Kryptonite Evolution Series 4 Standard Lock with EZMount Bracket 2 Worth the money over series 2 - needs some sort of water seal Se*** I have been using a series 2 for a about a year now and bought this as I would be leaving my bike outside overnight in boston more often now. This was after having a bike stolen by a cut cable lock previosly. These are great locks, the mechanics of them are much better than the 2. Much easier to use because the lock bar goes straight on, instead of hinging like the two. The extra bar thickness does make a huge difference (beleive me, I had to cut them every so often at bike shops I worked at (with owner receipts)). I have much more piece of mind leaving my bike out at night. My only suggestion is to check the inner dimension if you want to get your front tire and frame around a bar. It works for mine, but it is much closer due to the added thickness in the U. Be aware also, this weighs a lot more than the 2, but once its in my pack I dont notice much. EDIT: I lowered the review to two stars because the lock is already starting to get jammed. I leave my bike outside often. My bike gets wet and still works. This lock does not. Once any moisture gets inside the lock, it gets jammed and you are forced to fight it to get it open. There is no seal to keep water out. I might expect this if I was to leave the bike locked for a month, not when I use it everyday. I know I could oil it which would help, but when I carry this in my bag, I dont want oil dripping all over my stuff. Its hard to not look like a thief when you are pulling on your lock with full force. B000NMAAEQ US
Master Lock Bike Lock Cables with Key, Blue, Green, and Red 3-Pack of Keyed-Alike Bicycle Cable Locks, 6 ft. Long, 8127TRI 1 Terrible quality Elaine A.*** The very first time I used these, all three keys broke. One of the locks does not lock at all. Awful, awful quality. B000XHBKOU US
Pinhead Bicycle Locking Skewer Set 4 They make me feel a bit safer about locking my bike up Cesar *** TLDR: I don't have to worry about the front wheel and seat being stolen. Getting the skewers on is a pain. The seat skewer was especially difficult to get right. I work in the Bronx. My job requires me to visit up to 9 houses in a day. My bike is literally what allows me to not have to take the incredibly slow bus system we have here. I have an electric bike that is pretty expensive. When I initially got it I looked on the internet and asked friends what a good locking technique would be. Most recommended 2-3 locks and taking the seat with me. These skewers allow me to have one folding lock that attaches to the downtube of bike. I feel pretty comfortable knowing that someone won't take my bike when I'm doing my rounds. Keep in mind, my bike is only ever locked up outside when the family cannot accommodate my bike indoors, it's only locked up for 30 mins at a time, and I do not leave my bike locked up overnight. I know that an especially determined thief MIGHT be able to get to it, however I think these skewers would make them think otherwise. My only complaint is that the seat skewer was especially difficult to get on. There was a time when I thought it was secure only to have the seat go completely down during a ride. After securing it really tight my seat does not seem to have moved since that incident. Make sure you take the key for this whenever you ride and you should be okay. B000XTPNZK US

Kryptonite Kryptolok Series 2 Mini Bicycle U-Lock (3.25) 5 Super Awesome U-lock R *** I've been using this product since 2008, and still using it. (Yes, I take my sweet time getting back to product reviews). Anyway, if the Kryptonite name doesn't give it away, this product is truly amazing. As many bike enthusiasts will agree, a U-lock is a much greater thief deterrent than chain locks (although using a combination of both is best.) I originally got it for my road bike on the Berkeley campus. It came with a bike attachment, so I just clip it onto my bike when I'm on the road. The size of the U-lock is perfect for my needs, since anything bigger becomes cumbersome and will not fit when attached to my bike frame, and anything smaller will not allow me to lock my front wheel with my bike frame. For those of you looking for a good bike lock, I say shilling out a few extra bucks is a small price to pay for something that will last a long time, not to mention peace of mind. Highly recommend. B001J3NH2K US
M-Wave Bicycle Cycling Bag 1 Not for a serious commuter Jo*** I ride 25 miles round trip, 3 days a week to my job, and stuff bags with clothes and my lunch. Occasionally I put a bike lock into the bag if I was running errands after work. The Good: Easy to Install Nice reflectors, good night visibility. Rear mesh pockets fit my tail lights beautifully. Easy to take on/off, making them perfect for errands for me. The Bad: Stitching on one of the bags tore off, and rendered bags useless after one months riding. I was not putting groceries, or laptops or anything particularly heavy in the bags. Recommend to not buy these bags. B001P9EWKE US
Two Fish Lockblocks U-Lock Mount 3 There isn't a great way to do it Came*** I used these to try and mount my u-lock to my bike frame. There isn't a great way to do it, and when I did find a way that worked, my bike lock rattled too much to bear. That being said, they were designed to mount a lock to handlebars, not a bike frame.

