摘要： The subject of the invention is a bicycle with a drive on front wheel, which after turning the handlebar by cca 110° relative to the frame of the front wheel considerably reduces its overall dimensions and which can be easily adjusted tor two persons.In this bicycle the train e consists of the frame (1) of the front wheel (15) and the frame (2) of the rear wheel (16), with the seat (19) and a back-rest (14) fixed. Both frames are coupled with the joint (3) and the crossed line transmission (10, 11, 12). In this coupling the axis of the joint (3) which is a part common to both frames intersects the floor surface in the point (C) at an angle of 69°±3°, at a distance of 20±4 cm behind the point of contact of the front wheel with the floor. Applied drive system (18) is placed preferably on the axis of driven wheel, and it consists of the crank system (17), planetary transmission and the one-way clutch. The handlebar (7) is mounted rotationally in the swivel axle (4) of the frame (1) of the front wheel and is immovably fixed through the swivel axle with the big wheel (10) of the crossed line transmission. The swivel axle (4) of the frame (1) has two bearings (8), (9), where the bearing (8) at the handlebar (7) is a bearing of small friction momentum, while the bearing (9) at the wheel (1) of the transmission is a transverse slide bearing with big friction momentum. The ratio of the crossed line transmission (10, 11, 12) equals to 1.4±0.1:1. The small wheel (11) of this transmission is immovably fixed to the frame (2) of the rear wheel (16) in the axis of the joint (3) coupling both frames (1), (2), and the big wheel (10) of the transmission is immovably joined through the swivel axle (4) with the handlebar (7) and rotates in the axis (6) of the swivel axle (4) of the frame (1). The line (11) joining the wheels (10 and 12) of the transmission crosses between the big wheel (10) and two relief rollers (13) placed close to the wheel (10).

摘要： An adult scale three-wheeled device facilitates movement for mobility challenged persons. The device is foot propelled while seated either through walking while seated or pedaling. The device is provided with a limited footprint for navigating confined areas while the individual is seated in a substantially standing position, with the pedals being repositionable so as to allow unobstructed walking while remaining seated. A lockable braking system prevents one or more wheels from turning. The device is collapsible for storage.
