Motorcycle trials certainly inspired bicycle trials in various locations. However, it is unclear how often this occurred and how serious these activities were in individual cases. Röhrnbach in the Bavarian Forest is a good example of how, despite or perhaps because of close contact between young people and motorcycle trial riders, bicycle trials did not take place. The goal was motorcycle trials, and just as ten years earlier in Ebstorf, bicycle activities in Röhrnbach came to an end as soon as the main participants had the opportunity to switch to motorcycles.
Emil Jahreis, who is sitting backwards on his Ossa in the photo below, taken in Röhrnbach in 1974, writes: "The children certainly imitated us with their old, converted bicycles, simply trying to ride up or down an embankment, but also sometimes riding on the rear wheel. So it wasn't about building sections, but just being there. Among the children are the brothers of Max Thoma, including Alois and Georg Thoma, who are still successful motorcycle trials riders today (2013). Later, Max and Hansi Thoma converted a 50 cc Zündapp for trials riding for their younger brothers."
The photo from Röhrnbach is a great picture. You can see how the young people are imitating the motorcycle trial with their bicycles: not only are they wearing the clothing that was common at the time – rubber boots and caps – they are even copying the pose of the motorcycle trials riders taking a break!
