Hi OSM-GB and welcome to OSM! 

Thank you for helping to improve OSM. Since you have set your editor to en-GB, I'd better answer in English as well. Otherwise we could continue in German. 

You requested a review of your change. Unfortunately, I had to revert the change completely because there were some technical errors in it. 

description=cycleway=opposite, for example, makes no sense. You could use description to describe an object better, but that doesn't apply here. And cycleway=opposite would be used for situations where cyclists are permitted to travel in both directions on a road which is one-way for general traffic. But that is not the case here. 

Furthermore, you have set the number of lanes to 1, even though two vehicles can easily pass each other there. What you might be referring to is the lack of lane markings, which could be covered by lane_markings=no. 

Please have a look at the wiki to find out how to enter things, or feel free to ask here directly or get in touch in the OSM community. Nevertheless, have a good time while mapping!

If Scheulenstraße is not used for bicycle routing in any case, this is probably an issue for the router. There is nothing in the data to prevent this.
