 YOUNG ELECTRIC Bicycle Assembly Guide
The following assembly information is only a general guide to assist during the assembly of YOUNG
ELECTRIC bikes. It is not a complete or comprehensive manual of all aspects of the bike assembly,
maintenance, and repair. Consult a certified bike mechanic to assist with the assembly, adjustment,
repair, and maintenance of YOUNG ELECTRIC bikes.
Step 1: ATTACH THE KICKSTAND

Step 2:PREPARE TO ATTACH THE FRONT WHEEL
Gently place it on a soft surface to prevent scratches during assembly.
Remove all zip ties and inside protective covers or packing materials. (scissors not included)
Step 3: ATTACH THE FRONT WHEEL
Step ❷
Remove the front axle bolt and shipping bracket from front fork. Remove plastic caps from front
wheel hub. Insert the front wheel into the fork dropouts. Make sure the brake disc is centered in
the caliper to avoid damage. Insert the quick release axle bolt into the front wheel hub and tighten.
Do not over tighten the quick release and do not use any tools to increase leverage, close it firmly by
hand. There should be no play in the front wheel.
All quick-release levers should be inspected before every ride to be sure they are fully closed and
secure. Failure to properly close a quick-release lever can cause loss of control of the bicycle resulting
in injury or death. Make sure the wheel is properly seated and the quick-release lever is properly
closed.

Installation guide
① Remove plastic caps from front wheel hub.
② Unscrew the adjustment nut from the skewer, remove outer spring and slide the skewer through
the front wheel axle so the quick-release lever is on the same side of the chain.
③ Begin to thread the adjustment nut back onto the skewer, but do not tighten too far. Allow
enough play so you can place the axle into the fork drop out.
④ Slide the wheel into the fork dropout slots. Insert the disc rotor into the center of the disc brake
at the same time you are inserting the wheel axle into the fork drop out.
⑤ Move the quick-release lever into the open position. With one hand on the quick-release lever
and one hand on the adjustment nut, start to hand tighten the adjustment nut until you start to
feel some resistance against the fork.
⑥Try to close the quick-release lever. If it closes easily, open it up and tighten the adjustment nut
further. If it is too difficult to close, open the quick- release lever up and loosen the adjustment
nut a little and try again. Do not attempt to tighten by turning the quick-release lever. The quick-
release lever is for closing, the adjustment nut is for adjusting the tension.

Step 4: ATTACH THE HANDLEBAR
Remove the handlebar clamp from the stem by removing all screws with M5 Allen wrench. Insert
the handlebar into the stem and reinstall the clamp. Make sure the handlebars are aligned with the
front wheel before tightening and the stem is not set above the maximum height indicator. Tighten
all screws evenly in crosswise pattern. Make sure handlebars are in preferred position before final
tightening of screws. Tighten the 2 bolts on the stem. Make sure all screws are tightened evenly to
ensure maximum stability of handlebars.
Make sure all fasteners used to secure the handlebars and stem are torqued according to specification.
Loose handlebars could cause the rider to lose control and result in serious injury. Do not extend any
component beyond any minimum insertion mark. Damage to bike, property, serious injury or death
could occur.

Step 7: ADJUSTED SEAT HEIGHT
Loosen the seat post clamp bolt with M6 hex key . Adjust the seat post up or down to a comfortable
height, while ensuring the seat post is inserted into the frame past the minimum insertion point .For
your safety, the saddle should not be raised above the marker on the seat post.
The seat assembly should be adjusted with the seat centered on the rails and level. It is
recommended to add some grease to all threads and binders on a bicycle, especially on the outside of
the seat post. Otherwise it may corrode over time and not be able to be adjusted again.
Improperly adjusted seat height could affect the rider’s ability to reach the handlebar and pedals
resulting in unexpected movement, loss of control and serious injury or death. Follow these
guidelines when adjusting the seat height. Always ensure the seat post minimum insertion marks are
below the seat clamp and cannot be seen. Ensure the seat clamp is locked and the seat cannot move.
