satisfactory moving speed. Said cycle is provided with a frame of small dimensions and a simplified architecture, not including any extension in height. Said frame consists of a rectangular tube (1). At one end is fixed the steering column (2) and at the other a U-shaped part (5) whereon is fixed the rear wheel. Two triangular plates (6) are welded on either side of the tube (1), and comprise a transmission consisting of two successive overdrive gearsets, thereby providing sufficient development in spite of the very small wheels. An articulation (15) above the steering column (2) enables to fold down horizontally the assembly at the end of which is located the handlebar. A shroud covering the frame and the transmission protects various projections. Said very compact and manoeuvrable collapsible cycle is particularly designed for urban trips and for acrobatic manoeuvres.
