...i think it's pretty ugly. dunno how good the motor would fit.
but, the way the top tube(s) are, it looks like the stock peanut tank would fit right in there, and it wouldn't look like you're carrying around a black football on top of your frame, like they normally do.
it might. i'm just not into the frame style that much. the seat tube looks really high. but then again, i'm only 5'7".
it's all up to you. if you like it, and the motor fits, buy it.
I was checking out there stretch cruisers a while back, they seem pretty sturdy... but then again that is basing off of the pics (tubes look over sized, forks look strong). Salty that bike would look sweet with a gas tank on it, I had a heck of a time with my coaster arm clearing the sprocket bolts... I will probably never again do a beach cruiser build with coaster brakes haha.
It looks like it will be a tight fit. Just guessing but I would plan on having to use a custom intake so that the carb can be mounted to the side a bit. A custom front motor mount will also be required but that is normal.
