Distinctively designed, it attracted plenty of curiosity when we rode it in public. It's a simple and stripped-down bike with a steady ride coming from the single gear, which makes it better suited to short hops than longer journeys. A clever feature is the Kevlar belt chain, which as a result of being oil-less won't spoil trouser legs or car interiors. But unclear instructions made this more of a hassle to pack away than it should have been.

The build quality is excellent and clips provide easy seat and handlebar adjustment, but that's where the plus points end. The gears didn't work on our test model, but that didn't affect the fact that we felt quite unstable riding this, perched high above the frame and wheels. And the aesthetics are less man about town and more gran about grocers.

Has the vague air of a shopper cycle about it, the gears are slightly jumpy and it's not as nippy as the Airframe, but ride it for a while and it impresses. It's sturdily built, deceptively fast once on the move and comes with dynamo lights, pump and bell to terrorise wayward pedestrians. It fulfils its folding brief well - there are no screws to undo, it just folds into an impressively compact shape with the minimum of fuss.

Everything about this model, from the sharp styling to the Shimano gears and brakes, marks it out as a quality bike in its own right, that has the added benefit of being foldable. The ride is smooth and fast and the many gears make it suitable for all types of conditions and gradients. The only drawbacks are the price and the fact that it doesn't fold as simply and conveniently as some of the others.

Earns marks for its sleek but unusual aesthetics and light weight. On the road it gives a reassuringly stable ride, with good grip shift gears and nimble handling - it feels as if it would be handy nipping in and out of traffic. On the down side, the brakes felt a bit squishy and even when folded it remains a long package that might not be easily stored.
