OnGuard Bulldog MINI TC 5013TC Bicycle U-Lock

Perfect size for the Sheldon Brown technique. Better mechanism than more expensive Kryptonites. Perfect!

Several aspects of the Bulldog MINI U-Lock make it a very good choice for the commuter in areas where moderate security is adequate. First, the lock is compact, easy to transport in most types of bike-mounted bags or packs, or on the frame mount (not used by this reviewer). The compact size is just right for a single point connection of a frame component to a heavy duty 'U' rack or a parking meter. It won't fit around the trunks of even small street trees - this is not usually a problem, since street signs and other urban elements offer plenty of casual anchorage points in most areas when bike racks are missing or full. Second, the lock is light-weight by U-lock standards, so it won't feel like a ship's anchor in your bike bag or on the mount. Third, the plastic finish coat and end caps are easy on your bike. And fourth, the five keys including a lighted key that are provided with the lock offer more lost or spare key convenience than is probably warranted.

In all, a solid, economical choice.

The newer Bulldog MINI is distinguished by TWO yellow end caps and a different mounting bracket using a metal piece on the U-lock. Apart from the bracket, OnGuard claims the difference is mostly cosmetic, but OnGuard also indicates that the anti-theft insurance and guarantee terms differ between these versions. Moreover, OnGuard flatly states that the newer version of the Bulldog MINI is the one that should be purchased if this model is desired. If/when this seller distributes the new version, the photo should be changed. Note that the new Bulldog MINI list price is $35 list price, and that is the price for which it is sold at local recreational equipment stores. So paying that much (w/ shipping) for an older version might not be the best deal.

It's been only two weeks, the lock became stuck and I can't unlock it. This is the first time I buy a product from the brand, I'm really upset.


The warranty department sent me a new one after one call. Thanks to that. I wish that it won't stuck easily like the last one.

After removing the ugly yellow plastic pieces, this lock was perfect. It's small enough to fit into your back pocket (depending on your jeans) and big enough to lock to most bike racks. I like that the key stays in and won't fall out until it's locked.
