I'm new to the game.... I have a raw questions for my fellow enthusiasts. I'm a bigger guy weighing about 265. I have created a 50 cc on an old Murray 3 speed.... I run a 41 tooth sprocket. On a flat surface I have okay speed, but on small and large inclines I have to a bit a pedaling. (a lot of pedaling)..... What can I do different? I plan on doing another build what can I do to build a better bike for me?
