Thus the Bus Bike was born.
I used nine bicycles, cutting and welding them into three single-speed triple bikes, then welding bars accross them, and finally connecting the three handle bars in an english steering setup.
It was pretty straight forward and turned and rode surprisingly well. With nine riders it was akin to a train. Very fast, very powerful and very difficult to stop.
i hand built six wheels for it, using double gauge spokes, rims, and hubs, and put single speed bmx freewheels on the back.
I ended up taking this to burning man and all of the wheels eventually taco'd.
Foreseeing this possibility i brought innumerable extras and thanks to the rugedness and universality of the design was able to throw random wheels on where ever they were needed. I did find however that single speed coaster brakes should not be attached because of the riders desire to back-pedal constantly.
I used a standard 110 mig for this project, be careful to grind away all paint when making the connections.
Materials included, bikes (9+ extras for donor parts), around 40' 1.5" steel tubing, lots of wire feed, lots of grinding disks, saws-all blades, paint.
I found a saws-all really came in handy for chopping up the bikes and rounding out the connection points, pre-weld.
Step 1: Get your materials
not just the obvious nine, but a least half again more for scavenging parts.
i used all new chains, and built all new wheels, but you definitely don't need to do that. The wheels ended up breaking anyway, and the chains were just so that they were all the same kind and saved time.
your going to need a bunch of steel tubing.
your going to need a lot of disposables, ie: grinding wheels, saws-all blades, and wire feed.
thats really about it.
