sheesh, you guys, aerospokes are so pre2005.

Now full disks front and rear are the way to go for aero speed on the street.

fixed recumbant and stay on flat ground?

why would you wanna go faster? ;)

i have a pet hedgehog named snarf :)

tie it to a car

Tight clothes and yellow shoes. Remember the yellow shoes, they're important.
