dont save by buying anything but the best locks you can afford. fwiw i use A good D-lock to quickly clamp the rear wheel to an immovable object, for all the occasions I leave the bike for 3-5 mins. And a 4ft grinder resistant close chain and similar shackle for locking up for longer periods in public places with the dlock.

And remember to include the cost of locks for any insurance validation.

 

good news is now your on an ebike the weight of the locks is an insignificant factor

 

 

Don't people remember the rule, spand 10% the value of the bike on a loock

 

Better still TWO locks per bike

Not much will deter a grinder , even a portable one will cut thru most locks in 120 - 180 secs.

Any cable type can be bolt cropped easily as will most D locks or locks less then 14mm in dia, 16mm dia is the optimal dia D lock that can with stand bolt cropping even from the larger 3ft bolt croppers.

I've got a flat bar folding lock and an old D lock plus a motorcycle cable lock. I'm going to swap bike rack tomorrow so may look at attaching them all to bike or rack. I don't really want to spend any money unless I have to as have enough locks and having read through posts I think 2 or more locks is best. See how it goes but I think I need to buy that Onguard especially for that price.

I think some of you guys have things out of proportion. Bikes4two has it right. You should buy a lock according to the risk.

 

When you park your bike at the shiop, cafe, doctor, dentist or somewhere like that, the only thing you need to guard against is casual and opportunist thieves, who won't have heavy cutting tools with them. Typically, they have wire cutters and hacksaws, which can deal with really cheap locks, like thin cable locks, but wouldn't be able to handle even a cheap D-lock.

 

The next level are those that stake out gyms cinemas and places like that, where they know that bikes will be parked there for some time. They sit in the car with a pair of boltcroppers and wait for you to go into the gym with your sports bag. As soon as it's clear, one jumps out of the car crops your padlock, chain or cheap d-lock and rides off.

 

The worst situation is when you have to lock your bike in a public place repeatedly, like when you live in a flat or when you use your bike for work. If it's a decent bike, sooner or later someone will want it, study your security and come back the next day with appropriate tools. There's not much you can do about that except try to make it as difficult for them as possible.

 

There's no point in paying a lot of money to get a high quality lightweight bike if you have to spend hundreds of pounds and add several Kg of mass to keep it secure.

 

To summarise, you should buy a lock and bike appropriate to the risk of someone nicking it.

 

Personally, I use a £15 Squire armoured cable lock that is not too heavy, protects against casual thieves with anything up to bolt-croppers, and has kept my ebikes safe for 12 years and my motorbikes for 15 years before that. The most important thing is to lock a non-removable part of your bike to non-moveable object to stop anybody from carrying away your bike. That's a disadvantage of D-locks. You can't lock to a tree, drainpipe or lamppost, and a separrate cable isn't really going to help, as the casual thieves would probably have a pair of wire-cutters.

Another aspect you might like to take into consideration is insurance. Some insurers will require lock of adequate security to insure bike.

There is no such rule. You (or somebody else) just made it up.

when its necessary to leave a bike exposed in public I strongly suggest insurance is the only guarantee and if you have invested in good locks dont forget to include their value in your bikes total evaluation.

Are you REALLY that naive ? https://support.kryptonitelock.com/hc/en-us/articles/231014107-How-much-should-I-spend-on-my-bike-lock-

 

"Kryptonite suggests that you consider spending 10% of the total cost of your bike towards security".

 

"What's your opinion on how much to spend on beating thieves in relation to bike value? Years ago I read the recommendation was 10% of cost of your bike. Is that still worth it? "

 

I suggest you read and learn from others who know more than you it is a known fact

"Kryptonite suggests that you consider spending 10% of the total cost of your bike towards security".

Of course the do. They sell locks.

 

How about this then. I suggest that you spend 20% of your income on me. I look forward to getting the money soon if you're that naiive.

Are you REALLY that naive ?

 

Lock I posted is cheaper than yours and offer better security, so who is naive here?

 

I have nothing against spending money on locks and security. I just pointed out there is no 10% rule. As Seneagle mentioned above, Kryptonite sell locks, so it is in their interest to encourage people to spend more. Anyway it was just a suggestion, not a rule.

Edited September 30, 20232 yr by Az.

It may seem a tad pedantic but its the difference between 'rule' and rule. Your 10% 'rule' is a guideline [mention=40353]Saracen[/mention] not a rule..

Sometimes language is very important and in a technical arena the difference between a rule and a guideline is Vast.

 

but we all get it so,, all good
