When installing wheels make sure to follow the instructions on how to operate the quick release and how to adjust the disc brake caliper. The steering stem must be inserted to at least the minimum insertion mark on the stem. The bolts that attach the pillow block handlebar holder are a special design so as not to turn when fastening. They must be aligned properly before tightening otherwise you can break the top cover. Tires should be inflated to the recommended pressure shown on the tire sidewall. Assembly is easier if you have some metric wrenches and some metric keys. It is best if an experienced bicycle mechanic assembles or verifies the proper assembly of the scooter.
Loosen the locking screw and then turn the inboard (closest to the wheel) adjusting screw in until the pad is about the center of the gap in the caliper. Then rotate the caliper arm so that it presses the moveable pad in and clamps the rotor between the pads. Holding the caliper arm down, tighten the mounting bolts to snug. When you release the arm, the outboard pad should not rub the rotor. Back off the inboard pad until it no longer rubs. Inspect that enough inboard pad extends into the caliper. You may need to rotate the arm slightly more for cable clamping but if you are rotating the arm too much, then the caliper can likely sit more inboard. Loosen the mounting bolts and try it again. Your final adjustment should yield a solid feeling brake in which the brake pads squarely contact the rotor. Be sure to retighten the locking screw for the inboard pad adjustor.
With the wheel centered in the fork
adjust the quick release by opening it, holding both ends, and turning one
clockwise until you close the lever about halfway and feel some resistance. Then
you can try to close the lever. The
adjustment is correct when you can fully close the lever with some effort (the
lever should leave its impression on the palm of your hand). If it is too loose
or too tight open the lever and adjust the lever or the nut and try again.
The quick-release lever should be on the
The quick release must be fully closed
to ensure safety.
If you close the lever in line with the
fork you will have something to grip while squeezing the lever. It also will
keep the lever tucked away where it can’t snag anything.
If you accidentally unscrew the quick
release until it comes apart try not to lose the little springs. They are there
to provide spring pressure to maintain some clearance between the ends of the
quick release and the axle locknuts. This will make it easier to slide the
wheel into the fork bottom. The quick release will work without them but it is
better to use them.
The springs narrow ends point inward.
When installing wheels make sure to use the special wheel retainer washers. Align the wheels and tighten the nuts securely.
The steering stem must be inserted to at least the minimum insertion mark on the stem.
The bolts that attach the pillow block handlebar holder are a special design so as not to turn when fastening. They must be aligned properly before tightening. To adjust the brakes it is easiest if you squeeze the brake shoes to the wheel with your left hand while tightening the cable wire with the cable clamp. Then you can align the brake shoes. The adjusting barrels are only for minor adjustments. The cable end keeps the cable wire from fraying. Tires should be inflated to the pressure shown on the sidewall. Assembly is easier if you have the following tools: 10mm - 13mm - 15mm open ended wrenches and a 5mm allen key. It is best if an experienced bicycle mechanic assembles or verifies the proper assembly of the scooter.
The way to attach the stand is: 1) Turn the scooter upside down; 2) Undo the left front nut that is holding on the plastic board; 3) Install the stand and tighten the nut; 4) Flip the scooter over; 5) To adjust the stand for the proper lean angle, lower the stand and apply some right foot pressure on the board while firmly gripping the handlebars until the lean of the scooter is correct. Note that the stand is only strong enough to hold the scooter up without the extra weight of the user.
