building a tandem trike-need advice
so i am still in the design phase of this project. my basic idea is to get two vintage ladies' frames and weld them together side-by-side, keeping the rear wheels as is, and putting a fork between them for the single front wheel. i figure that besides the two whole frames, i'll need a couple of others to cut up and get the tubes for connecting the frames. my question is, what kind of bikes would be best suited for this project? i'd like them to be commonly found so that i can get them easily, and for cheap. also, i need to consider the frame material so that the pieces will be easily welded together. and as i said, i want the whole frames to be womens' frames. any help/advice would be appreciated. i'm really excited about this idea and have had tons of fun already just with drawing design pictures. :D

Unless you have done some investigatin...i think you will want to keep the 2 front wheels...only one in frnt may be a little tippy on the corners, just my 2cents. to answer your question about what kind of bike, I'd look for mountain bikes...more weight maybe but stronger?

Sounds like a worthy project. Just keep in mind that triangles are much stronger than squares. So you want to be sure to triangulate that front wheel into place. If you had a third bike, you could use it for the front, the other two for the side by side riders then gotta come up with a tie rod to connect one riders handle bars to the front bike. OR you could the sidecar version with one fairly normal bike with another attached to the side with no steering. Great fun!

Worksman makes a tandem trike with single front wheel. If you look at it, you'll notice that the riders sit over the rear axle, with the rear wheels outside the riders, and then the single front wheel is quite a bit in front. I'm sure this would contribute to the stability quite a bit.
I'd say in your case, the challenge would be to find two old-but-identical bikes. I'd suggest to try to get some old 3-speeds which don't seem too uncommon or two pricey. Possibly also Schwinn Varsities, which are similarly common and cheap. |
Maybe Jimbooth has a good idea in the "sidecar" idea in that it would not matter so much if the bikes were the same kind unless you are looking for symmetry... ?Are you looking to do more of a recumbent position or DF frame?

Then some durned fools would want to take them in the boonies:roflmao2: Oh, well...search for 'picnic bike' or someting like that on You Tube. They did something like this and made some videos. |
