A-bike - the world's most compact and lightest folding bike - by Sir Clive Sinclair

-
So named, because of its ‘A’ like shape, the uniquely styled A-bike feels much like a normal bike to ride, however, unlike other folding bikes it can easily be slipped into bag while you hop on the tube, train, bus, or even a plane. A-bike is half the weight, half the size & half the price of any other folding bike!
Sir Clive explains “The principle use for the A-bike is city or town travel over relatively short journeys but also very much for mixed-mode journeys where you’re hopping on and off a bus or a train. For example a typical commuter needs to get from home to local station and then from destination to his or her office – and all without any worries about portability, parking or security.”
“The key to its successful introduction,” adds chief designer, Alex Kalogroulis, “is an entirely fresh approach to the main challenge: how to minimise weight and optimise foldability while retaining full functionality. At the heart of the solution are light, highly-reliable telescopic tubes coupled with telescoping brake cables."
Despite the wheels small size, the use of a dynamically geared twin chain system enables users to pedal normally and retain their balance. The high performance 90psi pneumatic tyres allow for a smooth and comfortable ride on most hard surfaces. The wheel size a key factor in making the bike so lightweight and compact.

The internal twin chain system is totally encased at the rear of the A-bike which has the benefit of keeping grease and dirt away from clothes and hands. The A-bike has a single, easy to use, gear transmission.

A-bike is designed to be folded and unfolded in less than 10 seconds with a 3 click telescopic mechanism to a folded size just 67 x 30 x 16cm.

Technical Specification

Frame Materials
Heat treated aluminum and high strength glass fibre reinforced engineering polymer constitute the majority of the frame.

The twin chain gearing system specifically uses small drive axles, often one of the heaviest parts of a traditional bicycle. Pedal cadence remains the same as a normal
Wheels
Each wheel weighs only 350g and this includes the pneumatic tyres which give such a smooth and comfortable ride.
Brakes
Designed specifically for the A-bike, the semi circular band brakes fit the wheel perfectly providing a lightweight and robust alternative to traditional shoe brakes.

The Holy Trinity: Perfumes Made by Monks

The rarefied aura that surrounds fragrance dates back to the remotest times of antiquity, when incense and fragrant oils would be offered up to the gods and deities of the ancient world. The Arab world is credited with introducing modern perfumery to the West, having preserved the ancient arts of distillation, evaporation, and filtration that had been lost to Christian society, and in turn heralding great advancements not only in the field of fragrance but of chemistry and science too. In passing this tradition on, Christian monks began to adopt the practice of creating fragrances as an expression of faith, before eventually the art form became available to the wider public, for a price. Today, most perfume is manufactured on a grand commercial scale; a far cry from the artisanal monastic traditions that gave birth to modern fragrance! However, some perfume houses still survive from this bygone age and serve to remind us of our industry’s history while continui...

Bâtard Folding Picnic Knife by Lamson & Goodnow

As author of The Best Bread Ever; Charles Van Over is expected to show everywhere up with an armful of bread. Whilst Charles enjoys breaking bread with friends; he does insist that the bread is properly sliced with a breadknife, not just ripped apart. The problem here is that bread knives are very long and with their serrated edges they are not the easiest of things to carry around. Charles wondered why a folding bread knife could not be produced and took his idea for a pocket bread knife to Lamson & Goodnow, American manufacturers of the LamsonSharp range. The Bâtard Folding Picnic knife is the result of this collaboration. At Roullier White we believe this may possibly be the best picnic knife ever made. The French word bâtard – and yes it does translate how you think it does – is a shorter and thicker type of baguette. The knife, of course, will cut everything including cheese, fruit, vegetables and as you cannot have a picnic without wine it also has an integral corkscrew. Rou...
