Clive Sinclair never learns. Yet again he has come up with an interesting idea, but hasn't researched the market and the existing offerings. This pseudo pushchair with ambitions will be just as successful as the Zike or the C5.
There are already folding bikes that can be taken on trains (Brompton, Molton, Bike Friday and others) which are much better to ride and can carry more baggage than the A-bike. Those tiny pushchair size wheels are going to get stuck in the first pothole and pitch the rider over the handlebars. People who don't already cycle commute are very hard to tempt into trying it; the A-Bike should do better than the Segway because it's a lot cheaper, but its practical range will be very restricted.
