We love our Alpha 2. It was purchased for our daughters 4th birthday. She is an experience balance bike rider, and was able to ride this bike on her own the day after opening the box. She loves it and rides every day. As a bike rider, I love the kid centered design and the quality components. From the easy pull hand brakes (no coaster brake), the low stand over hieght, comfortable seat position, the kid-sized crank, proper wheels tires and hubs, all make huge difference. There is not a single cheap piece of plastic on this bike. I bought this after watching her ride a hand-me-down huffy with training wheels - she fits on the bike but cant touch the ground, gets mixed up by the coaster brake, and relies heavily on the training wheels which means she cant turn without tipping over. This was a game chagner and my 4 yr old was zooming around the neighborhood right out of the box! Even better, she is super excited to ride her bike every day.
