What age should a child start on a balance bike?

Across the reviewers we read, most parents in r/toddlers started their kids between 18 months and 2.5 years, with several noting proficiency within a year. Four-wheel starter models like the SEREED Baby Balance Bike are pitched at 12-24 months, while larger 14-inch frames suit 3-6 year-olds. The recurring advice is to match the seat height to your child's inseam so they can put both feet flat on the ground.it more than the cheaper sticker price.
