I want to make an Elf like velomobile. The frame does not look that hard and I like how they have a dual drive system. And I also like how they use a Nuvinci drive and a hub motor both of which do not need custom spoked on a wheel!
2 questions: Where are they getting those squarish aluminum extrusions that have 3 bolts to mount the hubs?
and my second question is what kind of custom fat hub are they using on the rear wheel that has a sprocket on each side. Where could I buy something like that. And yes I realize I will probablay have to custom spoke it to a wheel. the youtube video shows the fat hub on back tire. the drive system is explained at 1:45 in the youtube video.
Looks like earlier version used a welded bracket instead with a wheel that has slide out axel. I've never seen a slide out axel like that before. Never worked on a bike with disc brakes is probabaly the reason, lol.
