I'd like to take my old tandem and make it a trike with dally tires and rims on the rear. Has anyone done it. Thanks

  • Did you want to have it remain a tandem? I don't know if any of the trike conversion kits could take the weight of two riders leaning over. The rear axle mounting bracket might snap.

1 Answer 1


There is a front-end trike conversion system called the Newton that has been used for tandems. I have no direct experience with it.

There are a number of rear-end trike conversion systems that are all similar in design: the Trykit and Longstaff. I know that Longstaff has built tandem trikes from the ground up, although I don't know if their conversion kit is suitable for tandems.

You may note that these companies are all in the UK. Triking is much more established there.

  • Nice finds! I wonder how bad it would be on a bike with the front and rear kits fitted - 4 wheels would have a terrible time keeping all the wheels on the road unless there was some significant frame flex.
