I quite like the Kryptonite U-lock "wheel extender" idea - but I'm less attached to Kryptonite as a company - and even less so to the Messenger series of their locks, which is the only one that has this feature.

Kryptonite Messenger Mini U Lock

Are these wheel extenders available separately? I can't find them as a separate item on Kryptonite's website and don't see anyone else offering them either. Are they called generically something else?

  • I can't visualise how this would work. D lock is to go around the rear wheel-rim and the seatpost? Where does the extender go? Or the D goes around stationary object and seat tube, and the wheel extender goes around the rear wheel? – Criggie Feb 19 '17 at 0:38

    Two variations: 1) frame+rear wheel with extender on parking post; 2) frame on parking post with extender to front wheel. My ebike has a weird diamondless shape so I can't do a Sheldon to secure the rear wheel so it'd be frame to post with extender on the rear wheel, which has the $$$hub. – RoboKaren Feb 19 '17 at 1:29

    I've seen a chunky cable lock (the sort that expects a padlock to close, with an eyelet at each end) that worked for this purpose - essentially the D lock was the padlock. – Criggie Feb 19 '17 at 6:16

    TBH, that just looks harder to use than a cable, plus has the side benefit of providing the thief with extra leverage to break the lock. – david1024 Feb 20 '17 at 22:29

    I'd just get a heavy-duty cable. – Daniel R Hicks Apr 22 '17 at 1:11

Kryptonite does not sell that separately right now(source: am a Kryptonite distributor), but I'll bring it up to them, see if they are interested in offering it.
