Here is something I do not do in Saigon, lock my motorbike. Unfortunately this is something you have to do in Shanghai and China in general. There are no parking people to watch your ebikes here. I had to buy a strong bike lock from Taobao. I am glad I got it since the lock that came with the bike broke couple days ago.
It can be a pain to lock and unlock my ebike each time. If I had known about Mobike earlier, I would not have bought an ebike.
