Based on the success of last year's ZOOBMobile Fastback (which included one pull-back friction motor), the ZOOBMobile Fastback H2H features two pull-back friction motors so kids can create their own ZOOBMobiles and race them against each other. But kids can also put the motors together to make a super vehicle that goes even faster, for up to 40 feet. The Fastback H2H features 45 ZOOB pieces and 8 high-quality tires that are notched so they work like gears. Because ZOOB® pieces snap together so many different ways, kids can use their imaginations to create their own vehicles, and add on pieces from their ZOOB collections to make even more. The Fastback H2H is fully compatible with all other Infinitoy ZOOB pieces.
