Every second Sunday, get your biking fix with the Greenway Gear Collective's bike maintenance class and group ride. Their monthly basic maintenance class starts at 10 a.m. and is a great way to learn the essentials of bike care and tune-ups. Each class is shaped by the needs of those who show up. At noon, you can join a themed group ride that will start and end at The Bike Library container on the shores of Lake Raleigh. Bring your bike or rent one of theirs. Feel free to show up for the class, the group ride or both.
