Nope im.judging you against my fellow club mates who are very decent climbers, but cannot climb the welsh hills at 15.5mph......not even the professionals at the tour of britain did it and you are in no way on a par or better than themAh, you are making the classic mistake of judging another rider against your own standards. Lol indeed. 250W is a third of a horsepower, which ain't a lot, it doesn't have riders whizzing up hills like in the G Tech ads, and the assistance ceases at 15.5 MPH.
And how remiss of me - Happy Birthday Johnny. Enjoy the last year before the big one
