What bike lock should I get? Should I splurge on a diamond lock or what would be best performance / price?

At the end of the day, all locks are deterrents more than anything else. Even with an unbreakable lock, I’ve seen wheels stolen & frames ruined by thieves.

Personally, I try and lock my bike up where I can keep an eye on it & I have an AirTag under the bottle cage just in case. I think that’s about the best security you can get.

That said, kryptonite u-locks are great. All of their products are pretty good (and affordable). The only thing I don’t recommend is a cable lock like the one you have

My bike costs me $800 used and my locks all together cost me about $430 …I have different locks for different use cases…and I still don’t have a grinder resistant u-lock – that’s the last one I plan to add to the set.

I knew I wasn’t always going to have a “cheap” bike but I will have these locks for years ..worth while investment imo…The question isn’t should you splurge on a better – it’s how much are you willing to lose on the bike with a lesser lock….

I have a Kryponite Cinch chain lock, a Hiplok Gold chain lock, 2 Foldylock Forevers, and an older OnGuard u lock…

I don’t carry all with me at once but usually have one chain, and 2 foldies on the bike at all times (big cargo ebike so weight isn’t a concern). I use one chain to lock up in my garage, and the u lock is in the backpack for quick stops where high security is less of a concern…

I’ll just leave here LPL vid on his bike lock
