Customer Reviews

Solid Lock
This lock will definitely keep your bike safe. Don't be fooled by the name "Mini DT" because this thing is solid. To give you an idea, I weighed components:

U-lock - 2 lbs 5 oz.
Cable - 11 oz.
Combined - 3 lbs.

Dimensions of the U-lock:
Width - 6 in.
Height - 7.8 in.
Diameter of thickest part - 1.75 in.

Length of cable - 46 in.

The frame mount is pretty good (easy to install, you'll need a hex wrench though) and it comes with 5 keys (seems like overkill, but whatever.)

For the price and the free shipping, its a no brainer.

Get it and be done with it.

Better than Kr*ptonite!
I would suggest before buying an OnGuard lock, visit the manufacturers website for security ratings. This specific u-lock is rated 4+ out of 5+. It has what OnGuard calls 4x power quattro locking system which provides greater pull apart resistance than their 2x system. The cable is there to allow you to secure additional items such as your seat/wheels. Before doing some research I was simply going to buy a large u-lock, but after reading, it seems the mini u-locks are more secure in the sense that they leave less room for a pry bar or jack attack. They also have the additional benefit of being lighter!

solid lock
-comes with extra security cable
-includes 1 year free theft coverage on your bike when secured using the lock (altho if you read the fine print, it's redeemable only if the u-lock is actually broken apart and you can show that)
-nice set of keys, including one with a light
-nice finish on the lock
-the keyhole is weather-protected (the shinier middle part rotates to cover it)
-snug secure fit (tho make sure it's big enough for your locking situations)

I'd recommend this lock for anything up to medium-high level of security.
