Im looking to possibly do a 4-stroke build, Id like to go faster than a little 49cc 2 stroke will take me. But before i go for a big engine, id like to get a bike thats more than capable of supporting the engine, me and anything that I throw in my cargo rack. (Ive got a nice cargo rack on my dying road bike). Id say that I have a $200 limit (broke college student) for the bike itself. Any suggerstions? I really like the schwinn point beach 26 but idk if that would be able to hold up to the speeds I HOPE to achieve lol.
