ULAC TRON-XD Fingerprint U-Lock for Bicycle, e-Bike, Scooter, Door Lock, iF Design Award 2019

I love the fact I don't have to fumble for keys with this lock. The one problem I have with it is there is no battery indicator and it appears the battery goes down while not in use since if I plug it in after several days of sitting it starts charging.What would make this lock perfect is if there was some type of always on or on demand battery life indicator. Then you could determine if you need to charge it or not. As it is, I have to guess at the battery level and since I don't want it not to work because of a low battery I'm always have to charge it 'just in case' I might use it. This is inconvenient.Would be much easier to check a battery indicator and opt not to charge it if it didn't need charging instead of having to guess or assume it should be charged to full every single time you go for a ride and think you 'might' use it.

This lock is cool (as far as locks go). Good design. It's a solid lock. Weighty (but not terribly so). If you have fingers, you'll be able to use this easily. Haven't tried, but you could probably use toes if you have no fingers.The only thing is there's no manual or instructions in the box. There's a QR code on the back but when you scan it, it opens up ULAC's Instagram page. However, there's a Vimeo video which helped (there's some vids on YouTube too, but we watched the Vimeo).When you first open the package, the default setting is such that anyone can put their finger on the pad and it'll unlock. You have to set/program the lock then it's good to go. And you also get 2 keys to open it manually. You should fully charge the lock before the 1st use.It works. I know the price is higher than a lot of other locks out there, but if you buy a bike or scooter or anything that you could use this lock for that's worth any money over the amount of free, you should use a quality lock. The price of this lock is most likely going to be less than whatever it is you're trying to protect. That's my thinking anyway. It is a little weighty, but not unmanageable or terrible (fits easily in a backpack or messenger bag or even medium size purse). It feels nice in hand and the silicone like coating protects your bike or scooter or other thing from scratches. No regrets on this one so far!

Works as it should so far. Well made.

I really like this finger print u lock. Unfortunately, it was too short for my needs. I wish they would make a longer version of this lock. It's a great lock if you need a short u lock. I don't understand why they would make it so short. The purpose of a U lock is to hook your bike up to a street post, therefore, it needs to be longer.

The finger print functionality works really well and makes it very simple and easy to use.I haven't researched to see how secure it is compared to an Abus lock - but because it's so easy to use it could be a great backup lockFor my cheaper bike - I use it as my primary lock and so far so good!

I don't know how good the security actually is, but I know it's better than me misplacing keys and then not using a lock at all! The battery life is excellent, unlocking is very simple and quick (you might have to wet your finger slightly, but it's never a huge hassle), and everything seems every sturdy and well-designed.

Just got it 3 days ago. Came very well packed with the USB cable for charging included. I charged it full for 3 hours as instructed before registering my fingerprint. Wasn't hard to set it up, register the fingerprint based on the clear instruction in the owner's manual. It also has the backup keys in case the battery goes low.I wish to have come in a larger size as well.Kim Adams

I got a present for my dad, I did know how small it is when I got it. Would be nice if they have a bigger size
