How to build a pump track! Take 30m3 of clay based silt, 10m3 topsoil and 2 Dingos. Place the basic shape of the track, shaping the berms 1st. This will enable you to line up the rollers and plan how many 'pumps' you can fit in between each berm. HINT! the longer the straights the better because you eventually build enough speed to 'double' two rollers. Place the rollers and compact all the soil well. Take special note in the video footage where the rollers are on the exits of the berms. You need to use the berm to gain speed up the roller and then pump down it for the next straight to hold your momentum. It looks easy but it's actually extremely tiring (and fun though). Make sure you cut the berms quite steep - steeper than you logically think. Cut the berms to suit. Ride and tweek so that you can ride around the whole track without pedalling! See more photos and...

Bicycles and cars on Beijing's Chang'an Avenue during rush hour Photograph: Keren Su/Getty Images/China Span RM After wrestling for years with Beijing's appalling traffic and pollution problems, city planners have come up with a distinctly old-fashioned solution: bicycles. Municipal officials want to boost the number of cyclists by 25% during the next five-year plan, state media reported today. Twenty years ago, four out of five residents in the Chinese capital pedalled to work through one of the world's best systems of bicycle lanes. But the modern passion for cars has made two-wheeled transport so treacherous, dirty and unfashionable that barely a fifth of the population dares to use lanes that are now routinely blocked by parked cars and invaded by vehicles attempting to escape from the jams on the main roads. Last year, China overtook the United States to become the world...

Problems caused by ASRs [boy racers] plagued the inner city a few years ago but these had stopped, due to the inner city's 30km speed limit, the thinning of the roads on Queen St and the increase in pedestrian crossings, Mr MacDonald said. Full article here from NZ Herald.

After five years of sanctioned experimentation in American cities—large and small--the Federal Highway Administration has officially adopted Shared Use Lane Markings, or “Sharrows,” into the latest version of the Manual on Uniform Traffic Control Devices (MUTCD). America Codifies Shared Use Lane Markings (Sharrows) While the MUTCD is not everyday reading for many livable streets advocates, its contents largely dictate how America’s roadways are detailed, signed, and controlled, and therefore controls the widespread application of sustainable transport innovations. Image Credit, Mike Lydon Sharrows are comprised of a bicycle and chevron symbol, which communicate that bicycles and automobiles must share travel lanes equally. First used in the City of Denver, sharrows became more widely recognized following a 2004 study demonstrating that their application in San...