Kryptonite Kryptoflex 1218 Key Cable Bicycle Lock Bike Lock 1 Lock stopped opening after 2 weeks Al*** This lock feels more solid than most other cable locks and it worked well while it lasted. After only 2 weeks of regular use in good weather I came to my bike to discover that I could not get the lock open. I came back with the spare key and was still not able to get it open. I was eventually able to get the lock off with a large amount of force which left the key slightly bent. I have not been able to get the lock open since. B005VMO49U US
Abus Bordo GRANIT X Plus 6500/85cm (33.46 in) black - Folding lock, Bike lock, Security level 15 1 What's the attraction? Eliza*** To save my life, I will never figure out the popularity of this lock. I've never had a bike stolen, but figured it was time to up my bike-security game. The requirement to use a key is a negative, and it weighs a ton. But the biggest issue is that it takes two-three minutes to lock and unlock it. It's awkward and unwieldy. It's such a hassle, I'm tempted to go back to my good ol' Kryptonite, but I know how easily they can be clipped. I hope the engineers are working on a more convenient, easier-to-use model.

Guard Security 968 Heavy Duty Hardened Steel Square Link Bike Chain,Black,36 x 30 x 1.8 inches 5 3/8" hardened steel for a bargain Eric*** The best protection you can get from a bike lock is either from a heavy duty U-Lock, or a hardened steel chain; and even then, if a thief really wanted your bike, he would be able to steal it. You want just enough of a nuisance that they'll move on to the next bike. After many days of research, I settled on this chain and an Abus 92/80 Solid Brass Monoblock. If you're looking for a 3 ft 3/8" hardened steel chain, this does its job at a fraction of the price compared to the Trimax chain, or any other competitors. I'm currently living around a "safe" area so I justified my purchase of this decent 3/8" chain. If your area is more prone to bike thefts, I suggest you get the Trimax or even a thicker Abus chain (also sold on Amazon). The canvas/nylon blend covering is actually pretty thick and should adequately protect your bike from any scratches. Three feet is barely enough to fasten my rear tire and frame, if you prefer more give, I suggest you lean towards the Trimax. The links are indeed square and are slightly yellow from a special zinc coating. The welds don't look perfect, compared to the product photo, but they're pretty decent for the price. The chain itself weighs about 4 pounds, luckily my chain and lock fits around my waist when I ride. B00LOABMPM US
Kryptonite Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, 5 Heavy but very solid.

I mean if someone really wants your bike, bolt cutters would get through this but it won't be an easy grab. I would recommend. B016GZWRY4 US

