This is how I often lock up my Mobic, especially in high-risk areas such as downtown Sacramento. with one lock, I can protect the entire bike, it's not something that would be a quick getaway, and it just looks confusing. it probably took an extra 10 seconds to partially fold the bike and then another 10 when I was unfolding it.
Now, it might not be a Brompton but my Mobic certainly holds her own!
