Both Lock / Sperre

Both Lock
Both Lock

‘Both Lock’ is a new concept of bike lock system utilizing a seat post.
You put bike’s seat post among spokes between a hub and a rim of the rear wheel,
which will block the movement of the wheel completely.
Install an accessory of fastening a seat post on the bike frame first.
A bike user does not need to carry a heavy lock. Users can solve two problems at once,
one of which is concerned about bike safety and the other is about bike seat safety.
