Abstract
The bike (10) comprises a frame provided with a front wheel (12) oriented by a handlebar, a saddle (39) and a crankset. The bike (10) further comprises two pivoting rear uprights (18, 19) each carrying a rear wheel (22, 23), the pivoting rear uprights being mounted by independent pivot links on the frame. The crankset actuates two drive means (26, 27, 59, 60) independent of the rear wheels. The drive means of each rear wheel comprises a free wheel (59, 60). The drive means are configured such that, in a bend, only the rear wheel located on the inside of the bend is driven by the crankset, the rear wheel located on the outside of the bend freewheeling and not being driven by the crankset.
