WAYS TO USE BIKES AND TRANSIT TOGETHER.

Suburban to City Commute: Bike commute downhill into town, take the train or bus home. Or, keep a bike parked downtown so that you have quick access to more places to eat or shop at lunch time. Avoid rainy weather, bringing your bike with you on transit rather than getting wet. Bike from home to the bus or train, and then continue on with your commute. When you get to your destination, you will have your bike to help you continue on with your trip.

Suburban to Suburban Commute: Bicycle to the train. Take the train or bus as close as you can to your workplace. Then bicycle to your destination.

Cross rivers and lakes: Many bridges do not have bicycle or pedestrian access. Bringing your bike onboard a bus, train, or ferry can be the answer.

Access National Parks: Many National Parks now have buses with bike racks. Having a bike allows you to cover more ground than walking. Acadia National Park and the Grand Canyon are good examples.

Carpooling: Ride with a friend to their worksite and then bicycle the rest of the way to work.

Use two bikes: If you don't want to, or can't bring your bike on transit, then keep an inexpensive bike parked at each end of your transit ride.

Use a folding bike: Folding bikes are small and can be carried onto almost all vehicles. This is especially helpful on airplanes and on Amtrak, which limits bicycle access on many trains (but has great access on others, such as the Vermonter and route along the Pacific Ocean).

Traveling: For someone visiting a city on business, a bike is a great way to get to a nearby park trail.
