Instead I'll do the opposite.
I'll point out upfront, I own 5 bikes, I run one of the largest cycling forums in the world, and I run one of the largest cycling clubs in the UK. I get cycling.
I like it. The FlyKly.
I like it because it allows a rider to keep their existing bike, and yet to retrofit for a really reasonable price an electric motor.
I like it because the vast majority of the weight within the wheel isn't a moving thing, the batteries are fixed.
I like it because the 30 mile range, whilst not suiting my 18 mile commute for a daily charge, actually does suit the vast majority of cyclists that I know who only commute fewer than 10 miles.
I like the 1,000 cycles, which is probably 900 in reality, is actually a few years of use for the average cyclist. Even most cycle commuters don't actually cycle 7 days a week, and those do diligently do so on all work days only do so for 220 > 250 days per year.
It hits all of the sweet spots:
1) Can I keep my existing bicycle?
2) Can I just get the electric bit and not pay to replace all of the other bits I have?
3) Will it just work and be easy to install?
4) Will it help me on my commute?
5) Will it realistically last a couple of years?
6) Is it priced such that I can afford it?
For the majority of cyclists I know, the answer is yes to all of the above.
I think it's got a good chance, which doesn't mean I'll be buying one but then I'm not your average cyclist.
PS: FlyKly, you show several times the use of the wheel on a brakeless fixed-gear bike. That's just for the aesthetics right? Or is the wheel fixed compatible such that you're fine with people skid/skip stopping?
