I will be traveling to pune by bus from bangalore and i want to know how to go to Mumbai from pune on bike.
Are there any bike rentals which offers a bike for rent from pune to Mumbai for one way ?
Yes there are lots of bike rentals in Pune. And the ride is pretty decent as well. However, most rental places would not agree to picking the bike up from Mumbai. Even if they do, you'll have to pay quite a bit more for the pickup. It makes more sense to ride back the next day. That way, you will have the time to explore Mumbai on the bike for a bit as well.
Even googling bike rentals in Pune will give you a lot of options for renting bikes. Lots of local mechanics also rent out bikes at much cheaper rates, but they are not always well-maintained.
