Abus Bordo Alarm 6000A & Bracket SH 6000/90 holder review

The reason I went for this lock, is the 100Db alarm, even tough a folding lock has a flaw has flaws that make it possible to defeat, if you have the right tool for the job, like rivet splitter, or huge bolt cutters, but it’s most likely that a thief won’t have it. but if you leave bike inside a store, with camera, and people around, the the thief must be really stupid to try to steal the bike.

The alarm means the thieve can’t move the bike, it will result in the alarm beeping, and the thieve does more fiddling it will go on full blast, just a slight movement it will go off. so trying to defeat it even with the right tools will make a big racket.

For locking the front wheel to the frame, the lock is too short, and even rear wheel frame to a shop entry roof support beam, but frame to rear wheel it works well, and if there is a light pole it might work if you park it well, and pole is not too thick, so if it’s thin light poles it will work, and but front is too not gonna work on my Nicolai Geometron G1 size Large with 61 deg head angle, the front wheel is too far away from the frame.

But if there is a bike rack like this one, you can easily lock the bike to it.

but for bike with steep head angle it will work.

Insert and remove key properly & keep it lubed:

When inserting key make sure you move it in all the way and make sure to not rotate the key when taking it out, it will result in misalignment thus key won’t go in properly, so you will have to align it then insert key all the way in, so to spare your self from doing that, insert key in all the way, and when taking it out make sure to just pull it out carefully.

To make sure the key went in smoothly and did not freeze cus of water in keyhole, it came dry.

A closer look at the lock:

The lock comes with this holder.


A bad thing about mounting a bike lock on the bike is that it will be covered in mud, dirt, leafs, grass or what ever else that can get on it.

  • My testing shown that hard impacts to the bash guard results in the middle links of the lock popping out. So I can’t approve this solution for #mtb might work for light xc with impacts, but not #enduromtb the holder would also move side to side, leaving black rubber residue on the frame. Using only the strap provided did not work so well, but adding zipties helped to stabilise it but did not stop it rotating so from now on the lock will stay in the backpack. That was the plan anyway, I just wanted to test this holder but having a lock mounted to the bike will result in a dirty lock, as with everything else mounted to the bike won’t attach things to my bike, it makes no sense to me. I probably rode harder than this was tested, hit bash guide at rock fountain in city centre, I jumped over a stream, but I don’t think that was the problem, but I think the problem is hit the bash guard over and over, eventually the links popped out, seems like the impact made it pop out.

after just few days of testing I took the mount off, there was a lot of rubber residue on the frame where it was mounted.
