Helping Kids With Disabilities Experience Personal Freedom and Mobility!

We are a Northern California non-profit organization dedicated to providing custom tricycles to children with disabilities.

Helping Kids Be Kids

Each Amtryke is custom-made and custom-fit for the child's special need.

The ability to ride a bike is often not a reality for children with physical or developmental challenges. Properly balanced and safely supported, almost any child can ride an Amtryke.  They are designed to address the special and varied needs of any individual with disabilities. 

Helps build important physical and life skills

Proven to build motor skills, strength and self esteem.

Fun for kids

It is fun to ride and offers the child the chance for age appropriate inclusive play.



"I haven't ridden a bike in 5 years.  I'm so looking forward to feeling more free!"


"I'm going to ride my bike to Roundtable Pizza!"


Joshua's mom is thrilled "that he now has the ability to participate in more physical family activities and that he has something that all the other kids have."


Aiden's mom is "excited that he'll finally be able to go outside and play."


"I'm looking forward to bike rides with my family."


"Now I can finally go with my family to walk the dog!"
