The chain looks a bit short, which is probably why it was hard to use in the choker configuration. I have the [12KS chain in a 6 foot length](https://www.abus.com/us/Home-Security/Chains-and-Cables/Maximum-Security-Chain/12KS-loop) and it easily locks up 2 bikes. I combine it with their [Ultimate 420 U-lock](https://www.abus.com/us/Recreational-Security/Bike-Safety-and-Security/Locks/U-locks/Ultimate-420) as well. You could probably lock 3 bikes using the U lock and chain, possibly even 4.
