FIELD: transport engineering. ^ SUBSTANCE: invention is designed for converting standard bicycle into tricycle by fastening car instead of front fork. Connecting device 3 of car 1 has upper and lower parts with axle tilter relative to bicycle frame 8 to provide tilting of bicycle frame 8 to side of cornering. Connecting device 3 consists of upper and lower brackets on car 1. Plate fastened to frame 8 through hole for passing front fork of bicycle is hinge-connected with upper bracket of connecting device 3. Tube consisting of two parts connected by two cover plates enclosing tilted tube of bicycle frame 8 is hinge-connected with lower bracket. Tube is secured in its rear part by two cover plates in unit of under-saddle intersection of tubes of bicycle frame 8. Wheels of car are mounted on cantilever axle. Synchronous operation of caliper brakes of car wheels is provided by tensioning of cable, common for two brakes, and passing along steering tube of car skeleton. When brakes are used as parking brakes, cable is tensioned and put on hooks on said tube. Sides of car are made of gauze. Hinged front board can be fixed in horizontal position. Car is provided with seat for passengers, which can be used as tent for covering loads, or as sail. ^ EFFECT: increased load carrying capacity of car, possibility of use with any bicycle without its modification. ^ 4 cl, 17 dwg
