Description

The structure of big steamboat Collapsible bicycle

Technical field

The utility model relates to the structure of big steamboat Collapsible bicycle, particularly relevant for big small-wheel bicycle that can simple and easy fast folding, the speed that not only drives is identical with Regular Bicycle, and cost is low, folding combination is easy fast, the structure of the big steamboat Collapsible bicycle that volume is little, easy to carry.

Background technology

Commonly use the front-wheel of Folding Bicycle and the wheel that trailing wheel all is to use little wheel diameter now, though portability, when driving, speed is but significantly slack-off, so that the knight must expend more muscle power and time when driving, reality has many disappearances and can't break through.

Therefore, this creator is studied intensively in R﹠D process meticulously, probe into, create more excellent part, and constantly row innovation again, break through tradition, researched and developed, it specifies as follows: the conventional foldable bicycle is all because will reduce bicycle single-piece volume, to such an extent as to before inciting somebody to action, the diameter of latter two wheel reduces, the diameter of its wheel sometimes even the size of a little semidiameter to original wheel, yet, these Collapsible bicycles make the relative minimizing of speed of its rotation over half because have the specification of minor diameter wheel, cause the bicycle knight must waste more time and muscle power when driving; In addition, the structure of the bicycle folding of conventional foldable is quite complicated, make the buyer not only need to waste considerable time when folding folding, more improved the manufacturing cost of bicycle, and its complicated structure has more increased bicycle single-piece weight, causes bicycle knight inconvenience greatly and puzzlement.

More than these disappearances promptly be the long-term fraud that lacks that various traditional folding bicycles can't be broken through.

The utility model content
