Hi Commuters--

I am a sometimes bike commuter and an always bike errand runner.
Basically I drive a lot to work but make sure almost all other trips
(groceries, errands, etc) are by bike. I am working towards
commuting more. I am seriously looking at a mtn bike
with 26" wheels. I rode an old mtb for years but have
been riding road bikes since. I find them zippier but I think
this is mostly in my head. I want a fast bike bc. the distances
are kind of large (the ones I cover).

Thoughts or experiences on this issue/question?

Best,
KV
