My husband and I have decided to go with the Xtracycle for hauling the children around until they get big enough to ride on their own. Now that brings us to a new dilemma - what bike to attach it to? We don't have any bike lying around to convert, so that's not an option. We'd like a bike we both can ride (I'm 5'3", he's 5'9" ish), and that will have good brakes, since it will have 250+ pounds worth of passenger when hubby is riding.

We are considering a Big Dummy (Surly), Radish (Xtracycle-made, not out yet) and Electra Townie Commuter. Any other bikes we should consider? Anyone have a Big Dummy or Electra Xtracycle setup? What do you think?

Hubby is really in favor of the Townie Commuter, but I'm a little afraid of those roller brakes. Anyone used those before? I did a search here and couldn't find anything on them.

Any and all input is welcome! (I know you ladies are not afraid to share your opinions ) Thanks!
