Where can I rent a halfway-decent (or maybe even good) mountain bike for the few weeks I'm in Kunming? Years ago Xiong Brothers used to rent some but I don't know if they still do...

I'll be arriving in KM on 8th February just before the New Year and would like to rent for about a month.

Used to live in KM but have been away for awhile, a bit out of touch. I am on a bit of a budget.

Thanks!

Xiong Bros is the only place I know of with rentals, but they're not that well looked after.
