I like this bike but find it too heavy to heave up stairs. The battery comes out so it's useful when locking the bike up to remove the battery and recharge inside, or take it with you in a ruck sack to make the bike less nick-able. It's not been used much which is sad as it's a good solid ride and would be good on or off road. Downside is no dynamo lights. I fitted a rack and kick stand and mudguards as extras when I got it.
