I have searched for A-Bike on taobao.com.
For what I have understood those companies in the Zhejiang province are now selling 8” and 6” wheeled A-Bikes.
Interestingly I have noticed that they are now offering also PU wheels. By my experience PU wheels, even though less comfortable, offer reduced rolling friction. I am sure that this addition will be appreciated by people living in towns with smooth surface. If the PU is good, then the bike might actually turn out to be pretty fast.
It is a while that I am working on a portable bicycle that uses also inline skate wheels (Mini125RD).
Actually I am designing it right now. I was willing to post my two cents about mini small wheels (below 8”), but I am too busy designing and building all of this stuff….
By the way, for what I have seen, Chinese bicycle prices have stabilized again. Corrected 11th 5 year plan or not those A-Bike are going to cost in China ex-works 10 times less the my ex-works cost here in Italy. I guess I have to wait for the 12th 5 year plan.
Maybe this link works:
