Universal Bike Handlebar System

Transform your bike into a fully customizable ride with the Universal Bike Handlebar System — a modular, 3D-printable mounting solution designed for endless possibilities. Whether you want to carry a bottle, haul groceries.

How It Works

The mount is available in five sizes to suit your needs. All mounts are the same size only the holes for the handlebars are different sizes. The mounts are a bit bigger but it ensures extra strength, durability, and long-term reliability for heavier loads and it uses the same accessories because they are the same size. The mounting system has two sections — a top and a bottom — with the bottom slightly extended to reduce stress on your accessories.

Accessories slide in using a simple fitment system. Once in place, a locking plate  and bolts ensures your accessory stays secure,  even on rough terrain. Installing the plate is easy: mount your accessory, remove the two front screws, place the plate over the same holes, and screw it back in.

Included Accessories:

1. Bottle Holder / Basket

Dual-purpose design: works as a standard bottle holder(fits 74mm bottle) or a compact cargo basket.

Thread on top allows for a lid or cover to lock your items in place.

2 printable versions:

Honeycomb pattern for lightweight strength.

Solid wall design to keep even the smallest items from slipping through.

And both with or without threads.

2. Small Hook

Perfect for carrying bags, helmets, grocery totes, or anything that can hang securely.

Simple, practical, and quick to swap with other mounts.

3. Universal Vertical Mount

Vertical loop mount for ultimate flexibility.

Works with clip-on mounts, straps, or zip ties — great for custom or experimental setups.

4. Horizontal Universal Mount("Top_universal_mount")

Uses the two rear mounting holes of the main system or can be used instead of the locking plate("Accessories lock").

Similar to the vertical mount but positioned horizontally for different attachment possibilities.

Printing Tips

For best results when printing this system:

Layer Height: 0.20 mm.

Supports: Not required — all parts are designed to be printed without them.

Perimeters & Infill: Use more perimeters for added strength and 15–30 % infill.

Only use support brims mostly for the 

Material: Choose durable, heat-resistant materials such as PETG or, even better, ASA. These handle outdoor conditions and direct sunlight much better than standard PLA.

All of the parts have tolerances, so they should easily slide in and the same goes with the threads.

Print in orientation as provided.



 

How to mount:
 

You will need 4x M5x70 bolts, 4x M5 nuts and 8x M5 washers.

1. Take both parts top and bottom:

2. Put them around your bike handlebars. They go around the handlebars using the middle hole as a mount.




3. First screw in two back bolts(Use M5x70 bolts, shorter like M5x60 can manage too, but I recommend using longer ones). Secure them with 2 M5 nuts, don't tighten them yet.
 

4. Slide in your chosen accessory.
 

5.Secure it with the locking plate("Accessories_lock") and use the same bolts and nuts again with the same washers as in step 3. After that tighten everything and make sure everything is snug.



If you want to change your accessories undo the front two bolts and remove the locking plate.

Change your accessory and repeat step 4.



Customize you layout however you want and however you need.
