We did a lot of research before purchasing a balance bike for our grandson. Actually, WeeBikeShop had some of the best explanations and education on the web. We settled on the Yedoo TooToo because of 1) the pneumatic tires, 2) the brake and 3) the geometry. He took to it easily, biking along no time at the pace of a fast-walking adult. The second summer he mastered coasting and braking on hills. Now, his sister is happy to take over the TooToo - which still looks and performs like new. WeeBikeShop quickly helped us out with our only problem- replacing a seat post clamp we accidentally over-tightened. Great bike & service!
