ONE-TRACK BICYCLE Russian patent published in 2011 - IPC B62K3/00 B62K21/00 B62K23/06 B62M1/10 B62M7/14 B62M11/12 B62H1/12 B62D37/06 

FIELD: transport.

SUBSTANCE: bicycle relates to bicycles with backrests. Turning handlebar 21 about vertical axis 20 allows turning front wheel 4. Inclination of handlebar 21 relative to horizontal axis 17 allows lifting or lowering extra lateral wheels 36. With wheels 36 lowered, bicycle starts and stops. Abrupt lowering of wheels 36 prevents overturn at cross-wind burst. Disks are secured to wheels 36 to engage with rear wheel tire 3. With wheels 36 lifted in downhill, said wheels accumulate energy by means of disks to be given up in climbing to provide for stability due to wheeling and gyro moment.

EFFECT: higher stability at cross-wind burst.
