For kids with less strength, you may want to consider restricting the turning radius straight ahead. This keeps the front wheel from turning back and forth as the child pedals. Feel free to adapt the AmTryke to your child. Add on anything that will help it work for your child, or take off anything your child does not need. We have had parents and therapists remove the pedal cups, add Velcro straps for the wrist, and add blocks to the pedals for short legs.
Some therapists like to reverse the relationship between the foot pedals and the hand cranks.
The only way to accomplish this is to remove the chain guard, unfasten the chain, rotate the hand cranks one half turn, and reassemble the chain and guard. Any local bicycle shop can easily do this. If you are reasonably mechanical, you can do it yourself. Send us a picture of your child with a big smile on the AmTryke. This shows the volunteers who support this project the benefits of the AmTryke project.
