I've never understood the appeal of electric bikes. It just seems lazy to me. I'd feel guilty if I relied on the motor instead of burning calories.
I use the cars for transporting the family, or to go long distances quickly. I'm not averse to cycling 25 miles if time allows, and I've also managed to carry all sorts (like IKEA furniture) on my folding bike. I also wear my work clothes (jeans and t-shirt) when cycling on my commute, demonstrating that lycra is totally unnecessary!
I can only assume that electric bikes are for people that wouldn't normally cycle, or whose routes are prohibitively hilly.
Would be keen to hear the use cases of anyone here that uses one.
