Thankfully with a little creativity, some fancy welding work, and a pretty good sense of humor, the modified, uber, epic, mega lock was born!

Signing UpStep 1: Things you're gonna need
- U Lock (we used an Onguard Bulldog 5006 Pitbulll Mini Series Lock- retailed $45)
- MIG Welder**
- Cut Off Wheel
- Angle Grinder (24 grit grinding disc)
- Two metal rods cut to desired length. We used hardened steel at 40" in length; long enough to lock up 4 bikes. (be sure that the diameter of the rods are the same or close to that of the original lock)
- Vice Grips
- Plastic accordion tubing
- Spray Paint
**If you don't own a MIG Welder (gasp!) and live in the SF Bay Area, near Detroit, MI, or Raleigh, NC, don't fret. You can use the welder at the Tech Shop! ***

Having said that there is no padlock like device that will stand up to two minutes of attack if a thief knows what he is doing. One answer is long prison sentences for the first instance of bicycle theft. Knowing that stealing a bicycle will be a life ruining experience will tend to stop most sane people from such a crime. Thieves are the greatest obstacle in getting people to use bicycles and not use cars. The theft of a bike is actually an assault upon all of society. It is in effect, a form of terrorism that alters society just as bombs and bullets do. Matter of fact more people die in bicycle thefts than in bank robberies. It is a serious crime but treated as a joke by the law.
we do use two types of locks for this set up (modified lock, and a cable lock). We also installed a motion sensor flood light right above the bikes. I want to attach a red LED light to it as well for added funsies. Then when the light goes off, and the potential perps see the little red LED, they think its a camera attachment as well.
Add it to the laundry list of "To Do" Projects in my house. :D
This is a question for the welder, wouldn't it be better to cut the stock on a matching bias and at different spots on the length and then weld them for a stronger joint? It seems you have hardened steel that just meets up at a point and then you fill in with weaker welding metal. It would probably be easier to just crack and snap the joints if they saw the weld.
I guess you could have the welding points at different spots to prevent someone trying to snap or crack at the joint, but if someone came in, ripped the tubing off, snapped giant rods of steel, took four bikes, jumped over my fence with them, and then rode off into the sunset... bravo! They deserve the bikes at that point! That is dedication hahaha
As I work with a cycle-taxi company, sometimes we have to retrieve stolen taxis or hotel rental bikes. So we have a battery-powered mini circular saw with steel cutting blade. Goes through the same kind of metal locks and steel in about 20-30 seconds on average.
Saw: $300 USD (average)
3 bikes: $300-$500 each for the cheap ones (average)
profit: $600-$1000 and the saw pays for itself on the first useage.
Indoors or in a locked garage is usually the better 'addition' to make it harder to steal. Can always hang the bikes from a wall or ceiling if you need space - and can become 'wall art' ! :-)
My interest for commenting is your headline and last photo that shows three bikes vertically mounted, how? Is this some propriety device you can point me at or do you need to write me another instructable ;-) Al
As for the bike rack, you are in luck! Good old fashioned store bought rack that bolts into the studs on your wall. We have these at the Instructables HQ also.
The one I have is made by rubbermaid, and you can probably just google "Rubbermaid vertical bike rack" and see what pops up!
Good luck and thanks for checking out my i'ble!
Nice work, 5*.
Personally I use a piece of snig chain on my bike stash. The chain passes through two holes in the wall then fastened by a decent padlock which is inside the garage.
8mm snig chain could be cut but not in reasonable time by hand-tools.
I've found that the more cool stuff on a bike the more likely it is to walk off. So if you don't *need* a drink cage and front shocks, etc then don't have them.
Quick release anything is just asking to be quick-released.
Black bikes are more stealable than coloured bikes. Clean and shiny bikes are worse than beaten up ones.
So my bike has a scummy looking water-damaged cardboard on a carrier instead of a flash mudguard/fender. It has no flash light fittings permanently attached. The handle grips are crappy foam. But the bearings are perfect, rims are true, brakes work stunningly, and the tyres are properly inflated.
I'm about one more bike steal away from just hiring someone to stand in my bike yard.
Are you sure the overall security still holds?
I'm a bit paranoid about bike theft... you know... so I've studied it a bit on Youtube.
Looks like 99% of thefts are just of opportunity.
Anyway those U Locks can be easylly (and silently) broken with a portable car-jack: put between bars and lift...
The only "safer" (never 100%) way seems to be to use 3 different locks (like : cable + ulock + chain) so that the thief must have 3 different sets of tools... unlikely.
Happy Ridings !!
