Great way to get your kid ready for his/her own rides!
My 3,5 year old son loved it from his first ride on!! A little tense for the first 5 minutes, he kept on laughing and screaming joyfully during the remainder of the ride on the single trail near us.
It definitely feels safe both for him and me, preparation/installation is really easy (and foolproof!) once you've done it a couple of times.
