1. Rotate the fork for 180 degree before assemble the front wheel (the brake can be in front of the bike)
2. Pedal threads are different from left side and right side. L / R signs are marked at the spindle of the each and every pedal, make sure that they’re assembled at the right side (whilst you ride at the bike, left pedal to your left side, right pedal to your right side). The precise side pedal has a right-hand thread(eliminates counterclockwise, installs clockwise). The left side pedal has a left-hand thread (eliminates clockwise, installs counterclockwise). Thread both pedals into the crank arms so far as you’ll by hand. Then Fully Tighten them with the wrench. If the pedals don’t seem to be fully tightened, it should get loose and damage the threads, we can NOT be accountable for such damages.
This implausible be offering is not going to last long at this worth, so do not miss out!
