Hello from Silicon Valley

I want to get into motorized bicycling. There are 2 spare bikes in my garage that are never used, and I want to motorize one of them. The spare bikes are both somewhere in the ballpark of 15-20 years old.


Out of these two, which engine kit would you recommend? Thanks.

After further examination, I will probably choose the first one as it comes with a free 6 month warranty, is $40 cheaper, and has an installation video.
