Will Dacs' 70cc fit this bike?

[Kncool]

Hi I ordered a Dac's 70cc motor, and impatiently waiting for it to come.
Heres the bike I want to install it on.

Im concerned that it wont fit, the bike is aluminum. It has a very fat frame as you can see in the picture. What do you guys thing and if worse come to worse, what are my options?
