Schwinn SmartStart Kids Bike Assembly


This checklist contains important information regarding bicycle assembly and safety. It is intended to be a convenient general reference only. It is not intended to be a complete or comprehensive manual covering all aspects of bicycle assembly or safety.


Tools You Will Need

  • Adjustable Wrench
  • 15mm open ended wrench
  • Screwdriver (for bikes with stunt pegs only)

Step 1: Attach the Step

Make sure the fork is facing forward. Use your wrench to loosen the stem binder bolt so that it can be easily inserted the wedge-shaped part at the bottom of the stem, far enough into the steer tube that the minimum insertion mark can't be seen.

Tighten the stem binder bolt keeping the handlebars aligned with a front fork.

Step 2: Attach the Front Wheel

If the front wheel has a break, release the brake so that the tire can easily fit between the brake pads. The axle of the wheel should sit completely in the dropout slots with the washers located on the outside of the fork.

If the washers have hooks or steps, place them inside the small holes on the fork dropouts.

Center the wheel and tighten each axle nut gradually and evenly by switching sides until both are secure. If the wheel is not centered, loosen the axle nut on the side with the smaller gap. Shift and hold the wheel on center and retighten the nut. 

Make sure to refasten the brake when present.

Step 3: Attach the Front Fender

Using your wrench, remove the nut on the front of the brake.

Position the front fender so the fin is toward the back of the bike and the funder bracket is in front of the fork crown. Replace and tighten the nut.

Step 4: Attach the Saddle

Unlock the quick-release lever and insert the seat post far enough into the seat tube that the minimum insertion mark can't be seen. Alight the seat with the top tube of the frame and tighten the adjusting nut until the lever, when closed pulls the seat post firmly in position. Adjust the seat height as needed for alignment, rider fit, and comfort.

Step 5: Attach the Pedals

You will need your  15-millimeter open-ended wrench to complete this step.

Pedals are directional and conveniently marked for an L left and R for right.

The R pedal should be matched to the right-hand crank arm on the chain side of the bike, where your right foot would be if you were pedaling the bike, and is threaded in a clockwise direction. 

The L pedal should be matched to the left side crank arm, where you left foot would be, and is threaded in a counterclockwise direction. Start threading each pedal by hand two to three turns in the correct direction on the appropriate crank arm. Then wrench tighten with your wrench.

 Step 6: Attaching Training Wheels

Remove the outer nut and washer from the rear wheel axle. Align and place the brace stabilizer washer onto the axle, so that the notch on the washer fits into the frame dropout.

Place the wheel brace onto the axle and replace the washer, then outer axle nut. While holding the wheel brace in the vertical position, tighten the axle nut.

Make sure that the back wheel is able to roll on the ground when the pedals are turned. If it can not propel the bike forward the training wheels will need to be raised.

Step 7: Attaching Stunt Pegs

If your bike has stunt pegs included, make sure the axle nuts are in place and properly tightened.

Thread the pegs over the axle nut and insert a screwdriver through the peg holes. Turn the peg with a screwdriver to tighten. Repeat these steps for the remaining pegs.
