We bought Caz an ebike last year but not much used yet. They changed the law last year(or maybe 2016) so the motor can only assist now and also restricted speeds. I am not going to type what as I donít know.
I was thinking of getting one myself before the changes as I cannot peddle but missed the boat, not sure if the new laws only affected new bikes or if retrospective. Just had a look on inter web and it doesnít say watts but is 8.8ah and top speed is 15.5mph so not sure if itís something different you are looking for
All that said the one Caz has (Pendleton Somerby)seems to put more power in as needed, it is a very steep hill we live on and she can go up at a gentle pedal. I havenít tried it myself yet as wanted to wait until it gets some scratches on it first
I got myself a mobility scooter instead which I find great for getting round when we go anywhere.
