Is it easy to ride a bike from Mohe to Mangui and finally to Mohe?

From Mohe to Mangui by bike, this section is more than 200 kilometers long and takes about 3 hours by car. But cycling will be very hard, especially in this season, when the weather is changeable. The road from Mangui to Mohe is rugged. Inner Mongolia is a county road with asphalt pavement, and more than 80 kilometers of Heilongjiang is a newly paved cement pavement, which is not bad.
