T/o/urist here, can one of you guys explain to me who buys these things and why
>>2018255>50cc is not very fastLol lmao1st, you can't go on the highway with them2nd, minimum highway speed, like I've said, is a paltry 60 km/h (up from 40 till a while back)3rd, picrel: https://m.youtube.com/watch?v=hZ1FOxkrvBc
>>2018262This is practically a Reliant Robin in reverse. Do they tip over a ton, too?
>>2018262That has 4 wheels; how is it considered a tricycle? Picrel used to be cheap and sold to retirees, now they can be as expensive as a small car, and are sold to the underaged: https://www.aixam.com/
>>2018283theyve always been expensive because its a niche
>>2011319The tour de france race camera uses one as it is more stable in the mountains at slow speeds.
SS United States to be sunk, creating the world's largest artificial reef. RIP to one of the greats.
>>2018458It's 60 times more efficient per ton, than even a train.....slow is efficient just not per time, and faster times are just low character enabling horseshit. Slower travel makes people more deliberate/intentional. I've never been on a commerical flight. Don't tell me you prefer that cattle car to playing shuffleboard and fresh air even if it takes a day to get to the same place.
>>2015994>SS United States to be sunk, creating the world's largest artificial reef. RIP to one of the greatsYou guys are so negative this is going to be awesome. Fort Walton Beach is the middle of the redneck riviera. It'll be beautiful. You'll be able to dive down at a fairly reasonable depth and see fish and sealife around this classic beauty. People will pay to dive and help the economy. And companies will bring those little tourist mini-subs down to view the fish and boat for the old people- a very /n/ thing.Plus it's the USS United States. It's not seeing it's end being stripped for parts in South India like most scrapped ships. It's going to be a tourist attraction and provide natural barrier.
>>2018523It'll probably be a technically advanced dive to see it. I don't know if they'll require 80 feet like the Oriskany, but it also needs to be deep enough so storm and wave action don't disturb it.It's not the USS United States, btw, just SS.
>>2018470That was clearly a joke dumbass.
>>2015994I'm going to miss seeing that thing out of the food court at the south philly IKEA.
Disasters never have one root cause and neither did the destruction of cycling. But I know some important milestones in the decline and fall:1. COVID 19. Enough said.2. Full suspension mountain bikes. Enough said.3. Reddit. Enough said.4. Twitter. Enough said.5. British "people". Enough said.6. The d-tch. Enough said.7. The state of Utah. Enough said.8. Zwift, Peloton, "Spin Class", and other cancer. Enough said.What were some other key moments?
>>2018633>Each new product that nobody needs is defended by ignorant children repeating the marketing BS they heard on their favorite YouTube channelPeople parroting marketing spiels as a stand-in for actual experience is what's destroying a lot of hobbies. Maybe things have always been like this and I was ignorant to the fact when I was younger, but it seems to be worse now.
>>2018639It's always been this way, it's worse now because the loudest "experts" have the means to shout via social media, idiots now have accessibility to a very wide audience. Before social media, there was TV, radio, records, magazines, newspapers, books, etc, it's just the barrier for entry to a global audience is as easy as having a phone and being loud. Everyone is a self claimed "expert" now to the point where only real experts can filter the noise.
>>2018639>>2018642Yes, prior to twitter cyclists had to rely on reliable neutral sources sold in newsstands printed and distributed at a loss by devoted enthusiasts who didn't care for sponsorship or advertisement money at all, zoomers finally figured it out!
>>2018646The difference being that now all of the dogshit available in that magazine isn’t behind a paywall anymore but shoved down people’s throat on social media
>>2018647You're delusional if you think the difference is anything other than latency

>>2017534Around here we post bike when we talk about setups. Are you new here?If you weren't such a cocksucker about Di12 shifting of all things I'd ask you how you like it, etc. You could have a little forumn to show off your setup. But you were mean so you get no hotdog.
>>2017469No you don't need to remind me >>2017464 . You told me. Like I have said: I have never tried it. I don't know any technical details. All I know is in my statement above: Cables work well enough, I can hardly imagine any worthwhile improvement. Cables have proven to be dependable and while, assuming you're correct, it would be a merely academic discussion, cables still last longer. Then again this begs the question: Wouldn't the battery life depend on how much the system is used? Does this mean they have assumed the mileage of the average cager and lifestyle / fitness cyclist, who rides maybe two hours every day and a bit more on weekends?
>>2017523I definately DONT want to wait 15 minutes for my bicycle to be charged first thing in the morning and sometimes wouldn't even have a chance to do that.
>>2017464This is why I still use a pedal bike most of the time even though I have an electric bike that can go 30mph. It's just so much more reliable. >>2017465>trickle downThat's the problem. Eventually you will only be able to buy a bike with electronic shifters like how all car manufacturers switched to touchscreens just because it's the hip new thing even though buttons were easier.
>>2017546I see about one electronic shifting failure per month on group rides. I don't believe they're as reliable and retard-proof as some people make them out to be based on what I've seen.

