Re: Please suggest a best bike for me!

Congratulations on your bike purchase!

One suggestion - whenever tyres of your bike will be up for change (or you can decide it in about 12-15 months from date of purchase) - please go for MRF tyres.
In entry level tyres also, MRF provides relatively much better grip. CEAT has longer life but not as confidence inspiring as MRF. TVS tyres I don't have good experience with.

Also, whether you ride fast or slow in city or highways, please surely use helmet and any other additional protective gear that your budget permits.

Have a nice ride!
