For now I am using a ongaurd lock from walmart but it doesn't feel entirely that safe. What do you recommend? What do you use?

I use two locks, a coiled Masterlock cable and a Kryptonite Evolution 2 U-Lock. I lock the frame to (something) with the Evolution and then loop the cable through the wheels and frame and the (something). I've had the Evolution for 10+years, maybe it's getting old - but I still have my bike! Use a cable and a U-lock because people that have the tools to break the U cannot cut the cable, and people that can cut the cable won't be able to break the U. Unless someone wants your bike so badly they carry a lot of tools!

Nearly the same for me, I use a Kryptonite U-lock (medium size) and an OnGuard coiled cable lock.

Every lock has its weakness, but two locks of a different design require more than one tool if the thief is trying to be speedy.

I use a Kryptonite evolution mini u-lock for the front wheel and frame and a small abus chain for the back wheel and saddle.

1. Kryptonite U-lock with rotary combination through the rear wheel and frame (comes in handy when I forget my keys).

2. Master U-lock with flat key through the frame.

3. Brinks mini-U-lock with cylindrical key and 5/8" cable through both wheels and the frame.

I leave them all on the rack at work so I don't carry them around.

I don't feel like I can tell much difference between U-locks.

I've got an OnGuard Pitbull that I leave on the rack at work. It started jamming after a couple of years (exposed to the weather constantly), but I oiled it and it's been fine for a year since. It's absurdly heavy, but since I don't carry it around that doesn't matter. The cover that slides over the keyhole seems like a nice feature. I also have a 5-year old Kryptonite of some sort and a Kryptonite-made Trek Streetwise. The Kryptonite gives me trouble sometimes with the rubber ring that holds the bracket attachment coming off. I have no complaints about the Trek Streetwise. It's light, doesn't fall apart and has a keyhole cover.

TiGr. Secure, easy to stow, locks both wheels without removing eiher, color-coordinates with titanium frames, under a pound.

I live in Chicago where they have professional bike thieves. I use a Kryptonite NY U-Lock & feel safe. I read a study that it would take about 10min with a angle grinder to saw off both sides. I plan on getting a BikeRegistry chain with the upgraded Abus padlock to make it more secure. My bike is 8 years old & I made it look ugly to look less attractive.

I am funny-style, and cheap. Not only that, my bikes don't even cost that much. With that said, I use a home-depot $5.99 combination-cable lock. The trick is, the bikes are NEVER out of my sight!! When I commute to work, I stop and eat breakfast at a Panera Bread. There is a railing about 5 yards from my table. I lock my bike with the cable lock, but I got eyeball on it all the time. When I get to work (at a college), I take my bike inside with me and it sets in a locked storeroom right next to my cube.

I am never going to lock up my bike and let it be out of sight, even my cheapos.. .. I had one bike stolen, it was locked, and I was lucky to have it recovered. When I have to go into a store, the bike comes with me..Like I said, I am funny-style and parinoid..

I use an Abus ring lock and chain:

I've got a Kryptonite New York lock and a 7' threaded cable that I run through both wheels and connect to the lock. The bike rack I use is in a pretty visible location near a door with a security camera that is continuously monitored, so I feel pretty safe. My two main commuting bikes are worth more than $2,000 so I feel that I need a good locking system. I never leave my bikes unattended overnight. I keep my lock and cable attached to the rack at night so I don't have to lug them back and forth, but I keep a small cable lock in my seat bag in case I have to make a quick stop while riding.

I live in Chicago so a good lock is mandatory. I use the OnGuard Bulldog U-Lock to secure my bike frame and rear wheel along with a Kryptonite chain and lock (not the monster chain, the smaller version) to lock down my front wheels. So far the lock has survived two known attempts to break it. The perps beat the hell out of the housing, but the lock held.


Current: 2005 Jamis Ventura Elite, 1993 Solid fork Trek 930/4130/flat bars/upgraded saddle - my fav between bikes and back-up bike, 1970s 3 sp Schwinn with fenders and rear rack - errand and wet weather bike

Recent past: 2008 KHS Urban-X - really nice commuter bike (fenders and rear rack) that survived several attempts to steal it when left overnight in downtown Chicago.

