Hello
I have ridden a Nirvana, for the last two years, about 3000 miles a
year. Commuting, back and forth to work 8 miles, all year winter,
summer, spring and fall. I haven't had the first bit of trouble with
it. I work at a LBS, and get to bring it, inside, so it doesn't sit
outside in the weather. Just do the regular cleaning and lubing.
The seat was a little hard ar first, but my butt, got broken in.
And now it's like a easy chair. I also use it for the bike paths
here in Ohio.
