Design offers a full-valuable bike that can be folded, stored in small spaces (cases, car trunks). Main feature is the circular frame allowing unusual folding. Both wheels have overhung mounting. After releasing safety lock nuts, wheels are turned around relevant axis into frame. Because rear wheel folds, momentum transfer from crankset to rear wheel must be divisible. Common chain system is replaced by belt system with outer toothing. Belt is mounted on two rollers. Both "Chainwheel" and pinion have outer toothing, ensuring right direction of turning and divisibility of the whole system.
Rear hub contains internally geared hub similar to Shimano Nexus system. GripShift type shifting.

Red safety lock releases saddle support to fold saddle down towards frame. To fold handlebars, first release revolving safety lock nut on top of head set. Handlebars can then be moved back towards frame. Bike is equipped with disc brake in front and clamshell brake at rear, preventing blockage of wheel folding mechanism. This bike will be welcomed by people in traffic-ridden cities, young people, students on campus. It can be used to good effect in large industrial facilities, airports, city centers as a rent bike or as a "parasitic" means of transport: user can park her/his car outside city center and bike to work."
