I heard about it last year and couldn’t wait to get my hand on it.

Two recent update on the A-Bike (links below). Quote from the BBC News:

“The inventor who specialises in making miniature objects has a new big idea. A collapsible bike designed to fit a commuter journey as easily as it folds to squeeze into a bag.

The A-Bike weighs 12.5lbs, folds ‘in 10 seconds. Sounds perfect for mixing with MRT.

Named after the shape of its telescopic black-and-silver frame, it claims to come in at half the weight, (12.5lbs) and half the price (£199) of those already on the market. It has two chains, one gear and a weight limit for riders of 13st 5lbs (85kgs).”

But it also mentioned:

“If the bike is meant to fit in to a commute, how does it fare on the Tube itself? It packs neatly into a shoulder bag or can be carried by the handle bars. It is out of the way on the escalator step or the carriage floor, much like any folding bike.

But achy-arm from carrying it is quick to surface, and how everything else would be balanced is less clear. Especially with the amount of gear cyclists tend to trail.”

And Lance Foster, a Bike shop worker gave his verdict:
“the bike is fast, strong and insightful. There is much that he would change: First of all that seat is definitely the most uncomfortable seat I have ever sat on.”Plus, the way those handle-bars fold in – I would have made them a bit longer. With the geometry of the bike you need them for good, aggressive speed. And, when you turn, it is very unstable.”

Pros: light weight (5.5kg), relatively cheap (£199) quick folding, good for indoor use
Cons (tbc): uncomfortable seat, wheels may be too small for Singapore road condition