KUAT Sherpa 2.0 Durable Lightweight Aluminum Compact 2 Bike Transporting Hitch Rack with Cable Lock & Foldable Tire Cradles | 5 Good Rack and Easy to Use cth*** This rack is light, easy to use. Love that it allows for your hatch to come up even when bike are loaded because of the additional swing down. Comes Pretty decent bike lock with 3 keys. I do recommend getting and additional lock though, but that’s just me. The rack isn’t very heavy so it is easy to put on and take off when not using bike. Some automatic car washes won’t allow you to drive through with rack on, so it is really easy to take off and drive through and put back on. I thought the price was a bit much, but I was wrong. The price is right, and you don’t need those overpriced Thule and Yakima racks...this one is perfect. B01FNDCTQG US
TG-RK4B102B 5 Quick, easy and it did the trick. Amazon C*** It matched the product description, was straightforward to install, and carried 4 bikes on a couple camping trips so far. It took a little finesse to fit two adult and two teen bikes on; but once you get them on, you lock each bracket with a set screw so it’s easier subsequent times. And be careful if you decide to release the pin to drop your tailgate while the bikes are still attached, it works but it’s pretty heavy when fully loaded. And the hitch lock and extra long bike lock we’re nice touches so we could grab food without wondering if someone was going to abscond with our bikes. B01KD9AQ92 US
Bike U Lock with Cable - Via Velo Heavy Duty Bicycle U-Lock,14mm Shackle and 10mm x1.8m Cable with Mounting Bracket for Road, 4 Great, Heavy Duty Bike Lock al*** I use this bike lock daily, as I work in the middle of downtown. It is constructed of much heavier gauge material than standard locks from the local big box stores. I did have a bit of trouble finding a comfortable place to mount the U shaped bracket, but I now just take the lock off and keep in my backpack with the cable when using my bike. B01MS8VFPM US

KAC Premium Bike Rack for Car, SUV, Hatchback Mount - 2" Anti-Wobble Hitch & Quick Release Lever for 2 Bikes - Heavy Duty Bicycle Carrier, Easy to Assemble/Install - Tire & Frame Straps Included 5 Great Rack for Ebikes or Others Pat*** I have a Ford Escape and had a 2" trailer hitch (recommended for eBikes) installed at a local truck specialty store. I searched for a carrier that would accommodate the extra weight of eBikes and not break the bank. I purchased the Overdrive Sport 2-bike model for multiple reasons: It is tailor made for the 60+ pounds of eBikes, it accommodates any bike tire size, even the 4" versions, the rack tilts down even with bikes loaded so that I can access the rear lift gate on my car, it is adjustable in width of bike, wheel width, etc. and it comes with security features that include both a hitch lock to the trailer hitch and a bike lock to secure loaded bikes. The entire hitch folds up toward the back of the car when not in use as a carrier. This saves space in the parking a I recommend the 2" receiver model over the 1.25" for eBikes because the 2" offers greater weight capacity and strength. All in all, this is one of the best purchases I have made. I am completely satisfied with the quality and features offered by the Overdrive Sport 2-bike carrier. And the price is so much less than comparable other brands. B07DP53LCV US
Aduro Sport Bike Lock Cable, Bicycle Master Cable Lock with 4-Digit Combination Lightweight Bike Chain Lock 4-Feet 1 Stuck locked after a few years Todd B*** After only a few years, the lock is stuck in the locked position. Simply locked it up in my garage over the winter, just in case someone got into the garage, and now the lock will not open.

Lixada Mountain Bike Pedals,Mountain Bicycle Pedals Quick Release Pedals Cycling Platform Pedal with Pedal Extender Adapter 5 These pedals are great, you wont regret it. Ja*** I bought these to use on my ebike, they are great in every aspect, i even had a fall with my bike at around 15mph and the pedal took some damage which it still works perfectly, one reason i mention that is someone else reviewed theirs's stopped working after they crashed. The main reason i bought this was to add extra security along with a bike lock (i use the skunklock which is great and bulky), that way if a theif is eyeing your bike, they see no pedals thus they cant pedal away, and especially a ebike that thing is heavy, they wont get very far, especially if u have a bike security system to alert you if someone is messing with it, this will work in tandem greatly. plus rarely do people drive around in their trucks to steal bikes, its more people staking out certain bike area's. i recommend buying this even just for storage aswell, if u got a slim spot, and you use foldable handle bars and these, its great space saving. hope this helps anyone!

