TiGrBlue Mini+ Bike Lock with Mount: Strong and Lightweight Flexible U Lock for Any Bicycle Electric Bike Scooter or Other Security Needs

Could be a small amount bigger, but nice bike lock. Looks quite hard to defeat on YouTube as well

Had on my eBike - bike got stolen within a month with the lock. Had it on tight to protect theft but they still managed to be able to cut if off.

First, I would like to point out if you need additional or replacement keys, you have to go through Tigr, and they sell them as a 2-pack, and it costs $20 plus $5 shipping. You cannot just go to a hardware store or locksmith store to get a copy.Second, this is a rather short-reach lock. As another reviewer here stated, I wish this had a longer reach, especially if you're riding an electric bike that might have wider frames.The Tigr Blue Mini+ is easy to use. It feels solid, yet lightweight. It's a good concept. The lock is easy to put on and take off. A reviewer here reported the lock failed eventually. Tigr sells replacement lock cylinders for $40 plus shipping.

The lock was lightweight but the bike holder had to be replaced 2X and never really worked well. The lock mechanism stopped accepting the key (both) so I'm in the market for a new one. It lasted about 2 years.

Ok I bought this lock for my new Ebike I did research and wanted something tough and extremely lightweight so I went with the TiGr mini + blue the first lock got lost contacted the seller and Jim the owner of the company contacted me right away sent a replacement ASAP and gave me his contact information if there's any problem. Top notch customer service
