How/ where do you want to ride?
How much are you willing to spend?
'Bents are nice, but get fairly expensive If you want one that do well on climbs and poor roads.
Cruisers - if geared properly - are comfy for shorter rides.
A full-sus MTB can provide a cushy ride too.
If you have no intention of pushing it, you can even get away with a fairly inexpensive one.
