Ive been toying with this old mountain bike for a while now. The wooden rack that I built can now hold the weight an adult, so it does a good job of carrying my junk... and it cost very very little to make. With the semi-slick tires, it has become my commuter, since I only have 0.7 miles to work
and it allows me to be 95% car-free! Coming soon, wooden (lockable) removable panniers, wooden fenders, & homemade trailer.
