How to Assemble a Big Wheel
Big Wheels can provide children with endless hours of enjoyment, but assembling them can be a bit tricky. Indeed, the unique design of these vehicles can create problems in construction, as elements of its design call for comlex assembly instructions 1. Nevertheless, Big Wheels come with every part necessary for assembly, and construction only requires a hammer and a screwdriver. Assembly is possible by almost anyone, and can prove a very satisfying procedure.
Remove the small yellow caps from the axle (long, thin rod) and secure one capnut onto an end of the axle. Place a capnut (a small, flanged, toothy ring) on a sturdy surface with the large end facing up. Position the axle with one end in the middle of the capnut's ring, and firmly tap on the other end of the axle with the hammer until the capnut has been forced onto the axle.
Slide the axle through and across the back of the tricycle's frame, threading the end of the axle without a capnut first through one of the small wheels, then through the pre-drilled holes in the frame. Slide the other small wheel onto the free end of the axle and rotate the entire trike to lie on its side so that this second wheel is on top. Place the wide end of a capnut onto the free end of the axle and force it onto the axle by tapping firmly on it with the hammer.
Position a locking washer (a flatter form of capnut) in the center slot of a pedal, with the wide end facing the outside edge of the pedal. Place the pedal rod (a rod with four bends) onto a firm surface, then slide the pedal onto the other end of the rod so that the washer centers on its end. Tap firmly on the outside edge of the pedal with the hammer until firm.
Slide the main wheel onto the pedal rod and center it between the middle two bends. Press two wheel inserts (small yellow tabs) into the wheel near the axle and align the notches with those on the axle before tapping the tabs the rest of the way in with the hammer. Repeat this procedure with two more tabs on the other side of the wheel.
Secure the other pedal onto the pedal rod using the same technique as before.
Align the middle of the pedal rod onto the slots on the tricycle's two-prong yellow fork. Place a securing block (a small yellow piece that fits into the fork's slot) over the pedal rod. Drive a 1-inch screw up from the bottom of the block into the fork, then drive a 5/8-inch screw into the side of the block into the fork with a screwdriver using the pre-drilled holes. Repeat with the other side of the fork. Spin the middle wheel to test if these screws are too tight. If the wheel does not spin freely, loosen the screws a bit with the screwdriver before testing the wheel again.
Slide the single prong of the fork through the hole in the tricycle's frame. Slide the handlebars over the end of the fork, with the handles pointing towards the back of the tricycle. Drive a 1-3/4-inch screw into the front of the handlebars and another into the back with the scewdriver using the pre-drilled holes.
Though there are only three sizes of screws from which to choose, you may want to ensure that you use the right size by checking each with a ruler before installing it.