KAC Bike Rack for Car, SUV, Hatchback Mount - 2" Anti-Wobble Rachet Hitch for 4 Bikes - Heavy Duty Bicycle Carrier, Easy to Assemble/Install - Tire & Frame Stramps Included 5 Great bike rack! HM*** Love this bike rack! It locks in the hitch and all the hooks lock down on the bikes so no need for an additional bike lock. We got the four place one so we have the ability to haul our friends bikes when they go with us but we can easily remove the attachment which converts this from a four place to a two place bike rack. It seems heavy duty and secure. We took a long trip with four bikes and couldn’t even tell they were behind our car. The hitch has a feature that locks it in place so it doesn’t shake and make a bunch of noise going down the road. We had a four place Thule rack that did not have all the features this one offers and made a bunch of noise while going down the road, even if we didn’t have bikes on it! So thankful we found this one!! B07QHZPSVN US

Eclipse U220 Bicycle U-Lock - U220 4 Flexible, secure lock that comes with a bit of weight Vi*** After a lot of research, I have picked this lock because of it's Sold Gold Secure rating; making it one of the most secure bike locks available according to experts. This means you can rely on the lock if you know how to use it. It is big and wide enough to lock my front wheel + bike frame from almost every angle, which makes it flexible enough to use. It is a heavy duty lock, so you need to keep in mind that this extra security comes with an extra weight to the lock. But apparently this is still considered light in its class. I use it in my backpack, but Seatylock (the brand behind this lock), also sells a holder to attach it to your bike frame while riding. Overall I am happy, but be prepared for some weight of the lock.

Kryptonite KryptoFlex Bike Lock Cable, 2FT/6FT Long 15mm Thick Heavy Duty Braided Steel Cable Anti-Theft Security Lock for Ou 5 Colorado Bison spare security Amazon C*** Now I must say I have no idea if this will keep a scumbag from stealing it or not but I put this around the tire and rim that's mounted in the bed of my Colorado Bison. You have to turn a T handle to remove the tire and this prevents it from turning. Just what I wanted(no slack). It feels very secure and I suppose if nothing else it provides more of a deterrent than nothing at all. B084ZZ6P4M US

Kryptonite 14mm Steel Chain Bike Lock 3.28ft Long with Keys, Disc Lock 15mm Shackle and 10mm x 7ft Braided Steel Security Cable 1 Super stout... then it jammed and Kryptonite went completely silent; over priced Aasi*** I had this lock for a few months (less than a year), and it worked great. It's probably overkill for Dallas, TX but I had an expensive eBike so wanted sufficient insurance included to cover the cost of the bike (which meant going up to this level of lock). What I didn't anticipate is that after a little bit of rain, the lock started jamming up. I tried cleaning it out, but it's still very sticky -- which means I can't really use it (because I might get completely stuck where I can't get it off). So I reached out to Kryptonite... I submitted a ticket... silence. It's been over 2 weeks, and still haven't gotten any response. Of course they have no phone number listed to actually address this, so it's literally just sit and wait... hope my bike isn't stolen in the mean time. B098SCP47X US

Columba 20 inch Folding Bike Bag Matte Black 1 Ripped wide open on first use B. *** As others commented, this bag ripped wide open on first use. As a result I lost the keys to my lock somewhere over the Atlantic ocean so now I have a useless bike lock. There is also no padding- I wrapped my bike in a blanket. But the main problem is it's just very poorly constructed seams (fabric is quite heavyweight). I had no problem getting the bike in once I took handlebars and seat off; I don't understand others' comments about the fit being tight. I also used bungee cords to keep bike pieces tight and together. With that, it was easy to get in the bag- in fact, I think the bag was far too big for the bike and that's one of the reasons it ripped with so much extra give around the sides. Don't buy this, you'd be far better off with cardboard or even a clear furniture plastic bag in my opinion. B09MJN999X US

TiGr Mini+ Lightweight Bike Lock – High Security 8 x 4" Flexible High-Carbon Steel Shackle – Bolt Cutter, Crowbar & Hacksaw R 5 Very strong lightweight portable bike lock! Love it! Rod*** I ordered this bike lock for my bike and it has been excellent. The quality of the lock is top tier and it is quite strong. I have no worries of someone breaking this lock. The size of the lock is actually pretty small considering it locks me wheel and also goes through the frame. The lock itself is light enough to carry in a backpack with my other things. Using the lock was very straight forward as it came with a key that unlocks it and you just place the lock around your frame and wheel to secure it to whatever you have available. I take mine to the beach, so I was able to secure it to the boardwalk fencing without any issues. Highly recommend!
