What's up... One piece crankset question

[pduke]

Hey all, thanks for the sweet site that this is. I'm looking at getting a Cyclone 3000w. Currently breaking down an old Schwinn and it has a single crankset (crank piece?). Do I have to replace it with a 3 piece set?

Thanks for any feedback.

Cyclone installs are always more difficult than say bafang drives. And legal too
