Ways to cycle without buying a bike
Dublin Bikes are great. They're so easy to use. Here's a video made by Healthy Trinity: Smarter Travel, DU Film Soc & TCD SU and that shows just how easy.
Bleeper Bikes are available on campus. They are rental bikes for hire on a per ride basis that can be left at designated parking spots on campus or all over Dublin. Their 'Pay As You Go' options costs 80 cents a ride with bill pay being even more cost effective.
The maps below show where the bikes can be parked on Trinity campuses or a map of their locations all over Dublin is available here.
