Which saddle for exercise bike?

[Devold]

We've bought a Kettler ergometer exercise bike this winther. It's a bike with an upright riding position. I got crappy joints and some back problems. That's why I want to ride in my living room all winther in stead of riding many hours at my gym, where I also train my back. When spring arrives, i will ride my full suspension bike and my other bike for commuting.

The saddle on the exercise bike is awfull though. Almost 27 cm wide and my legs are bothered by the wide saddle. We tried one of my expensive WTB saddles in stead, but it didn't work because it's not made for an upright position.

I'm thinking a saddle which is made for an 60-90 angle degree would be just about right?

And maybe 18-22 cm wide?

Can you recommend a saddle?

Cheers
