Hi, I’m a 180 pound rider who loves high speed and long range with aggressive riding (don’t we all) looking to build a board with 40-45mph capability and 40-50 mile range. Roughly $3k budget. I’m still in the beginning phases of deciding on parts and this is where I would greatly appreciate input.
This is what I have in mind currently, nothing set in stone whatsoever.
dual 4000 Watt 190kv flipsky 6384 motors (What are advantages of 10mm shaft vs 8mm?)
12s8p Battery (not sure where to source or what cells are best)
Undecided on trucks, looking for the least amount of speed wobble, I’m ok with sacrificing the carving aspect to stay on the board at high speeds lol.
Would like to have pneumatics on the board as I would like this to be a comfortable street / sidewalk cruiser, but if the speed & range is sacrificed too much I am comfortable with other options. 0 experience on pneumatics, just seen videos.
As far as ESC goes, to my understanding I just need to keep amperage max 5-10 percent higher than motor draw, if there’s anything I’m missing besides this that I need to keep in mind I am all ears. The current one I have in mind is flipsky Dual FSECS 6.6
As far as gear ratio goes, I’d like it to be in the ballpark of 40mph with enough torque so it doesn’t put a crazy load on the motors. Looked at 2:4:1 (15t motor pulley to 36t wheel pulley) ratio on 120mm pneumatics which gave me a 41 mph weighted theoretical max.
If there’s anything y’all can tell me that would make this a dream build, please do not hesitate I aim to be an information sponge. If you have a build that is similar to what my build goal is, please drop the parts list 
much appreciated.
