Hi,
I had an 8t Mac hub motor on my two former setups (58V battery, 30A from Em3ev): a diamond frame bike and then a recumbent with 26 inch wheel. It was in England so mild temperature.
I used it to do a 25 miles one way commute, mostly flat with two hills and 7 miles in city with numerous stops and starts. The Mac was not very reliable. The Mac clutch failed after 6000 km. The Mac had a good acceleration and was able to reach 35 mph but get hot too quickly. It is good for a commute of 25 miles. You can climb gradient of 8% but it will reach 100C quickly. The Mac motor is also noisy. I weight only 145pounds.The mac motor 8t cannot sustain 1500 W for more than 30 min, 2000 W for 5 minutes.
Now if you want something reliable and powerful go for a DD hub motor like the MXUS 3000W: I fed it with a 20S battery and 12F Nuculear controller and I can run it nonstop with 2300 W for hours on flat without overheating it and I am at 40 mph. I am just pulling 30A from the controller and 72V. The efficiency of the MXUS is even better than the MAC. this is another world and the DD hub motor is silent. The drawback is the weight.
cheers,
