ABUS is well known for making bike security locks. In fact, their keyed-alike locks work with both bike locks and e-bike batteries with the same keys. This is handled by a key code to match the keys and makes ordering extra keys easy, or matching multiple locks to the same key.

Their new BORDO Big 6000 folding lock is 30 cm longer than the original Bordo 6000, allowing for multiple bikes to be secured to a pole or bike rack with a fairly small size when folded. It features a pick-resistant disc cylinder and 5mm thick, hardened steel bars connected with special rivets. The bars are coated with a two-component compound that prevents the lock from damaging the paintwork on your bike.

It’s not cheap, at $199.99, but it’s very portable and easy to carry, and good peace of mind for your e-bike.
