I had my Pace 500 for 1 year and 1300 miles. It was comfortable powerful and pretty much hassel free. It didn't have throttle from start which bothered me and I wanted to try a torque sensor instead of the cadence sensor. So I moved on to a Lmt'd from Ride1Up. It has an airfork, higher torque motor and the torque sensor. Way different ride as you control the power via the pedals So the Pace did good for a year and we'll so how the next year goes.
