Hi Gooner,
I just purchased my first ebike on Saturday, I chose the Wisper 905 Torque and I absolutely love it. I was concerned when I first chose the bike because I was told that with a torque bike, you have to work harder than with a cadence bike but on a test ride I fell in love with the torque. I am 43 years old, 2 stone overweight and really unfit however, I collected my bike and cycled the 5.9 miles home and I didn't even break in to a sweat and at the end of ride I actually didn't feel like I'd done much exercise at all. Even the next day nothing ached so don't please don't be put off having a torque bike, my bike has a throttle too and I find that brilliant. To be fair, I can't vouch or any other bikes because I only tried 2 brands but if I can ride a torque bike and not feel any negative effects then anyone can.
