This is an interesting development. While most users will be Chinese, there are not restrictions that I know of on foreigners using the facility.
The north China city of Tumen, bordering the DPRK (North Korea) has received permission to organise tourist bicycle tours from Tumen into the DPRK.
Young Chinese seem to be interested in NK, perhaps because it gives then some insight as to what China was like in the past.
Chinese city launches bicycle tours to DPRK
(Xinhua) 10:02, May 03, 2014 A border city in northeast China launched Friday bicycle tours to the neighboringDemocratic People's Republic of Korea (DPRK) as tourism to the country booms.
Thirty-five Chinese tourists joined the first self-drive travel by bicycle from Tumen City,Jilin Province, to DPRK's Namyang city, said organizers.
The tourists spent three hours in the DPRK.
The bicycle tour is inexpensive and only needs simple procedures, said an official of theTumen Tourism Bureau. He said the route is expected to attract more tourists to theDPRK.
Excursions by train from Tumen to the DPRK's Chilbosan resumed on Wednesday.The tourist train was launched in April 2012, but was later suspended.
Tumen has highway and railway service to the DPRK.
I've heard that self-drive trips in your own car are also becoming possible. I can only imagine that they may be escorted. Can't quite imagine hundreds of tourists in cars driving all over NK
