Safety Tips

Your safety is our top concern. Follow these safe riding tips to make the most of your Boulder B-cycle experience.

Follow the law
If you’re new to Boulder, take a moment to read up on our bike laws below.
Obey all signs and signals
When riding in the street, all signs apply to you, including stop signs and traffic lights. Stop when you’re supposed to, and always yield to pedestrians.
Keep off sidewalks & pedestrian malls
Don’t be a nuisance to pedestrians by riding where you’re not supposed to. Boulder has hundreds of miles of multi-use bike paths and lanes, so you should have no problem sticking to those. You can find maps of bike routes on the City of Boulder’s website, or on the printed maps at each of our stations.
Ride predictably & use hand signals
Make your intentions clear to all other road and path users. Ride in a straight line, signal turns, use audible signals if passing pedestrians and other bikes, and check behind you well before turning or changing lanes. Make eye contact with drivers.
Wear a helmet—not the law, but a good idea
The City of Boulder does not require riders to wear bike helmets, nor does Boulder B-cycle’s user agreement. However, protecting your noodle is always a good idea. You can bring your own helmet along or check out one of the helmet rental spots featured in the following section.

Helmet Rental

While bike helmets are not required by law in Boulder, it’s still a good idea to wear one. If you’re looking to rent a helmet while you’re here, these bike shops provide helmet rental.
