Can I take a Rapido (Bike Taxi) from Siliguri to Darjeeling?

Hi everyone, I’m visiting Darjeeling next month but I have a major issue: severe nausea from diesel/CNG fumes. I can’t travel in taxis or buses at all. ​I see Rapido shows a fare of around ₹750 for a bike from Siliguri to Darjeeling. My question is: Do the captains actually agree to go that far, or will they refuse once they see the destination? I’m also open to doing a break journey (Siliguri -> Kurseong -> Darjeeling). Has anyone actually done this on a bike taxi? Any advice would be huge. Thanks!
