As i stumble into unemployment again, i've gotten the absurd idea of selling my car and getting an ebike and work locally in my area. Considering i haven't bike in so long, i figured i might as well invest into an ebike, but considering the unknown reputation these things have, is it worth getting one or am i better off getting a traditional bike?

I actually just got to the point of the 15% cheaper energy from the wall calculation, then I tried to come up with "but actually a human is more efficient at putting the energy into miles" though I wasn't able to make that argument. I went as far as finding a source that says humans use 218 watts to travel 20.3mph (which is the speed that ebikes are limited here) or 262w to travel 21.9mph, and 250w ebike motors can reach 20mph (and would go faster if they weren't capped) which implies a very similar usage of watt hours per mile, however I couldn't find any hard data for the ebike at a specific speed. In any case, a real human is not getting calories by chugging corn oil, so he's probably like 10x less cost efficient than an ebike if he has a normal diet. I forgot to consider waste of electricity during the charging or whatever but I doubt it's anything near this.

On the other hand, you can consider calories to be free in the sense that most people desire to eat way more than their body needs for their normal activities, and the cost they spend on the food is primarily for the taste and social elements of eating. Most people would physically enjoy the act of eating extra food and would find this to be worth the money in and of itself as long as it didn't make them fat. So in that sense, the cost of consuming additional calories for your bike can actually be considered less than free because the act of consuming the calories provides surplus pleasure.
A huge amount of motorcyclists in the United States are unlicenced. Cops never pull over motorcycles or scooters and they don't care
You sound gay.
yeah where i'm at anything over 49cc requires a license. i could see how that would be a deal breaker for some people. i still have a hardtail mtb with a bafang bbshd on it at 52v, so i would recommend that combo too.
this has been true in my short experience. cops do not seem to see the scooter so far.
No, no no no my friend
a human is way ways more inefficient. Thing more akin to the average efficiency of an internal combistion motors across all of its load-speed conditions than the electric system. The later is or can be very efficient if you don't completely fuck up (like brushed motors governed by some linear regulator.
In other words: Any 'cost' (be it environment or monetary etc.) of wall power being less than 3x that of food and it's already no contest.

I found something neat on Craigslist, 24" gauge tracks and a small locomotive from a mine but the seller doesn't know much about them as they belonged to his dad previously. At $75 a track I really like the idea of having a 120ft oval loop around my backyard.

Can anyone help me compute just how much track I need to pull this off, especially with the curves? I really have no experience with anything bigger than some model trains on this.

holy fuck buy it, there is no shame in a non looping layout. you can always expand, but a good deal is an opportunity
You should go to the seller and try to lift one of those sections of track by yourself OP
are there any sections used for interchanges? because if so you could try to rig something up where you go on one track to the end, go in reverse and change tracks for the return.
>120ft oval loop

How do you guys learn to repair your bike? I've been a daily commute biker for over 5 years and I don't know how to do any repairs except the extremely most basic shit (replacing rim brake pads, flat repair) because I have no way to learn or practice since I only have my one bike, and I'm not gonna fuck up my own bike trying some unnecessary repair. I have never really had any significant issues

no the green bike is just sitting around atm
it weighs a tonne even by steel standards so its not really worth doing much to
i have plans for it though
the perfect bike for me is a very personal thing
i just want to choose every component of my bike so the whole thing fits my preferences perfectly
and its thanks to both of these pieces of shit that i learned how to achieve that
now i cant even imagine just buying a bike and riding it and accepting things i dont like knowing that i can swap any component for any other
By asking what your perfect bike is I meant in terms of components not your philosophy on the subject although I do appreciate your answer. As in what style of frame and so on.

>its not really worth doing much to
>i have plans for it though
I know the feeling. I've also got an old steel mtb which weighs more than its worth but it's hard to fight that urge to make it just that little bit nicer.

well this is the steel frame and fork i bought
those wheels arent the ones im gonna use those are just for show
i kinda cba to explain every component im gonna use tho
i have my preferences for almost every individual component at this point
>it's hard to fight that urge to make it just that little bit nicer.
yeah its very tempting but i know im not gonna ride it unless something goes catastrophically wrong with every other bike ive got
how is it consooming if it's cheaper than paying for somebody else to repair your bike? the only tool i've gotten so far that isn't in a standard home toolbox is a spoke tool for 2 bucks.
i have a buddy who fixes bikes

