Recently I realized that my street luge instructables are pretty vague, so here I will show many pictures. I will also explain the function of anything on the luge, and point out my newest modifications. I will include a few tricks I picked up, and will go in depth about the construction of a street luge.
As for the extreme contest, street luge is very extreme. Rolling down a busy road at nearly 30 mph? Dangerous, yet fun. While riding a street luge, you are just one pebble away from falling off and crashing. Street luge is so extreme that I was ordered to stop doing it by my parents. If dangerous+fun=extreme, then street luge=extreme!
Step 1: Construction of the Luge
The construction of a luge is pretty simple. One main 2x4. Skateboard trucks go on the bottom, one in the far back, one abou 1/3 of the way down from the front. Footpegs are added near the front trucks. A seat is added where you can comfortable sit, and a backrest is right behind that. The backrest is held up by a couple small pieces of 2x4. Handholds are optional, as you can just hold onto the seat.
