Waltham: Jumpstart your Bicycling Meetup

Are you ready to get on your bike and ride?Time to dust it off and work on what you need to know to use it for fun, fitness and transportation. We're having an easy bike ride to bicycle history sites with an acclaimed author, and an indoor/outdoor class on basic bicycle adjustment for smooth running and comfort, on-road repairs (flat tire repair, replacing a dropped chain...), using the gears, safe riding on the road and path.
