And I've ridden both too and I say they are similar on assist levels, with the Ride1up plenty strong given its own limitation of 25mph max speed versus the 28mph for the Pace. And they both produce that speed from similar 500W motors. The difference is 12% in top speed between the two and maybe that is what is the difference you "feel". Remember that the Ride1up used to be $999 when I bought it (and included the LCD display) while now is $1200 and no LCD (vs the Pace which has stayed $1400). So the price difference used to be 30% more for 12% more speed while now is 16% more for 12% more speed (and you also get hydraulic brakes and LCD display versus +$55 for LCD on the Ride1up). So IMO given these current prices, the Aventon Pace 500 is clearly the better buy now.Ive ridden both and no they don't. He is right about how weak the R1Up is.
