自転車は、知らないうちに密かに進化し続けている。
「自転車は未来の乗り物」と言ったのは、高崎の自転車工房CYCLETECH-IKDの店主の言葉。名言である。（我が家のバイクフライデーtikitはこちらでゲットした）

以下の動画に注目。この駆動輪の後輪にハブの無い自転車、発想がおもしろい。こういう発想は大切にしたい。これはプロトタイプ。これからまだ進化を続けるだろう。
前輪を後輪の内部にスッポリ収容する折りたたむようにすればコンパクトな折り畳自転車ができそう。

Lunartic is a Loughborough University Design and Technology final year project by Luke Douglas.
The aim was to use a hubless wheel to create a compact bicycle, with the benefits of a large wheel and belt drive.
Hubless wheels have appeared in bicycle concepts already, and were first invented by Sbarro. However, few concepts have made it to prototype and when only used for aesthetic purposes, the disadvantage of extra cost out weights the visual gain. Lunartic uses the hubless for a reason; to house the working parts, reducing the wheel base but not sacrificing conventional riding geometry.
Lunartic is supposed to be as compact as possible without folding or being awkward to ride, however there is the potential for the front wheel to fold up into the rear or for that space to be used for a laptop back, motor or dynamo.
This first prototype proves the unique theory behind the design but will require further development before being ready for mass manufacture.
Great design, but you could remove the belt drive and just use planetary gears in the hub. which also means you could have gears of what ratio is up to you or use a CVT like in cars.
