Problems solved by technology
[0002] Most of the folding bicycles in the prior art use a hinge in the middle of the girder, and the bicycle is divided into two parts, the front and the rear, and folded together through the hinge. The disadvantages in actual use are that it is bulky and inconvenient to carry.
Also have, the folding bicycle of prior art adopts the drive structure of small wheel and common bicycle pedal sprocket to drive rear wheel flywheel more, because the radius of small wheel is little, adopts the drive structure of common pedal sprocket and rear wheel flywheel to make riding Riders cannot increase their speed like ordinary bicycles, so it is very difficult to drive

The invention provides a telescopic, foldable and portable bicycle, which comprises a handle bar folding mechanism, a girder telescopic and folding mechanism, a seat telescopic and folding mechanism, a rear wheel folding mechanism and a two-level sprocket driving mechanism, wherein, the handle bar folding mechanism is arranged at a front part of the girder telescopic and folding mechanism; the rear wheel folding mechanism is arranged at the back part of the girder folding mechanism; an acceleration mechanism with two gear levels is arranged between the rear wheel folding mechanism and the girder telescopic mechanism. Compared with the prior art, the telescopic, foldable and portable bicycle is characterized by reasonable design, simple structure, safety and reliability, convenient utilization, small size, easy carrying, etc., thereby having great popularization and utilization value.
Description
1. Background technology [0001] The invention relates to a vehicle, in particular to a telescopic and foldable portable bicycle. 2. Background technology [0002] Most of the folding bicycles in the prior art adopt a hinge in the middle of the girder, and the bicycle is divided into two parts, the front and the rear, and folded together through the hinge. The disadvantages in actual use are that the bicycle is bulky and inconvenient to carry. Also have, the folding bicycle of prior art adopts the drive structure of small wheel and common bicycle pedal sprocket to drive rear wheel flywheel more, because the radius of small wheel is little, adopts the drive structure of common pedal sprocket and rear wheel flywheel to make riding Riders can't increase their speed like riding a normal bicycle, so it's very hard to drive. 3. Contents of the invention [0003] The purpose of the present invention is to provide a telescopic folding portable bicycle with simple structure, conven...
