I'm coming up 63 y/o.
I've got a light weight Carrera Cross city , a Mycle Ebike Climber and and Engwe, all good fun and capable of what they were designed for.
I've got a Halfords Crosscity folding E-bike, it's ace, it'll tackle most hills, folds up quite compact and will do between 14 to 21 miles on a charge dependent on terrain.