Current short list for Jamis replacement: Bianchi Volpe, Surly Pacer, Masi Vincere or Masi CX

The ART Foundation and Sold Secure both independently test locks for the insurance industry. I use locks that are rated both Four Star by ART and Gold by Sold Secure. These are top of the line bicycle locks.

Is the TiGr available yet to those who didn't contribute?

I currently use just a Kryptonite Evolution Mini U-lock, but my bike is in a very secure location. I plan on upgrading to Pinhead skewers to protect my wheels and getting another U-lock, probably the NY. Cables don't seem to do anything but keep people honest, but I figure most thieves will think twice about two U-locks.

What does everyone else think?

My preferred lock? None. I find them to be a pita... When I was kid we literally leaned our bikes against a tree in our front yards. No problem. Until there was. Times have changed.

What do I use? An Onshield Ulock and a master lock with a cable. For a quickie, coffee at McDonalds, I usually just use the masterlock and cable. At work the bike is in a room near my desk. At school, I use both locks. Last year my previous bike, locked with a master lock and cable, under the schools security cameras, was gone when I left class. Security showed me their video. After the sun set you couldn't see diddly. Yeh, I was pissed! The guard said to get one of those "U thingies, nobody steals those bikes." I went to the LBS and got one. So far so good.

Presently, I'm also using a Wally OnGuard U-lock, and a Brinks cable (12mm x 9'). Our town is pretty mild, so it's plenty. BUT. . . .

I'm looking at a motorcycle U-lock and a 9/16 x 6' cable with integrated lock for truck trailers; NOBODY'S getting my SC Butcher without a fight!

EDIT: locolobo, my 'innocence' on bike safety was demolished in 1976, when I loaned my Schwinn 10-speed to my best friend, and HIS COUSIN stole the thing off my buddy's back porch! My buddy made it good with me, and took it out of his cousin's hide....

My 19-y-o nephew was 10 when he lost his; he dropped his bike on the sidewalk in front of the house, literally 20 feet from the front door, to run inside for a moment; before he could get to the door, an older boy from the 'hood was straddling it, staring and daring him to do something. Never saw that bike again.

I like the AXA ring lock and chain , its got a little longer chain than #10 has , [1.4M]
so It includes both wheels and around something solid too.

Right now I am using a wal-mart lock. I just watched the videos about the TiGr lock and I want to buy one, but I couldn't find a place that sells them, including the website.

Which OnGuard lock do you have? I've been using an OnGuard cable for years now, along with a Master U-bolt lock.

That's why I carry two locks as well. I figure that most bike thefts are a crime of convenience, i.e. they're someone at the mall, store, park, school, etc. who is too lazy to walk home and are looking for an easy way to get home. Or they're a junkie looking for something that they can "fence" easily to get their next fix. And therefore they're likely to only have the tools that they need to defeat one type of lock.

The only thieves that'll have the tools to defeat multiple locks will be the "pro" and sadly those we can't really do anything to protect ourselves from as they are determined to get what they want.

Should be soon - the December 16th kickstarter update said all of the US locks had shipped.

I like my Kryptonite Evolution Mini U lock; it's probably about as secure as you can get without a considerable amount more weight, and it fits in my back jeans pocket (which is my preference if I'm just running errands). My touring bike has a pitlock skewer and headset cap, and on my cyclocross bike I just run a kryptoflex cable to the front, although this could probably be cut with scissors. I lock with the Sheldon method (U lock the rear wheel through the rear triangle) because I'd honestly be a little surprised if any thief bothered to destroy my rear wheel to steal my bike. If they're prepared to do that they'll probably just defeat the lock itself.

The TiGr lock looks good, if the feedback is still good a few months from now I'll look into it. It's new/different and probably more secure from thieves for that reason alone, beyond any actual properties of the lock.

That's what's cool about living in El Paso, TX - a city with little to no bike culture. People here don't know the difference between a Wally BSO and a $5000 Pinerello, and there are no pro bike thieves - there's no market and not a lot of bikes available if you're prowling. Nobody wants my middle-of-the-road Trek mountain bike except the "crime of convenience" that you mention - and my locks are bigger than those people. Viva El Paso!

+1 AXA Defender Ring locks on two of my bikes, I have one chain which moves between bikes.....
