Hey, ever thought about building a bike that looks like a blocky, pixelated machine? I could design a modular frame that lets you swap parts like Minecraft blocks, and we could crank out a powertrain that’s as versatile as your creative world. What do you think?

Cool, let’s start with a simple rectangular frame made of 2x2 aluminum tubes, then we can add bolt‑together joints so you can drop in a new subframe or swap the swingarm. For the powertrain, I’d keep a lightweight inline‑4 or a V‑twin, bolt it to a central plate, then mount the gearbox and driveshaft on the left side so the right side is free for a modular rear swingarm. As we sketch, we’ll keep the bolt patterns consistent so every block line up with the same mounting points. When we hit a snag, just drop a new block in – that’s how we keep the bike evolving. Let's get the rough dimensions down first, then we’ll iterate.

Got it—1.5 m long, 0.4 m tall, tight bolt spacing. I’ll lock the central spine, then we’ll bolt the inline‑4 in the middle and keep the right side free for a swingarm slot. If anything feels off, we just swap that block. Let's nail the wireframe first, then we’ll run through the powertrain fit. Ready to sketch the first iteration?

Nice, crank the 1.5 m spine in, bolt the inline‑4 in the middle, and leave that right side open for a swingarm slot. Once we run the first layout, we’ll tweak the angles, add a subframe block, and swap in a new swingarm whenever the road calls for it. Let's get that first sketch inked and see how it rides.
