well depends on your size and build like others have said. but personally i think mods have less maintenence because the drive chain is less hasel like u have a hanger sometimes gears, but on a mod u can just be freewheel chain cog simple unless your going cassette the maybe but personaly yer mod is easyer. if your tall longer bikes you suit your build and you could throw it round more but if your small go for short bikes with good room near the stem so u dont bash you caps up ..haha:D so yer personally mods Thanks bennyb
