This DIY project is driven not just by the typical maker's passion for building and tinkering, but by the idea of creating a DIY scooter with extra-large wheels that glide smoothly over uneven terrain and even help you conquer small curbs that are impossible for conventional models with smaller wheels.

So, how do you build a scooter, and where do you start? The creative spark comes from looking at your kids' old, unused little bicycle—they're all grown up now—which has two nice 12-inch wheels. Obviously, since you're using the wheels, it makes sense to also use the front end, meaning the fork with its stem and head tube. You also take the cables and housings, grips, brake levers, calipers, pads, and other details. But to shape the scooter, you also need to build a horizontal load-bearing frame, to which you attach the rear wheel fork on one side and the support post for the front end on the other. For this, you go to the blacksmith to salvage some scrap pieces.
What You Need to Build a DIY Scooter
- A tubular piece 100×20 mm
- Cylindrical tubes
- Flat bar 30×10 mm
- Some 5 mm thick angle segments
- A non-slip aluminum tread plate
The pieces must be properly cut and welded to join them securely, except at one critical point to keep the ability to fold the DIY scooter and easily stow it in your car trunk. This involves creating a sturdy hinge at the base of the steering column, with a quick-release and safety lock system. You can also telescope and fold the handlebars, just like on any bicycle.
Building a Scooter with Recycling and Safety in Mind
Time required: 1 day
Step 1: Weld the Brackets to the Main Frame Rail
Start by cutting your main frame rail from the 100×20 mm tubular piece. Weld the brackets that will hold the front steering column hinge and the rear wheel fork. For a sturdy foundation, consider upgrading your home improvement workshop with quality tools and materials.
Step 2: Prepare and Attach the Front Steering Column
Take the cylindrical tubes and the flat bar to fabricate the steering column. Use the angle segments to reinforce the hinge point. This is where the folding mechanism will live, so precision is key. A good lighting setup in your workspace makes detailed work easier.
Step 3: Build the Rear Wheel Fork
Using more of the flat bar and angle segments, create a strong rear fork that will hold the 12-inch wheel from the old bicycle. Weld it securely to the main frame rail. Keep your garden supplies organized while you work on this project.
Step 4: Install the Deck and Non-Slip Surface
Cut the aluminum tread plate to size and weld or bolt it to the top of the main frame rail. This is your standing platform. A non-slip surface is crucial for safety. Pair your new scooter with a comfortable outdoor patio furniture set for relaxing after your ride.
Step 5: Assemble the Braking System
Route the cables from the brake lever on the handlebars down to the caliper on the rear wheel. Use the original bicycle parts for authenticity and reliability. Test the brake action thoroughly. For evening rides, check out our outdoor lighting collection to light your path.
Step 6: Final Adjustments and Safety Check
Tighten all bolts, ensure the folding hinge locks securely, and check that the wheels spin freely. Inflate the tires to the correct pressure. Your DIY scooter is now ready for its first ride. Store it neatly in your garage or sheds when not in use.
Frequently Asked Questions
Can I use any old bicycle wheels for this project?
Yes, 12-inch wheels from a child's bike are ideal. They provide good stability and roll over obstacles easily. Just make sure the tires are in decent condition and hold air.
Is welding experience necessary?
Yes, this project requires basic welding skills to join the metal frame parts securely. If you're new to welding, consider taking a short course or asking a friend with experience to help. Always wear proper safety gear.
How do I make the scooter foldable?
The folding mechanism is built into the steering column hinge. Use a quick-release lever and a safety lock pin so the scooter stays rigid while riding but folds flat for transport. This design makes it easy to fit in a car trunk or store in a storage bench.
What safety features should I add?
Besides a reliable brake, add reflectors or a small LED light for visibility. Always wear a helmet and knee pads when riding. For extra comfort, consider a soft rug for your workshop floor while building.
Can I customize the scooter's appearance?
Absolutely! Paint the frame in your favorite color, add grip tape to the deck, or install a small basket. Personalizing your DIY scooter makes it uniquely yours. Decorate your workspace with wall decor to inspire your next project.
