Frame Build
Carefully remove and discard the protective foam and shipping materials from the frame using scissors. Keep the cardboard box handy as a protective work mat.
2. Remove and discard the supplied brake levers by loosening the connector by hand and removing the end of the cable from the lever. We will replace these with an alternative “eBrake lever” in a later step. Do not remove the brake cables.
3. Remove and discard the supplied kickplate (wood) using a Phillips screwdriver. Put the screws back in their holes for later – don’t lose them! Note: You will attach an alternative kickplate in a later step.
Find the parts to build the larger 26-inch wheel (rim) with hub motor, 26-inch tire, and 26-inch tube.
2. Shape the tire.
3. Unroll the tube. Remove the valve stem cap from the valve stem and add just enough air using the pump to begin forming a squishy donut shape. Hint: Keep track of the valve stem cap, you’ll need it later!
4. Carefully fit the tube inside the shaped tire.
5. Important Step: Tires/ wheels are often designed to rotate in a certain direction. Check the tire to see which way it rotates. The wiring of the wheel hub motor will be on the right side of the scooter, so the wheel should rotate clockwise when you are looking at it from the view of the wheel motor wiring.
6. Insert the valve stem through the hole in the rim. To make things easier in the next few steps, replace the valve stem cap (that you didn’t lose in step 3!).
7. Slowly begin to work the tire into the inside of the rim. Be careful not to pinch the tube inside, or you might get a flat tire later. See if you can do this with only your hands. If the tire is stubborn, you can use a rounded plastic tire lever to gently pry it. Never use a sharp metal tool here (such as a screwdriver or knife), as it could damage the tire, tube, or rim (wheel).
8. Before you add the rest of the air, gently push the valve stem out further so the pump can reach it. Add air to the recommended pressure level shown on the side wall of the tire. Don’t forget to replace the cap!
Find the smaller 20-inch rear wheel (rim), 20-inch tire, and 20-inch tube.
2. Shape the tire.
3. Unroll the tube. Remove the valve stem cap from the valve stem, then add just enough air with the pump to begin forming a squishy donut shape. Hint: Keep track of the valve stem cap, you’ll need it later!
4. Carefully fit the tube inside the shaped tire.
5. Align the valve stem in the rim. To make things easier in the next few steps, replace the valve stem cap (that you didn’t lose in step 3!).

Work with a partner to keep the frame steady while you assemble these parts.
Carefully disconnect the rear brake caliper so that the tire can easily fit into place. Do this by pulling the cable joint toward you while pushing the caliper toward the wheel. Then, remove the cable by lifting it up and out of the way. Note: You may need to adjust the brake settings to accommodate the wheel. We will do this in a later step. Do not reconnect the brake caliper yet.
2. Check the rotation of the 20-inch (smaller) wheel by looking for an arrow on the sidewall of the tire. The wheel should rotate toward the front of the scooter.
3. Slide the hub of the wheel assembly all the way into the frame slots and tighten the nuts using the adjustable wrench. Hint: Make these snug, but be sure not to overtighten them.

2. Check the wheel's rotation by looking for the wire coming out of the hub motor. This should be on the right side of the scooter (when viewed from the rider's perspective). The wire also needs to point up, and the “washer stud” needs to point down. This may require removing and reorienting the nut-and-washer stud on the wheel before attaching it to the fork dropouts (the slots where the wheel bolts to the frame).
3. Slide the wheel assembly hub all the way into the frame slots, then tighten the nuts with the adjustable wrench. Hint: Make these snug, but don't overtighten them.

Using the provided bolt, mount the kickstand using the 8mm hex wrench so that the leg is toward the left (as the scooter faces forward).
2. Turn the scooter upright and try to balance it on the kickstand. You may need to adjust the length of the kickstand. Use a Phillips screwdriver to set the correct leg length.

Insert the handlebars stem into the steering tube. Use the marks on the stem as a guide for depth and orientation.
2. Use the 6mm hex wrench to tighten the stem from the top. Hint: Make snug, but don't overtighten.

Carefully insert the handlebars through the handlebar stem coupling. You may need to gently twist and turn the handlebars to get them into position. Use the marks on the handlebars as a guide for final placement.
2. Use the 6mm hex wrench to tighten the coupling that holds the handlebar. Hint: Make snug, but don't overtighten.
Attach the eBrake levers to the handlebars using the 4mm allen wrench. Make sure the levers are positioned so the bolt head faces up. You will attach the cable and make adjustments in the next step.

After completing these steps, you are ready to begin testing your circuitry. The next activity will cover those steps.
