Couple of months back I was also in same situation. You can read my discussion on below link:
Long story short: I bought merida crossway in 25k but that was last year model so I got discount on that. you can still get the 2015 model in 27-28k.
Schwinn sporterra sport: It does not have any suspension but it is super light and you can get it in 20k. Perfect bike if you don't need suspension.
Schwinn searcher: This one is with suspension. you can get it in 25k.
Btwin riverside: You can have a test ride in any Decathlon store and you can get it in 20-25k range.
Scott: It will cost you around 30-32k. The only thing I don't like about this cycle is its ugly seat.
Trek: the brand is good but I don't have any experience on any of its hybrid.
Don't go for firefox, schnell etc. They may feel same during test ride but the ride quality may deteriorate in the long run. I had test ride of rapide 21s but I felt it heavy. Still if your budget is limited, prefer montra over firefox.
check out btwin riverside 3, its a good bike.
Go for "Btwin Riverside 3 Trekking Bike" from Decathlon, Thane @Rs22,000/-. This is the best hybrid bike available in India at that price and features. It will give you a long trouble-free life, and you will not regret your decision.
Select size according to your height as per chart available in Decathlon website.
The Decathlon online store only shows Btwin Riverside 3 for men. Is there a difference between that and the Btwin Riverside 3 'Trekking Bike'? I can see that the price you have mentioned here (22K INR) is quite less than that mentioned for the bike in the Decathlon online store (around 34K INR).
From your posts in other threads, I found out that even you own a Riverside 3. Could you please tell, which one do you own? I am presently in a dilemma to buy a hybrid myself. Having a budget of 20K INR, I have been researching a lot about bicycles in this range.
Although, understanding from some helpful post from experienced people like yourself, Aaron and others, I follow that only researching in the internet won't help as I should also go to the store and check the bike(s) to suit my comfort; I am still one month shy to be able to go to a Decathlon store myself. However, during this one month, I want to be able to make up my mind to choose at least 2 bikes in my budget range.
I am 5'11" tall & weigh 87 kg. I wish to use the bike for commuting. The average daily usage per day will be 30-40 km, and during weekends 60-70 km.
Could you give me some suggestions?
