When it comes to bikes & scooters Retrospec is our family’s favorite! We’ve had the Baby Beaumont balance bike, cricket toddler bike, scooter, and now the Koda Plus bikes with training wheels in two sizes. These are great bikes & helmets! My 20 month old is practicing her balance on a 12” Koda Plus. She wears an XS helmet. My 4.5 year old has mastered the 16” Koda Plus and wears a Small helmet LTKKids LTKHome LTKActive
