Well done, you! While it's easy to laugh at e-bikes as somehow a soft option (they are, but so what?), they do get people out in the fresh air and, as you have to pedal, there is always going to be some gentle cardiovascular exercise. And, of course, they make light weight of any shopping.
I remember when I first saw them and realised that it meant the grandparents could enjoy a day out with the grandchildren. What's not to like about that? Also met a 70-year old out in the hillls who was still able to cycle around 100 km with the help.
There are still problems with them largely related to separate motor/gearing systems which mean that many people leave them in the highest gear, with the highest degree of support, which means they don't half accelerate at junctions, which is also where most accidents with them occur. I suspect we'll start seeing combined control systems so that people don't have to think about the gears either.
Another interesting effect they're having by driving up the average price of bikes, is that bikes are gaining status, which means people are more willing to spend money on keeping them maintained: so they go for regular inspections rather than being ridden until they start falling apart. Though I also doubt that you can get a really usable bike for less than £ 100.
