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.

Rusty the hub has to be flat, no taper, for the hub adaptor to work. The best and most common hub size is 1.5" diameter as it has more surface area to "grip" the 1" hub size adapter is very prone to slip and this damages spokes. 26" wheels with 36 spokes is ideal, more spokes won't work. 24" wheels with 36 spokes is tight but will work. Larger diameter wheels will work but often have oddball hubs. Cruiser style wheels are what most use in 26" 1.5" hub & 36 spokes.

Tires wider than 2.2" can cause problems with chain rub on tire sidewall, but I have carefully fitted up to 2.5" tires that barely clear. This is a problem mainly when using the China kit engines.

Frame triangle space is an issue, motor has to fit and some triangle frames are just too small to fit the commonly used gas motors. If there's sufficient space in the triangle you can motorize it with a gas engine. If not find another frame or use electric motor to power the bike.

Obviously many frames work look at photos in the forum to find frames that suit you. This hobby is a learning process, but thankfully there's lots of examples of what has worked to get you started. Unfortunately there's a great deal of mis-information out there so always take any free advice with a grain of salt, mine included. Think it through and always measure twice before proceeding.
