Here is another big idea. But will it actually work and enter the market? Nice pictures, but as usual all are computer drawings. What I want to see is a video showing the actual bike rolling under its own power, preferably at its top speed of 100 mph. And I think it is a little early to ask for a deposit. ::) https://electrek.co/2018/09/11/rmk-electric-motorcycle-without-hub/

Designers love the hubless look but it rarely makes it into production becausse there's nothing practical about it.
The reality is that that's a really bike hub motor, which means a lot of unsprung weight at the rear. And it won't be as strong as a rim or spoked wheel or as easy to service/replace. And you won't be able to change gearing to you liking.
Then there's what you mentioned: These are just renderings. Anyone can make a pretty rendering of a bike and make bold claims of its performance. Building a working bike and demonstrating that performance is much harder. Making that bike work for production is again harder than that.
Then you have the realities of creating a dealer network and being able to service the bikes. Imagine putting down $2k for this bike, waiting years, putting down another 24k, and then when something goes wrong having to ship it back to the manufacturer to service it.
I'm kind of tired of all these concept bikes asking for pre-orders. Not interested until you have a real product and real business plan.

I certainly agree with you, Caza.

Here is another article.( In Swedish)
Im looking forward to hear how the weight of the wheel compares to a normal bike. The article says they aim to show it in february 2019, but they have not found funding for production (aiming for patents on the motor), so it will probably take some time before we see much more of it.

I certainly agree with you, Caza.
I see no belt to break (or chain to adjust) as an advantage.
I wonder how the rear brake works. Perhaps by more regen as the rear brake is pressed? Or is there a hidden brake in there somewhere?
