I was called the local dahon dealer to find out the fork dropout and material of the D3 curve, to see if I can fit a motor on it...
The smallest motor I could find was the 83mm cute motor...(thanks jerrysimon)
I was not so happy to hear that D3 curve's fork was only 74mm wide, but thankfully I was informed that it was made of cromolly not alloy as I first thougt..
The dealer though, told me -as soon as I told him that I would spread the forks 9mm (possibly up to 11mm to fit the nuts and bolts needed)- that it will not be safe to do this as it will affect the welds and therefore risk a crack!!
So I am asking, what do you think is the case?
1) does dahon welds and materials so inferior to bromptons that will indeed be a problem?
(I am saying this because Jerrysimon already did this succesfully on his brompton which has a 75mm fork)
2) Is cromolly tougher to spread than steel, so that is the problem?
3) Dealers ignorance and/or repulsion for electric bikes (that are not the dahon boost they sale at a ridiculusly high price) was the reason for discourage me from that project...
I want to believe that the right answer is number 3, but I need to know... I am running out of time here, tommorow I sould decide whether to buy the D3 or not and I dont want to buy a bike I will not be able to convert to electric...
As he stated all 16/20in dahons has 74mm forks and I think I have seen a lot of front mount dahon conversions in the past... Is there somewere a smaller motor or the did it the same way as I plan?
