Our custom-made SecurityForBikes RL21 RoundLock super-compact padlock. Sold Secure Motorcycle Gold/Quad & ATV Gold/Bicycle Gold/Motor Scooter Gold approved with any appropriately-approved chain and also on its own (e.g. as a disc lock).

The RoundLock is lighter and a lot more compact than the Squire SS65CS whilst offering similar security at a much cheaper price. Note that this is a 2-part lock where the top section comes out completely and is then re-inserted sideways through the chain and into the female lock receiver. It may be slightly harder to use than the SS65CS as a result (although you typically need 2 hands to fit that lock to a chain as well).

Disc detainer anti-pick cylinder with 9 discs, protected by rotating anti-drill hardened alloy steel plate.

3 keys supplied.

Keyed-alike available at initial order only (not available retrospectively) when ordering more than one lock together, and only amongst other RL21(A) locks and/or DIB-Series D-Locks. These locks can't be keyed-alike with any of the Squire locks.

Very compact and a perfect partner for Protector 16mm chains at a great price! Not suitable for our 19mm chain unless the optional extra RL21A socket is also purchased and that is used in place of the standard RL21 socket.

The RL21 can sometimes be used with our Protector 13mm chains - it's a close fit and the manufacturing tolerance on the chains can make-or-break the idea of the combination. Check to see if we have the corresponding Package Deal available - if it shows as available to order then we have a batch of chain that fits the RoundLock!

This lock can also be used as a motorcycle disc lock - Check that you have a suitable opening that will take the 21mm diameter shackle in your brake disc or disc carrier. You can then use this with a chain when at home and as a disc lock when out and about.

The RoundLock is generally not suitable for 11mm (or, sometimes, 13mm) chains or for use with hasps, padbars, etc.

The lock body is 40mm diameter and in the locked position it measures approximately 77mm long overall. That excludes the the plastic cap at approximately 6mm thick.

21mm diameter shackle.

Weight: 0.55kg

Below is a short video overview of the SFB RoundLock, showing how it can be used with our Protector 16mm and 13mm chains and, with the optional RL21A socket, with the 19mm chains:

Excellent lock.

This lock is fantastic. So easy to use and super solid. If anyone tried to cut it, it would just soon in the chain. Many thanks to David for helping me select exactly what I needed to secure my motorcycle. One key fits 2 round locks and a D lock. That mak...

Great Lock!, because of the ball bearings and such if you leave this lock outside a lot it does need some oiling, but this lock is fantastic. An example of true engineering, doing a lot with a little.

Top rated lock & Top rated company

5 stars for the lock and to this company, couldn't do enough for you and kept you informed all the way through.
For something so small I can not see how you would defeat this lock, it's tough, solid and awkward to even try and attack.
