Thanks for the independent destruction testing of the Foldylock Compact (the top one is only by the manufacturer themselves)! This is so good.

[@bikelockwiki]

Exactly what we’re here for! Thanks for watching :)

[@jeffreyschmitz6403]

One rarely mentioned feature that I love about the fully lock compact is that two or more can lock together which makes it really nice when I'm out for a ride with my wife. Two together provides a substantial length lock that's easy to lock two bikes with.

[@bikelockwiki]

This is true, and even Seatylock don't mention it much.

[@andreluna2660]

Exactly the video I was looking for. Thanks

[@matthewlallemand7715]

Great review, very helpfu and thorough l as I am waiting to receive a Foldylock for the new bike I have coming this week!!! Thank You

[@bikelockwiki]

I'm glad you found it helpful. Thanks for watching. Which Foldylock did you go for?

[@nox2889]

So glad I found your channel. You deserve more subscribers. Keep it up!

[@bikelockwiki]

Really appreciate that! Are there any locks/security products you're particularly interested in? Thanks for watching

[@nox2889]

​@@bikelockwiki The ABUS Bordo SmartX 6500 is interesting to me but I find it hard to justify it's price without seeing a very thorough review. I like the idea of alarms on locks these days and wish there were more options out there.

[@bikelockwiki]

@@nox2889 Agreed, I'll test it soon when I compare "The Best Smart Bike Locks". Have a good weekend!

[@freewaytf]

Absolutely perfect coverage, you deserve much more attention

[@bikelockwiki]

Thanks! Is there anything else you’d like to see in our reviews or any constructive criticism you can provide?

[@andreluna2660]

Try with the most secure Seatylock they have. It's 18/18 security scale.

[@bikelockwiki]

@@andreluna2660 will give it a go!

[@chaxologist2961]

First! Just bought a Foldylock Compact of the same blue color last week to further complement my multi-lock setup with the the Mason U-lock and Viking Chain lock which makes it easy to color-code my different Seatylock keys on the same keychain! Has buttery-smooth locking mechanism like the other 2 locks. Great as a primary cafe lock and a fantastic secondary lock to secure my electric scooter for over an hour especially for my up and coming new Segway Ninebot F2 Pro e-scooter!

[@bikelockwiki]

The locking mechanism is a dream. I probably didn't give it enough credit in this review!

[@gottaluvtheserenity]

Very thorough, thank you.

[@user-iy4yy4be7n]

Great content ! Hope you keep it up :)

[@bikelockwiki]

Thanks for the feedback :) Is there anything you think's missing from our reviews?

[@michaelfreund]

Wow excellent video and thank you for not trying to be hip or goofy and use ridiculous “cool” music or camera tricks. I will come back for more.

[@bikelockwiki]

Thanks for the feedback. I agree, bicycle security is an important topic that needs to be clearly explained without distraction. Glad you found this helpful.

[@danielgvozdovic7381]

Thank you! good and fair review

[@bikelockwiki]

Thanks for watching! Anything else your would have like to have seen?

[@bikelockwiki]

Thanks for taking the time to watch my latest review. Feel free to share any feedback you have on my testing procedure (I'll use it to improve future content).

[@StephenDannatt-vn3pi]

Thanks for the video a great insight. I have just bought a Haibike e-bike and are looking to beef up my security and like the look of the foldylock at about £90 but it cut very easy with the angle grinder and spooked me . What lock would you recommend please

[@bikelockwiki]

For an e-bike you’ll want a lock with the Sold Secure Powered Cycle Gold or Diamond rating. Personally I’d go for a grinder resistant lock like the LITELOK X1, but the ABUS 54 Mini may also be a good option.

[@bikelockwiki]

If it’s grinder resistance you’re looking for, the LITELOK X1 and X3 are great along with the Hiplok D1000 and DX1000

[@StephenDannatt-vn3pi]

Thanks for that info much appreciated 👍@@bikelockwiki

[@Dazdigo]

You should get a hydraulic bolt cutter. They are smaller than traditional cutters and can apply a lot more force with less effort.

[@bikelockwiki]

Will be getting hold of one soon. I'm looking for something that will allow me to record a precise reading of the pressure exerted upon failure.

[@Doc.Holiday]

@@bikelockwikiI second that! I know you purchased one and look forward to future content. Thieves used one to steal my last bike. I just purchased a large Mason Hex Mason. I’d like to know if it will survive a hydraulic bolt cutter attack. Grinders are their own alarm. I can defend against them.

[@bikelockwiki]

@@Doc.Holiday it definitely would survive against a standard hydraulic cutter. I’ve tested my recent cutters against a 5mm folding lock, and the cutter’s blades warped. I opted for a higher quality cutter as well 🤷🏻‍♂️ Could have been old blades. We shall find out how good hydraulic cutters actually are when I review the best cheap bike locks!

[@bakerdow9884]

Which lock is truly resistant to angle grinders? Thanks

[@bikelockwiki]

The most resistant locks are the Litelok X3 and the Hiplok D1000, but with enough time these can still be cut

[@SmoothbassmanStudios]

Great video!! That's why I have e-bike insurance! No lock stops the angle grinder!!

[@bikelockwiki]

Nope, but they’re getting closer. The Skunklock Carbon is one to watch atm!

[@ryeem8043]

Thanks bro I've been eyeing my neighbors bike for a minute 😂😂😂😂

[@bikelockwiki]

😅👮🏻‍♂️

[@az101]

Minute?

[@cooloutac]

I never even heard of that Kryptonite Lock. The 790 is the one i have and its orange.

[@bikelockwiki]

Nice, the 790 is the best Kryptonite folding lock available at the moment.

[@Thomas-yr9ln]

I have a Abus and Andy lock but I dunno the name of the other.

[@bikelockwiki]

Which ABUS are you using? I've never heard of an Andy lock. Where did you get it?

[@skyrliecaceres6548]

Nowadays they’re carrying angle grinders😣no lock is safe! Best thing is a gps tracker

[@bikelockwiki]

Check out the Hiplok D1000 and LITELOK X3 :)

[@ig0lka]

You need to saw in weight, holding it in your hands without clamping it in a vice!!!1!

[@bikelockwiki]

The testing we conduct is designed to produce results that are more comparable. If we removed the vice there are more uncontrollables affecting our results. In short, the results we gather from testing are not supposed to reflect how a lock would perform on the street.

[@AFV85]

Thers always 2 when go to steal a bike thanks to KZbin videos their learning the ways the locks are weak

[@bikelockwiki]

KZbin videos or not, thieves are going to steal bikes and will find their weaknesses regardless. It’s better to educate cyclists on what specific locks are designed for and how to use them appropriately.
