Tannus: Aither (puncture-proof, solid bike tyre)

Tired of punctures? You’re not alone! The team over at Tannus have just released the world’s first accessible, puncture-proof tyres. Read the review on The Telegraph here.

Transport

Electric Bikes: It’s not Cheating, it’s Transport A bicycle used for the sole purpose of getting from A-B, is ‘Transport’. Priorities include an upright riding position, day-to-day practicality and suitable pricing. These models are destined to spend a lot of time chained up in public areas. Reliability is crucial and this includes relying on the bike to be wherever you leave it, 100% of the time. The electric bicycle has finally come of age. Battery technology is now truly affordable and ‘Pedelecs’ are a pleasure to go considerable distances on without breaking a sweat. As you pedal, they contribute a… Read more →

City Cycling: Health Versus Hazard? Cities Compared Internationally.

© Sarah Maycock/Handsome Frank http://mosaicscience.com/story/city-cycling-health-versus-hazard Are the fitness benefits of riding your bike worth the risk of an accident? Lesley Evans Ogden takes a tour of seven cities on two wheels to find out. It was just another morning commute. That is, until a bus driver ran a red light, turned right, and drove straight into Ann-Doerthe Hass Jensen. The bus knocked the social worker off her bike, trapping her underneath, a wheel pinning down and crushing her left foot. It was a school bus heading to a Copenhagen kindergarten, and the children aboard were screaming. Ann was rushed to… Read more →

Henry Ford, Thomas Edison and the Cheap EV That Almost Was.

That Henry Ford and Thomas Edison were good friends late in their lives is well-known. They camped together, presented each other with lavish gifts, even owned homes adjacent to each other. Many Ford enthusiasts also know Ford, when he first drove his Quadricycle on the streets of Detroit in 1896, worked for Edison at Detroit Edison Illuminating Company. And historians know Edison, when introduced to Ford some months later and shown Ford’s plans for a gasoline automobile, encouraged the budding industrialist to pursue those plans. What is far less known is Edison and Ford worked together on an affordable electric… Read more →

Thomas Edison & Henry Ford’s Electric Cars

Photograph courtesy Thomas Edison NHP, NPS/DOI. To inventor Thomas Edison in the early 1900s, electric cars looked like the future of transportation. Although better known for inventions such as the light bulb and motion pictures, Edison also designed three electric cars using his nickel-iron Edison Storage Batteries. Here he is seen standing beside a model that left New York on a 1,000-mile promotional “ideal tour” in September 1910, charging along the way and ending with an ascent up New Hampshire’s Mount Washington. By the time Edison’s battery (a longer-lasting, lighter-weight improvement over previous lead-acid batteries) was ready for this journey,… Read more →

Electric Bikes: It’s not Cheating, it’s Transport.

Steve McQueen owned the predecessor of our 2012 Pininfarina-designed Velosolex. Before the tyres were even pumped-up on our new ‘pedelec‘, two road racers appeared. One observed that it was electric and the other, that it was cheating… and so began the debate: are electric bicycles ‘cheating’? For those unfamiliar with the term, a pedelec is a bicycle with regular pedals plus a battery and motor. As you pedal, the motor adds a little assistance. When you stop pedalling, the assistance stops. It won’t drive on battery power alone: you have to make the effort to reap the rewards. They don’t… Read more →
