Late Summer Special 2025

Grand Nicholas

Open House

13.December2025

Open House at the end of the year

As every year, we ring in the most contemplative time of the year with our Grand Nicolas Open House.

We cordially invite you to our Open House on December 13, 2025. From 10:00 a.m. to 4:00 p.m., you are welcome to explore our company premises, take a look at our CNC machine park, discover our production of high-quality parts, or observe our mechanics at work and ask them any questions you may have.

At the same time, you can expect a day full of highlights: In our store, you can shop to your heart’s content, try on the latest fashions, and relax while finding Christmas gifts for your loved ones. Of course, our latest custom bikes will also be on display, providing you with fresh inspiration for your own projects.

We will also provide refreshments – with freshly baked waffles and many other treats to round off your visit with us. Come by, bring your friends and family, and spend a special St. Nicholas Day with us, full of bikes, shopping, and refreshments.

Don't forget! Our highlight of the year

The Thunderbike magazine & calendar

Our popular Thunderbike Mag is back in print with all the highlights from 2023. Take a look and gather ideas for a new project.

There’s also a calendar – grab our double-sided calendar with lifestyle and custom images.

If you can’t make it to us, you can of course also order the magazine and calendar online.
