In addtion to buying these i will put on a pannier on the front and replace the handlebars with butterfly bars. These three bikes are hybrid style.. have lower back problems so i want to stay away from road bikes and drop bars.I am not pushes about time and am only planning on cycling around 70km a day for 6 days a week. i am planning on doing this rate in an uprigth body position rather than been bent forward on the drops as this could hurt my back.
I will be cycling on all sorts of roads including the pamir highway so I will need 40mm tyres. i wont be carrying too much gear either.
could someone please help me on a bike to pick? Will any of these three bikes do the job? Im not fussed about gears or brakes really as long as they work im happy
Of those three, my personal bias against cheap shock forks means that if I were picking the three for myself (and my needs), that Stevens is the one I'd pick. That being said, you are planning a rather long trip and will undoubtedly encounter less than ideal surfaces, so the Cube might be an option (plus it has better FD/RD and 9spd cassette). If you pick the Cube, I would suggest you upgrade to some full coverage fenders ASAP, because the stock ones are more fashion than function.
BTW, just because a bike has drop bars does not mean that it has to be set up where your nose is level with the twig and berries- it depends on the geometry.
Welcome to BF! There will probably be as many different answers to your questions are there people who provide answers. If I was going on an epic tour like what you described, I’d want to do it on a bike that was designed and built for long distance, self-contained, fully loaded, “all conditions” type touring. I don’t think I’d try it on a city bike. But... I’d suggest you spend a lot of time doing product research, a lot of info gathering and window shopping at LBS's as well as a lot of time scouring touring forums before choosing your bike. Good luck with your quest and good luck with the lifetime dream tour.
