⚙️ A Miniature Engine with Real Mechanical Movement

Inspired by the machinery that helped drive industrialisation, the ROKR Thermo Engine recreates a classic single-cylinder engine in a compact mechanical model. Its moving components demonstrate how rotational motion travels through a system of pistons, a flywheel and a pulley.

🔩 Watch the Mechanism in Motion

The model features three main modules: a cylinder, a flywheel and a pulley. As the piston moves, the flywheel rotates, while a connecting belt transfers motion to the rear pulley. An orange glowing cylinder simulates the appearance of combustion, adding a visual highlight to the mechanical action. 


🧩 A Compact, Accessible Building Project

With 58 pieces, an estimated assembly time of 1 hour and a 2/5 difficulty rating, this kit offers a shorter, approachable project for anyone interested in mechanical models. The numbered wooden components and illustrated instructions help guide the assembly process. 


🏭 Part of the ROKR Industrial City Series

Thermo Engine can operate independently or be synchronised with compatible Industrial City models. Its built-in wireless receiver supports a 2.4 GHz wireless connection, and the series also supports connection through a six-way power hub. Compatible connectors and power accessories may be sold separately. 


🎁 A Gift for Engineering & Mechanics Enthusiasts

This miniature engine is a fitting gift for people who enjoy mechanical design, industrial history and hands-on model building. Its visible moving parts make the finished piece interesting to examine as well as display.
