So your kid is big enough to switch from the pram to bikes and you'd like to see if there's some champion DNA in him or her... The best thing you can do is get some riding gear and have your child throw a leg over a bike such as the 2007 MY PW50. The PW50 is Yamaha's entry-point small-displacement machine, a bike created as a nifty educational platform for introducing the youngest riders to the basics of riding.
The 2007 MY PW50 has a 2-stroke autolube 49cc engine, with a single-speed, automatic transmission, for no-hassle, clutchless, zero shifting rides, and allowing the youngsters to focus on balance and actually learning how to ride and steer.
