She had one go on the 1000w DIY I mentioned in the op, and that scared the crap out of her so she's a little put off, I need to get her to try the Cube on eco mode and see that it's a totally different ride. She did say she wants to come out with me and she'll ride my old analog Rock Hopper I have in the shed, she's pretty fit but I still think she's going to have a shock when she finds riding uphill isn't as easy as it was the last time she rode a bike many years ago.
