Listen faggot,

You think you can advertise your shitty business on 4chan for FREE? LOL, no, you have to PAY to do that here -- and we're not interested in your shitty products anyway. So how about you fuck the fuck off?

Reported, saged.

>ask for feedback
>advertising

Yeah I'm not seeing the connection.

like you are going to approach the thief and say "give bike back please sir"
yeah that will surely do

first of all, yes your new bike is gonna be stolen too. The time it takes is up to you but you should take note of these tips if you want it to last longer:
>cheap bike so they don't want to steal it or so your loss isn't a big deal
>Two hardened chains or U locks so your lock both wheels to the frame and both chains to a secure spot. This may cost more than the bike itself but don't go too cheap here.
>be sure the padlocks aren't of a dented or tubular key. Don't buy expensive padlocks, but the sturdy ones with plain keys for rotatory slits.
>ABUS bordo locks a shit
>Don't use removable bolts

Now, a good gps tracker is not going to be cheap plus you need a SIM card with data, you could check Freedompop's free data plan for that.
But you shouldn't get one. Trying to retrieve goods from bad people is dangerous as well and police would probably do nothing unless the bike is worth the effort of the bureaucracy behind it.

write down your serial number and fetch the fuzz

If you have a bike but not a car, you are either a hipster who works at an organic food co-op or a NEET. I have a bike and a car and wouldn't want to go without either. Both do things that the other can't.

>>1019216
The idea is that we should try to shift toward cities and urban environments where one could very reasonably live with just a bike and no car, instead of resigning ourselves to being dependent on cars because "that's just how it is."

i live 1 hour from town.

my driveway is 2 miles long.

you need cars where i live.

now if i lived in town id just cruise everywhere comfy bike life

It's less about aero and more about comfort, particularly the shorts.

>>1018512
The padding in cycling shorts is important for comfort if you're going to be spending more than 2-3 hours in the saddle at a time.

Cycling jerseys have pockets that you can stash food in; also important for multi-hour rides.

Neither matter if you're topping out at 25 mile rides.

>>1018514
Mandatory if rainy. Otherwise you can always ride comfortably without them.

get a fucking dutch bike.

Looks like exactly the same thing. Okay then let's rephrase the question to what are the pros and cons of such a design

The big disadvantage of a step thru is lower frame stiffness. Many of them are heavier, too. Losing the double triangle causes a lot of compromises in the structure of the bike. That's why mixtes are great. They retain the double triangle, so you get most of the advantages of a step thru but with a stiffer and lighter frame.

It's hard to find a new drop-bar mixte in the US these days (most are flat bar grip shift with IGHs), but there are lots of old Peugeot and Shogun mixtes still around. New, you can build up a Soma Buena Vista if you have a decent budget. If you don't mind flat bar grip shift heavy flexy, Linus makes an okay mixte.

buy a fucking car or use the metro

Costs more

Not like I'm moving house by bike I just want easier and fewer grocery trips and be able to travel without my backpack on due to how sweaty I am when I get where I'm going

Nah, they're great. Just make sure it's firmly attached to your rack and you're good to go. It will break after some time though, good thing they're everywhere and for free

>>1019621
Is it required by law in your area? If not you never need to wear it but can I'd you would like

>>1019621
On my country if you leave city/village roads, you must wear a helmet, and if you are 16 or under 16, you must wear a helmet always.
I like wearing helmets, they give me fred status and makes me different to the plebs.

>>1019621
Broadly speaking, its totally up to you. If you want to risk your head you can, but I don't see any good reason not to wear a helmet.

I agree

this won't help when you fall on your face and hit your chin/nose on the asphalt.

Dry forehead and wind in my hair?

Yes

and this is what I mean by the bus arm. Could it stabilize the front wheel if you can't get it past the front rack stays? Can it be used on the rear wheel instead?

This 'basket' can't hold small items without secondary containment, while also being able to carry less wide things than a normal front flat 'rack'.

I've had one before, the stays are very weak, and I hate the hangars over the handlebars.

Where did you leave it and how long?

>>1017887
I have, but only because I lived in a small town and was lucky. You'll probably never find your bike, mate.

And nope, unless it's a very flashy bike (with a weird frame) or you put a gps or some shit like that inside the frame, they won't help, especially in a big city where bike thieves are commons.

Might be a good idea to file a police report if you're planning on getting a new bike paid for by your insurance.

Op triggered because people ride saddles that cost more than his bike.

Space blimps when?

Tram lines don't usually use the railway-like traffic control technology, that's one of the main factors that make tram a tram. That means there is no real thing like trains per hour at tram line. There are only theoretical numbers that say how much trams can still go thru a line without making it congested.

>branches and merging
most of the tram systems on the world work actually as a system, not several separated lines. That means there are dosens of branches and merging and junctions in every system. The most busy parts can serve then like one tram every minute. At least that's how it is in my city.

What does this mean? Thousan Per Hour? As in thousands of pax per hour?

You have to take into account how the maximum occupation of rail vehicles is calculated. Standard calculation is four people per square meters. Many specifications will calculate way more than that, which is a Tokyo-style crush load. Picture four people on one square meter, you're already breathing down the other persons neck. More than that is just madness. I'll get back to why I needed to explain this.

I can give you the specific numbers for Barcelona. We have a 2nd gen tram system with capacity for 60m long trams albeit it runs 30m trams that can be coupled together. Each tram has a capacity of 220 pax (seated, plus 4pax/m2 standing). The system is set up to run up to 20 trams/hr, which is one tram every 3 minutes (traffic light phases are 90 sec, so this would be one tram every other green light, this is considered the practical limit). The total is 8800 pax/hr.

Since you mentioned metro, I'll compare this to the municipal metro (there's a few lines that run on commuter systems and have different specs): This system runs 5 car trains, and the lines have no mergers nor intersections. Each train carries 700 pax, although many calculations will consider up to 1200 pax, which the manufacturer specifies as an exceptional (crush) load, which is why I insisted on how to calculate capacity first. This raises the pax/hr number about 70%. With 700 pax/train and 20 trains/hour you get a total of 14.000 pax/hr, not even twice that of the trams. With 1200 you'd get 24.000. At 30 trains/hr, the maximum possible frequency, you'd get 21.000 pax/hr. Of course this is a small-sized metro system.

trains per hour, not that hard to get it
