Rated 3.7 out of 5 by 3 reviewers.
Rated 1 out of 5 by Disappointing Our 7 year old son has been disappointed with this bike. First the handlebars came off two days after it was assembled by Dicks. Dicks fixed it and luckily he wasn't hurt. Then after 5 days of riding around the neighborhood the pedal broke. September 12, 2016
Rated 5 out of 5 by Great Bike for a Fantastic Price Great options for a child needing to take the first step into gear shifting and hand brakes. Bike is well made, we took advantage of the 'free in-store bike assembly' option after having the bike shipped to us. The bike tech in Newark DE was extremely attentive and had our bike put together the same day we dropped it off, which really impressed. Only way to improve my experience would have been an intuitive option at check-out to have the bike shipped to store and assembled without having to drop it off. August 24, 2016
