We have the use of 3 electric bikes. They are cheap Chinese ones and the old adage ‘you get what you pay for’ applies especially to elecy bikes.
The electrics are shoddy to say the least, but once you get to know what’s what they are absolutely brilliant. Ours are 250w and are fine, but you can get bikes with larger motors.
We live about 1 1/2 miles from the nearest town and it is much quicker to get on the elecy bike and fire into town than to take a car and have to park etc.
On the continent they are much more popular – a mate in Germany says they’re more common than normal bikes.
I’m in the process of building a trailer with a hub motor at the mo.
And if you want a laugh take it to a party and watch people fly up and down the road on it whooping.
