Query: Very Disappointed!

We received this overnight, and we are always pleased with Amazon's service. The bike however was a total diappointment. It was also defective/broken. The back wheel was totally bent and would not allow the bike to move forward. Good thing Amazon has an awesome return policy for Prime Members!I should have listened to the reviews that said:1) The bike is very heavy and hard to push along. Its a good bike for an older 5 or 6 year old, but not a great idea for a 4 year old. Our son is big and rides well, and its STILL very heavy and hard to maneuver.2) Its not worth the extra $50 or so that I spent on it. It looks cool, but is not of very high quality.Also, we received it damaged.Bummer. Best to go to a store and find a bike that fits your youngster!
