Thanks for the advice. There aren't a lot of recumbents where I live, so trying one before I buy probably isn't an option unless I find one on craigslist. I didn't know if a lot of gears would be needed for riding around a flat residential neighborhood or not -- my single speed beach cruiser does fine except when riding against the wind. I hoped the rear wheel drive would make the Slingshot better than a Mobo, but perhaps not.
