I don't own an Ohm. I've ridden the 500W bionx powered Ohm. Yes, it's right up there with the Turbo S and the Strohmer. I have a 350W bionx on a touring bike. Bionx has been very reliable. Bionx does have the throttle option... I never installed it. If you really want to explore the world of e-bikes in the Portland area, I suggest you make a trip over to the ebikestore on Rosa Parks Way and talk with the owner, Wakefield Gregg. The ebikestore did the installation of my Bionx kit to my touring bike. However, they carry a bunch of different brands of ebikes and it is the entire focus of their business.
