Hate to be negative, especially when you know somebody put a lot of work into the project, but I’m not seeing any real advantages here:

1. It offers connectivity which the rider may or may not want, OK. Cant’ really say that is an advantage.

2. It has regenerative braking. How much can it really extend a ride? Also, on a bike, unlike a car, if you run out of volts you can keep on pedaling, so again, I’m not really seeing the necessity.

I think a bicycle needs Bluetooth link like the proverbial fish needs a bicycle. I can just see it… ‘Road assistance? Help, somebody hacked into my wheel!”

But what I do expect from a power-assisted vehicle is to provide propulsion. How much can this bike provide? Not a lot, if all it is going to do is store the energy that *I* would have to provide in the first place. Electric engine without batteries is about as much use as a combustion engine without a petrol tank – just more dead weight to lug around. It might look good in Copenhagen which I believe is flat as a pancake and where you don’t need much power assistance anyway but I can’t imagine it being any use anywhere else.

Like most ‘green’ solutions it answers a question that nobody asked and ignores the actual needs of most people.
