I have a Grit freedom chair, it basically has a single speed bike chain setup on both sides. The levers on each side are used to propel oneself. I like it and use it a great deal. I am considering powering up the front wheel on this chair. Not to replace my arms, but to augment them, much like my legs are augmented with my ebike.
I think I have two choices. 1, some kind of friction drive like Qiroll, or a scooter hub motor and tire. The dropouts(which are a bit different from the picture) are about 100mm and there is room for up to 9.5 inch tire 2 inches wide. I have 48V battery and charger with the bike, so would like to use those. I have looked at xiaomi scooter wheel and it might work. I have been down the aliexpress rabbit hole and unlike Alice, I came back confused...
Anyone have some parts they want to sell? or knowledge they are willing to pass on? thanks. Any input appreciated.
