What are FATWHEELS?

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.

Difference Between FATWHEELS vs. Standard Training Wheels

Standard training wheels are generally designed for young children learning to ride a bicycle. They provide basic side-to-side support, but many models have limited adjustability, lower weight capacity, and are intended as temporary learning aids. As a child grows or a rider needs more substantial support, ordinary training wheels may no longer be suitable.

FATWHEELS are heavy-duty adaptive stabilizers designed for children, teens, and adults who need additional balance support. Their adjustable sliding-wheel system offers a different riding experience from fixed-position training wheels. The wheels can be positioned lower for greater support, then raised gradually as the rider develops confidence and balance.

This flexibility allows FATWHEELS to serve as both a learning aid and a longer-term stability solution. They also accommodate a wider range of compatible bicycle sizes and rider needs. Correct fit is essential, so check your bike's frame, axle, wheel size, and kit requirements before ordering.

FAQs - Frequently Asked Questions

What bike sizes do FATWHEELS fit?

FATWHEELS offers adaptive training wheel kits for a range of bicycle sizes, with options covering approximately 16-inch to 29-inch bikes, depending on the model. Small and Large kits accommodate smaller and standard bicycles, while the Adult FATWHEELS Kit fits most 24-inch to 29-inch bikes and supports riders weighing up to 250 lbs. Since compatibility also depends on the bicycle's frame design, rear axle, and wheel configuration, use our Fitment Guide to identify the right kit before ordering.

Can I install FATWHEELS myself, or do I need a bike shop?

Yes, many customers can install FATWHEELS themselves using the supplied hardware and step-by-step installation instructions. FATWHEELS also provides instructional videos to help make the process easier. However, installation requirements vary depending on the bicycle and kit. If you are unsure about axle compatibility, bracket positioning, or proper assembly, we recommend having a qualified bicycle mechanic assist with the installation. Always check that everything is securely fitted before riding.

What conditions or needs are FATWHEELS designed for?

FATWHEELS are designed for children, teenagers, and adults who need additional bicycle stability and balance support. They can benefit riders with autism, ADHD, developmental disabilities, balance challenges, coordination difficulties, or other individual needs that make riding a standard bicycle challenging. They are also suitable for larger riders and people who want additional stability while cycling. Families, physical therapists, occupational therapists, hospitals, schools, and therapeutic recreation programmes use FATWHEELS as part of adaptive cycling activities.

FATWHEELS offers different kits depending on bicycle size and rider requirements. Current listed prices include:

  • Small FATWHEELS Kit: $169.95

What warranty comes with FATWHEELS kits?

The warranty does not cover normal wear and tear, wearable components such as tires and bearings, improper installation, modifications, misuse, or damage caused by accidents or neglect. Proof of original purchase is required for warranty claims.

Do you offer support for physical/occupational therapists prescribing FATWHEELS?
