From the reviews:
"Hey all, this bike rack does the trick. I have two bikes, one trekking and another mountain bike. The rack easily fits the two and even though my mountain bike handles are very wide, the frame makes it so it fits facing forward. Also, I have it free standing (no nail in the wall) and I don't see this tipping at all. "
Price is $115.95
T. Wirgart has built it in wood and plans to paint it. Nice!

" A rear axle spacing of 170mm is the emerging “fat-bike standard” though other rear axle spacings have been used for fat-bikes most often from smaller builders including 165mm, 160mm and 150mm. Originally, available hubs drove this difference as builders adapted hubs from tandems to fat-bikes. The 170mm dimension got a push towards standardization when Fatback owner Greg Matyas began specing them on Fatbacks back in 2008. With the explosion of fat-bikes more hub makers are offering wider hubs and the 170mm width has become the defacto standard for symmetrical fat-bike hubs."

Yes, they are heavy so need more than 250W.
I believa in this case it is more like 1000W.
Old school, mad Max style, I like it!

Rear-wheel drive m42 military bike from -57 at 1000w. about 50 km range. Tried to keep it typical of the time and hide the electronics, but hydraulic disc brake unfortunately became a necessity to stop the bike as the drum brake does not really do the job.
