Hey Vaibhav, It is not going to be a short answer and my blog is full of such experiences. I have closed the DoW Community forums and in process of repurposing these experiences and articles on All you ever wanted to know about biking trip to the Himalayas. Within July month those all articles will be compiled and published as one detailed guide and video. Till then I will suggest that you refer: If you are a beginner in riding, the best month if September, from second week to the last week (need to manage cold though) or first three weeks of July is also good option.
