converting a bike to a trike? Answered

anyone have info on converting a bike to a trike? My disabled son has balance issues but wants to ride with the family, however we can't afford a new adult tricycle or one of the expensive conversion kits. He's much too large for training wheels to work. I'm hoping to find a way to convert an old bike with minimal expense and no welding.

I need to convert my son's bicycle into a tricycle. He will be 10 and has Down syndrome. We have a bicycle and would like to use the wheels from his old bicycle if possible to keep cost as low as possible.

We are in South Africa ?

I still haven't found a solution, but we were talking the other day and he said he'd like a bike with a side car, so we might try to do something like that. He now would need an adult size bike as he is a large 11 year old. (5'5" and about 170 lbs)

Have you seen dirt bike "training wheels"? They're the most rediculous thing I've ever seen for learning to ride a motorcycle the right way, but they'd be beefy enough to work on your son's bicycle. And it would ba a bolt-on deal, but I'm not sure about how much they cost. I wouldn't be suprised if parents of little budding dirtbikers want to get rid of some cheap, though.

Adding a 2nd wheel to the front will cause steering difficulties, unless the 2 wheels articulate like a car's front wheels (each steering independently and in parallel). Training wheels or training wheels that are beefed up might be an easier and safer solution.

The sensible person would buy some STABILISERS. They are hardly expensive, and easy to fit so you don't have to do any hard work. Seems pretty obvious to me...

Most stabilisers are very flimsy and also not very well made, one corner too quick and they snap...

Thanks everyone! The 2nd wheel in front idea sounds interesting, then I wouldn't have to mess with the chain setup. I'll let you know if I can make it work.

If you need a hand figuring out give me a shout, depending on his balance problems you could have wheels twinned directly together in widened forks, obivously just spitballing but I'd say a trike that's closer to a bike would help with his balance issues a great deal...

Either way it wouldn't be too hard, the front one would probably be better all round it would give insane steering capabilities and alot of fun, especially if you have suspension forks, if not back suspension, one or the other, because I'd say the trike might be a bit bumpier than a bike.

Seems like you should be able to bolt on a piece of bent steel with a wheel on the edge to the existing wheel.

The 'no welding' makes it difficult, but it depends on what you are up to. You might want to think about two wheels in the front with a single driving wheel in the back. Two additional forks in the front with a steering link to the original fork could work, finding forks that have the bolt-hole for a front brake would make the steering link easier to create. Do you just need an idea or something closer to step-by-step instructions?

try one of the easy recumbent bike mods on this site, and then add a 3rd and 4th wheel in the back for stability.

Homemade pedal go cart plans would work too.
