Many thanks dear mcmoose for your answer
I think it weighs around 10-15 kilograms, and i am sure about that the frame is aluminium and most of its main and important components have Shimano name on them, but i can't see their exact model. By the way I've seen people in websites and forums say that shimano has good and bad quality components and I am aware of that the possibility of their being not good ones is more.
Also I know what I said was a very little info, but regarding them is the bike worth buying?
The point of my buying a bike is that i have to pay around 10 $ every day for taxi to take me to college and back to home. Also my weight is 123 kg and i am trying to burn some calories and lose some weight using the bike. I forgot to ask: will my weight(123 kg) matter?
I can order bike and its components via shipping companies from amazon but summing the price with shipping rates will cost me multiple times of its price, for example my budget is 300~350$ and I wanted to buy this: Amazon.com : Vilano Performance 700C-21 Speed Shimano Hybrid Flat Bar Commuter Road Bike : Sports & Outdoors
but the shipping company said it will cost me 750$ ! so bike parts will also cost more
My only chance is to buy it from Germany, I have a friend there that can buy it for me and send it via a low cost shipping method that takes too much time , because it is a one time buying and i can not order any parts or accessories in future,so can i buy it and in future if any part of brakes or tires or even chain break, can i use the parts that available here? will they fit if they are the same size but not the same company or mark?
And about choosing the right bike between those that available in Germany, I want a fitness hybrid, can you please help me choose one:
as i said my budget is 300~350$ (280 euro) and i found this models in German amazon that fits my budget:
28" KCP CROSSRAD FITNESSBIKE FAHRRAD STRADALE 1.0 ALU 21 Gang Shimano weiss - 71,1 cm (28 Zoll): Amazon.de: Sport & Freizeit
what do you think about it? Can you please suggest any other models available in Germany?
Sorry for asking a lot of questions, i am really confused
