Indiacar.com has the info on Two wheeler too.
Let me tell you, One situation where it is useful ... I want to buy a two wheeler 3 months ago, I start searching for which is the best vehicle, then I ended up with Mouthshut.Com , but it is not enough for me.. I want technically proven best vehicle as I am a technical guy.
So one day I found this site with different name Indiabike, really I was thrilled to see the info it has in it.
There are Technical reviews on different vehicles(2 wheelers) posted by Indiacar.com and links to other sites like over-drive, which are very useful before buying the vehicle ... simply you will become expert in one day among the available vehicles in the respective segments(like 100 cc, 150 cc..etc).
Best part of it is, Road Test by Dileep Bam, he is a bike expert in recent days with passion to ride and test all kinds of vehicles.
Last but not least, you can post questions to experts, and it get replied with in 1 week. When I have doubt in my mind which one I have to buy between Pulsar and Fiero... I settled with Fiero F2 after got reply from Bam with comparisons.
So why are you waiting for ... go and Browse .. if you are serious about the Bikes...
