Balance Bike, Magnesium Alloy Frame Toddler Bike,Lightweight Sport ing Bicycle with 12" Rubber pneumatic tires,Adjustable Seat for Kids Ages 1-5 Years Old.

Despite my best efforts in tightening the bolt to its utmost limit, the handlebars remain loose and continue to slide up and down.

The bike is excellent overall, save for a welding error on the handlebar attachment, resulting in a protruding steel lip that hinders smooth turning and produces an unpleasant scraping sound. I plan to attempt filing it down; if unsuccessful, I'll return it, as it's unrideable with such stiff handlebars for my 6-year-old.

Unfortunately, this bike is on the small side for my recently turned 9-year-old. Even though it consisted of a few parts, assembly was less than straightforward. The black plastic rings wouldn't fit properly into the metal components, requiring me to trim them slightly. Consequently, I'm somewhat let down.

The bicycle is an excellent choice for my granddaughter; it boasts smooth movement and a lightweight design, which she thoroughly enjoys.

Assembly of the bike proved to be a straightforward task, and my 4-year-old daughter has taken an immediate liking to it. She has had no difficulty in maintaining her balance while riding.
