Zulu Three and Zulu Four Assembly Instructions

Step 1: Attach Handlebar to Stem

Using the supplied 4mm hex key, unscrew the four bolts holding the stem face plate to the stem and remove the stem face plate.

Position the handlebars on the stem. Center the handlebars. Make sure the cables are on the front of the bike as illustrated.

Reattach the stem face plate with the four bolts. Use the supplied 4MM wrench to tighten firmly (observe torque rating labeled on stem).

 

NOTE:  Tighten the bolts in an X pattern as illustrated. As you tighten, pay attention to the gap between the stem and stem face plate. The gap on the top should be even with the gap on the bottom

Step 2: Attach Front Wheel

Locate the quick release assembly.  Remove the nut and one of the springs.

 

Find the arrow indicating direction of rotation on the front tire.  Lay the wheel on a flat surface so that the arrow indicates a counter-clockwise rotation.  Insert the quick release skewer through the hub.  Put the spring and nut on the opposite side of the hub.  Keep the entire assembly loose for now.

If this is the first time installing the wheel on the bike, the brake pads will have a black plastic spacer between them. Remove the black spacer. After the spacer is removed, do not pull the front brake lever until the wheel is installed. If the front brake lever is pulled without a spacer or wheel in place the brake pads can squeeze together and will need to be separated again before the wheel can be installed.

FULLY insert the wheel assembly into the dropouts at the bottom of the front fork. The quick release handle should be on left side of the bike (from the rider's perspective). Make sure that the brake rotor slides between the brake pads.  If the brake pads are compressed too close together, gently push them apart using a flat head screw driver or a butter knife (But don't use a sharp knife!)

Tighten by turning the nut on the right side of the skewer until slightly snug.

IMPORTANT:   Make sure that (1) both sides of the front axle are fully inserted into the front dropouts and (2) the nut on the right side and the quick release washer on the left side are FULLY SEATED inside the raised lips on the dropouts.

Tighten the quick release lever completely by pushing it up towards the fork. If the quick release lever feels too tight or too loose, adjust using the nut on the right side of the axle.

Step 3: Attach Pedals

Screw the pedals into the pedal holes in the crank arms and tighten with the supplied 8MM allen wrench. 

Step 1:  Loosely thread the pedals into the pedal holes in the crank arms.  The pedals come labeled with "R" and "L" stickers to indicate right and left.  The left pedal is reverse threaded and must be turned counterclockwise to tighten.

Step 2:  Tighten the pedals by inserting the allen wrench into the pedal axle from the side of the crank arm facing inwards towards the bike.  From this side you must turn the right pedal counterclockwise to tighten and turn the left pedal clockwise to tighten.

Pre-ride Check

Before each and every ride, be sure to check the following for the rider:
  1. Make sure all bicycle components are tightened and free of debris.
  2. Check air pressure in both tires.
  3. Make sure the axle bolts/nuts or quick release fittings on the wheels are tight and properly secured.
  4. Make sure the saddle is properly positioned.  Generally, for young riders we recommend the saddle be adjusted so that the rider can get both feet on the ground.  Consult our bike fit guide.
  5. Make sure the brakes are working. Rider should be able to operate the brakes easily while seated. Make sure the rider understands how to use the brakes. All Prevelo pedal bikes have front and rear handbrakes.  The Alpha Zero has only a rear hand brake.  The Alpha One has an additional coaster (pedal) brake.  Ask the rider to demonstrate the ability to brake by starting and stopping several times in a safe location.
  6. Make sure the rider's helmet is secured properly.
