Here's some more information. My son is the one doing the route, and he would be using an electric bike. Point being, the hills are no issue, but stairs are absolutely out of the question. I would hope there is an easy route so he doesnt potentially get lost. It isn't clear to me whether going into Inwood Hill Park from 218th st will avoid the stairs. Perhaps it is best to go through Broadway and VanCourtland. I woudl prefer that he avoid Broadway due to traffic.. Is Bailey ave good? Also for navigation, he usually used Google, but in this case, maybe I should give him a Garmin Edge. Are you guys familiar with the Edge? Is it easy to input directions via RidewithGPS and does Garmin give easy queues on turns?
