Head Over Heels vs Flywheel Motorcycle: Physics Toys Compared
By CrunchLabs: Where kids & adults learn to Think like Engineers | Published: 2026-10-27
Category: Comparisons
Compare two CrunchLabs physics toys: Head Over Heels explores angular momentum, while Flywheel Motorcycle teaches gear ratios. Find the right fit for your young engineer.
Quick answer
Choose Head Over Heels if you want a hands-on introduction to angular momentum and gyroscopic effects; choose Flywheel Motorcycle if gear ratios and mechanical motion are the priority.
What each toy teaches
Both toys come from CrunchLabs and share the goal of helping kids and adults think like engineers, but they focus on different physics concepts. Head Over Heels is built around angular momentum, which is the same principle behind spinning tops and gyroscopes. Flywheel Motorcycle, on the other hand, centers on gear ratios, showing how gears work together to drive a spinning flywheel motorcycle.
If you are new to physics toys, the difference matters because it changes what your child will take away from the build. Angular momentum is about how spinning objects behave, while gear ratios are about how mechanical advantage changes speed and torque.
Price and value
Head Over Heels is priced at $23.39, and Flywheel Motorcycle is $24.05. Both are under the $32.95 comparison price, so each offers a saving. The small price difference is unlikely to be the deciding factor; the learning focus matters more.
Trade-offs at a glance
- Learning focus: Head Over Heels teaches angular momentum; Flywheel Motorcycle teaches gear ratios. Match the toy to the physics concept you want to explore first.
- Price difference: Head Over Heels is $0.66 cheaper than Flywheel Motorcycle, but both are under the $32.95 comparison price. Price is not the deciding factor; the learning goal is.
- Complexity: Flywheel Motorcycle involves gearing, which may be more abstract for younger kids; Head Over Heels offers a more direct visual of spinning motion. Consider your child's age and prior experience with mechanical concepts.
