What kind of bike would you recommend for an 8 year old girl who has trouble riding one? We think she may have some slight brain damage due to lack of oxygen during an anaphylactic episode when she was 2 from a peanut allergy. She's being tested now due to different problems she has to see if this is the case. When she's riding a bike she can pedal for a little bit but it's like her mind forgets to keep doing the motion and her feet slip off. It's very frustrating for her and I'm wondering if they make any kind of bikes that might help her with this.
