Description
Technical field
The present invention relates to a kind of bicycle, especially foldable multimode list two-wheel variable limit sports bicycle.
Background technique
The type of existing bicycle includes several major class such as scheduled bus, folded bicycle, mountain bike and extreme sport bicycle.Commuting
Vehicle has simple appearance, rides instead of walk use for daily life；Folded bicycle has the mechanical structure that can be folded, and can be realized folding
It places, it is easy to carry；Mountain bike can satisfy the demand of different terrain；Extreme sport bicycle is able to satisfy various technical movements
Demand carries out extreme sport.Existing wheelbarrow is applied rides instead of walk, in stunt movements daily, it is with small in size, portable etc. excellent
Point is deep to be liked by young friend.Existing extreme sport bicycle is many kinds of, compact structure.But they it is shared the disadvantage is that:
The function of bicycle and wheelbarrow is excessively single, and structure fixation is unchanged, one for outdoor sportsmen extensive for interest
Bicycle or a wheelbarrow can no longer meet its requirement.
And existing bicycle substantially using rim brake brake and chain transmitting power by the way of, bicycle using for a period of time
Afterwards, rim brake will appear insensitive phenomenon, be easy to cause accident；When using bicycle, it may appear that the case where chain-taking, sometimes
The lubricating oil on chain can be also stained with by waiting divided skirt.
Summary of the invention
The object of the present invention is to provide a kind of foldable multimode list two-wheels can be changed bicycle, and the present invention can conduct
The bicycle of two-wheel mode uses, and can use as the bicycle of single-wheel mode, while can be freely disassembled assembling and meet not
Same requirement, had not only had the daily function of riding instead of walk, but also meet the hobby demand of outdoor enthusiast, easy to carry.
Technical solution of the present invention: a kind of variable bicycle of foldable multimode list two-wheel, including vehicle seat and handlebar, vehicle seat
