Hi, I am new to this forum, so I hope I am posting this in the right section! I've recently moved home and with the move I lost access to a bike shed I was using to keep my bike in. Unfortunately, for a number or reasons, I need to leave my bike outside. I am not on a main road, it's a residential entirely new area that is currently still being built and my house is among the ones that are furthest from the main road. I already have a disc lock and a full cover. I am looking to buy one of either Almax or Pragmasis chains to secure my bike and I'd like some help if possible. At least initially, the bike will be right outside of my main door and it will be chained to a lamp post. Can I ask you which size in mm would you recommend? Should I go for the 19mm or will a lower size be sufficient? Additionally, regarding the ground anchor: should I install it even though my parking space it is not directly outside of my front door (and outside the field of view of my camera)? or will the lamp post suffice? Just as FYI my parking spot is possibly 10 meters from my door on the left hand side, in front of one of my neighbors door (yeah, new houses built weirdly). Thanks and apologies for the long post.
