Re: Commuter Bike Build - Would this work?
Welcome to the forum. At 120lbs, the Skyhawk should move you down the road very well.
I have not used a Skyhawk, but my 48cc China girl motor moves my 200+lb girth down the road pretty well.
A steel beach cruiser from Walmart should work fine. I would add a front brake if it does not come equipped with one (a front BMX caliper brake is cheapest and will do the job). Coaster brakes are not designed to stop you from 25mph without some help, and cars will turn in front of you.
