I saw the gyro-wheel at Interbike last week. Two immediate things stand out: First, while the wheel stands up on its own, it seems as soon as a child is put on the bike it will begin to tilt to one side. The gyro wheel will not keep a child from falling. Secondly, the presenters said it is designed for kids 4-8 years. Unfortunately, they’ve already missed the market. Balance bikes in Europe (and now in the US) allow children as young as 2 years to learn balance, coordination and agility…..the three hardest things about riding a bike. The pedaling is the easy part. So, the inventors of the gyro wheel seemed to have missed the world progressing around them (young children learning the skills at age 2) while they worked on their product. It is a cool concept. I just think it has a very limited audience given the success of balance trainers.
