4 reasons not to buy

Some owners report damaged bikes upon arrival, including bent or scratched frames, warped wheels, and staples protruding through the seat.
The expert and numerous owners say the seat and handlebars require frequent readjustment due to weak clamps and bolts that don't tighten properly.

Bottom line

Joystar's Roller is a budget-friendly balance bike for toddlers. It scores some points for easy assembly and an extendable warranty, but as the saying goes, you get what you pay for. The number of damaged bikes reported suggests poor quality control, and the grips and seat materials wear quickly. True, the tires don't require pressure checks and won't puncture, but they offer little traction and wear out quickly. Additionally, seats and handlebars seem to require constant readjustment. Unfortunately, most balance bikes at this price point suffer similar issues.
