I am looking to rent a bike in Xining from 5-8. September for some riding in extension of a business trip to Qinghai. Two wheeler is preferred, but a sidecar is definately also interesting (will return to Qinghai from Beijing on my sidecar next year).

Does anyone know where I could rent a bike in Xining for the above days? I have my Chinese MC-license with me, of course :-)
