I would like to stipulate up front that I love my commuter bike—a mid-1980s steel Bridgestone RB2. Classic without being ostentatious, it's gotten me where I need to go for 20+ years. But I don't always lock it up.
It happens, right? You're halfway to work and realize that you've forgotten your lock. You loaned it to your kid and forgot to get it back. Or you have the lock but forgot the keys. Now you're out in the world, stark nekkid in a harsh environment where 1.5 million bicycles are stolen every year, even when they’re locked up like Fort Knox.
What are you gonna do? |
