That's fine. But, we can all go buy the worlds best bike, but we have to pedal it. If you can't, but get this extra power, it's trouble - just like cars - so Insurance....
I'm not negative to e-bikes, they are a fab idea, but if that speed is available to anyone, like cars, insurance needed. A heavy e-bike landing on you, might get insurance claims for PI. I'm a fully insured cyclist , and it's been used both for me, and against me, so it's needed (all low speed actually - less than 15 mph).
I'm still not going to get one, they look great, but I still like suffering and swearing (broken spine 3 years ago). A recent ride involved 6 hours on the MTB a few weeks ago, lots of pushing (e-MTB would have also) and carrying down un-rideable stuff.. got home. I won't be doing the loop again soon as it's massively exposed (needs a good day that I got) and it's not very rideable - an e-mtb would be a liability at the weight.
