Time for Machine - Chrome Rider - Mechanical 3D Puzzle for Adults, Mechanical Model Kit for Self Assembly, Bike Model

The instructions could be a bit more clear (some drwings are confusing). At least 7 pieces left over (spare parts maybe?). This model has an inertial "engine", not a spring type, for self propulsion. The mecanism works backwards but not forward (maybe just an user error).All in all, quite a nice experience and a beautiful model.

This was a fun project. It was challenging and wasn't a long project. This is only the second Time For Machine project I've done and find there instructions a little lacking. It help to find a video if available. Take your time because if you bend the metal the wrong way and try to bend it back, you take a chance of breaking the metal.

Looks good, everything meshes and spins correctly and feels great when held. Reasonable amount of difficulty for the price. But, in the end, it won’t roll as pictured in the YouTube videos. The rear wheel and flywheel seem generate the necessary torque but the pivoting front wheel means it won’t go. Maybe If you jam something in the front to prevent it turning

Package came damaged with loose and missing items. Obviously this was a previous return that was sent to me. Very disappointing.

There are tiny sticks that need to be removed. Those shouldn’t have been part of the metal sheet, they break while removing and now I can’t finish building.

And fun to build
