That MTB frame should work no problems. Front tube may be slightly thick but easily compensated. I assume your going with a Happy Time? (Chinese 2 stroke frame mount)
Hi Eljefino. Welcome to MBc! Home of many answers, and awaiting your ideas. Were here for each other! Enjoy!
Like Large above, with the boost bottle I can putt along about 2 mph.
Hello and welcome to MBc!
in my opinion, the main tube is too thick, my suggestion is to go to garage sales and make a stronger better bike, i will attach 2 thumb nails of beach cruzin, my hubby with his 26" roadmaster with a thatsdax 70cc, he maybe spent 50.00 on paint and the bike and me with 26" huffy style... a ch80 cc here is a link that i found with great difficulty, as this post kept erasing... http://www.motoredbikes.com/showthread.php?t=7213 some where it says not to drill thru the frame...it will break as these things.. they vibrate, allot! well good luck and happy motoring! my next build will be one of these: http://www.bikeengines.com/ the tanaka 32 2 stroke...
