I'm loving my Crosscity (though being a newb it's the only e-bike I've ever ridden, so admittedly I don't have anything to compare it to). I'm using it for a 20km round commute and some leisure rides - it ate up a very hilly ride around Hampstead (36km in all), and I got 40km from a mostly flat East London run, full power most of the way. Had to replace the seat with a more comfortable sprung/cushioned one, though. Can't vouch for its longevity, and it's very slow without the battery (don't know if any more so than other bikes of it's type). Love the way I can drop the handlebars and stow the pedals so it takes up less space in my hallway. Weight apparently is a bit better than other folding e-bikes, but it's still very unwieldy to lift when folded.
