Hi guys, I'm new to motorized bicycles. I just bought a 49cc 4 stroke engine kit that is 2.5 horsepower. I weigh 203 pounds the engine is great going on flats but struggles on slight hills. So I'm going to upgrade. There are 2 harbor freight engines. 79cc 3 horsepower and 212cc 6.5 horsepower. Will the 79cc engine pull me up hills? My thoughts are what can a extra half horsepower do? Going from 2.5 horsepower to 3 horsepower doesn't seem like much of an upgrade. Help..... also I put a picture of my bike. Will the 212cc or 79cc engines even fit on my bike?
