Shanghai Insiders is a motorbike and vintage jeep tours company based in Shanghai. (They used to offer sidecar bike tours, which were awesome, but since summer 2019, sidecars aren't allowed on the roads). They specialize in customized, off-beat tours for small groups, avoiding the big tourist spots. For more info, contact Shanghai Insiders at Book@insidersexperience.com.
