Hi folks.

When I bought my Cube Hyde Pro a couple of months ago I was unsure what mounting points it came with. The Cube website listed none & the actual images used in their own site showed none. Bizarre. Anyway, I took the gamble that the images used were mock-ups & bought the bike. It came with all the standard braze-ons one would expect on a bike billed as a 'City Bike'.

As well as the usual braze-ons it had two additional ones on the front face of either seatstay. I couldn't figure out what these were for & assumed they were some form of alternative rack or mudguard mounts. I was wrong.

What it seems they actually are are mounting points for a frame lock. What a fantastic idea! No more having to remember to take my heavy lock with me on the off-chance I might pop into a shop or bar or whatever. A frame lock is always there. It's additional weight of course but to be honest I'm becoming increasingly cynical about the race to shed grammes here & there in the belief that it's going to make me any quicker. On a race bike? Yes. On a City or Utility bike? Not so much.

I won't be able to buy one until next month so that gives me plenty of time to do some research and buy the correct one for my particular bike. As you can see, my bike has balloon tyres so it's going to have to be able to accomodate those. It seems there are also various mounting options including using the brake bridge, zip-tie type carbuncles for frames with no built-in option & this..

It seems to fit my requirements in that it's designed for the mounting points on my particular frame & it's wide enough to accommodate my tyres.

There are some downsides to this design though. They aren't particularly secure compared to a big heavy U-lock and, because they have a 'retained key' system it's possible to lose the small solitary key when the lock's in use because it won't be attached to anything else in your pocket. There's also the rather big negative in that a thief could just lift the bike up & walk away with it.

On the plus side the lock linked to above allows the connection of an additional cable lock which would allow the bike to be secured to an immovable object. As I said though, my intended use would be for just nipping into a shop for a few minutes or sitting outside having a beer with the bike in plain sight.

I'll update this post when I eventually buy this lock (or another). If anyone has any knowledge of this type of lock feel free to chip in. All I know is what I've gleaned from the internet this morning. Many minds & all that..

Have a nice day
:cheers:

A so-called pavement or nurse's lock - my Rose has one factory fitted.

I've used it occasionally, and it's main weakness - thief lifts bike and carries it away - is not such a concern with a heavy ebike which is not easy to tuck under your arm.

A Dutch cyclist told me some thieves in Holland have a hook clipped to their trouser belt, so they can walk away with the bike as if pushing it as the owner would, but the (locked) rear wheel is lifted an inch or two off the ground.

The lock is a deterrent to anyone wanting to nick your rear wheel.

Not such a concern for the likes of us with our scabby Shimano hub gears, but those with £1,000 Rohloff hubs could find such a lock reassuring.

I'm not sure what you mean about the key, it can be on your ring with any others you carry.

Mine is welded to the frame, presumably a retro-fit one has some form of once only or 'tighten only' fitting, so you would need to make triple sure it fits and you want it to stay there before tightening the fixing.

If it's like the steering (un)lock I had, the key has to remain in the lock whilst you are riding, so you are continually taking the key off the keyring and putting it back. Inevitably there are times when it doesn't go immediately back on the keyring, followed by the key hunt when it's time to ride off.

With my lock of this type you have to insert the key to deploy it, so it cannot accidentally come on while riding.

In other words, it's locked open (no key), latches shut with the key, and springs open with the key when you want to unlock it.

That's clever. The Bastards!

Yes, that's exactly what I fear happening.



Perfect!

That's a thought. Ouch!

I'm just back from a beer run to the supermarket. I parked next to two very nice road bikes, a Cube & a Scott. Neither were locked. When I was leaving I spotted the owners at an adjacent till and they were buying beer. When we got outside I discovered they were both German, didn't think anyone would steal their bikes & didn't have any way to carry their FORTY-EIGHT bottles of Becks home other than under their arms and walking the bikes.

I have a basket. And a lock.

I had one of these fitted to my CX before it became my commuter. Perfect for popping into the shops and with the additional cable allows the front wheel to be locked too.

Considering one of these....wrestling with such questions as “
  • what size bolt is needed for my Specialized Sirrus (which has the same “lugs” as the picture at the start, don’t want to add fitting kit if it can be fitted easily anyway!)
  • which one to get, & where to get it? (Lightest v strongest - Axa Victory plus cable seems a decent combi, but not cheapest...Defender comes with a fitting kit from Decathlon, but no chain in stock)
  • key locked in or removable? (In does mean it is always there....but must always be used, else a rogue could lock it and throw the key away - still probably better locked in, I guess)

I have a Defender, it uses metal mounting straps on my CX as I have no bolt holes, so no need for a fitting kit. Mine came from a shop in Holland, might be an expensive import now so if you can buy in the UK all good.
The key is locked in whilst the lock is unlocked, and can only be removed once it is locked.
