Yes that's the one, but I upgraded the kit with a custom 25mm belt and 6" pulley to slow the cadence. It was my favorite bike of all time, well that was until today when I unboxed my X1

Is that the 2015 GNG with the 20mm-wide belt? I have that one too, and it is so loud. I can't imagine how loud the chain-driven version might be.

I went with the Ludi upgrade and I'm glad I did, I live in an area with lots of great steep trails, it climbs like a goat and just floats on the downhill. I hung it in my garage next to my Cannondale W/GNG belt reduction kit and did some sound comparisons. I held the decibel meter at 4' above the crank and ran the throttle wide open the GNG peaked at 85.5 decibels the Bafang M600 was 59.8 when i let off the throttle the rear freewheel peaked the meter at 60.4. With all this discussion about how loud this motor is I was a little worried but once I rode the bike I realized it's not a problem at all, at least for me, I thought it was funny the freewheeling rear wheel makes more noise than the M600. I took one more test at the end, I rode the bike down the street with no power just pedaling, third gear, flat ground, light headwind and the meter peaked at 71 db. Great Bike, Very good value.
