Shift AUTOMAGICally Is your little Rider already wishing they could go a bit faster? Children between four and six who do lots of pedaling will love the woom GO 3 AUTOMAGIC and its automatic 2-speed shifting! This special bike has two gears, but your child doesn't have to worry about switching between them. It not only allows them to ride faster in top gear, but the lower gear also makes getting started a cinch. The internally geared hub automatically switches gears at roughly 7 mph without any manual shifting necessary... it's automagic!
