HELP Kalkhoff Chopper bike

[Berks22]

Hi.
I don't know if this is the right topic, but I hope for your help.

I have old Kalkhoff bike at home. The bike must be from the 70s.
Very similar to the Raleigh Chopper MK1 but it is from the Kalkhoff Company.
Did you have any information on this bike. Maybe manufacture year, name, model... Maybe even the value of the bike.
Unfortunately, I can't find any information about this bike anywhere, or it's very scarce.

Bike is a little dirty on that photo but it is in excellent condition and no rust.
Thanks for the answers.

Kalkhoff is a German manufacturer, been in business since 1919. I'd guess it's somewhere in the early 70s, this one was listed as a 1972

You can probably pin down the date by using date codes on the Sturmey hub...

I sent an inquiry about this bike directly to the Kalkhoff company. And they answered me...

Thank you very much for your message.

Unfortunately, we do not have data sheets or other information for such older models.

We are sorry that we could not support you in your request.


So there is still very little information about this bike.
