Introduction: Skate-buggy / Soapbox Derby in Rural China

Recently I was traveling through rural china. in the mountainous areas in southwest Sichuan province, near Xichang, i was excited to see on several occasions young kids zooming down steep hills on their simple home-made rolling chassis, deftly avoiding the ubiquitous busses and dumptrucks. their buggies are stripped-down soapbox-derby style, or maybe you'd call it a skateboard or skate-car. I don't know how local this hobby is, I did not see it in Yunnan provice but I also saw less kids playing in traffic there too. I think this must be a fairly new hobby, as there were no paved roads in these areas until about 5 years ago and these buggies will only work on a paved road with the wheels they had. All the kids in the videos are Yi people, a minority culture that lives in and around Xichang.




Step 1: How to Do It

unfortunately i only got a good photo of one of the buggies, both the kids in the first video use the design shown in the first photo below. the kids in the second video have a somewhat more complex design, the best photo i got of it is in the 2nd photo below.

1st design shown below: the wood bits are pretty obvious, just sticks and scrap wood. the three wheels are large ball bearing races from some unknown deceased vehicle or machinery. they just whittled down the sticks and jammed the bearings onto them, then nailed the wood together.

operation: to steer, you just lean left or right a bit, and twist the front wheel a bit left or right using the hand grip.

the 2nd design below is a bit narrower and more like a skateboard than the first, the two-wheeled rear-end is straightforward as shown in the photo. the front end has a more complex setup with a steering column - there is a vertical stick which has a perpendicular handle at one end for steering, and the front wheel is mounted at the bottom end of the steering column on another perpendicular stick. note: i'm not sure the more complex steering system here is actually an improvement. the reason i didn't get a good photo is that the kids were afraid i was going to steal their buggy and wouldn't let me near it!

Step 2: Be an Emissary

also when traveling in developing areas it is important to spread goodwill. i gave instructables stickers to all the kids with homemade deathmobiles. they thought the stickers were totally awesome. i did not tell them what to do with the sticker, about a quarter of them immediately stuck it to their heads, as shown below.
