The trifold folding bike,20inch(406) for Rolling Japan

Описание: *Apology and Correction: "In the video, the 20inch (405) is shown as 20inch (406), but this is a mistake.

I got a chromoly trifold folding mini-velo 20" for a long ride.
In Asia, where Brompton clone bicycles are very popular, we can choose the frame and basic parts of a trifold folding bicycle that is the same design as Brompton, as well as various other parts that are available in the factory version, and assemble the bicycle to the desired specifications.
In addition, because Shimano parts can be used for the external transmission and sprockets, we were able to assemble and obtain a 20inch(406) mini-velo bicycle with a chromoly frame that folds compactly.

It has 20inch(406) aluminum wheels, Shimano external rear derailer, Tiagra 10-speed, and the same trifold folding design as the chromoly-framed bike.
It is a popular folding bicycle model.

When I ride this bike, I have found that it has a long wheelbase, a stable ride, a rigid frame, and a well-made bicycle that moves forward when I step on it, without any strange flexing or squeaking.

Replacing pedals, tires, and other parts will improve the ride.
I think it is a bicycle with a cost performance that is satisfactory enough to travel around Japan.

With 20-inch wheels, it is easy to maintain a cruising speed of about 28 km/h. With 16-inch wheels, it is easy to maintain a speed of 25 km/h but a bit tough to maintain a speed of 28 km/h.
I can go a little faster in cruising speed, because of the increased wheel length,

The front chainring and rear sprocket work well with best matching, and I do not feel the need to change gears at all.
The cruising speed has definitely increased and I can easily do a 28 km/h cruise.
