i don't know anything about bicycles despite having one since i was little, i got another one for 50 "pounds sterling" last year and it seems fine. i don't get all the bike stuff. should i actually care? the wheels go around and the gears shift and i go somewhere

drwhat, make sure to get one with shock absorbers for comfort and to wear a helmet
#328
You'll want more absorber than actual bicycle. Big soft shoes help too, Uggs if you can afford

Uggs



yase,

also if its still uncomfortable get a wide saddle with springs underneath, that helps

#330
dont get any fenders or mudguards though, they fucking suck

can you even rent a manual in the usa?, i forgot that automatics are even a thing, trust amerikkka to suck all the fun out of everything

anybody who wants to step their bike love up will dig "Lugged Bicycle Frame Construction" by Marc-Andre R. Chimonas

steel-frame bikes with lugs are stronger, last forever, ride smoother, can be built at home with cheap hand tools, can be brazed instead of welded (ie no skill involved except watching a youtube), and can be fit exactly to your body. in all my years of bikeriding, i have never had less than 1 kg i could lose, which is ~ the weight difference between steel and Al/Ti/carbon.



for some reason lugged framebuilding has become one of those luxury craftspeople things. its weird because the lugged method is explicitly about getting away with sloppy work in a mass production setting. since the lug does all the work you can do the shittiest least well fitting pipe cutting you ever seen and it doesnt matter.

i don't think so, no one knows how to shift one so it would be a big liability. not all automatics have such timid shifting points though, also highways in the most populated part of the country have lower speed limits



that legit sucks, taking away gear and clutch control from driving would neuter the whole experience.

edit: on second thoughts drunk posting about my past as a dangerous and irresponsible driver is not a good idea

Well the mass production settings that exist today favor either aluminum at the low end or carbon at the high end. Yeah another import market that has chosen the absolute least durable / repairable materials for the given setting

#339
oh you gotta love the department store low end that's still steel. you know those $99 mountain bikes where the frame is like this. i cut one in half once and im 100% convinced they're made of offcuts from like, steel framed buildings, or bridges or something. it was about fourteen times as thick as a normal bike tube wall. i guess they like that because it means they dont have to worry about the 7 year old accidentally burning a hole with the welder

What type of steel do you even use, how thick is the wall of the tubing
#342
how int e fuck is it judgmental to note that the best way to mass-manufacture bicycles has been relegated to the shops of couture bike crafters while planned obsolescence rules the day?

nothing i said goes against the idea that it's a project that someone can easily do. infact that's exactly what i said, that using lugs makes it easier, because thats what they were invented for, making it really easy and fast to make bikes.

the people who make it seem super complicated and elite are workshops like mercian and pashley who market this totally ordinary thing as if its equivalent of like a rolls royce when its not.

but since you decided that i did that, i will now. to build a lugged frame you're going to need a emery cloth, degreaser, blowtorch, flux, brass or silver rods, dremel with cutting and grinding wheels, wire wheels, facers, thread tappers, and at least a couple of jigs to hold everything together. you'll also need a workbench and good ventilation. but before any of this you'll need to know what kind of parts you'll use to make it a complete bike because that determines stuff like the location of cable stops and bosses or threaded screwholes

so fuck u

for something like Reynolds 531 tubes (what most good bikes used from the 1930s to the early 90) about 0.8mm to 1mm at the ends and about 0.5mm in the middle. they made the ends thicker like that because thats the part that gets hot when they're attached together, and heat weakens steel. R531 is a manganese–molybdenum steel alloy that's extruded into shape

a cheap bike would be made of generic, weaker steels that'd be 1mm thick or sometimes more all the way through. those tubes were made in a different manufacturing process, where it'd come in flat like an unending joint wrap and go through a series of rollers to make it round, then the seam was welded. they'd just chop off the right lengths as it came out of the machine

for ref the cheap mountain bike i cut in half with a grinder to throw away easier had walls about 8mm thick. that answered the question of how something sized for a 6 year old weighed 17kg

sorry



its cool. if youre looking to experiment with brazing bikes together there's a sheldon brown page about frankenstien tandems where he shows how to do it. the bikes he recommends are getting a bit expensive now tho

#349
Rigid metal conduit has a wall thickness of 3mm apparently. I've always wondered how that shit compared to bike tubing
#350
yeah dont need hardly any thickness in a bike frame at all, its mostly tension load because triangles. downside is they can dent and even buckle if you do some dumb shit

its all pretty repairable if its bent or dented. people nowadays are used to aluminium which fatigues easily, so forums get clogged up with "you bent your fork? its a deathtrap throw it away" type posts. i seen a wizardbeard looking old man in the shop fix that with nothing but a vise and thick plank of wood

here's a guy rolling out dents



aluminium is a dumb material to make bike frames out of imo. it can't tolerate flexing about like steel can so they stiffen it up with bigger diameter tubes and suddenly you can run over a braille textbook and read it with your ass

I feel inspired to also bike down new roads. fuck streetcar/rail tracks! how the heck are you supposed to bike around them?
#359
ride over them at like 45 degree angles

today i spent a couple hours repeatedly repairing the same puncture. the patches would go on okay, but as soon as i started inflating, they'd bulge out super thin like a snot bubble then pop. i think it was a bad batch

then after i finally gave up and used a different repair kit, i found that i'd broken a spoke when the pothole burst the inner tube

fuck my life
#360
So has this thread come to the conclusion that the only material that should be used in bicycle frames is titanium
