Does your employer provide a safe place to secure your bike, and showers to wash off the workout to work? These amenities will not only improve your bike-commuting experience, they'll also encourage coworkers to bike commute, as well. Does your boss know the IRS allows them to make tax-free $20/month incentives for biking to work? Give a nudge to employers that haven't gotten the memo about the benefits of bike commuting, and ask them to create a biker-friendly workplace. The same goes for apartment buildings that lack good bike storage, and even your favorite stores or clubs. If you don't speak up, business owners won't feel the need to make more room for bikes.
