You won't need to worry about bobbing. The rear suspension is quite stiff and small travel so it smooths out smaller road bumps but no bobbing.
The front does go up and down, but that is also not too big, and besides it isn't sapping much energy according to my current understanding. It may even help (again according to my current understanding).
Thanks for the inputs.
I may still try one out in future before deciding.
In no hurry.
I had a nice foldie that had a rear elastomer suspension.
On the flats, it was a nice ride.
But if I pushed hard for speed or climbed, the bobbing was a PITA.
Later on, I tightened the suspension to the max to reduce the bobbing.
It improved, but I can still feel the reduction in pedal force to actual movement.
Thats why I'm apprehensive about rear sus bikes (birdy, moulton).
But perhaps they are better thought out in this respect.
Still have to try one out in the end.
