Bought this for a friend who is a BIG car guy. He got started and could not put it down. Took him 2 weeks. Said it was a quality product, would definitely buy again!

I bought this as a gift and it was a big hit. It’s super cool and they loved it. The build is a bit challenging, but it’s worth it.

My 8 year old put this together in one day he was so proud of himself. He's had other kits like this, but this one he actually finished and got to work.

Motorized L4 Engine
See it. Build it. Understand it.
Meet the BioBricks Inline-4 Engine — the engine that powers more cars on the road than any other design, now electrically driven and built brick by brick. Engineered with 1,787+ precision pieces, this is the most mechanically transparent build in the lineup — every cam, chain, piston, and gear visible in real time.
Every part. Fully visible.
Whether you're an engineering student, a car enthusiast, or just someone who's always wondered what's happening under the hood, this build was made for you.
Why you'll love it:
🔍 Open cross-section design — see every internal component working in real time, no guessing, no mystery
⚙️ All four pistons move in perfect firing sequence — cams rotating, timing chains looping, everything visible and in motion
🎓 The most educational build in the lineup — pure mechanical motion laid completely bare
📖 Full-color English instruction manual — guided from first brick to last, no guesswork
🔋 Battery-powered, ready to build — motor and battery box included, just add batteries
