I’m not sure where you are staying, yes it’s in English and the company is very obliging. Give them a ring and pre arrange, pretty sure they will do something for you.

Unsere Tour war auf Englisch.

I believe it runs all year round but suggest you contact the company to make sure

I don't think it is that is expensive in that a bus tour of the city is not a lot less and this is much superior. Also I've gone on segway tour of Philadelphia and regular price was more but with discount I got, Philadelphia tour was not a lot less. I booked same day at tourist office because I think tour would be not pleasant in heavy rain and I heard it rains often in Bergen and it had rained heavy 2 days earlier. Light rain would be no problem. I don't know popularity of tour, but I think it also depends on when cruise ship is in port.

When I went there were 4 tourists an 1 leader. Leader said that was ideal. I would say it depends on the tourists. I'd say 8 would be a maximum assuming all the tourists are not particulary clumsy and are cooperative.

I would say generally it is not for handicapped. Main ability needed is to have some degree of balance on two feet and navigate similar to being on a bicycle.

About 2 hours- I think.
