these instructions, injury to the rider or to others can occur.
• Adult assembly is required.
• Continuous adult supervision is required.
• Do not add a motor to the product.
• Do not tow or push the product.

Reectors
WARNING: For your own safety, do not ride the bicycle if the reectors are
incorrectly installed, damaged, or missing. Make sure the front and rear reectors are
vertical. Do not allow the visibility of the reectors to be blocked by clothing or other
articles. Dirty reectors do not work well. Clean the reectors, as necessary, with
soap and a damp cloth.
Freewheel Brakes
