FATWHEELS® adaptive training wheels provide heavy duty bicycle stabilization for children, teens, and adults riding small and large bikes from 16" to 27". Designed for riders with autism, ADHD, developmental disabilities, balance challenges, or anyone needing extra support, FATWHEELS help build confidence, independence, and riding skills. Unlike standard training wheels that remain fixed in one rigid position, FATWHEELS feature an adjustable sliding wheel system that allows more adaptive movement over uneven terrain for a smoother, more natural riding experience. Our heavy duty bicycle stabilizers are ideal for special needs riders, larger riders, therapeutic recreation programs, and families searching for durable adaptive cycling solutions that grow with the rider.
