This is the one I'm talking about, $75
Kryptonite Evolution 1055 Mini 10mm Chain Bicycle Lock , Black https://a.co/d/0xjPXNw
If your bike is worth over $300 then imo it's worth it, now that every douchebag has a mini bolt cutter in their backpack (around here)
That's the one!
If you already have a good pedestrian vehicle: a good bike lock.
I (and lockpicking lawyer) recommend the kryptonite evolution. Good balance of price and protection.
For a step up I recommend the kryptonite fahgettaboutit.
Either way, bolt cutters aren't getting in, and portable angle grinders will take a little while because the chain is annoying to grind.
I see too many expensive bikes chained up with thin little locks.
I was gonna say this.
$100 on craigslist or a local bike refurbishing place (where I got mine) will get you something that will last for years.
Throw in a $15 bike lock, a cheap returned helmet, and a $5 rear bike light and you're set for life.
I got one for $40 that's 1080p, and the "high endurance" sd card I got for $15 is still going 4 years later.
Don't overthink it. You don't need something fancy.
I bought a bunch of mechanical keyboards. I had "the mech fever". Several hundreds of dollars.
I bought a microsoft ergo keyboard on a whim 3 years ago and never looked back. It's perfect. I can type faster and have zero discomfort. I can't think of how it could be improved.
$60
I recommend the xaiomi one on amazon. Works great
Lockpicking lawyer's hydrolic bolt cutter exploded on it.
Angle grinders will cut through anything, but they're loud, and if you have a lock that takes more than 30 seconds to grind or 1 grinder disk, well why would the thief bother vs one of the easier targets?
Also tape an airtag somewhere on the bike.
