Kid-sized coasting trike made from bike parts, scrap, and golf bag cart wheels. Not tested for adult or husky-kid use, or high speeds. Ride at your own risk!

Step 1: Layout of Parts

After posting a request on the local Freecycle group (www.freecycle.org) for any old bike parts or used bikes, I found myself with a huge pile of bikes of different sizes and in various conditions, most of which had been left outside so they had a good bit of rust on them. For a couple of months I stared at the bikes, took most of them apart, and started to come up with ideas of some goofy bikes to try to mash together. This would be my first attempt at a bike project, so I had a lot to learn (and still do).

In addition to the rusty bikes, I had a cheap kiddie bike from Goodwill ($4) and an old golf bag cart that was also bought cheap at Goodwill. It was very sturdy and had lots of metal parts that could be used on various projects. I used the frame of the kiddie bike, a fork from another bike, handlebars from yet another bike, and the wheels and handle of the cart (the handle was used for the seat post). The front rim was actually a stray that was bought at a sell-off from a nearby Kmart store that was closing down (boy did they have lots of goodies they were selling off that I wished I could have bought! Including a bin full of brand new shopping cart wheels!). I already had a tube and tire that were the right size for that rim.

Once I had the crazy trike idea in my head, I laid out some of the parts to see what work I would need to do next. First I removed the fork and handlebars from the kiddie bike and replaced them with a bigger fork and different handlebars. If you are new to working on bikes and either find yourself with a pile of bikes of your own or wanting to accumulate a pile of bikes, just keep in mind that not all parts will be interchangeable, and if you don't have the tools and know-how to make everything fit the way you want it to, you may need to be careful of the sizes and styles of bikes you get. This may limit the kinds of projects you will be able to complete.
Interesting build, looks like fun but i would not risk trying to slide it into any corners, the center of gravity looks a bit on the high side, make sure all riders wear helmets. &nbsp;At least you put brakes on it.<br> <br> If you are going to build a drift trike the most important thing is to get the center of gravity down as low as possible, but not that low that bumps in the road become hazards, between about 2-6&quot; of the ground should be safe eough, other than that make the rear axle wide, &nbsp;build you drift trike long, low and wide as short&nbsp;narrow&nbsp;trikes have a&nbsp;tenancy&nbsp;to flip over and you will only do that so many times before something bad happens and you get hurt (trust&nbsp;me on this, i have the injuries that 20 years on require daily meds)<br> <br> the only other tip you need is buy go kart wheels, other wheel will do but they don't last long enough or are not designed to cope with the speed that a drift trike is&nbsp;capable&nbsp;of,&nbsp;<br> <br> The only other real good tip i have is to check the many drift trike groups and crews on Facebook, you will see lots of&nbsp;different&nbsp;trike builds there from&nbsp;ultra&nbsp;simple to engineering masterpieces, you will also find&nbsp;allot&nbsp;of pics of short, narrow trikes with high center of gravity flipping out and throwing the riders.<br> <br> Good luck with your build.
Has a kid tried this yet?
Yep- a 75 pound kid on the driveway (until the seat came loose). The asphalt around where we live is pretty crappy, so we still need to find a big enough sloped area that isn't too bumpy to test it on. The structure seems strong enough so far, but the seat post could use a weld or something to keep it set where it needs to be.
