6 Attach the steering assembly
Line up the eye of the eye bolts in the neck [c] with the eye of the eye bolts in the steering upright [e].

Thread a 1/2" carriage/coach bolt through the eyes of the eye bolts to act as a steering pin.
Make sure that the steering assembly can turn freely and then tighten two nuts together at the end of the carriage/coach bolt to form 'lock nuts'. This will ensure that the steering pin does not fall out or vibrate loose with constant movement.

7 Secure the neck
Fasten an angle bracket to the neck [c] and the deck [d] with screws.

This is purely to increase strength.

8 Assemble the rear wheel
Assemble the rear wheel in the same way as for the front wheels in step 3.

Make sure that there is a washer each side of the wheel and also that the wheel can rotate freely, before applying 'lock nuts' at the end of the bolt.

9 Add the brakes
Screw a T-hinge to the rear of the deck [d].
This is the brake.

Finished!

Some scooter safety stuff

ALWAYS use a helmet, knee pads, and elbow pads.
This is a small investment and can instantly eliminate almost two-thirds of possible scooter accidents.

Children under eight should always be supervised when using scooters.
Almost a third of all scooter-related injuries and accidents involve children under the age of eight. As everyone knows, scooters are capable of traveling very quickly, and children that age do not always have the judgment or coordination to handle these high speeds.

Use scooters in a safe places.
Cars and scooters don't mix, especially for younger riders. Smooth, paved surfaces are best - avoid bumpy, uneven, wet or rocky surfaces. School yards, parks, paved trails are examples of safe places to "scoot"!

Do not ride a scooter at night.
