After our garage broken and expensive e-bike was stolen, we wanted to protect our new e-bike better. Looking for a really good lock, I came across this Abus. This castle no one gets so quickly without Flex. Here's why it's extremely difficult. We use for our two wheels the 170 cm version. Also in detail very well done, including an illuminated key. We take the castle while on holiday with the wheels to secure overnight. This castle we can sleep better again.
