Phillip Young writes today with a brilliant DIY workaround for the problem of carbon wheels not being recognized by traffic signal sensors.
Would you please pass this traffic light safety tip along to your readers with carbon rim wheels?
Carbon rim bicycle wheels usually do not trigger traffic signal light sensor coils buried in the pavement and can be a safety issue. The non-conducting carbon rims do not change the magnet field around sensor coils, so the traffic light doesn’t change for you.
If the traffic signal light doesn’t trip in your travel direction and you have waited for 2 or 3 minutes, you may be inclined to run the red traffic signal light dodging traffic at your peril.
My carbon rim bicycle wheels would not trigger traffic light sensor coils buried in the pavement until aluminum foil tape was applied to the rim circumference with some foil tape overlap.
I added 3M adhesive backed aluminum foil tape cut about the width of rim tape where the normal cloth rim tape goes. The adhesive backed aluminum foil tape sticks well to the carbon rim material and weighs almost nothing. This should work on all carbon rims using inner tubes.
Push the aluminum foil tape down against the rim to get full contact and adhesion. Install the normal cloth rim tape on top of the aluminum foil tape. The foil tape also offers additional support to the rim tape over the rim spoke holes.
The rim with aluminum foil tape now reliably triggers traffic light sensor coils. The bicycle wheel rim with aluminum foil should be positioned parallel to and directly over the sensor coils buried in the pavement rewarding you with a green light.
May your travels be safe and green lights will always be with you,
PS: Aluminum rim bicycle wheels usually work triggering traffic signal lights if the wheel is positioned parallel to and directly over the pavement sensor coils.
For those looking for a more detailed explanation of why this works, Young followed up with this post from Cyclelicious.
Nextdoor users have been reporting a possible bicycling fatality Monday morning on Dover Drive near PCH in Newport Beach.
So far, though, I’ve been unable to find any confirmation. So let’s hope that Nextdoor, which is not exactly known for its veracity, is wrong this time.
Thanks to David Huntsman and Lois for the heads-up.

A crowdfunding campaign to help the victims of Saturday’s vehicular attack at a master’s bike race in Show Low, Arizona has raised nearly $60,000 of the $100,000 goal.
Which works out to just $10,000 for each of the critically injured victims.

Nothing like heading out for a McDonald’s run with a tandem bike-powered car.
The war on cars may be a myth, but the war on bikes just keeps on going.
No bias here. After a California man was killed when he struck a chain blocking a Carson City, Nevada trail, the local sheriff warns against riders over-extending their confidence levels, instead of warning about dangerous chains strung across pathways that can kill unsuspecting people on bicycles.
Pennsylvania police are looking for the hit-and-run driver who sideswiped at least five bike riders with his passenger side mirror; the victims believe it was a deliberate attempt to buzz, if not injure, the riders.
Los Angeles received an $18 million grant for safety improvements to the Broadway corridor in South Los Angeles, rather than the $64 million the city asked for, on the condition that they limit the project to the safe street infrastructure component of the application for the deadly street, and guarantee completion; the street is one of LA’s most dangerous streets for bike riders and pedestrians.
