As of yet, like most other Indians, I've only ridden a single speed, which was brought for 4000 rupees, about 13 years ago.. Yes, it's still in use!
My budget now is strictly 13000 INR for the bicycle (since other things like fenders, pannier will add to the cost). I live in Kolkata (the roads aren't great here), and the bike will be shared between me and my dad. He will be using it for commute (about 10 kilometres one way), six days a week. I'm planning on using it for relatively longer rides (70-80 kilometres), half of it at one go, maybe an hour or two worth of a break and then back. I guessed a hybrid would be the best option for it.. The need is reliability, longevity and cheap maintenance.
Through my "research" (I'm a noob, as you may already understand) I zero'd in on Mach City Munich 21 speed. When I called multiple shops to enquire about its availability, I was told that it's not available currently (would take about two weeks still, if at all). I was also suggested that Montra Downtown is a good option.
Now, Downtown has disc brakes. I'm not sure, but the far I know, they just get the wheel coming to a rather sudden stop, and are also harder and more expensive to maintain. Aren't they?
Both have the same shifters and break levers (three finger) Shimano EZY- fire EF-51, but downtown has Shimano TY300 rear derailleur (TZ40 for Munich) and Montra has TZ500 front derailleur with no mention of what the front derailleur on Munich is. Munich has a steel body whilst Downtown has an alloy body (6061).
What I also want to ask is, say, I get the Munich itself, is it a good idea to swap components before I begin? I've never ridden a geared bicycle before! Or should I just simply get it as is at first and then after I learn a little, then swap, if at all? The rear derailleur on Munich is TZ40, and TX-35 is available online for 899 rupees (Amazon). Different websites told me that TX series is better than TZ series, hence the question.
Please suggest what to do! And also if anyone has any other bike they'd suggest I buy! (please also tell me how I'd be able to find the other bikes and also the reliability of the customer support). I'm not sure if I should be buying online either, I've read various reviews that talk about how much more they've had to spend because of multiple problems with the bike (broken rims, problems with the cassette, derailleur, etc).
I'm also unsure whether triple chain rings are a good idea and would like to know if I should swap them out for something else or if I should just get a bike that's got a single chainring.
Thank you in advance!
