Learning to balance before learning to pedal also makes sense for adults who want to practice for the first time. That’s why SF Bicycle Coalition instructors use the same tactics in Freedom from Training Wheels as in their Adult Learn to Ride Classes. The priority is learning to balance, then pedaling and turning come next. For over 40 years, the SF Bicycle Coalition has been transforming San Francisco streets and neighborhoods into more livable and safe places by promoting the bicycle for everyday transportation.
