A mountain bike is a variant of the traditional bicycle that has a light but sturdy frame, broad tires, and numerous gears. These characteristics make it designed for off-road cycling, hence the name, and is made to last in difficult and rough terrain.

Security
The number one aspect that you need to look into is the security that the U-lock offers. We recommend researching the security scores of a particular product to ensure that it is strong enough to prevent attacks, which is very important for mountain bike owners.

Portability
Mountain bikes are meant for traveling or cycling in rough terrain; thus, U-locks need to be highly portable and easy to carry around.

Price
Generally, cyclists recommend getting a lock that is at least 10% of the price of your bike. This means that for a $1200 priced bike, it’s ideal to buy a lock that is at least $120. Of course, the price does not dictate all of the other important features, but it does give you an initial idea of the level of quality.
Insurance offers
Most bike lock companies offer insurance programs for bike theft or key loss. If you want to ensure your bike, select a bike lock with a bike theft insurance program and a key protection program. Therefore, in case your bike is stolen, or if you lose your keys, the bike company can reimburse or replace them for you.
