I've blown up beverage bottles for fun. Hooking an air compressor to a 2L bottle and exploding it makes a satisfyingly loud boom. *We had a valve on the air line so we could be at a safe distance when pressurizing. Be very careful. It's unpredictable exactly at which point they'll blow. Sometimes they hold full pressure for a couple seconds and then go.*

i like to use dry ice for pressure, make sure you have a gun to shoot it if it doesn't go off

When we did it, it always went off on its own. It's been a long time since I did it, but I think the longest it took would've been on the order of 30 seconds. Really makes a person jump when it finally goes.

And yet you immediately started with an anti-cyclist whine while ignoring pretty much everyone else. These debates are so stupidly tiresome.

You have brain worms, I started by explaining that I am a cyclist. Obviously not all cyclists are particular ones I disagree with.

Parasites are more common than anyone’s comfortable with.

Not to be pendantic (but to be pendantic) 80psi is the correct pressure for 28mm tires ridden briskly on good roads. At least according to ye olde Silca tire pressure calculator. Back in the day when folks ran 23mm tires they would typically run above 100psi (though that may not have been optimal...).

That calculator is wrong. Cycling people have been overinflating their tires for ages (as well as using too-narrow tires), with the assumption that the ground is perfectly smooth. Lower pressures yield higher efficiency (and better comfort) on rougher surfaces.

Surface quality is an input in that calculator.

This seems to be part of a type of brand marketing where a brand claims it has invented something, but the only thing that ever exists of significant economic value is the attention raised by the promo video / article. Not the thing/service. Examples: - Samsung safety truck https://www.youtube.com/watch?v=6GNGfse9ZK8 - Citroën motion sickness glasses https://www.youtube.com/watch?v=Aco63dlq_WE - Amazon Prime Air http…

Their dealers already sell a bike bell, eg. in NZ at https://store.skoda.co.nz/products/bicycle-bell and in IE at https://www.skoda-accessories.ie/ie/en/p/bicycle-bell/SK-000... There is a Czech shop listing for the old bell at https://eshop.skoda-auto.cz/en_CZ/bicycle-bell/p/000050305C Presumably the new bell will eventually appear among the other items at https://eshop.skoda-auto.cz/en_CZ/cycling-accessories/c/cycl…

Thanks for the NZ link - just bought that bell as that's a pretty reasonable price & includes free shipping :)

What if you would rather stay in the bicycle lane instead of terrorizing pedestrians? Quite a lot of taxes were paid for those lanes. Use them, and stay out of my headset.

E.g. in Germany many pedestrians, especially tourists, tend to think that bycicle lanes are fancily-painted sidewalks

Interesting. In Switzerland I see exactly the opposite. The country is full of empty bike lanes, and pedestrian zones which are overran by cyclists and e-scooters (of course they are adjacent to the mentioned empty lanes).

Over engineering in real life, solving lack of common sense by introducing a solution where the cyclist is paying. I think the solution is nice for sure, but solving the wrong problem.

> lack of common sense

Walking in noisy environments is most of the usage people get out of noise cancelling headphones. The other use case is noisy workspaces or coffee places.

Do horns and bells really prevent accidents? In order for e.g. a horn to work you need enough time that the driver processes the situation and decides the horn will communicate something AND enough time for the pedestrian or whatever to process that and react to it. Generally it's a lot easier just to press the brake, and more importantly be travelling at a speed and in a manner where the brake is sufficient. Structu…

A horn or bell is mostly for telling other people "hey I'm here, stay out of my way and dont suddenly cross into my path" My opinion as a cyclist is that I should basically only be using my bell on pedestrians when the pedestrians are wandering onto the bike lane. If im cycling through a shared space, I find it extremely rude to ring the bell, because it feels like I'm telling people to get out of my way, but they ha…

We are required to have a bell in Ontario. Ontario, at the minimum, asks us to ring a bell, or verbally communicate, when we are passing people.

I've lost count of the amount of people walking abreast taking both sides of a shared path.

I've lost count of the amount of times I've rang a bell in vain to inform them of intent to pass.

I've lost count of the amount of times I've tried verbally communicate in vain, to inform of intent to pass.

And then these path users, completely oblivious of what's going on, act like I'm the villain when I do pass them despite doing what is required of me. Some even had holler back saying that I should have ran a bell, or tell them.

If one's using a shared path, don't use headphones that completely block outside sound. If one wants to meditate, then get off the shared path.

> Some cyclists ring their bells because they're worried a pedestrian might suddenly turn into their path, This is wrong - on mixed use paths, it is customary and proper to announce "on your left" when passing, and a bell is a nice alternative. Even cycling slowly pedestrians can do some very erratic things, and moreover are very surprised when cyclists suddenly appear on their left (and may do something dumb in surp…

Announcing "on your left" is a great way for someone to move left, because more often than not, they're oblivious on the shared paths, and the spotlight effect messes with their head.
