This is just outside the neighborhood, but since so many folks bike in Columbia Heights, I figured I'd post it -- looks like there's a new bike shop.
The place is called DC Bicycle Stations and the sign on the window says "rental, service, sales." Hopefully they aren't as snooty as most bike stores! And it's nice to have one close by.
They're at 2204 14th Street NW.