how would a society where personal passenger cars dont exist and only public transportation (no taxis) are available look like? In this scenario public transportation would extremely good and developed and alll of the cities roads and infrastructure would be focused on faciitating public transportation. Parking lots would be unnecesary and roads could be much smaller. ingenious new ways to move people would be common, like cable cars. Could such a city be better than one with personal cars?
>>2017666There will be private train carriages and first-class carriages like there was a hundred years ago, politicians and the rich will always find ways to separate themselves from the rabble. Also, they will likely redefine what "public transport" is so they can still have their own cars and jets.
>>2018575I can easily see vehicles being held in elusive trust, sort of like the way the super wealthy get around modern machine gun prohibitions.When you are rich and well connected you can pay someone to spend 40 hours a week looking for loopholes for you instead of wasting your valuable time yourself.
retards really don't understand the massive land usage and cost of roads
>>2018593>massive land usageWhy is it only roads that have a "massive land usage" problem? Where's the outrage over farms, solar power plants, mines, landfills, railyards, etc.?
>>2017666Absolutely terrible. It’s a shift of responsibility from the individual to the State, who literally only considers you to be a corporate drone - a cog in the system that supports their lavish lifestyles. Take away the masses and their electricity goes out, their clean water stops running and they no longer have drones (errr sorry I meant mechanics) to maintain their private jets and helicopters. >cars represent an unprecedented level of freedom and power for the masses. You can dream about a car free utopia but that’s all it is. A dream.It’s also funny how so many urbanists are socialist/left wing/defund the police supporters who favour mass surveillance and policing Twitter while actual dangerous criminals are mugging old ladies on the street, unpunished. You can’t even get the basic framework of society right, much less create a car free world where people are actually happy with the arrangement.
am i retarded how is this possiblethis doesnt seem sustainable in the long term
>>2015667That's basically what all the south african fuel comes from, and the process is very much the same as the production of the planned sustainable aviation fuels except for the source of synthesis gas (which is the easiest part of the process)
>>1975311>all motorised travel is roughly equally irresponsiblewhoa no shit sherlock!
>>1974908It is because planes are much faster than boats. If you're running low on oil, just make more.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8468670/
>>2014470Haha, and where does it come from?
what fraction of the movement is people moving around to do things that could be done remotelyhalf?ZOG pays for their golems to fly around to "oppressed" areas and then fly back monthly
Has anyone thought about using one of these scaled-up for large diesel engines?Having these allows for keeping air/fuel ratio optimal (λ = 1) through a larger range of power outputs and increases efficiency by allowing for the extraction of more energy from the exhaust gases. For instance, a diesel locomotive could use one to boost power to its motors or for head-end power. LNG carriers could use the energy generated to refrigerate the cargo.I understand it'll be complex and difficult to implement but the potential is huge.
>>2015259>having the turbine driving a generator/alternator and acting as a pseudo-APUEmma-Maearsk class container vessels use the APU solution - a second turbine behind the turbocharger drives a generator. Additionally, there's a two-stage steam generator with superheating behind that to use the exhaust heat in a steam turbine also running a generator.The electricity can power onboard systems, refridgerated containers or (through two 9MW motors on the propeller shaft) be coupled back into the driveshaft.It's a very interesting system from an engineering point of view.There's 30MW of diesel generators on those things that don't normally drive the ship, plus a 82MW main engine. The electric motors allow a total of 100MW on the shaft, or for the main engine to run the electric load too. Pretty unusual for large ships but allows load-point shifting at low speeds (huge efficiency boost at high development cost)Exhaust is gathered from all engines for the heat recovery system and can bypass the turbos as appliccable.The steam turbines can make 8.5MW, the exhaust turbine another 1.38Brake thermal efficiency reaches 55% like thatAll numbers according to wikipedia.

