Calling all McGyvers

I know that there's some pretty damn ingenious people on this board. If that's you, then can I appeal to your inventive side? I am trying to solve an issue for months now, and I can't bring it together in my head. So, in the vain of "the more minds the better" approach here, can you give this some thought.....

The history- I have a buddy that rides. Ok, he rides a Kaw Vulcan b/c of reasons that you'll see as I explain....he needs all the leg reach/control advantage he can get. He ridden his whole life with the last ~15 years he has done so with a prosthetic leg on the shift side. (He's had his bike mod'ed so he can shift on the right side) He's said that there's been more than one time, he's gotten off center of gravity towards the left and does a slow topple. He jokes that with a wooden leg the bike doesn't hurt it when it falls on him, but I know it bugs him down deep.

2 years ago, I had a back surgery that left me with some nerve damage on the right side leg and now I wear a brace on my foot to help. Twice I've done a slow topple to the right b/c I couldn't control my leg the way I used to. Because of this, I've gotten a taste of what he must have to deal with, but much worse as he can't move his fake leg off the peg without doing so by lifting with his hands; and that's just not going to happen in the very short time it takes to topple. This got me to wondering...

I wondered if we could pre-load the kickstand with a spring that could be deployed at first "oh oh!". Maybe a "panic" button on the handlebar? A couple of my buddies kicked around some ideas, but kept running into roadblocks. The kickstand idea is ok, except it may not be able to be deployed quick enough. We also thought about a hydraulic telescoping stand, but that is getting more complicated. We also don't want to "pogo stick" him over the other side. The other issue we thought of was that the button would have to be readily accessible, but not accidentally hit. I could just see accidentally hitting the button at 50 and finding him in the ditch....a speed lock out of some sort? WE even thought of an airbag.

So, after a couple of months of dwelling on this, I'm at a standstill and could use some collective brain boost. So, here's what it needs to do-

1-keep him from toppling to the left/kickstand side
2- quickly deployed
3- the fix can't be more dangerous than a slow topple

Personally, I see this as a way for me to pay it forward, and maybe some of my Christmas sentimentality is showing here....would love to see others jump on this too. I also don't think my buddy is the only one this could be useful for. What do you say mates?

Re: Calling all McGyvers

Quite a while ago, I recall seeing an article on an LT that had been modified whereby some form of training wheels were deployed automatically when coming to a stop. I did a brief search on Youtube and this forum, but couldn't find the article again.

Another option would be to modify the bike into a 3-wheeler (Hannigan?). There is a female lawyer that frequents the Rock Store outside LA that rides a CanAm 3-wheeler specifically because she has mobility problems with one leg.

Good luck on finding a solution that meets your needs...

A friend of mine had the "training wheel" set up on either a Gold Wing or a Harley. Not sure exactly how it worked. I could find out more if requested. I think he still has the set up.

Re: Calling all McGyvers

I know the 'uh-oh' feeling - recent Lyme episode triggered lingering left knee issues. An LT weighs about 1/2 ton. Hmmm.

Wanting to keep riding, I took Can-Am up on a demo ride. Result, my black LT has been replaced by a black Spyder RT-S. Great trips already. Great in wind, rain, traffic, plus sand and/or gravel. Ok, I miss the leaning in corners, but the Spyder and I get along great. AND it does NOT fall over if I park in soft stuff! AND I have a new ryde to farkle!

Re: Calling all McGyvers

Yeah, I get the idea of going to 3 wheels, but his current rate of topples doesn't warrant that big of a change...yet. I was hoping to come up with something that can be added onto his existing ride in an effort towards keeping him on 2 wheels longer.

Re: Calling all McGyvers

Do a search for motorcycle landing gear. I found a couple of different versions that according to the article will do what you are looking for. What I don't know is how they would effect corning clearance while riding.

Idea passed along. They don't make one for his Vulcan, but I bet it can be mod'ed to fit. Thanks.

That is really cool! I wonder what generation they will be on when I need this system in 30 years... ok, maybe 25.

Ugly, but interesting. I've never heard of those before.

At $5,500 and ugly as can be...no thanks. I would go with a Spyder or maybe a Trike before these giant training wheels. It is a viable option though I guess.

Instead of these ghostwheels, you might as well go with a system like the one on the test bike for the Twist of the Wrist II movie. The bike can lean what would normally be past the point of no return but without actually falling over. You can see the system at about minute 16 on youtube.

Re: Calling all McGyvers

The MonoTracer is a two-wheel, single-track (okay, motorcycle) with an enclosed shell. The driver/rider sits inside the shell with a steering wheel. There is an electric version as well.

It has outboard side wheels that flip down when stopping.

Re: Calling all McGyvers

Yeah....Ghost Wheel is pretty durn ugly. Looks like a wheel barrow on each side. At least the landing gear looks like it can be somewhat obscure when in the up position.

Re: Calling all McGyvers

I predict a problem with the Leg Up for your friend's (emergency) Vulcan use: if he's not on flat ground, those things will tip him over one way or the other (ala the power center stand on my K12LT).

How does he retract the kickstand now? That info might help brainstorm a kickstand deployment device. I though of a system that would require the kickstand to be spring loaded to deploy when I realized that retracting against a significant spring force might not be possible.
