they will be available at one time.... I dont know exactly when, but I do have 20 on order with Dahon just for good measure. They will come as a stem only without the light .... the light will be available seperately as well at a later day.
I think at this time the production of stems is somewhat limited and 100% go onto production bikes ..but I am positive that eventually they will catch up .....
Its going to be more money than the Aber Hallo for sure.... but than its a little more involved with the clamping and such so it should be more ...

Thanks Thor
