an accessible bike for Ava

Ava is six years old and has global developmental delay and a severe seizure disorder.  She is still undiagnosed to this day despite travelling all over the country and even having Harvard medical look into her.   Despite her everyday struggles she is the happiest little  girl I know.  Her word she uses most of all is Good! Good! Good! 
We are trying to get Ava an accessible bike.  She was able to borrow one for six weeks from the IWK hospital and LOVED it!  She loves riding a bike and it is something that will help her to grow and strengthen and be a kid!
