I guess I am odd man out. Yes there are many good ideas from a lot of owners that want their Spyder better for themselves. Obviously, if the idea goes into production it can be good for others too.
When I first read this topic a couple days back, my first idea was not something for me or our personal machine. After thinking more about it, I would like to see you get approval from or work with the guy from Scandinavia with the wheel chair carrier setup and help to let those with a dream to ride, possibly see the dream come true.
I watched the video here about the wheelchair carrier. Smiled a lot to see desire overcome a setback.
Watched TV, ans saw on Counting Cars, how "the count" I think his name is Danny, had his crew build a Spyder for a vertically challenged person. The person always wanted to ride a motorcycle but could not since it would simply fall over as his feet could not touch the ground. He bought a Spyder and they modded it so he could ride.
I have been fortunate to ride bicycles, pull rope mini bikes, dirt bikes, and even raced dirt bikes since I was young. My wife and I own a Spyder mainly for her, since she is not into two wheeled moto travel.
I have seen with my wife, and watched others I don't know smile from ear to ear because they get to enjoy something we already know. Riding.
So, yes, I would enjoy seeing you help by offering a wheelchair carrier, and secondly offering a bolt on setup to allow shorter riders including very short people enjoy riding if they want and funds allow it.
Sorry for the long post.