So... im new here, i was planning buying an electric scooter just to do little tasks like going to the store but they are expensive and look gay, someone recommend me this board, i have a very retard doubt, why and when you change gears on the bike? They are faster than fixies? Im currently driving my beloved tweaker BMX
you change when the teeth are sharktoothed
usually this can be delayed if you replace chain before too much stretch
You use gears to get more torque out of you pedals. Meaning you have to use less force to get up a hill.
World hour speed record was set by a fixie.
if it's flat where you live, a single gear ratio might be all you need. but the ratio that comes with the bike may not be what someone with your weight and strength wants to push, but you can tune it by changing out what you have.
multiple gears let you spin an easy ratio to start and then gradually work to faster speeds when they spin easily enough to switch to a more difficult ratio. they really come in handy for climbing up hills. instead of mashing a fast ratio, you downshift to an easier ratio and spin uphill. a "slower" ratio spun fast can actually be faster on a climb than a "fast" ratio spun like going through molasses, and you can hunt for the gear that you like best for any particular terrain.
Very obviously your body, your legs and ass have an optimum for power delivery, force production and endurance.
Suppose you pushed on the pedal of a bike that was geared arbitarily high. You'd produce the maximum of force you are capable of producing but you can not do so for long and, unless you're able to produce more force, you wont get that thing spinning and thus power output will remain low.
Suppose the opposite: The gearing is arbitarily low. Your muscles can only produce force up to a certain speed. In fact you can only produce that maximum force determined in the first thought experiment up to a certain speed, after ehich it will drop. Also when spinning out you're utilizing alot of power merely to reverse the momentum in your legs.
At last on a bike with sensible gearing you'll be able to produce a force far from your physiological maximum but one that your fatigue resistant muscle fibers alone can peoduce. You'll be able to produce this force for possibly many revolutions per unit of time, thus increasing power, without wasting too much power on reversing the motion of your legs.
Now if the gradient shifts or wind changes your effective gear ratio changes. Which is why you want to be able to change gears.
You should, when riding, aim to be riding at a cadence at which you can produce the highest power possible, for indefinately long. Choose the gear accordingly. Do not mash unless specifically wanting to do so and understanding why. Also do not spin out, which you wont do, no one volutarely spins out.

I want to buy a road bike and go for some nice long, exploratory road riding but things like this confuse the fuck out of me and worry me especially if I don't plan the trip.

>wait for the light, go straight to the other corner and stop, then turn your bike and put it in the bike lane to go the next direction, wait for the light and go straight again
That's called a hook turn and it's what the government says to do but I've never seen anyone do it
Would you fully do it like this and just join the other lane at the crossing?
I suppose so, if the bike lane wasn't against the curb.
I like going all the way to curb though, because I wedge my front wheel into the curb and lift the rear end of the bike to turn it to the new direction, like a fulcrum and lever. Maybe that's less of an issue if you're a roadie though? I carry a large pannier so the bike is kinda annoying to lift.
Still, the "proper left" where you use the turning lane (or I guess "proper right" in AUS) is way more comfy if traffic conditions allow for it. Probably why you've rarely seen hook turns.
Road riding is not nice, for the simple fact that you have to share the road with cars.
1. Rule of cycling: You go. Motorcripples are fucking stupid degenerates and have to wait. If they hit you it's their fault and they are liable. After all they do enough operating a murdercage alone and they are very aware of associated risks and still decide to do so.
2. You turn left on your green or at will as long as no pedestrian is crossing the lane youre turning into. Also watch out for homosexual cyclists and 'e-bike' fags on the cycling lane. Ruins your day when turning left.
3. You go straight on green or at will.
4. You ONLY turn right if no one coming your way wants to go straight or (their) left.
5. If someone coming your way wants to go (their) right you both turn right infront of each other.
6. If crosswalks are present let pedestrians cross.
7. A bicycle is not a pedestrian. It ha sno business on sidewalks or crosswalks.
8. If several parallel lanes are presentmake lane changes according to your wishes to go any direction at the intersection. Wanna go left then start by sticking to the left. Do not cut right across infront of everybode else.
9. Remember you're representing cyclists. If you spot any motorist including 'e-bike' forget all of the above, give chase and overtake.
You got this man.
I don't know, occasionally cars are fun. I love the smug feeling of cruising past a big line of traffic, or getting in just the right spot for a cheeky draft. The worst thing is the noise honestly, when lots of cars are passing at high speed they drown out my music

What's the train supposed to do in this situation, when there's no huge accident? I mean it's not like it slowed down a lot due to the impact, so it'll take a while to stop, by then it'll already be quite far away from the car.
I mean it's kinda the same as if it hit some animal or even a person, there's really not much you can do, so do they just keep on going and report it or whatever?
Probably just stop anyways.
You can't really assess the damage from inside the train. You wouldn't want to keep going and then discover a hydraulic system is slow leaking or a shorted wire has electrified the frame of the locomotive or something.
That and why finish your shift? "Stress leave" starts as soon as you finish the police report.
>t. not an actual engineer and just making shit up
Stop and report an accident as you would in a car.
It'd be a hit and run otherwise bro.
