The Electrek guy, Micah Toll, explains the pros and cons of belt drives using his personal Priority Current as an example --- so probably a review to come from him in the near future.

The Priority Current is a commuter-oriented electric bike that delivers a seriously nice all-around package at a more than reasonable...

for Toll's review of the Current. I pretty much agree with all his conclusions, but I do have a few minor criticisms.
1. No brake inhibitor switches --- probably a carry over from their Embark Bosch design. I view this as a backup safety feature with the added convenience of adding a brake light if desired. Note, while we're on the subject of brakes, I replaced the front 160 mm with a 203 mm Magura Storm rotor I had lying around which greatly improved the feel of the brake lever (i.e., modulation feel). You'll need a post to post mount adapter and some new m6 bolts to do this.
2. Coming from a full suspension Frey CC as my first ebike, the hardtail/rigid fork Current's ride seems harsh. To help I added a full Kinekt system including the bodyfloat suspension seatpost/Brook Flyer saddle combo and their 30 degree suspension handlebar stem (to install the stem you'll need a riser adapter to replace the adjustable stock stem). These additions considerably improve ride comfort, but they're no substitution for the Frey's pretty sophisticated full suspension setup.
At the non discounted price, not counting shipping, both the Current and the Frey CC come in at about 3 grand. I have 1100 miles on the Frey and 150 on the Priority. With the stock controllers both are "non jerky" and ride just like an enhanced bicycle although the Frey with the ultra Bafang motor feels more powerful at all lower PAS settings plus it has a left thumb throttle which the Current lacks. But at PAS 5, the Current feels similarly torquey as Toll describes, seeming capable of climbing any tractionable hill. Note the Frey comes only in one size while the Priority comes in S,M. and L. At 5-8 29 inch inseam the S Priority fits me better than the Frey, but I guess I've adapted to it. The Frey is a big relatively heavy bike so it's not probably a good fit for smaller people, whereas the Priority maybe 15-20 lbs lighter with slightly skinnier tires (1.9 vs 2.4 inch) feels a bit more nimble and lithe to ride.
I've had no issues with the Shimano Deore shifter on the Frey, and although I haven't gotten around to checking the chain wear yet, I suspect to be able to get at least another riding season out of it. I did add an outer chainring guide/guard to keep grease off my pants/socks. There are entire separate lengthy threads on belt/IGH vs conventional chain derailleurs, so I won't go into that here.
