Found one on the internet for 250,00 euro's.
Bought another one for my wife and a spare one for parts.
The bike is built by Dahon in a limited edition of 500.
Parts are not to be found.
The frame is carbon and front fork and rear frame are crmo.
Rear hub is nexus 7 coasterbrake.
Driven by a Gazelle belt drive.
The weight is 16.4 kg.
In 2014 we went to the F1 racing track at Spa franchorchamps in Belgium.
The road from the camping to the track was a bit scary (with all the want to be racers on them)
so we decided to take a little B road.
It started vertically but hey we had a carbon bike and SEVEN speeds.
I guess you know what's coming. It took us 1,5 hours (5km) and we were dead at arrival.
Upon return home i would make the Tranza electric. Busy busy busy no time bla bla never came to it.
Then winter 2016 we went to Monte Carlo and Spain.
The camping in Spain was situated on a HILL and the ride to the village was to say the least
a workout.
SO this time back in Amsterdam, no more excuses GET ON WITH IT.
I own a bike shop so parts come easy.
I had already build an electric "granddad" bike (Burco "crossframe" 28 1/2 wheel size) based on a crystalyte set, in 2007 :

Far to heavy (40 kg) with old nicad battery and Nuvinci 1.
Ordered a set which was developed for a Brompton.

The motor in this set is for 78 mm dropouts without rollerbrake.
I insisted on a rollerbrake so I got a different motor.
Shop refused to tell me the brand. "the motor is specially made for us"...
NOT it's a:

The battery was situated on the front pannier. Motor and battery on the front resulted in
ridiculous steering behaviour.
So battery on the rear carrier and motor in the front.
Everything went a oke, fitted the motor in the front fork connected the wires and we where up and running!
1 2 3 4 5 speed of the nexus 7 where all useless.
So I installed a nexus 8 hub.
Minimal change…
Oh well change the gearing then. Oops no parts available from Gazelle.
So here comes the Gates Belt drive.
Started with 60 in the front and 22 in the rear. Again minimal change.
Now 70 in the front and 22 in the rear this seems to work.
Now only 1 2 3 of the nexus 8 are useless.
