June 26, 2006 Fold-up bikes are certainly not new though none to date have deserved the moniker “portable”. Most use the same heavy chain sets and bulky 16 to 20 inch wheels and traditional materials and are at best luggable. The A-Bike is a folding pushbike that is claimed to be small enough so that you can take it on public transport with a no-bicycles policy. The US$300 A-bike utilises automotive grade, engineering polymers for its structural components, saddle and handlebars and has a level of stiffness, fatigue and impact resistance comparable with aero-grade aluminium. By using these new materials, the A-bike’s weight has been reduced to just 5.5 kg (12 lbs), which is manageable for even slightly-built individuals. Whatsmore, it can be folded inside 10 seconds into a compact 26” x 12” x 6” (66 x 30 x 15 cm) package and has pneumatic tyres, so riding it will not dislodge the fillings in your teeth. In our opinion, the A-Bike looks to be the first viable foldable bike for those who wish to mix modes of transport and we see it as invaluable for yachts and motorhomes and campers where a simple vehicle for short-distances is a boon but storage space is limited.
