I'm completely new to bicycling in the city, and I moved to Brooklyn a year ago. Here, bike theft is almost as popular as bicycling. I have a dirt bike. (A Giant, Women's Sedona, if that matters) and have just bought a U-Lock. However, the seat on the Giant Women's Sedona bicycle is a quick-release, and I really don't want it to get stolen.
The few bike seat locks I have found, I'm not sure if they'll work-- specifically this or this, although the second is a bit pricier. But I want to be able to leave my bike for hours unattended without worrying about the seat being stolen.
So if anyone has any ideas, that would be great! I'd be happy to provide more information if needed.
Thanks muchly in advance.
