That's how we did one.
It went quick.

I've seen one of those side-by-side tandems in use. Looked like they had no trouble at all riding it, but I'm guessing they had quite a bit of practice.

Re: Bike Security
I've come to love the method of putting a bungee on the back tire connected to the frame. As effective as a lock, and the comedy of watching someone try to ride it is priceless. A decent bungee will let the wheel rotate about 3 times before it stops, and will pull the bike backwards as soon as they stop pedaling.

When I ask how many burns, I mean at BRC.

Re: Bike Security
Hooked up the loose bits and tried riding this thing today. No bleeping way! I cannot even walk it along. And the really funny part is, as soon as things start going the wrong way, the natural reaction is to “try harder”, and that snowballs in something like 0.00003 second. So I find myself unable to make “a small mistake” with this thing. Sometimes I’m lucky for a few feet, but then the crash is total and absolute, instantly. The bike goes to one side, and I go to the other. Mission accomplished!





Re: Bike Security
If your paparazzi skills are half as good as your mechanical skills, will you please post the pics of would be bikenappers crashing for us after the burn? Awesome work, should be good for many belly laughs. 19 thumbs up!

No, it's not a bait bike. It's a bicycle with non-conformist steering... for those non-conformists who wish to experience the freedom of taking someone else's ride, they get a ride free of conformist steering!

(just watch. some psycho who's never managed to ride a bike in his life will hop on and wiz around the playa in joy!)
(looks 1:1. Optical? as 15 degrees left gives a wheel 15 degrees right, for 30 degrees between them?)

A single gear was cut in half and flipped inside out. So yes, that is an exact 1:1 counter steer.Canoe wrote:(looks 1:1. Optical? as 15 degrees left gives a wheel 15 degrees right, for 30 degrees between them?)
And I just had a moment of inspiration, what about a bike with spring brakes? IE, pulling the lever actually releases the brake, and letting it go allows the spring to engage the shoes. Looking at the rear brake on my bike it would be totally possible with the side pull cantilevers it has. Just take the cable off, add a drum brake spring in its place, and cut four small sections of 1/8"x1/2" bar, rob the adjuster and nut off an old side pull brake and make sort of a center pull scissor jack to stretch the spring. Make me wish I had facility and spare parts to toy with the idea.

Re: Bike Security
What's nice about that idea is that the immobility of the bike would immediately make the bike undesirable even before the person took time to figure out how to tape up or use the brakes. It's like disengaging the chain so somebody has to monkey around and fix the bike.Thorormr wrote:And I just had a moment of inspiration, what about a bike with spring brakes?

I still like the counter-rotating steering though, because it's just so off-the-wall, not just an immobilization tactic.

Re: Bike Security
Thor, that's a fabulous idea. And the "scissor" mechanism to release it. You have it all designed!
I can add only one suggestion: The brake lever can perhaps be modified so it has a "catch" to keep it pulled in, so the hand muscles do not cramp up while riding.
So who's building it?
Incidentally, big trucks and buses with pneumatic brake systems have such spring-loaded parking brakes to keep the vehicle secure even if all the compressed air leaks out while the vehicle is parked. Likewise, if a major leak occurs while driving, the spring brakes come on by themselves.

Re: Bike Security
For a lever with a catch, I am remembering a trike one of my grandmother's had, the brake lever had a spring loaded pin in the housing that would hold the brake until you squeezed the lever. Then the pin would pop back up and the lever could be fully released.Elliot wrote:Thor, that's a fabulous idea. And the "scissor" mechanism to release it. You have it all designed!

And the spring brake idea was inspired by truck parking brakes. Shoot it could even become a safety device for a bicycle with a motor adapted of some kind. Kind of a deadman, if you fall off the seat the brake comes on.
I'd love to get into making this stuff, I just don't have the facility or spare bits to cannibalize.

Re: Bike Security
I just saw this:

Water bottle shape to fit in the bottle cage. Self recoiling keyed 8mm cable lock, stash box in the bottom, comes in black, white, pink and red/yellow/green. Long enough to go through both tires.
