Ace gets her mountain bike ready for the big bike race, but during the race Ace's bike chain comes off the sprocket, and a tire goes flat--luckily she has her tools with her to fix the problem so she can finish the race.
Ace builds her own skateboard, but it takes a lot of practice (and some falls) to learn to skate well--and then she builds a ramp and takes it to the park to skate with her new skateboarding friends.
Ace has built her own go-kart, but when she is ready for a test run it will not start, and she has to figure out what part is missing--and then in the middle of the race something else goes wrong.
