What are some good cruiser frames that are also easiest to build on? Tried searching this question before making a new thread but couldn't seem to find a direct answer. Can only 26" and 29" size frames be used? Which frames are easiest to center the stock back sprocket on if I still go that route? I'm completely new to motorized bikes. Not looking like the older Trek mountain bike frame I have is going to work. It's near impossible to get all the bolts in for the sprocket without almost bending some spokes and also not looking like the CNC hub mounted sprockets will fit this frame due to a tapered hub. Thanks.
