Designed for age 18 months to 5 years, the Mini Glider is designed for safe, learning fun. The newly redesigned 2012 model has a seat that can be lowered to a minimum of 11 and raised to a maximum of 18. This means the bike can safely accommodate children with an inseam of 12 to 19. The handlebar can also be adjusted giving your balance bike rider plenty of room to grow.
