Just when you think you've mastered the world of children's bikes, the Quadrabyke comes along to shake things up. As other bikes, this has a frame, handle bars and pedals, but the Quadrabyke comes with four sturdy tires. Parents can opt to set the bike up on two-, four- or three-wheels so that it can evolve from a four-wheeler to a tricycle to a bicycle as your child masters each stage of riding.

The assembly was a little challenging and time-consuming, but once we understood the process, the bike was up and running and a big hit with test group. Unlike other tricycles our 3-year old tester has used, the Quadrabyke gave him the ability to pedal much more smoothly and, much to his older brother's chagrin, he can now confidently keep pace. The bike has been well-constructed, well-priced, and well received.
