I was SO excited to give this Half Bike to my 14 year old son for Xmas. Sadly the bike sits un-used as it is just too hard to ride... all the neighbors have tried, I have tried and it's just too much of a risk to learn to ride. I think that the videos make it seem so easy to ride, and it is not. There is HUGE learning curve to learn to ride it without feeling like you are in danger. I wish I could give a positive review as I hate to be negative, but we are very disappointed in it... we'd gladly sell it to anyone wanting a new/barely used bike. I think that the back wheels should be wider so balancing is easier... something to make it not feel like you will faceplant the moment you get on the bike. Cool concept, just way too hard to ride... and I'm really sad about that.
