Ed,
I just wanted to share our success with Glide Bikes with you. We received the bikes for our twin girls (five years, two months old) on Thursday.  I immediately assembled them, which was very easy, and they started practicing after dinner on Thursday.  After 45 minutes they were making great progress.  We repeated the practice on Friday night, and they were gliding anywhere between five and eight yards.  On Saturday morning, I took off the training wheels on their regular bikes. They were riding their “big girl’s” bikes in less than an hour.
By the way, the Glide Bikes are quite the show in the neighborhood.  Looks like product and brand awareness can still increase for these great bikes.
