I went with the highest (5.2) ratio with my 190kv 6384’s.
My thoughts thus far are that I still have my motors set at only 77a instead of like 120, and I haven’t gone past like half throttle yet.
Everything on this board is too new to me to ride it hard yet. When I release my review video on the drives, I’ll have put at least 100 miles on it, but I can’t offer too many solid opinions yet.
I’ve only ridden it a little bit but it’s been awesome so far, with tons of torque.
If you are getting a lower KV, feel free to go with a lower ratio, but if you go with 190, I think you will be happy with the amount of torque on 5.2 for a mountainboard. Again, preliminary thoughts.
