Auto ban: How Hamburg is taking cars off the road

Source: The Independent. 15th of January 2014. For a country which prides itself on having given the world the Mercedes and the Autobahn, it represents a major ideological U-turn: Hamburg, Germany’s second largest city, is planning to ban all cars from its centre over the next 20 years and put thousands of commuters on bikes. “We envision a network that doesn’t just help residents to get from point A to B in a sustainable fashion,” Hamburg city spokeswoman Angelika Fritsch told the ZME Science urban planning network. “It will offer people opportunities to hike, swim, do water sports, enjoy picnics,… Read more →

Cyclists make up a quarter of London traffic, official census finds

London cyclists have long suspected that there were far more riders on the streets of the capital than the authorities gave credit for, and new figures from Transport for London finally confirm it, with cyclists a staggering 64 percent of peak hour traffic on one road. The Evening Standard reports that a new census of cycling in London has found that one in four road users in the morning rush hour is a cyclist, and that the proportion is even higher on some popular routes. Theobalds Road, Holborn takes the gong as London’s most bike-trafficked street, with bikes making up… Read more →

Ridgeback: Scoot 12” Balance Bike Series

Freshly updated for 2025 is the celebrated 12” balance bike series from Ridgeback. Featuring a robust yet light frame for ease of learning, a rear brake and a bell, these will help your little ones to scoot around within moments! Balance bikes are much easier for kiddos to learn with than the hefty stabiliser versions of yesteryear: they begin by walking over the bike, then as their confidence grows they’ll raise their feets off the ground and then roll along. This alleviates the awkward stage of capsizing when stabilisers are removed, because they learn to balance instead of leaning on… Read more →

Battery Pack, Charger and Cradle Combo

Whether you’re giving an existing bike a new lease of life or building a Hotrod, the same key considerations apply: • The more capable your battery pack, the more you’ll get out of it between charges • A pack run mainly between 20-80% of capacity will last much longer Batteries have come a long way over the last few years, albeit with almost all packs using a few dozen rechargeable cells similar to ‘AA’ batteries inside. Choosing which pack fits an existing bike is a little more complicated, so our Combo packs include the charger and the battery’s mounting cradle,… Read more →

Augmented Riding: infinitely more fun?

Evolution has gone hand in hand with humankind augmenting ourselves. We have progressed from a leaf to protect one’s modesty, to wearing skins and heavy shoes, the monocle, past air-filled trainers, to VR headsets and glasses, sub cutaneous sensors and beyond. Bicycles have progressed too, yet vast swathes of society struggle to see augmented riding as a natural progression: taking what we have into overdrive and making it more fun in the process. ‘Hills and thrills’ perhaps? Digital bikes are to the bicycle what digital watches are to their analogue/wind-up cousins: augmented by the very best of what technology can… 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 →

Major trauma and urban cyclists: physiological status and injury profile.

Barts Health and St Paul’s skyline. At the Barts Charity Seminar on the 31st January 2014 delegates were asked the following question: “Can advances in medicine and research at Barts Health impact the number of killed or seriously injured people from cycling incidents?” Personal safety is a common concern to all cyclists, especially whilst commuting through our city’s streets. What’s less common is the opportunity to meet and discuss public health and care of trauma patients with the surgeons, doctors and health professionals who look after us all. The delegation brought a wealth of knowledge, from injured cyclists describing their… Read more →

Expensive cars and driving psychology

A Range Rover obstructing an ASL. Source: The Peeky Rider. http://hedgehogcycling.co.uk/ 20th November 2013. “I was crossing the road at the same time as a pretty, young, blonde girl to the pedestrian refuge in the middle, then to the other side, crossing two lanes of traffic each time. All the drivers stopped and waved us (her), across. When it’s just me, this doesn’t happen. I watched an expensive Mercedes glide right into an Advanced Stop Zone reserved for cyclists, and come to a halt at the second line. Typical of a Mercedes driver, I thought. I’d think the same if… Read more →

Cycling Census Data: 2001 versus 2011

A car recycling area and scrap yard. Census data is absolutely undeniable: there have been massive rises in car-free households here over the past decade. It is now officially the majority-case all across London. Yet London’s borough councils persist in designing our roads for cars rather than for pedestrians, bikes and public transport, in direct conflict with what’s actually happening. Some examples: Kensington & Chelsea households are now 56% car-free, up from 51% in 2001. In Hackney, it’s more dramatic: 65% of households are now car-free, up from 56% in 2001. Lambeth: 58% of households are car-free, up from 51%… Read more →

Flying Bicycle

A Canadian-built helicopter that is powered by a human riding a bicycle has become the first winner of a decades-old $250,000 (£165,000) engineering prize. The American Helicopter Society had never given out its Igor Sikorsky Human-Powered Helicopter Award – initiated 33 years ago – until the team from the University of Toronto won it this week. The challenge was to create a flying machine that would be able to reach a height of three metres, fly for 60 seconds by human power alone, and stay within a 10m by 10m radius. “It was long seen as impossible to win this,”… Read more →
