Hello and welcome to my first instructable! This is a brief instructable that I created to help others bike quickly. You don't need a fancy bike, spandex (ew), or anything besides your normal every day clothes to bike quickly!
Step 1: Preparing your bike...
Some people may find biking in jeans difficult, and if you seriously can't, then don't. I just wear a regular t-shirt with shorts. You don't even need to bike every day!
Alwayts make sure to get a tune-up every once in a while. Lie your bike down on its side. Spin both wheels, and make sure there is no scraping sound. This means your brakes are too tight, which may slow you down significantly. Also oil your bike occasionally, you don't need to do it that much. DO NOT USE WD-40 ON YOUR BIKE CHAIN!!! THAT WILL DAMAGE IT!!! Just buy a small bottle of bike oil from a local shop.
Ok, now that's over with.
