Top Reddit reviews mentioning Bike U-Locks:

Kryptonite Evolution Mini-7 Bicycle U-Lock w/ 4’ KryptoFlex Double Loop Cable https://www.amazon.com/dp/B005YPK9VQ/ref=cm_sw_r_cp_api_glt_fabc_P9QPVYC9E0EV23KY9MA0

This is a good option. Basically you want a good U lock for the frame and a cable for your wheels. Kryptonite is one of the best bike lock manufacturers.

Get a good lock. Forget about cable locks they are rubbish.
https://www.amazon.co.uk/Kryptonite-Evolution-Lock-Frame-Bracket/dp/B005YPK9C0/ref=pd_sbs_200_47?_encoding=UTF8&pd_rd_i=B005YPK9C0&pd_rd_r=1367c1ca-40d1-11e9-8014-95dfc10cc171&pd_rd_w=QmGDx&pd_rd_wg=K8xfh&pf_rd_p=18edf98b-139a-...

Yep, I'll second the Kryptonite- best lock I've ever had, and have not had a bike stolen since I got it 4 years ago.

I got the Fahgettaboudit- worth ,imho, everysingle dollar I spent on it.

If you buy "cheap", chances are that you're either buying something that's built to be a temporary toy or buying stolen (thus increasing demand for stolen bikes). What you need to do is ask, "Where can I get the cheapest price for an unstolen bike that will last me four years?"

The ASUCD Bike Barn's Aggie Bike Buy option is an incredibly good deal that few bike shops can match. https://asucd-bikebuy.ucdavis.edu/product-category/bikes/ The guy who runs the shop (Robert) is ultra-sensitive about the cost of bikes but since he and his team has to fix the bikes, he's always looking for the best value. An 8-speed Biria ($475) will be enough bike for most riders. Coupled with their 4-year unlimited labor plan ($175), you will have a bike that will work well for 4 years. (Just make sure to put the plan to use! If something doesn't feel or sound right, take your bike in for a check-up!)

But you also have to keep that bike secure, so you NEED to purchase at LEAST one great lock and at LEAST an supplemental cable. My favorite setup is the Kryptonite Evo4 standard size U-lock and cable. https://www.amazon.com/Kryptonite-2079-Evolution-Bicycle-KryptoFlex/dp/B06XZT8KZ1/ It comes with an anti-theft guarantee of $1,500 (as long as you register the lock, use it correctly, and file a police report if the bike is stolen)!

That's probably more money than you want to spend, right? $475+$175+$60 = $710 (plus tax). But that will get you:

A non-stolen bike you want to ride, will be rideable for 4+ years, and that will likely not be stolen (if you actually use the lock correctly). If you purchase a "cheap bike" (Walmart, Target, Costco, Big5, etc.), you'd be lucky if it lasts the year. And if your bike doesn't work, then you've just wasted your money.

I am using this Kryptonite Evolution Ulock with Cable. It is pretty sturdy and comes with a mounting bracket, and because of the included cable you can lock your front wheel along with your frame. It has a year warrenty you can sign up for free theft insurance, if the lock gets cut and your bike gets stolen you can get 2.5k coverage.

Hey there! :) Sorry I am late with my response- any luck yet? Have you found ye olde scooter boi?

I am still rocking my hiboy even tho i crashed it- and I got that dreaded "02" error cries in needs a new motherboard

As for locks, so far so good I have been lucky in that no one has harassed me for my scooter, I am using one of [https://www.amazon.com/Bike-Lock-Cable-Mounting-Mountain/dp/B01KD9AQ92/ref=psdc_194613011_t2_B07GV9862G] and so far i have been lucky no one has attempted to take it. I am usually only gone <5 minues enough time to run in the 711, get my energy drink in 60 seconds, then wait 4 minutes for the slow ass cashier to ring me up LMAO but yeah I think it is just pure luck a scumbag was nearby, MOST people are honest.

But yeah ignore my early AM ramblings, let me know whats up!!

peace, 7w21

I got

Kryptonite Evolution Mini-7 Lock with Flex Cable and Bracket - Orange, 7-Inch https://smile.amazon.co.uk/dp/B06XZT8KZ1/ref=cm_sw_r_cp_api_fabc_XHFcGb6W6MTXD?_encoding=UTF8&psc=1

I wouldn’t leave it overnight but after watching a lot of lockpick lawyer and balancing size / weight/cost for runs into a shop (especially during the day or locked up at the railings up front) I feel this is a good balance. There’s a chunkier version if you want something thicker but I don’t see someone taking an angle grinder to a lock right at a store entrance.

The mini 5 won’t fit most scooters. This one is small enough to prevent going over the deck.

Make sure you have a look at how to lock with a u lock.

Hope that helps!

I purchased this one from Amazon, I've only needed to use it a couple of times but it has some really solid reviews.

Not much you can do now, and I don't think the police will be very interested because it has very little chance to amount to a conviction.

