The above Dahon has been one of the lightest folding bike in market.
Is there anyone interested in discussing to convert it?
Its weight is less than 9 kg. And very reliable and good looking.
It has thin wheel of 70 mm from inside wall fork. The challenge is to find a reliable thin hub motor drive wheel.

Is there a picture in the post? I don't see it showing up. I'll put one in myself if you don't mind...

I have heard of people replacing their folding bike forks with some special wide forks so they could accommodate these 100mm motors, though I'm not sure where to point you to get an easy supply for that type of wide fork to fit your bike. I've not heard of any 70mm motor, but please tell us if you do find some. We'd be very interested.

I suggest you take your Dahon to your local bike shop and ask them if they could install a custom 100mm fork for you. It would probably be easier for a bike shop to sort though all the permutations of possible ways to do this than it would for you, and then it would be easier for you to choose a motor/kit for your bike because you'd have many more options, including our kit.
