Hey Jaya, First of all you have to take small road trips around your place where you stay ... Blog it in an attractive way ... learn photography ... use the social media platforms in an effective way ... try to showcase and advertise yourself and be the best in business ... things will come your way ... there is no fixed or a written protocol like if you do this you will get sponsors .... try all the ways possible .. Do a lot of try and error methods ... ask your own friends to crowd fund you, try saving money yourself and earn a lot with whatever you are doing ... start small, if you are worth it, things will come your way for sure .... Happy Travelling Bro!!!
Very good question. A simple way to tell is to go ask for it. But I know how tough it is to get sponsorship for long bike rides.
First of all, start off by adding some amount from your own pocket. Then try to talk to the manager of the showroom from where you got your to bike. If he agrees, then awesome. You can try in other places where there is importance for biking like biking stores that sell gears, or any cafe which is exclusively for bikers. If you have god contacts or if any of your friends have, then I think you will be able to get sponsorship. All the best. Ride safe.
