I must say my bike isn't 3m long let alone wide.

The actual question and what it is trying to get at are different things, it seems. Not a helpful approach to this more literal person but each to their own.

There is all the difference in the world between a cyclist negotiating a narrow gap and a motorist passing a moving cyclist with enough energy to kill the cyclist several times over.

Anyone equating the two is an idiot

Sadly I wasn't equating the two. I was pointing out that if you genuinely think a bike is 3 metres wide you are going to end up in some funny situations on the road because it seems this isn't a question about how much room to give a cyclist. Clearly it is about how wide a bike is.... apparently



Not sadly at all. I’m glad to hear it.

A bike might be “440mm wide”, but no one sane would cycle through a gap that small, traditionally a bike has been considered to be between 3 and 4 feet wide due to the dynamic width required to keep the black bits pointing down - combined of course with the width of the riders (a quick and dirty measurement of my shoulders puts this rider over 50cm wide, making the bike widths quoted above a bit pointless).
At lower speeds that dynamic width increases (unless you are Danny Macaskill).

However the true width of a bike as perceived by anyone less vulnerable than the rider should be the traffic lane occupied - with exceptions to that (very wide lanes) being pretty rare.
A shortcut has to be a challenge, otherwise it would just be the way. No situation is so dire that panic cannot make it worse.
There are two kinds of people in this world: those can extrapolate from incomplete data.

I can’t help thinking that wording of the original post is somehow wrong. I’ve voted for 1.0 metre as that’s enough of a gap for me and my bike to get through and the next lower value (0.5 metres) is almost certainly not. However I recon a motorist should aim to allow more than that width, aiming to leave a metre or more between cyclist and vehicle seems a reasonable start point to me - give me 2.0 metres out from the kerb please.

Brings to mind the story I read in one of the Guy Martin books. He was practicing for a mountain bike race and decided he'd use the lorry inspection pit to practice jumps so he set up a ramp to get some air before landing inside the pit.

His words were " he thought to himself, while laying at the bottom of the pit with a broken thumb and dislocated rotator cuff, -- at no time during the setting up of the ramp or even flying though the air did I wonder if the handle bars were wider than the pit !!! "

+ 1 hence the Guy Martin story.

I reckon that’s 14 days and all will be revealed :D
I’m sure that’s what @ freeflow promised but I can no longer find that OP post has it been deleted or was I dreaming?
Whatever I’m still eagerly awaiting the explanation :wink:

Edit: found it!

For a bit of educational fun. This poll has been prompted by a couple of discussions on this forum and watching some cycling crusader videos. You can choose two options to indicate a range. The poll will run for 14 days. Have fun
Whatever I am, wherever I am, this is me. This is my life

Gosh, that went quick. I'd assumed I'd get a notification as to when the poll closed. As I'm just off on a 90 km ride I'm afraid you'll have to wait until tomorrow.
