Santa brought this for our nine year old. He could not have been more excited when he saw this under the tree. Having charged it the full 12 hrs, the bike was ready to roll and it did not disappoint. Everything worked well and the charge held longer then we expected. The speed and maneuverability are exactly right for a nine or ten year old. Learning to use the break instead of ones feet are the biggest challenge but the breaking works well so once mastered all ok. Open space definitely makes it easier when learning. Being a good cyclist made it possible for our son to ride this right from the beginning. He has used this everyday since Xmas. Hopefully it continues to work as well months to come. So far the best present he has ever received.
