hello everyone im new to this.. so i wanna start by thanking all for there posts of bikes projects . well i just got a kent siesta from big 5 for $120. im going to install a china girl i just got with fresh new upgrades... so they say lol. its a 26" bike like a cranbook. anybody heard of it? ill try to post pics later. any tips on the build? ive read alot about the chain tentioner not working very good i was thinking about welding it or drilling hole in frame to keep it from coming in on the spokes. any thoughts on that? or should i go without tentioner at all? i wanna get a rear hub adapter from sbp or pirate idk the size i need yet. & i might need the front uni motor mount now. thanks for any help.
