Choose from tricycles, balance, transitional or pedal bikes. These bikes come in all color and design so that you pick the one they love the most.

Go ahead, choose the bike you are looking for and have a fun ride. It all is perfect to add to your Wedding Registry or Custom Registry. The 20? Hyper Bike is ideal for boys who are looking for their next adventure. On the performance side of things, the Ultra is fairly decent, packing a 250W hub-integrated motor. This motor is capable of propelling this electric two-wheeler to a top speed of 20 miles per hour with pedal assist. Of course, you're free to go beyond this speed, given that the rest of it comes from sheer leg power.
