Like d8veh I have seen that bike several times...it was presented at Shanghai by an Eastern European guy,he told me he was the designer of the M1 carbon bikes I saw at Friedrichshaven. I found him a difficult guy to pin down on price,spec,plans,delivery...he seemed more interested in the technology than making a business,so I lost interest.
I saw the same bike at last years bike show at the NEC,shown by a company I think was named Madhog,same story really they hadn't thought through the marketing,they didn't know whether to direct sell or though shops and had no price.
The Bofeili motor has been around for maybe 5 years,I visited their factory in China,a lovely family business...Mum does the books,Dad was the engineer and their daughter the marketing....but I felt that despite a lot of enthusiasm they lacked the infrastructure to give confidence in their product,it was not powerful and the BPM hub was simpler and cheaper and backed by Bafang technology.
Whilst I liked the bike,the guy wouldn't let me test ride it and he was talking about changes before he released,it seemed a good prototype not a production bike.
The bike was nicely styled,it was light but at this price level you do need a very professional presentation to give customers confidence to buy and nobody has done that.
