There are days where tossing your leg over the top of your commuter makes you feel like a winner. You are kitted up; your ride is dialed in; the sun is shinning and the wind is to your back. It is going to be a great day to commute by bike. Then you wake up and realize it was a dream. The reality is that your bike is skipping a gear; your tire has developed a wobble in the front after swerving into a pothole; and the wind is at your face (just like it will be when you head back the opposite direction at the end of your day). Bike commuters (myself included) love to talk about the financial freedom and liberating feeling that alternative transportation gives us. We have no qualms about climbing our ivory tower and shouting down to those pathetic car drivers, on regular occasion. The truth is bike commuting (just as all others forms) has it's ups and downs. Some days are great, while others leaving you wishing you drove.
Along the years I have tried many things to make my bike commute consistently positive. Changing gear, bikes, routes, and a host of other things. Throughout the journey there are certain rules that I have developed. Most of these are for the riders benefit, because after all we all know cars suck (unless we have a flat, or our too tired to ride to work, or it is raining).
It is not hard or more unsafe to bike commute then drive. With a few alterations to your habits and riding style you can be a safe commuter. Being prepared and investing some money go a long way in being comfortable riding on the road.
