Motorised Tandem with sidecar.

Bugatti made a cyclemotor engine, or two to be precise..

underslung valved single cylinder motor with rootes type supercharger as standard models 72 & 72Bis but they werent ever put into production.

So far as I know there is one complete engine, that shows signs of having run, getting a chinese company to copy that would be somewhat interesting...

Now thats what is SO COOL!!! I recently saw something like that at an open resturaunt in Waldorph Germany, complete with side car, parked next to a vintage Bugatti car, the car had a parking ticket on the windshield, but not the bike

Well where would u put the ticket? Under the tire?
 
With what would one start to build a tandem out off? Are there any resonable priced bike frames available that would be strong enough? I would think that the wheels and brakes would need to be upgraded and could a springer front fork be added? Also, what engines would be adequate to have the torque needed to climb hills and what type of clutch? Top speed is not important - 15mph tops. Could it be built for less than a new Whizzer?
Thanks,

Any decent tandem bike is probably going to have a frame more than strong enough - they are designed for the weight of two adult riders and a much longer stretch between wheel contact patches, after all. Run a google search for "tandem bikes" - make sure the frame style will accomodate an engine.

Heck, Toys R Us has a tandem for $229.99.

Engine choice depends on lots of factors - are you in western Wyoming (mountainous terrain) or eastern Wyoming (flat as a pancake)? A GEBE system might work well, or frame mount an HT or other engine. I wouldn't reccomend friction drive.
