Pros:

• Foldable
• Looks pretty nice

Cons:

• Heavy with the battery. Need some muscle to lift it.
• Not very well done in terms of quality. Seems to rust easily. At least mine did.
• Not enough power. Yes, can climb up small hills but quite slow at it. Faster when you start applying some foot muscle and riding bike manually.
• Construction is poor.
• Everything have to be finely tuned or it'll have issues. Like the disc brakes. Since gap is so small, it need to line very finely with the disc on wheel. Same goes for the bike chain.

So would I buy it again? Probably not. Unless they improve the quality of the bike. Right now, the construction is very poor. When biking over rough parts of street, I can hear the battery banging against the frame. Can't be good and won't last like this. And nothing to prevent thief from taking the battery away easily.
