Paris to let cyclists skip red lights | BBC

A man rides a bicycle on the Esplanade du Trocadero in front of the Eiffel tower, on March 11, 2014
Paris plans to triple the number of cyclists in the city by 2020
Cyclists in Paris are to be allowed to ride through red lights after tests showed the move would not lead to accidents.
Traffic lights for bicycles will be placed under the traffic lights for cars on some junctions.
The lights will indicate when bikes can either turn right or ride ahead - even when lights for cars are on red.

Infrastructure vs Helmets

The safest country in the world for cycling is the Netherlands. There you’ll also find the widest spectrum of people cycling: from young children (the average age at which children begin to cycle independently is about 8 years old) to elderly people (those over 65 cycle for over 25% of journeys).
So, the Netherlands is the safest country for cycling at any age, yet helmet use is only 0.5% – and it’s likely that the 1-in-200 helmet-wearing cyclists are riding for sport. Cycling safety is clearly something more than wearing a styrofoam hat – and yet the German ministry for transport is gung-ho for helmets.

All ages and physical abilities, cycling without helmets – yet the safest in the world.
Helmets are no answer to dangers on the street. In the UK, most cyclists wear a helmet, yet cycling there is six times more dangerous than in the Netherlands (and that figure ignores the fact that hardly any children or elderly people cycle there). 
If we genuinely want to make cycling safer, more helmets aren’t the solution. They are really a good indicator that the streets aren’t safe. When people don’t feel safe when cycling, they will wear a helmet – and hi-vis vest – with or without advertising...

Technical FAQ: Minimum tire pressure and more

On minimum tire pressure

Dear Lennard,
I read with interest your reply to Manny with regard to 25mm tyre pressures. I recently purchased 25mm Vittoria Open Corsa SC tyres, and these are clearly marked with “Clincher MIN to MAX pressure: 115 to 145 PSI.” This seems quite unreasonably high to me, so I’m wondering what is a safe minimum pressure to use with 25mm clinchers (would be interesting to hear from your contacts at other tyre manufacturers), and why does Vittoria see the need for such a high minimum pressure?
— Simon
Dear Simon (I sent this answer directly to Simon),
Here is the response to your question from Vittoria:
According to ETRTO, bicycle tires are allowed to deflect 30% of its height at maximum load only. We respect the ETRTO, but we do not limit the body weight of our customers. 115PSI minimum air pressure is the consequence for our high-end 25mm tire with its very flexible casing; the minimum air pressure is related to the worst case: heavy load, rear wheel, aged tire.
We will address this matter more precisely on our MY16 new models.
— Christian Lademann – Product Manager
Vittoria S.p.A.
I’m not going to tell you to do anything differently with your Vittoria tire than Vittoria’s product manager just told you. However, since you’re asking generally what minimum pressure you can with 25mm clinchers in general, I can answer it generally. The safe minimum tire pressure is certainly a function of rider weight, and you’ve not given me yours. I, at 174 pounds, have ridden safely for extended periods on many different 25mm clinchers, both standard clinchers and open tubular clinchers on smooth roads, at as low as 75 psi in the rear and 65 psi in the front. I haven’t measured to see if I get over 30% tire drop at those pressures, but tire squirm is not an issue for me at those pressures...

A Mission for Citi Bike: Recruiting More Female Cyclists | NY Times

When she passes a row of shiny blue Citi Bikes in Manhattan, Yael Steren often wants to stop and take one for a ride. Then the doubt creeps in.
Braving city traffic without a helmet seems too risky. But carrying one around all day would be a hassle.
“I know how crazy the drivers are here,” said Ms. Steren, 36, a personal stylist who lives in Greenwich Village.
Like many women in New York City, she has weighed the wind-in-your-hair joy of urban cycling with the pulse-quickening anxiety of steering between barreling trucks and decided against taking a spin.
When Citi Bike arrived here, it promised to spread the benefits of biking to the masses, an uphill push in a city where large potholes, heedless yellow cabs and darting pedestrians can make riding on busy streets seem like an activity best left for daring messengers.
But two years in, Citi Bike’s inroads have been decidedly uneven, with men far outnumbering women in using the bike-sharing system. A little time on Eighth Avenue on a recent morning, watching the stream of Citi Bike riders heading north past Pennsylvania Station and toward Times Square, was instructive. Man after man pedaled by, some in suits, others in jeans. From time to time, a woman on a Citi Bike rode by.

Opinion: STOP Riding Like This! Ease the Impact of Mountain Biking on the Environment | Singetracks

Enough whining already! Stop berating politicians and land managers for avoiding a fair public process, an absence of bipartisanship, unilateral decisions, dismissing scientific data leading to blind edicts preventing, prohibiting, and pilfering our trails under pretenses that mountain biking harms the environment more than other forms of trail use until…
…we put ourselves under the microscope.

The issue isn’t whether or not mountain biking degrades a trail or impacts the environment in some harmful way, but to what extent it does and how much control YOU have over it. While the impacts of off-road biking have been shown to be equal to (and according to some research, less than) hiking, it is dually important to develop and encourage a certain self-awareness to identify, break, and prevent poor but avoidable riding behaviors to mitigate environmental damage.
