Hi,
we would like to share a build we were a part of - DIY electric wheelchair attachment.
On the market you can find 'ready to ride' solutions but most of them are slow (25km/h) and the range is not so long.
The concept was simple:
-50km range
-as fast as possible (but still safe at the same time) +/- 45km/h
We started with regular wheelchair and Rapid S-1100 SL ebike kit with 12,5Ah 48V battery:

https://ebikers.eu/en_GB/p/Battery-Guru-BG600-battery-12,5-Ah/42
Motor was laced into 20" fatbike rim with 4" tire
To make a frame one bike had to be salvaged - for headtube and fork
Frame and wheelchair are connected in 3 spots for safety reasons
Battery is shrink-wrapped so enclosure had to be designed and made
It was 3D printed with PLA and metal sheet was added to add durability and rigidity.
PLA has low melting point so in future it will be remade with ABS or PETG or fiberglass
It took only one night to print
First test (there is no headset, that is why everything is shaking)

The frame still needs painting but for now everything works fine

The wheelchair wheels will be changed
