I’ve got an ecargo bike and it is the best bike I’ve ever had. It is expensive , but same as a mountain bike and ride it more.
To others points I haven’t given up the car completely, but round town clocked up 400 miles din 6 months doings shortt tripst to the shops,child care etc. Amazing how it adds up.
For me without electric it would be a slog, whereas with the motor you can do it easy without needing a shower etc.
Also it’s a bit like a vw transporter, high outlay, use it for a few years and still worth a fair bit.
I’ve got a Harry v Larry ebullit with a 8 speed hub gear (worth having something you can change gest without pedalling when you stop at the lights in the wrong gear, as you can’t just pick up the rear and spin the wheel to get it in the right gear !)
