Scene tag
Connect any number of bikes together. Two types of coupling bars shown. One uses a coil spring. The other uses a ball and socket.

Uses My first bike with suspension by BrAzAs. Used without permission. Scene will be deleted upon BrAzAs request.

Rev A: Universal joint replaced with ball and socket joint to allow twist (along with swivel and tilt).

Rev B: Added coil spring coupling.

Rev C: Grouped bike with coupling in order to make it easier to add bikes. Added a few more bikes.

It needs to be able to twist too <_<

Yes, now that you mention it, I can see that it is true. A number of years ago, I constructed a coupling as originally described and it worked out fine. Now I wonder why. Maybe the joints were loose enough to accommodate any required twist.

Holy cow... It's beginning to look like a 90-car freight train! LOL

So, I wonder if there is a theoretical max number of bikes/riders in this scheme. I'm sure that it becomes impractical over a certain number, but I wonder if there is a point where the frictional losses and other energy losses become greater than the energy output of the riders? (Maybe no one has ever bothered to calculate it! :lol: )

I suspect there is no theoretical max number of bikes with riders since the additional friction due to the weight of the coupling bar would probably be more than offset by the reduction in wind resistance. Starting and stopping would be another story. There may also be a problem with freeloaders.
