Hey Page... so, here are some websites that I found that include different types of bikes... I still haven't really figured out a way to get them paid in full or partially even, given that the bike is not per say a 'primary mode of transportation' like a wheelchair and such. I asked our PT and OT and they couldn't think of anyway to get them covered.... But hey, if the 'Bike Lady' and the 'Big Daddies' can somehow join forces and make it happen for Luke... that's awesome... although, I must admit I am kinda chuckling at the names! :)
