Bicycle & E-Bikes: U-lock Video Guide

With a lock like the U-lock there is more security when the cyclist is on the road with his bike. Especially when an expensive bicycle has been purchased, one does not want to experience after a rest that the bicycle has suddenly been stolen. The shackle lock is a lock that will stand out due to its easy operation. However, this does not mean that there is any security restriction to be accepted, as the practical shackle lock must be cracked by the thief with a special tool. And this can only ever be used for one special shackle lock. This provides the best safety for the cyclist and those who use their bike for trips to work can be sure that they do not have to walk home after work. When buying, you should pay attention to the good quality of well-known brand manufacturers, who cost more, but do not compromise on safety. Cheap bargains offer the advantage that they cost little, but then you will quickly notice that such a U-lock does not meet the best security standards

In the variety of safety locks for bicycles, the U-lock can also convince the expert. Where even a bolt cutter fails because a 13 mm parabolic bracket ensures safety, a wheel can calmly arouse the envy of fellow men and interest thieves. Once secured with the shackle lock, it will not leave its secure place and will serve you well for many years to come. The modern thief is, of course, also specialized in the latest methods such as lock picking, but modern padlocks also ward off these attacks on the bike. Even protection against pulling and hitting is provided, so that with a shackle lock a wheel always has a protection that can correspond to the highest security levels. Another advantage can occur if you want to insure your bike, because insurances want the best protection for your bike and so a bike shackle lock can always be recognized by the insurance company. When choosing the right model, the buyer should always look at the length of the lock, because if it is too short, it will be difficult to place the lock around the frame and rear wheel. Only if the placement here succeeds, then the cyclist can be really sure that his expensive bicycle is not stolen.
