No, you can attach it to the scooter itself.

I used to carry a small lock, mine had wheels with open spokes. People used to bully me being like "haha who would steal a $80 childrens toy" but honestly the first thing someone does when seeing a scooter is ride it so like it would be stolen in seconds I reckon. Way faster than a bike.

>build more bike lanes
a lane is a portion of carriageway dedicated to the transit of vehicles or a subset of them. A cycle path is a segregated "carriageway" dedicated only to pedal cycles and sometimes other vehicles.
Indeed, building a cyclepath implies building pedal cycles only lanes on them but building pedal cycles only lanes DOES NOT imply building a cycle path as the pedal cycle only lane could be added to existing carriageway.
Educate yourself stupid mutt. Learn what words mean and what is the first-order logic.

No. In order to construct anything, the government needs to buy out part of the construction sector for these projects. This means less real estate being built, and real estate is most of America's GDP. Most citizens have no job or house, so there's no reason to build infrastructure for them. Just build houses and sell them to middle eastern kings. US isn't even a real country.

Post whatever aesthetic photos of trains you took, ima start

In this photo I captured the 843.011 DMU in its original livery and with a matching class 043 passenger carriage, on the morning R 1376 "Ještěd" fast train from Pardubice to Liberec.
Taken on the 7th of November 2020 between Pilínkov and Liberec.
This service used to be named after the bigass mountain and its tower in the distance, Ještěd. Sadly, as of today, this fast train service is owned by the Arriva company.

Sure is, dont forget about Slovakia though, they are on a very similiar level :P
Both of our countries still have very many first generation electric locos in service, old diesels, lots of heritage trains, steam locos and such
Anyhow, when it comes to regular trains, I give our railways about 10 years before things get really boring and dull
We do have a a big advantage though, Poland, Hungary, Ukraine etc. is not that far away, so once our railways are done, we will just go a bit further east.. thats what the Germans are doing these days, their railways got pretty boring and now they come to our country all the time :P

Anyhow, to keep this thread from dying.. in this photo, I captured the 242.247 first generation electric locomotive leaving the Mírovka stop with a passenger train from Jihlava to Havlíčkův Brod, 21. 8. 2020

Recently I got really interested in velomobiles.
I am thinking of building one myself, due to high prices and in my opinion some questionable design choices of consumer ones.
My primary use would be commuting to work and stuff. This way I also get to do some exercise and commute at the same time.
Also I would use it to travel/tour. Maybe with full reclining seat, I wouldn't need a tent.

Has anyone here driven velomobiles, maybe even tour in one?
What did you like/hate? What would be your concerns?
Any experience and advice appreciated.

And why are consumer ones so weird looking? Some of the racing HPVs look much better. https://www.youtube.com/watch?v=C9ZLfd5c4Iw

Do the aerodynamics on these actually work? Seems like it would be a lot of extra weight with little actual benefits. Most drag is surface drag at this speed anyways
>>
>>1630369
I don't exactly know how usual research is conducted, but I imagine 2 different paths: One is; where company pays to get their "innovative" product tested against conventional product - this can lead to some bias towards that new product. Let's say that boundary conditions can be set up in a way that favours one product.
The other is where there is more non-biased testing, with genuine interest which product is better, with no connection to any brand. Usually internal testings in companies, or maybe before investment or something or consumer report.
>>1631005
I didn't mean cut corners in necessary bad way. More like design decisions they make. They design stuff for more or less mass production and cutting the costs down . I do not have those restriction, but different restrictions. so their product (which might be the best possible solution for their restrictions) might not be fit for my case. Let say derailleur: developed 100 years ago and chosen to be the best. for that time. For manufacturing in that time. Then it was built upon that and improved through the time. Today's versions might be the best possible version that can exist. But it is all based on some decisions that were made 100 years ago. And I do not know what those decisions were, therefore I cannot choose if this is fit for my purpose or not. And in commercials they don't tell you why they choose to do things this way, so people cannot make informed decisions. That is why I do not trust commercials, because their purpose is to sell you stuff, as it fits that company, not as it fits me or you.
I am also thinking more and more that it might be a good idea to use some different system of power transfer than usual cranks and chain.
>>1633222
It seems so. according to some basic aerodynamics it should work. Look here >>1631549.

Where are you going to store it? It's going to occupy 3x the space of a regular bicycle.

The bike + rider height is going to be much shorter than a regular bicycle + rider. You're going to get run over.

Super aerodynamic velomobiles make sense at high speeds. If there are lots of hills on your ride, it doesn't make sense. On the flats you will probably be operating too fast for bicycle lanes so will have to ride with traffic, but you still won't be as fast as traffic, and you'll be super low to the ground and no one will see you.

Bad vibes.
>>
I find the idea really cool, but in practice there are too many problems for it to be a viable for most people. Yes, you can go faster on flat ground for the same effort, but on hills you'll slow down to a crawl, in corners these things are complete death traps and they take up a lot more space than a bike.

>>1637706
As always, it requires effort to fix its problems and is different from what you are used to.

The age of the round chainring is over.

Through an exhaustive R&D process to refine the oval chainring we discovered that optimum pedaling efficiency didn't come from subtly altering the circle, it came from a whole new shape we call the 'square'. By breaking the pedaling action into 90-degree segments the rider effortlessly puts four times more power to the rear wheel. In between these peak power moments, there is the restive stage of pedaling which riders report a 90% decrease in fatigue.

The unique geometric shape of the 'square' also provides our Quadrant rings with the revolutionary Parallel Chain Retention Technology. While conventional chainrings can only have 180 degrees of chain contact, the Quadrant ring has up to 270 degrees of contact that eliminates all chain drop. Forever.

Easier pedaling, more power, less stopping and dropping.

The Future is Square.

What are your thoughts on older bikes?
Are there specific eras where particular types of bikes, road racers for example, peaked?
Does new always mean better?
We know that technologies always reach a point where they effectively become 'solved', in that our understanding of them is complete and there is no real way to improve upon them. But technologies related to cycling in general seem to be continuously evolving and improving, or is that just an illusion?

Built in obsolescence has been around for a long time now and exists in all things manufactured, both physical and digital, think about the rock solid durability of the early i-phones compared to the fragile and coded to die modern equivalents, and even though they are now mass produced almost exclusively by slave labour in China using the cheapest possible materials, the prices keep on rising. Has bike manufacturing reached that stage yet? Of course if an i-phone fails it's unlikely that the owner will suffer potentially catastrophic injury, whereas if a bike were to fail then it could easily result in death, so perhaps most reputable bike manufacturers realise there's a limit to how cheap and 'built to fail' they can push it.

With everything we buy in some way being designed to fail at some point, thereby encouraging further consoomption, is this true of bike frames and components?

Also manufacturing techniques have changed a lot over the past century or so, is a hand built frame really going to be better in real terms than something assembled by am efficient machine? What about design and even over-design, we all know examples of bike that seem just about peak for a particular purpose, just as we often see memes bike on here that have clearly been overthought.

It would be interesting to hear from anyone with a vintage bike or those who simply have to have the latest cutting edge stuff.

What is the apex bike or frame, brake, gearset or wheel?
