Anecdotal evidence - i never wore helmet when growing up, nobody did. once had an accident on small bmx bike when I fell head first on tarmac, but didn't land on head and apart from scratches and being shaken all good (if parents only knew...).

few years ago decided to buy new cross country (ie all-rounder) one, lightweight and blazing fast for what it is. Decided to go for a helmet for the first time. After 2 weeks, had a head-first fall because of my GF stopped on some narrow forest path uphill, behind the corner and I hit brakes full power when I saw her with no place to avoid.

I miss few seconds of memories, just waking up laying in the grass, picking my head from sharp pointy stone sticking out of the ground - helmet hit it in forehead area. Have I not worn it, it's more probable than not I would die there, I was still badly shaken from impact force on my head, and I was driving slowly when it happened (10-15 kmh).

Fiancee works on emergency, the stuff she sees daily makes her wear helmet too. Link all articles you want, we're keeping our helmets where they are, on our heads, thank you.




This focus on helmets is ridiculous, because you only have to types of bikes:

1. Death traps

2. Dutch bikes

You want less people to die in traffic while riding a bike? Don't make a helmet mandatory. Make the dutch bike mandatory. Your bike needs to be heavy. You need to sit up straight. And if you stretch your legs you have to stand.

Whenever i see the images of americans on rice bikes and mountain bikes in NYC, i too think it looks incredibly dangerous.

If i would hit a door with a dutch bike, i wouldn't fall, i would just stand still. And the door will likely be a bit broken.

It's not about the helmets. Its about the bike design.


“If i would hit a door with a dutch bike, i wouldn't fall, i would just stand still. And the door will likely be a bit broken.” I'm sorry but this is nonsense. Even if it weighed five hundred pounds, as long as the handlebars are on a lubricated pivot, forward motion and striking the handlebar will knock the bike over.

p.s. as a NYC cyclist, whenever I see a Dutch bike I think it looks incredibly inefficient. But that’s cool, whatever, all bikes are good as long as they're ridden safely.


Dutch bike are different, more sturdy, built for bad weather, built for being outside in rain and wind and cold all day and night. Most of the time they are parked outdoors because there is no room to park them inside the house, especially in the bigger cities. They are relatively heavy, but simple and can easily survive twenty years outside. They will look horrible, dirty, old, broken, and they are.

Many bikes here have wheels that are not straight anymore. But still they are used daily. Tires are soft, chain is worn out, and still it works. They not only carry the cyclist but also his or her friend on the bagage holder on the back, which is probably wobbly.

OK, what I'm describing here is the typical student bicycle. It may not be efficient, but it is cheap and it works and it gets you there. We don't use these bicycles for long distances, but for short onces, going from home to the supermarket or school.

In Amsterdam and Utrecht at Central Station they have bicycle parking lots for about 20.000 bikes. And many times you have to search and search to find an empty spot. When you park your bike here, anyone can throw his or her bike against it, or pull another bike out of it with force, damaging your bike. Not everyone acts like this, but it happens now and then.

So bikes are efficient in a different way than the bikes I see on pictures in NYC.


>Even if it weighed five hundred pounds, as long as the handlebars are on a lubricated pivot, forward motion and striking the handlebar will knock the bike over.

The weight point is different. You really don't flip 'over'. That direction is as likely as flipping 'under'. Given enough momentum and a very heavy/strong object you ride into, your front wheel will collapse.

Again, on a dutch bike, all this has to happen at at most 15 km/h. You put your feet down and you are standing still.

>p.s. as a NYC cyclist, whenever I see a Dutch bike I think it looks incredibly inefficient. But that’s cool, whatever, all bikes are good as long as they're ridden safely.

They don't just look inefficient. They are. By design. They are faster than walking, and that's enough. Our trips on average are about 10 to 30 minutes at at most 15 km/h (<10 mph). They involve about 10-200 turns, about 3-50 stops.

Why? Because that's how they build the cities. If you ride at that speed, you wait for a green light just once (and then follow the wave though-out town). You can go faster, but then you have to wait at the next intersection. Also: you don't want to get to work/school/friends needing a shower. The amount of energy put into it, needs to be identical to walking for the same amount of time.

People move children, groceries, even furniture by bike. So they pick a bike based on durability, size, stability and how well you can stand still while remaining seated on your bike.

They turn a distance you can safely walk in an hour, into a safe 20 minute ride. And like most cities in the world, the cities are designed around the 30min travel time from any point A in the city to any point B in the city. This is by bike or public transport. By car it generally takes twice that time.

Why? Because cars are more likely to get stuck in traffic. They often have to take detours (many streets are just one direction). They have a problem finding parking space, etc. And then you pay about 1 to 5 euro per hour to park your car.

But if police sees a race bike going 30 km/h (20mph) they would stop it.


A little less "team Holland Bike Police" attitude please - I find those sit up and beg bikes unstable when riding at slow speed I felt much safer on a proper SWB MTB with proper rakes


Aren't you more in a begging position on a road bike?

:-)


The drivetrain matters too--I suspect many American bicyclists blow through red lights and generally don't respect road rules because with fixed/single speed bikes, it takes enormous effort to get started from a standstill, and with derailleurs it's impossible to downshift from a standstill (i.e. when you make a quick stop). If hub gears were standard, bicyclists wouldn't have as much reason to ignore signals.


No its not you can down shift with index shifters on the MTB very easily as you stop and you can always lift the back when and quickly shift that way

Agree that fixies should be banned outside of a race track.


How about until such a time that society can provide a safe means of cycling, we let cyclists decide how they are most capable of staying alive. Riding a slow bicycle and stopping at every intersection is incredibly unsafe in many American cities.

Yeah, a fixed gear can be an encumberence to a poser, but to someone qualified, it can also be a means of greater control.


> Riding a slow bicycle and stopping at every intersection is incredibly unsafe in many American cities.

I don't think blowing through red lights at or near full speed is any safer. Come on, at least do a California roll.


Certainty in London at any busy junction you can see fixies blasting trough red lights at +25/30 MPH with no regard for pedestrins


Don't you still have to pedal forward in order for the chainset to actuate the gear change?


You just push off with your foot from the ground, giving you enough forward motion to down shift.

It's easier if you downshift before stopping, but the only time it's a problem is if climbing a hill, in which case you probably downshifted anyway


Ah, I see what you're saying--the good old forward kick from standstill.


What about electronic shifting?


You're supposed to downshift before you stop. With indexed shifters on the brake lever, it's trivial to do as you're braking for the stop.


So, in summary, a helmet is a good idea if you drive full-speed around corners where you have no idea if it's clear?


based solely on my experience, apart from the part about full speed (i really wasn't going fast, maybe 20 kmh but terrain was bad), yes.

If I include what fiancee sees on emergencies, which most people don't even want to know about but it's real life anyway, then wear it everywhere on bike.

you can see people getting quite emotional feeling they know what's best for them. Usually never had an accident, so it cannot happen to them. Whatever, I wouldn't push it, use whatever you want. But 1) you will cover all medical cost caused by lack of helmet in case of accident and 2) I would be cautious what to push on kids, but once people get emotional on the topic any discussion is over, as seen in this thread
