We absolutely love our Zulu Two. We purchased it for our son's 4th birthday, it's his second pedal bike, an upgrade from a 12". We were a little hesitant that it'd feel too big for him, but he was super excited about his big boy bike, and hopped on and never looked back. As avid cyclists ourselves, we are extremely impressed with the design and quality of the bike. We know we will have many years of memories pedaling on and off road together on this beautiful whip. The gang at Prevelo were very responsive to customizing our order with both road and off road wheel sets so we can cover all the terrain together. Can't wait for cyclocross season, our little guy is going to crush it. SO Much Love!
