Abus Ultra 410 U-Lock - 3.9 x 9", Keyed, Black/Green, Includes Cobra cable

Seems solid and sufficient on its own for quick stops and short term protection in medium risk environments. Weight is reasonable for a lock this size. Minor gripe is sometimes have to fiddle a bit to release shackles. I bought the 11 inch version very reasonable price. The extra length of the U- lock allows me to lock the front wheel to the frame of my bike. I have an Aventon e-bike and the frame is thicker than a standard bike and a typical 9 inch U-lock won't accommodate it. This should also allow me more options to lock my back wheel and frame to a variety of posts. Beware the 11 inch size may be challenging to mount to bike frame for storage.;

This mounted well to my inexpensive mountain bike. I assume this style can be broken by pros (anything can really) but I just wanted to stop simple theft. Pleased with purchase;

Para unir bicicletas. Ojo que el arco de U es normal. No es el largo. Pero este es más fuerte.;

I use this lock and at least 3 additional locks to secure my radwagon 4. My goal is to make a potential thief have to work so hard to get my bike and really increase the odds of getting caught as my deterrent. This lock is about the right size with the child rails to reach a stationary object and secure the frame without leaving too much play. The RadWagon 4 has extra wide frame bars tires and guards that make it impossible to include a wheel in the lock up with a u lock. I share this incase you are shopping for the same bike or another big frame bar bike.;

Im ganzen macht das Schloss einen guten Eindruck und passt auch bei einem Ebike mit 225ger Reifen problemlos. Leider ist der Halter zur befestigung etwas unpraktisch. Wird mit gut Glück an einer dicken Sattelstütze passen (32mm) ist zwar ein Adapter bei der es auf ungefähr 27mm reduziert beim Ebike hatte es leider nirgends gepasst somit hab ich mir Unterstützung vom 3D Drucker geholt. Mit TPU Filament ist das echt perfekt und klemmt super.;
