The utility model content
Technical problem to be solved in the utility model is to provide a kind of for above-mentioned prior art can be easily ride in the harsies environment such as sandstone ground, stair and can not damage the bicycle of wheel nave.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this bicycle, comprise vehicle frame, the front vehicle wheel that is connected with vehicle frame and rear wheel, front tyre is housed on front vehicle wheel, rear tyre is housed on rear wheel, and front tyre comprises front cover tire and the front inner tube of a tyre, and rear tyre comprises rear cover tire and the rear inner tube of a tyre, it is characterized in that: the width of described front cover tire is 3.0～5.0 inches, and the width of described rear cover tire is 3.0～5.0 inches.
Cause car load heavy after the cover tire that uses above-mentioned large width dimensions, the difficulty of riding, wheel hub, the spoke of above-mentioned vehicle frame and wheel are preferably made of lightweight materials such as stainless steel tube or aluminium-alloy pipes.
As preferably, the width of described front cover tire is 3.5～4.5 inches, and the width of described rear cover tire is 3.5～4.5 inches.
Preferred again, the width of described front cover tire is 3.9～4.1 inches, and the width of described rear cover tire is 3.9～4.1 inches.
In order to adapt to different road environments, the bicycle that the utility model provides also comprises speed change system, but the change width due to front cover tire and rear cover tire, the tube outer diameter of making vehicle frame also can correspondingly increase, chain is encountered vehicle frame in the vehicle speed variation process, as improvement, in the utility model in speed change system front group is fixed on the five-way of cycle frame.Existing bicycle, in speed change system front group is generally to be fixed on the middle pipe of cycle frame, under this structure, when the tube outer diameter of vehicle frame becomes large, if front group is continued to be fixed on the middle pipe of cycle frame, bicycle chain in speed-change process just is easy to encounter vehicle frame so.
In order to make driving safer, brake system is installed all on the front vehicle wheel of the bicycle that the utility model provides and rear wheel.
Preferably, the outside face of described front cover tire and rear cover tire is provided with anti-slip veins.
Compared with prior art, the utility model has the advantage of: because the width with front cover tire is made as 3.0～5.0 inches, the width of rear cover tire is made as 3.0～5.0 inches, the front and back tire of this width can be very like a cork ridden and can not damage wheel nave in the harsies environment such as sandstone ground, stair.
