A device (1) for the assisted movement of a pedal assisted bicycle, comprising:
- an electric motor (2);
- a first (5') and second shafts (5") laterally projecting on two opposite sides of the device (1) for fixing the device (1) to portions (6', 6") of the bicycle frame at a first (14') and second fixing seats (14"), respectively;
- means for coupling the device (1) to a bicycle wheel in order to convert the motor movement (2) in a rotation of said wheel around said first (5') and second shafts (5");
- first and second means for connecting the first (5') and second shafts (5") to said frame portions (6', 6"). Said first (5') and second shafts (5") comprise a first (10') and second connecting seats (10") at their ends, and said first and second connecting means comprise a first (11') and second connecting pins (11") fixedly and removably coupable to said first (10') and second connecting seats (10"), and connectable to said first (14') and second fixing seats (14") of the frame. Said first (11') and second connecting pins (11 ") are shaped so that their lateral portions laterally project from said first (10') and second connecting seats (10") of the first (5') and second shafts (5") so that said their projecting lateral portions engage said first (14') and second fixing seats (14"). |
