Well that’s interesting. The RMK E2, currently under development by RMK somewhere near Helsinki, not only uses a hubless rear wheel, its motor is the rear wheel. Now we’re thinking seriously outside the box. Wait, what’s the unsprung weight going to be on that rear wheel?
Word is the prototype is coming along nicely, with plans to have bikes on the road in time for summer. Great story and more pics over here at New Atlas.com.
