BajaBoard G4 / G4X DIY Chassis | All-Terrain Electric Skateboard Build Kit

The BajaBoard platform. Your electronics. Your rules.
G4 (2WD) or G4X (4WD) — same battle-tested chassis, zero compromises on what goes inside.

You Know What You Want. We Built the Foundation.

You don't belong to one sport. You belong to the feeling — and some of us need to build that feeling from the ground up. The BajaBoard G4 / G4X DIY Chassis is for the rider who already knows what motors they want, what controller they trust, and exactly how they want their board to behave. We built the hard part. The suspension geometry, the belt drivetrain, the deck, the battery box, the 10-inch wheels — all engineered to the same standard as the full BajaBoard lineup. You bring the electronics. You bring the vision. The result is entirely yours.

This isn't a compromise kit for riders who can't afford the full board. It's a platform for builders who want more control than any off-the-shelf setup can give them. Choose 2WD with the G4 chassis for a lighter, longer-range build. Choose 4WD with the G4X for maximum traction and the kind of all-terrain grip that makes rough ground feel like home. Either way, you're starting with a chassis that has been stress-tested across every surface BajaBoard riders have thrown at it — and that's a long list.

The suspension is already installed. The belt drive is already configured. The motor mounting plates are ready. All that's left is your imagination — and whatever electronics you've been waiting to put to work.

Why You'll Love It

• Battle-Tested BajaBoard DNA: This is the same chassis architecture that powers the G4 and G4X production boards — independent suspension, shock absorbers, belt drivetrain — engineered for terrain that would destroy anything lesser.
• 2WD or 4WD — Your Call: The G4 chassis gives you a nimble, efficient two-wheel-drive platform. The G4X gives you four-wheel grip and the confidence to point it at anything. Pick the one that matches how you ride.
• Full Suspension Pre-Installed: Front and rear suspension structures with shock absorbers come ready to go. Choose your coil colour — green, red, blue, or black — and the chassis arrives dialled in.
• Open Electronics Bay: 430mm × 90mm × 80mm of internal battery space, motor mounting plates ready for your chosen motors, and a clean wiring environment. No hacking required — just build.
• 10-Inch All-Terrain Wheels Included: The same oversized wheels that give BajaBoard its signature ground clearance and off-road capability. Ready to roll the moment your build is complete.
• Total Build Ownership: Your motor. Your controller. Your battery. Your tune. No manufacturer lock-in, no firmware restrictions. This board performs exactly the way you set it up.

Imagine It In Your Element

Scene 1 — The Build Bench, 11pm: The chassis is on the workbench, suspension already installed, coils in black because that's how you wanted it. Your motors are bolted to the mounting plates. The controller is wired in. The battery — a custom 12S pack you built yourself — sits snug in the battery box with 3mm to spare. You close the deck, flip the board over, and look at what you've made. It doesn't look like anything else on the trail. It isn't. Tomorrow you find out what it can do.

Scene 2 — First Ride, Gravel Fire Road: The board launches harder than you expected — because you tuned it that way. The suspension absorbs the first rough patch before you even register it. You push the throttle further. The 10-inch wheels grip and roll over a root that would have stopped a smaller board cold. You're grinning inside your helmet. This is the board you designed, built, and dialled in yourself. Every part of this feeling is yours.

Build Something That's Entirely Yours.

Most boards tell you how to ride. This one asks what you're capable of building. The BajaBoard G4 / G4X DIY Chassis is the starting point for a machine that no one else will have — because no one else made the same choices you did. Every rush. Every realm. Join the collective. Build your board.