For future reference and as a PSA, this locking technique has never failed me (with a Kryptonite cable for the front wheel, cf. amazon): https://www.sheldonbrown.com/lock-strategy.html

I avoid the problem by buying a U-lock that's beefier than the bike itself.

I've been having good results with the Kryptonite New York Standard bike lock. It's a little pricy, but I have a nice bike, so it was worth the piece of mind to me. It's also very well reviewed and even endorsed by the Lock Picking Lawyer on YouTube.

I wouldn't be too scared of CL. Send a few emails back and forth and gauge the person, then make an educated decision whether to meet up in a public place.

I would recommend looking for an 1980s Japanese steel bike. Steel is heavier, but it absorbs the bumpy SF roads much better. Plus, it's cheaper and there ought to be a larger selection in your price range. And looking outside SF only increases your selection.

I also assume you would want a road bike.

Some "good" frames are the Tange #1 and Tange #2 (Tange #1 being better by a little bit). If you find a decent quality bike with a #2 frame for ~$200 and a #1 for $300, it's a good buy (prices are higher in the Bay Area, bikes are no exception). Some example models with those frames are:

Bridgestone RB-1 (#1ish)
Bridgestone RB-2 (#2ish)
Centurion Ironman (#1)
Centurion LeMans (#2)
Nishiki Triathlon (#1)
Nishiki Prestige (#2)
Miyata 600 to 1400 + Cross/Pro/Team (higher # is better)

As for components, top of the line (for that era) were Shimano 105, followed by the slightly older Shimano 600 or Shimano Ultegra. Sorry, I don't know much about other brands :(

Those are just suggestions. It's more important to get the right fit for your bike though!

As for a lock, I recommend the Kryptonite Evolution Mini-5.

Good luck!

If you have a bike on campus, and this post is scaring you, get a better lock and learn how to use it. So many bikes I see around campus/town are secured with simple cable locks that you can cut with a decent pair of scissors.

Get a D-Lock with cable (example), lock up through your frame and rear wheel to a proper bike rack (not a street sign) and use the cable to secure your front wheel.

Not saying OP did anything wrong, I don't know how they parked it. But bike theft is a crime of opportunity, and I see a LOT of opportunities.

Kryptonite Evolution7

Have one, recommend it. £37 though.

Kryptonite's locks are made in China and in Taiwan: https://thebestbikelock.com/best-bike-lock/abus-vs-kryptonite-vs-onguard

Also, read the several reviews of Kryptonite New York of the lock being cut by thieves (with pictures): https://www.amazon.com/Kryptonite-New-York-Standard-Lock/dp/B06XCH21YH

I picked up a scooter my last semester because I had to go from architecture building to west campus for back to back classes. It was super convenient and I found it worth not having to fight to get on the bus. I used this lock whenever I secured the scooter.

around the frame behind the front wheel.

really sucks you can't take it in with you.

https://www.amazon.com/Kryptonite-New-U-York-Heavy-Bicycle/dp/B06XN5GV9K

That will keep honest people honest and buy you a minute or two with the rest. I doubt you can do significantly better lock wise.

I would also hidden install a cellular/GPS tracker so you have some chance of recovery

Why are you locking through the wheel? You use a smaller but thick u-lock like this around the neck. I even think that lock in the picture is a bit too big and would go with the Mini I linked.

I got a steal.. brand new delivered from ebay for 65

( this is the lock I have and would get if I were you. Only had one theft attempt I’m aware of. I was doing Uber eats and had the bike in my view outside but left unlocked. I wasn’t locking my bike at the time because my bottom bracket was broken so my pedals were strapped together parallel lmao. I figured no one would want to steal it because they couldn’t even pedal. I suppose it worked. The guy that parked his bike next to me wasn’t as lucky 🙃.

Even since then I don’t lock my bike as much as I should 😅 It’s usually ~20ft. away from me and in my line of sight or I’m just running in and out of an apt. Bldg to make a drop off. I plan on getting air tags as well just in case)

I also have this u-lock for quick in-and-outs, and to lock my back wheel when I’m going to be away from my bike for awhile

I have a couple of these that I’ve used regularly for my bicycles:

But so far I’ve been able to take my scooter everywhere I go. I’m less concerned about it being stolen than being vandalized. People are really weird about electric scooters. I don’t feel comfortable leaving it out of sight.

I haven't had any problems. Use a U-lock like one of the kryptonite ones, make sure it's around your front wheel and frame. This is how I lock it most the time.

If you intend to keep it out in public for more than like an hour, I'd also maybe get a wire + u-lock. Something like this. You lock the front-wheel and frame and then the wire goes to the back wheel.

Also bring the bike into your apartment and don't lock it up outside.

TBH, if I'm gonna be out for a long period of time, I won't use the bike. I use the bike mostly for errands.

Really it's all just a time and numbers thing. If you leave a bike out in some apartment complex garage or on the street....given enough time someone can break into it. Like there have been videos of people with full...mechanical saws breaking locks. Nothing is truly un-breakable.
