Been in Tokyo for years but just getting into biking again. Live near the Tama River and thinking I want a good bike for trips to Okutama, Mt. Fuji etc. and being a former offroad MTB rider do not know if I should get a road bike or a hybrid. I'm 83kg and although I think road bikes look nicer, I don't know if they will hold up carrying me over all the dumps and stuff around. I have an old MTB with me but the MTB tires make riding such an effort. Don't know if there is a big comfort difference between the two either. Lastly, any tips on how to get a cheap used bike would be much appreciated.
