Hi again
I Just thought this information might help others in the future, 'don't' fit this motor kit to the front forks of the Dahon Jetstream P8 the forks are aluminium with quick release drop outs, I had to change my plans and buy a Dahon Speed D7 folder for this kit it turns out that the Speed D 7 is one of the few remaining chromolly steel framed folders with chromolly steel forks, made by Dahon, most of their other bikes are fitted with Aluminium forks which are not Ideal for front wheel motors.
