I went through the brushed aotema,, the BD36, then went ahhh,, when I got the brushless aotema. What makes me facepalm was my posts gushing how much I loved the brushed motor.
The brushed could not handle my climate, and a ride over 10 miles long. They'd melt on the hill. Work was 15 miles, so I was doing things like biking to a bus, ride the bus some, then bike some more home. Eventually I got a car rack that could carry an e bike, and I'd park at the bottom of the big hill, then ride in 9 miles to work. All the aotema stuff was front hub only.
The brushless aotema was nice. Like I said, with a 48v battery, it beat half the field in that gasser race. It totally slayed the 50cc bikes. But it still suffered on hills, I guess, mostly because of the smaller diameter and less magnets. This motor was near identical to the 407 crystalyte, but it had no halls. so sensorless.
The next motor was my first 9 continent type,, a 2009 version E-Bikekit. Still a front hub. A 9x7 wind This motor climbed the hill much better, getting less hot. With this motor I could go to the real mountains, such as my beloved Emory Pass on NM 152. This road is 10 miles of twisting hairpin curves at 8% grade. Very fun to ride down it, but no so fun to ride up. We used to take 10 speeds and a pickup, and gravity race it back in the 70's.
