Hi Nick,
I am not sure if openstreet will solve my purpose. What I have in mind is
that when someone is planning a trip , he can enter the route details in
the trip info. This should give the approximate distance etc. ( btw bike =
motorcycle here in India). Also apart from google maps I have not really
come across any mapping service which has a good coverage of roads and
cities in India.

I understand, what you are looking for seems like an application of
geodjango and a classic gis application.
Still using openstreet map will give you access to a lot of information
even if the data are not complete, alternatively you could use tha
google maps api but I am not sure if it is free, and even if it is free
today you have no guarantee that it will be tomorrow.
Speaking about my area, which is a small village in the southern Crete,
Greece, I see that most main roads are mapped in openstreet map.
I have already improved the existing data by adding a few small villages
that where missing, and today
I have added some agricultural roads in the near vicinity. May be your
case is similar.
Anyway here is a tutorial with geodjango and google maps, that may come
close to what you are after
http://invisibleroads.com/tutorials/geodjango-googlemaps-build.html
and some map related django packages
https://www.djangopackages.com/grids/g/maps/
nothing special with the links, you can find a lot more, just by
googling geodjango and maps.
Keep in mind the risk of google changing the license and pricing of
their api (e.g the translation api used to be free of charge, now it has
a price)
Cheers
