The world opens up when you get your first bike. Diamondback's Insight 20 expands a kid’s experience even more by adding multiple gears to the mix. Based around a durable and lightweight alloy frame, their smallest performance hybrid bike is a great introduction to longer rides and new adventures. The 20-inch wheels are still manageable by smaller riders, and a Shimano twist-grip shifts easily through seven speeds. If your young rider is ready to explore what’s beyond the end of the street, the Insight 20 is a perfect choice.
