Hello to everyone. I'm in the early process of building a little project and was looking for a little guidance from some of you.
I attend a fun little annual gathering out in the desert every year, and there is a lot of neat concept art type vehicles there. One of the people I went out there with this past year had built a pretty cool "Art Bike" using 3 standard bicycles. 1 on either side, and 1/2 of a bike on the back center, with a small platform in the middle.. Platform dimensions are roughly 32" W x 48" L with a wheel base width of roughly 50.5" on center. It had a extra seat in the middle for a passenger, and space on it for a cooler or other misc items... Anyway, it was a lot of fun to ride around on out there with friends. Here is a picture of what it looked like. Some of you can probably guess where it was taken and what I'm event I'm talking about. 8-) Here's another pic of it right as it was done being built. So after cruising around out there for a week with it, I really got to thinking about building a similar one myself. The size of the one he had worked great, but I think it could be a little bigger still. So I was thinking about replacing the side bikes with a pair of tandems, which would allow me to extend the platform a little more. Might go a little wider also.
So my question for you fine people here is: Do you have a recommendation for a cheap, durable steel tandem bike? It would need to be steel so I could weld the connections on for the center platform. The terrain out where it will be ridden is perfectly flat, and hard like asphalt so gearing isn't a real issue. In fact it would probably be better if it was a single speed. Big wheels would be a plus as it can get bumpy in spots, and there is the occasional small sand dune you need to muscle through. I'm probably going to keep the rear center 1/2 bike in my plan, but add a electric hub to it as well to give the whole contraption a little extra "push". So who knows of a good candidate bike or bike frame that would possibly work? Any suggestions?
Thanks in advance!
/edit I say durable in the sense that it would not only have to hold your standard pair of riders, but also the weight of the platform, extra passengers, cooler, etc etc... Of course this weight would be spread more or less evenly over the 4 connections to the 2 tandom bikes on either side, with a little weight also taken by the rear 1/2 of a bike on the back of the platform as well.
/double edit Bonus points if the pedals are free spinning, so everyones feet don't have to be moving/pedaling at the same time.
