Hint:
Hello bicycle friends,

our sales limit as a small business owner for this year has been reached.
Therefore, unfortunately, we can no longer place new orders for 2026.
Please stop placing orders for this year.
  • Availability: All items you can see online will continue to be available next year.
  • Deadlines: Only payments will be accepted for orders received up to and including July 19, 2026.
Even though we can no longer accept orders this year:
If you have or want to know any questions about an existing order,
which spare part fits perfectly with your beloved bike…
It is still possible to write to us by email to get your bike fit again.
Retrobike wishes you a healthy cycling time and is already looking forward to starting the new season together on January 1, 2027!
