What is Zagster Bike Share?

Zagster is Portsmouth's bike share program that focuses on quick, station-to-station, transportation. The automated stations around town allow for quick trips across the city but are not intended for extended exploration.

What does PortCity Bike Tours think about Zagster Bike Share?

Bike share is a great tool for short trips and quick errands. PortCity Bike Tours is happy to be a resource to any of these new cyclists.


Need a helmet, directions, maps or accessories? We’re here for you. Think you want to take a long ride?

Considering taking the kids along?


Want to go ride some trails? We’re here for that too.


We hope that everyone who hops on a Zagster bike knows the rules of the road and follows them. We hope they have good directions and feel comfortable on their bike. We hope they wear helmets, signal their turns, and have a smile on their faces. We hope they become life-long bicyclists who ride for their health, the environment and because it’s fun!

Anything that gets more people on bikes in the city of Portsmouth is something we can get excited about.


Studies around the world have shown that more bicyclists make the roads safer for everyone, including pedestrians and drivers! We think bike share can be a great resource for Portsmouthians and a great way to reduce short-distance car trips.
