I'm a big ol' noob, so this here is my first attempt at making my well loved but awfully cheap mountain bike a "commuter" bike.
I've changed the tires out from nobbies to slicks (flak jackets), added fenders, a handlebar mirror, a few lights, a rack, air pump and bell so far to make it more road friendly. I already had a computer, water bottle, locks and saddle bag, which would've been necessary additions had I not already added them.
Also note the fancy "one less car" sticker, which I can
now proudly display.
