explain a bit more what you mean with riding on the city. just commuting? how much distance aprox? do you think you may probably like it and ride a bit more than just from A to B?
in any case 800 is more than a decent budget.
also: does any type of bikes call you? mtb/hybrids tend to be solid and comfy as fuck, good for cities where roads arent so perfect or you can go up down curbs etc...more road bike will make you go faster but you need more skill to feel safe... im a fan of buying used cause you can get great deals.. but that means you need to know a bit of bikes..no bike friend near?
my personal choice for cities are semi old hardtail mtb's, this means the ones with only front suspension and rigid frame..they can get very light but can take a beating. if you put thin slick tires (1.5" wide is my fav) and they can fly. you could actually even get a 98-2005 old biike like this for cheap, but so old usually have fucked up drivetrains due to use or just cause their old...so try to get something newer..if used..also cjeck that front suspension fork isnt too heavy so the bike is totally unbalanced, that happens quite a bit....again this would be what i would choose. in anycae you truly could spend less than 800 say 500 if you wanted, but if money isnt a prob... also invest in a good lock so it doesnt get stolen. cube has good bickes, no clue on alkhoff, that may be cause im from overseas, some setuff just doesnt get here.>>1101004
yeah, just ride a bit more, its incredible how you will get used to the bike and start controlling it better..just ride more and dont get scared. also dont try shit you dont manage too well in busy roads...but go for it!
