A few sources suggest that mounting a foam pool noodle on the back of your bike can help stop drivers from passing too closely. Such noodles are available at my dollar store, unlike spring-loaded bike safety flags.

See [photo.](http://www.facebook.com/photo.php?fbid=10201052555424987)

But I fear that both the flags and the noodles may be illegal.

Anyway. I am considering carving such a noodle so that its tip tapers to a "sharp"-looking point. (Pool noodles are hollow. I guess I would carve the noodle asymmetrically.) I would mount it like in the photo, except that I would have it stick out less: only a couple feet (30-50 cm) towards overtaking traffic. I'm not sure how I would mount it on the bicycle. Maybe I'd use a bungee cord.

  1. Still, imagine that a sadistic driver used his car to push the carved point towards the edge of the road. I'm no physicist, and am not sure what might happen to my moving bicycle. What are the possible outcomes? (Note that if the noodle was illegal, and if my entire bike was damaged, I might not even be able to get compensation.)

  2. (Optional:) Also, in general, do you think it'd be safe for me to mount such a noodle on my bicycle?

  3. (Optional:) Do you have any alternative suggestions which are still frugal, but are more safe?

  • Why exactly does the pool noodle need to be carved into a pointy pool needle?

    If a sadistic driver is 2 feet from you using the noodle to push you off the road, the least of your concerns is the noodle pushing your bike to the side. If that's really a concern, mount the noodle with a single layer of tape that will break off under pressure, or mount it in a piece of PVC pipe that would let the noodle move to the side.

  • @amcnabb: If I didn't carve it, then a sadistic driver could push the noodle to the side. I don't know what effects that would have on a moving bike. Jun 13, 2013 at 22:43

Your question really seems to boil down to:

  1. Is using such a noodle illegal?
  2. What are possible outcomes if a driver still passes me too close?

My answers to this;

  1. We don't know. This is something that most likely will be dependent on the laws of your country. So I would suggest you to find out something about "allowed transport techniques on a bicycle" where you live.
  2. Possible outcomes are from nothing happens to an accident with the car.

I can understand that you are scared that a car has passed you so closely and that you want to do everything so this never happens again. This will not be possible. Some car drivers will always try to pass you. I have seen car drivers who drove up onto the sidewalk or onto an elevated tramway just to pass me.

Think about the question of an angry driver: "How can I pass a bicycle which is very broad/in the middle of the road/...?"

  • +1 and accepted. Good points. Still, I think that attaching something to my bike might help. Maybe I'll attach a (washable) black marker pen to the end of a noodle. Some angry drivers might not be scared of the noodle. But they might be scared of the marker, and might leave me some space. (Unless their car is black.) Jun 21, 2013 at 23:45

The three-foot extension noodle is absolutely obnoxious and a genuine safety hazard (for starters, how is another cyclist supposed to safely pass her?).

The original point of these noodles, as I've seen them, is to cut one as wide as the widest part of your bike so cars could better gauge how much distance they needed to pass you. Perspective distortion and the small width of handlebars can make it less obvious to a driver how wide your handlebars actually are, and the neon color is to accentuate the visibility.

If you cut the noodle to the width of the widest part of your bike, you don't have to worry about someone using it to push you. You also shouldn't bother "sharpening" it, because the point is to indicate "Here's how wide I actually am". If anything, you'd want to square off the ends so it looked more like a |----| shape to accentuate the dimensionality of it.

Cut to the proper size, it's also very unlikely to be considered illegal as it's not materially changing the effective dimensions of your bike.

  • Thank you for your answer Ryan. I want an extension noodle because I want all drivers, even angry drivers, to leave me at least six inches (15 cm) of space when they pass. Preferably more. If a driver is angry that I'm on the road at all, then a handlebar-sized noodle won't force them to leave six inches. So I don't want a gigantic-extension noodle, but I don't want a non-extension noodle either. Jun 14, 2013 at 0:35

    I'd be surprised if drivers are passing you with only 6 inches to spare - their mirrors should be slapping you on the elbows if that were the case (and you'd have a good case to report them for hit-and-run). If a driver is aggressive enough to pass you that closely, I'd be surprised if any flexible attachment on your bike will make them behave any better and if they are angry because you're on the road, they'll be even angrier if you make your bike wider than it needs to be.

  • @Johnny: It's only ever happened once that I recall, a couple of days ago. Their mirror didn't touch my elbows, but it came within a few inches of my handlebar. Also, note that a safety flag made of hard plastic would indeed help: as Anaheim pointed out above, drivers avoid doing things that will scratch their car. Jun 21, 2013 at 23:34

Oh my! That is my picture & I never had any trouble hitting pedestrians since the noodle only points into traffic & away from the sidewalk. There was not a lot of bicycle traffic on the road, but cyclists had plenty of room to pass me in the same lane. No car ever tried to hit my noodle, but maybe where you live the driver's are more aggressive. The noodle represents the 3 feet of berth that a car is legally supposed to give in my state, so if they can't pass without hitting the noodle they are breaking the law. The noodle bends so unless someone drives around the noodle and then bears in on you, the noodle will bend out of the way & not push you. Again no car ever braved hitting the noodle where I was. This is not meant to stop cars from passing, but it does force them to wait for a safe place to pass.

I'll attempt the first question "Is a pool noodle illegal?" It depends on the country. In Germany (and probably similar in most EU) the vehicle regulation code (StVZO) does not explicitly prescribe dimensions for bicycles, but the general opinion seems to be that the rules for small motorbikes (mopeds) apply (StVZO paragraph 32). This means a maximum width of 1 metre for the bike and also for trailers. This is also what I was told a couple of years ago when I inquired about building my own bicycle trailer.

Load dimensions are in paragraph 22 of the traffic code (StVO). If a load (on any vehicle, as far as I understand) extends sideways by more than 40 cm beyond the shape of the vehicle, it has to be made visible with flags and lights. Vehicles with loads cannot be wider than 2.55 metre in total (exceptions for agricultural vehicles).

The rule specifically says that poles, sticks, flat boards or similar should never extend sideways (I think this means more than 40cm beyond the vehicle contour). Presumably the idea is that they are very hard to see as they have a small contour. They probably didn't have soft foam noodles in mind, but technically these noodles are "poles or sticks"..

What I take from that is: If you fix the noodle in some kind of permanent way, then it's part of the bike and the bike should not be more than 1 metre wide in total. So you can probably only have it stick out about 30-40cm beyond your handle bars (ca 60cm wide). If it's attached loosely, then it counts as a load, but still has to be less than 40cm as it is a "thin pole or stick"

As the noodle is soft and not really a danger, you will probably not be prosecuted but I would expect police will stop you and ask you to remove it if it sticks out more than half a metre.


do you think it'd be safe for me to mount such a noodle on my bicycle

No. You will slap pedestrians' butts and children's faces with it.

  • -1. I wrote above: "I would have it stick out less: only a couple feet (30-50 cm) towards overtaking traffic." To clarify: I would not make it stick out towards the sidewalk at all. Oct 31, 2013 at 5:09
