Hello hello. I'm looking to upgrade my bike for easy transportation around town without having to buy a moped. Coming across an article in MAKE was a stroke of universal helpfulness. Anyway, I want to buy a reliable kit, somewhere in the price range of less than $200, no more than $250. I need something relatively easy and straightforward. My first kit to look at was this one: Included Items Seemed good, would cost a little over $200. I wanted to know if there was something cheaper. I found these: Silver Slant 80cc 2 Stroke Bicycle Motor - Silver Slant 80cc 2 Stroke Bicycle Engine Kit - 66cc Bicycle Engine Kit GRUBEE SkyHawk GT5 66cc/80cc Slant Head Bike Motor Kit (Standard Finish) I would probably go for the second one. It seemed better, but I don't know why. I tried going through the forums to see if someone else had gone through this, gave up, and am posting this. So, what I would like to know is this: Are those kits good? Which is better? Is there somthing I missed? Can someone help me? For a first time motor bike creator, is there a better kit? and what am I really getting into?
