If you thought propellers were just for old planes and geeky hats, then you might want to think again. Take one MIT student, Damon Vander Lind, one three-wheeler made from chromemoly tubing and one bloody large propeller and strap them all together to make an eco-friendly fan-propelled and pedal-powered trike.

Toward the end of last month there was a very special 25th birthday: on the 23rd April 1982 the Sinclair ZX Spectrum was launched on an unsuspecting British public. Here in the UK Sir Clive, the founder of Sinclair, became something of a figure of fun after the failure of his C5 personal transportation machine (a swish name for an electrically-assisted recumbent tricycle), a 1985 effort to tackle urban transport, and few are aware that his research - and the marketed results of it - continues to this day. A chance link from a ZX feature led me to Mayhem UK, official distributors of the latest Sinclair product, the folding A-Bike.
It's been quite a few years since I've rode a bike, and any desire to do so now would be complicated by not actually having one any more. The cash-injected biking industry does me no favours when it comes to choosing one, either, with all manner of complicated variations in gears, brakes and chassis; stepping into a specialist bike shop is about as scary as browsing a designer clothes store, under the disapproving and contemptuous gaze of the assistants.
Gear manufacturer Shimano has obviously decided to cash in on that eco-concerned but bike-ignorant market sector, and the Coasting system is their first strike. Basically a three-speed automatic transmission for a bike, it takes all the complicated "first you flick this lever, then that one, but never stop pedalling while you do it!" madness out of the whole business.