How do the Japaneee get away with branding their folding bikes with car brands?Anyone here tried these folding bikes?
>>2015925Mercedes and BMW designed theirs in house afaik.
>>2016329Hell, Peugeot built bicycles before they started building cars, they're as traditional and established as it gets.
>>2015104You can by a Ford electric bike on their website. Going by IP rape eternally by the chinese is nothing to go by.
>>2016329It's actually PFIIGFOT
>>2015104>How do the Japaneee get away with branding their folding bikes with car brands?>Anyone here tried these folding bikes?I bought a 2001 Jeep Liberty when it came out and they gave me a full susp Y frame bike with it. It was awesome but so heavy (I didn't know better). Even being heavy it was a city park princess- essentially a great replacement for a cruiser but not sturdy enough to ride an MTB park. Triple in the front. Y shaped frame, coil spring back susp.I chained it to an iron fence and left for the weekend and when I came back it was stolen.Used it for 5 years and got probably 2500 good miles out of it riding around town.
Anyone work for Lime/Bird/Whoever? Any numbers that these share programs are a success? They had them in my distance suburb satellite, and lasted maybe a year. I used a bike share one way on Chicago after taking the train from Milwaukee. Anyone else love the grossness of handles and seats you can't imagine the filth of? How many units have you seen on their sides/not at docks/in canals. Are the another scam/handout band aid on the cancer of car dependency?
I excepted share bikes to be a specialized scam of course, but this is the 40,000 dollar pentagon hammer all over again.
heres a very work in progress pic of my 3x13 39speedi couldnt see any reason why a 13s wouldnt fit my 9s hub and it seems to so far lol, wit a spacer toodesu im probably gonna convert it to a 2x11 at some point to save weight this is just for funsiesim also running a 12s chain because 13s are silly expensivewhat are the chances this fails epically?
>>2017605I don't think it's worth doing on a bike that isn't cool and kinda fancy, like OP.
>>2017608You are probably right and it would probably end up costing more than I'd be willing to spend... and then the mixing and matching of parts... and just finding and assembling, and then maybe fabricating to make it fit to a frame it was never intended for would take too much time.
>>2017610>fabricating to make it fit to a frame it was never intended for>would take too much time.those are both nonsense reasons, wtf would you have to 'fabricate'? Bicycles ARE intended for such things. >i want a silly meme project but i'm lazy why even bring it up lol
>>2017611bro I was just inspired for a minute or 2 lolseriously it would be fun if I had a ton of spare parts at my disposal, but I don't
What is the intent behind statements like "I'm not a cyclist, I'm just a person who gets around by bike"?At a surface level it is obviously meant to (proverbially) throw other cyclists under the bus, but to what end? Would it somehow appease the anti-bike people if the person "blocking traffic" didn't agree to be referred to by the word "cyclist"?
>>2001345Here is some context from a Dutchfag, a large amount of Dutch people live in relatively small towns and commute into the Randstad (Most urbanised area of the country) for work. It is not realistic to bike from outside of the Randstad into it. However, if you actually live in the Randstad, and work in the city you live in most people then choose to bike. Getting around the place you live though? It's cycling all the way. I almost never leave the house without my bicycle whether it's going to friends, to the store, or just to the nearest city. TLDR; Commuting by bike largely isn't possible for most of the population not living and working in the city they live in. Also, public transport is more expensive compared to automobiles.

I am looking for a youtube channel of a guy or group of guys putting heavy mileage on ebikes.Maybe food deleivery ?What I am looking to learn is about how well these hold up under heavy use and what mainanace issues there might be long term.I live out in the boonies and need to commute 22 miles each way every day so the miles are really going to add up
>>2017947EbikeSchool and Electrek, both channels with Micah Toll, are good spots to begin. In general, hub motors will need to be checked for gear tooth wear and kept lubed, mid-drive motors will require more chain/cassette maintenance and swapping due to wear. Some kind of tire liners/flat protection is helpful, too, I use Mr. Tuffy liners for my cargo bike, if you live in a place with lots of broken glass/goathead stickers, Tannus armour inserts might be necessary.https://www.youtube.com/watch?v=ckeFFTffQZc

From old to new, big to small, I have almost never heard of;>Planned Obsolescence>Vendor Lockout>Poorly Speced Components> Quality Control Problems>Price Gouging>Lack of Parts Availability(Even on equipment from the 70s)>Dealerships being so much as impolite to customers (even if they are only buying one part for a 50 year old machine)Comparing similarly sized machines with skid steers, its night and day. In the general world of heavy equipment, everything is whittled down into something that just barely lasts through the warranty period, except for some reason forklifts. Why can I buy a forklift that is so damn well thought out, reasonably priced and dependable, but not a skid steer, dozer, washing machine, car or truck?
>>2015529Forklifts don't and can't have any safe failure modes.
>>2015529Forklifts come with service plans that are factored into the cost of buying a fleet of them, right alongside liability contracts for avoiding downtime. And and in order to keep that cost down, they need to be dead simple and reliable. Not just because the repair and maintenance needs to be cheap, but because if downed equipment impacts a customers profits, the company selling the lifts will be sued into the ground shortly after, and subsequently have their reputation tanked.I work for DHL, we buy Crown forklifts. They’re simple machines, propane 4 cylinders at their core which require little maintenance and can be abused horrendously without batting an eye.If they had say, some flawed component that caused 3/4 of the fleet to fail one day, that would cut our ability to move freight so heavily that it may shut down a customer.And in that scenario time becomes money very fast, like $10,000 a minute fast on the low end. If that shutdown is deemed to have been the fault of the equipment provider? They will pass that bill down until it’s Crowns problem.So crown brings us solid equipment, because they can’t afford to do any nonsense since the outcome for product failure isn’t like how the automotive industry handles it. If the Corolla sucks for some reason one year, big deal, there’s some recalls and people don’t like the Corolla name for a while.If a certain range of forklifts causes a loss of time, no customer will ever buy those forklifts, and they will avoid your entire company, and encourage others to not buy your forklifts.
>>2015529They are inherently valuable, unlike a consumer automobile (worst "investment" everyone in common life makes).And the eternal pressure of other business men not buying a liability of a dog piece of equipment, unlike the eternal sucker or the citizen consumer...But to be fair, forklifts are hothouse darlings of hyper primitive suite of simple machines in a supremely prepared use area. I worked in material handling corp, and they had a onsite museum as they sold forklifts. Shop too. I used to have to drive by hundred of these things off trucks. And every other kind of lift/electric floor jacks too. Loved that job but it was a career dead end.
