Turbo Exhaust Pipe for Kid’s Bike v 1.1

This is the upgraded version of the original MotoExhaust – now with a redesigned shape that gives more clearance around the rear axle to prevent rubbing or cracking. The exhaust has been switched from round to oval, keeping the same internal volume (so the sound stays just as cool), but now it tucks in even better, reducing the chance of breaking off during a fall.

The angled rear end doesn’t just look sleeker – it also improves print strength by reducing stress at the base.

🎨 You can choose between two versions:

• With a stripe (for that stylish extra touch – printable even without AMS! Your printer will pause, and you just swap the filament manually).
• Solid black version if you’re going for that classic stealth look.

Enjoy, and ride (or print) safe!

Turn your child’s bike into a roaring racer with this fun 3D printable toy exhaust! I designed this playful accessory to fit most kids’ bikes – and personally mounted it on an Early Rider Bigfoot. It attaches easily using zip ties, and I used foam tubing (miralon) to fill the gap between the frame and the exhaust mount for a snug, scratch-free fit.

The exhaust features a rotatable tip, allowing you to adjust the angle so it doesn’t get in the way of the little rider’s legs. Inside, there’s a sound chamber that amplifies the clicking noise for added fun.

It includes a clicker plate that can be 3D printed, but I’ve had the best results using one cut from a plastic binder coverusing the provided template. The clicker is secured with a 2–2.5×10 mm screw, and its position can be easily adjusted based on the bike type.

• Mounted with zip ties + foam insert (miralon) between mount and frame
• Rotatable exhaust tip for proper alignment
• Built-in sound chamber to amplify clicks
• Functional clicker – printable or cut from plastic sheet
• Requires only one small support during printing
• Durable and kid-friendly design
• Tested on Early Rider Bigfoot
• A perfect gift for young riders

Let the adventure begin – with style and an amplified (pretend) roar! 🏁

🛠️ Mounting Guide – Kid’s Bike Exhaust 

What you’ll need:

• Printed parts (main body, rotatable tip, mount, clicker – optional)
• 2 zip ties (3-4 mm wide, 10 cm long or connect two)
• Foam tubing (Miralon) or any soft spacer material
• 1x screw 2–2.5×10 mm for the clicker
• Optional: Clicker cut from a plastic binder cover using the included template

Assembly Steps:

1. Assemble the exhaust:
   Connect the main exhaust body to the rotatable tip. You can easily adjust the angle to fit the bike.
2. Attach to the frame:
   Place a foam spacer (e.g., Miralon) between the bike frame and the mount. Hold the exhaust in place and tighten it with zip ties.
3. Install the clicker:
   Choose between a printed clicker or one cut from plastic using the template. Position it so it touches the spokes while riding, and secure it with a 2–2.5×10 mm screw.
4. Test ride:
   Check the fit – the exhaust should be firm and the clicker should make a fun clicking noise when the wheel turns.
