Probation time, bicycle & alcohol

Hello together. I tried to find something suitable about the search function, but was unfortunately unsuccessful. In general it is true that you can have up to 1.6 promille blood alcohol on the bike, as long as you do not show any driving abnormalities. If you lie below and get involved in an accident, you still have a problem. So far so good. Now there is for beginners up to 21 the 0.0 promille limit instead of the otherwise usual 0.3 promille limit (without driving abnormalities) at Kr aftfahrzeuge. My question is now whether this 0.0 limit of promille for beginners also applies to the bike? My driving instructor at the time only commented with ‘On the bike may have up to 1.6.’. I don’t care if I can cycle with my buddies even more cheerfully with the bike through the area after the drinking tour. I have a job in a beer garden and there it is common that, after the shop is closed, you still drink 1 or a maximum of 2 beers together. Up to me after The house is ~6km. I’m only interested in whether I can still (legally) ride my bike home after the 2 beers (only residential areas and dirt roads). I’m 18 and still have about 7 months probation time before me. I just don’t want to have a police car driving over the way and I get trial time extension, ASF, fine and driving ban for 0.2 promille on the bike. Greetings.
