How long does it take to travel around Erhai Lake by bike?

It depends on one's physical condition and whether there are any accidents on the road. Around Erhai Lake is about130km. I went riding Erhai Lake some time ago. The owner of the bicycle rental said to leave the ancient city at 8 am, walk clockwise, arrive at Shuanglang at noon 12, and return to the ancient city at 5 or 6 pm. Later, when my friend and I rode around Er 'an by bike, we arrived at Shuanglang on time at noon 12, but around 4 pm, my friend's car had a flat tire, so we had to push the cart to find a place to mend it. At about 5 o'clock, we had dinner and repaired the tire. Because of the rain, I don't take the line around the sea, but take the Dali line directly and return to the ancient city. I will arrive at 8 pm. If there is no accident, it is ok for boys to return at six or seven in the afternoon, and girls with good physical strength can also return to the ancient city at eight or nine.
