Looking through some locks and higher security ones usually are pretty heavy like 8-10 lbs for our 20ish lb bike. And lighter one tends to be suck. Or do you guys get a lock at all? Kryptonite New York U-lock seems pretty tough.

Mine must have been on sale because I got 2 for about 75$ total. But I use kryptonite. Dont buy the lock for it's bike coverage bs because that is pretty much just a selling gimic (lots of ways they get themselves out of it) but the lock is very study.

Mid-range mini U-locks are much lighter weight than the locks you mention and still give you a good amount of security against non-pro thieves. I use an OnGuard Bulldog Mini, but Kryptonite Series 2 is similar.

If you're locking up your bike for an extended period of time (at home or at work or at school), think about leaving a heavy duty lock at your destination so you don't have to carry it around with you.

My commuters get a thick cable lock, they're always in a place observed by security and not left all day. All the other bikes sleep inside

I bought a Kryptonite U-lock from Walmart for around $18 as soon as I got my bike. The shipping weight is 2.45 pounds but I live in an area where there are a lot of bike thefts, it'd be nearly impossible for someone to steal my bike by cutting through the lock, and it has the advantage of being big enough that you can lock two bikes around a pole with just the one lock.

Why? There are ways to cut through any lock. It may be noisy, it requires tools and a bit of time, but it's definitely doable. Do you mean your parking spots are otherwise secure (as in someone is guaranteed to intervene if they see a lock being cut)?

None. I don't use locks but I don't leave it out of my sight. Ever.

What do you do about bathroom breaks? I once had a restaurant owner in an unfamiliar town miles and miles away from home go ballistic on me for bringing my bike into the bathroom with me. Too bad I'll never return because the food was what dreams are made of.

I do my business outside, beside road, in the bushes or something.

Which is fine unless you're in a city, get caught doing your business, are arrested and have to register as a sex offender because you exposed yourself.

I'm kinda insane on this front.. I use one of these.

And two of these:

I should do some research on the Tigr lock now that they've been out in the real world for a year or so. The concept is great but I haven't followed up on it for how they are really working to secure a bike.

I don't lock my bikes up outside for any long periods. Mostly to grab a quick bite to eat during or after a ride.

I use a reasonably heavy-duty U-lock and a cable to loop through wheels if they have QR skewers and really only use this for short-term situations (running to the grocery store or the like). If it's going to be there all day without supervision (commuting), I'd do the same thing with a bike that I'm comfortable with losing.

+1. I have seen Kryptonite locks defeted with power grinders pretty qucikly. Also, there are other ways to defeat them besides cutting. With the right leverage and a sturdy tool, they can be pried open.

I use a TiGr lock. It's rare to carry it, not on training rides or typical riding fun. There are enough places locally where the bike doesn't have to leave eyesight.

But for some summer festivals, where I might ride sportively, and then park the bike. The TiGr lock sits unobtrusively along my top tube.

I use something very similar to this when I ride to work:

It's small and light, fits in a saddle bag and I don't need a key. But then, I'm fortunate in that the area where I park the bike at work is about as safe as you could hope for. It's far away from any public foot traffic, and right under a security guard shack window. The only folks who have occasion to wander by the bike rack there are my fellow employees. So all I need is something to keep honest people honest, as they say.

I haven't tried this yet, but I'm thinking I could use this to take a quick bio-break on a longer ride. I would guess it's probably just enough deterrent to prevent a random "crime of opportunity" bike theft in that situation.

This. You have to realize that no lock is theft-proof. That being said, you're looking to slow down the thief as much as possible.

I have a couple of Abus Bordo folding locks, which I like a lot. They're very portable, though some versions are lighter than others.

prathmann

I know a few people whose bike never left their sight until it disappeared around a corner with the thief on it. They were only a few feet away, but that was enough of a head start for the thief. We had a guy dressed as a cyclist who would frequent local coffee shops popular with cycling groups. He'd stroll by the parked bikes and wait for a good opportunity to grab one and ride off.

rebel1916

None. I pack a gat and never get further than 25 yards away from it.

TiGr titanium. Easy to stow, standard length locks both wheels without removing either, color-coordinates with titanium frames, 510g/1.1 pounds. I just leave it on my bike.

A three foot set of bolt cutters will go through one in five seconds

sort of like an angle grinder might go through a U-lock in three

although concealable little baby bolt cutters won't get it like a small cable lock

I only ride for leisure so I would never leave the bike for longer than it takes for me to go inside and buy something or go inside and take a pee. If possible I would never lose sight of the bike but sometimes I would take a dirt cheap lock I got from the supermarket bike section. It will not stand up to any serious attempt to break it but I would never be out of sight long enough for a serious attempt to be made without having enough time to rush out and give the bike thief a dose of woopasss.

Don't steal bikes bro! Not cool.

yamsyamsyams

if you can afford to, and are paranoid about losing your bike, keep it inside, never lock it outside. if you must lock it outside, make sure your bike doesn't look as nice as the others surrounding it!

I don't ride in the city.
