This bicycle is a minivelo based on 16-inch wheel.
The core of the design is that the main frame is T-shaped. This T-shaped frame makes this bicycle easy to fold and unfold. The folding of central shaft frame is followed by gear shaft, rear wheel shaft, and front wheel shaft and folding the gear shaft makes rear and front wheel fold simultaneously. This unique design makes the folding-time short.(time required : 5 to 7 seconds)
T-shaped frame also gives another advantage that rear part has a storage cart.
Out of handle-saddle consisting linear frame, the saddle-consisting frame can be folded 90 degrees downward to make it small.
Connecting part between handle-shaft and front wheel frame is arch-shape designed which gives it more sporty frame design than conventional bicycle. Also it makes the folding of the bicycle possible.
In a conventional bicycle, front-wheel handle-shaft is equipped with shock absorber to absorb impact. However, in this bicycle, the shock absorber is equipped in T-shaped frame where front-wheel shaft and rear-wheel join and the shock during ride can be absorbed with the entire bicycle body to give more comfortable ride.
Frame from front and rear wheel shaft is equipped with light-weight plastic parts to make the design components of the bicycle more valuable. Also it is designed to install a battery to make is electric bicycle.
The front and rear wheel can be folded half which is 50% and the folded bicycle is easy to move and change directions in a certain degree.
Outlook view of design is that the bicycle shows new sporty T-shaped frame out of conventional bicycle frame and this frame makes easy and quick folding possible.
