My answer. I putter around, sometimes do 'casual' 25 mile group rides, trails. But I'm just an old slow fat guy on a bike.

My mini-velo is the most practical bike I've ever owned.

For 30 years I rode a huge 27" 10 speed Schwinn Varsity, with StingRay high rise handlebars, basket on front big enough to hold a 30pack and a rack on the back. It was awkward to transport, awkward to store and a real b*tch to get in/out of our house. What a beast. Loved it. Had a variety of other old big bikes, too.

Schwinn broke. At wife's insistence, dump all my other bikes cluttering our house. Started looking around for a replacement that was easy to transport/store. Ended up with a folder (FS9). It lives in my trunk, when we travel it fits on the rack folded. Anyway I loved the way it handled. And with racks, very practical. But, I live in a very bike un-friendly city. Jumping curbs and doing sidewalks is a necessity. Folding bikes do not like being manhandled like that.

Saw the advert for the Nano ($299) and tried/like it. It is a full foot shorter than a 700c bike. Lot easier to get in/out of the house. It's been on many a bike party. Now, it's my main errand/grocery/hardware store bike. Heck I'll walk it around in the Safeway/Home Depot and when the basket is full, I check out and go.

BTW, since it is only 5 feet long it easily fits in the back seat of my wife's 1991 Camry.

Just me.
