To give my opinion about this bike.
The bike, although 17 kilograms (it didn't feel heavy to me), is sturdy and comfortable to ride and it is also fantastic in its GRAY-GREEN color.
Let's go for opinions-tips-thoughts (take them as you want) in 5 parts.
1) I got the 50 size even though I weigh 79 kilograms and I am 1.82 meters tall, I raised the saddle a bit and it's great.
2) The gearshift doesn't work well and it needs the TX to be installed or else don't change it immediately and because if you get it assembled, they don't have them adjusted and they put them as they are, do an adjustment and then change the gearshift since it's too early for something like that which works satisfactorily with the adjustment. And also, it takes a few days to get used to changing gears because it's a bit difficult if you're used to gearshifts with the levers.
3) The saddle definitely needs a gel change or a cover, it's not worth it, you know... Oh, and a cover for the handlebars if you want.
4) For long distances, gradually make changes to the cassette, bearings, and the rest that are already written in the comments.
5) The tires could be a little harder if you want to change them.
Note 1: The bike, which for some is heavy, for others is moderate, etc., I have to say that until now, at the age of 50, I have changed many bikes according to my preferences. The weight of it is fine, which if you go from very light to this, it's logical for it to feel heavy (a little, quite, much more) and it will take some time to get used to it, while if you go from a few kilograms less to this 17-kilogram one, you immediately get used to it and it's until you find the right fit. Now, if you're riding a bike for the first time and it's heavy, that changes the matter because normally you should start with lighter ones and then move on to the heavy ones.
Note 2: The changes will be made gradually because I'm not in a hurry.
Note 3: 15-17 kilometers is not considered a long distance and you only go once in a while. Maybe in the summer, 3-4 times a week. That's when you make changes, so you want or rather it's better when it's time to change some things on the bike.
Note 4: A night video with the bike, which is a JEWEL and fantastic with this amazing color and with the lights, you would think it doesn't cost 231 euros (that's how much I got it on sale) and it looks like it's worth much more if you see it for the first time.
