Hello everyone,
Im new to the forum but im intrested in building my first electric skateboard. Ive done some research and i just want to verify everything will work out before a spend any money.
My ideal set up would be a rear dual drive with top speeds of 20mph and a range of 8+ miles.
But for simplicity for my first build i decided to stick with a single motor but would like to keep the option open to later on adding a second motor thus i choose a smaller size motor.
This is my part list so far
(I have miscellaneous parts such as the belt and a motor mount that should work)
Motor: kd 53-20 brushless outrunner 195kv
Batteries: 2x Zippy 2200mah 4s 25C (i want to use two 4s batteries for more range rather than a single 6s or two 3s) not sure if it works like that
ESC: hobbywing Quicrun-WP-8BL150 Waterproof ESC 1/8 Car SCT Monster Controls
Please let me know if you see any issues or improvements on this build. I wish to obtain a 20mph top speed a 8+mile range and really wont be tackling any large hills mostly just flat bumpy paved roads. Also im about 150 pounds and 6 foot
i second what @cmatson said. i ordered this same esc with hop[ping to pair it with the space cell and r spec. this was before i knew anything and realized that the esc is only rates for 6s. i still have the esc so if you still whant to purchase it i can sell it to you for 80$
6S ESC w/ 6S LiPo should get you about 20-23mph with a higher KV motor. For the most part that’s all you really need if you are only trying to climb 15% inclines.
If you want to climb higher inclines then a dual motor setup is ideal. If you are completely flat ground a single motor setup is your best bet.
Thank you for your feedback. I foolishly assumed that getting two 4s batterys would give me better battery life. If i got this motor,

Would i be able to possibly fit another motor incase i wanted to add another one down the road. Also that motor seems to be rated for a 10~12S so would that mean i would have to get two 6s batteries? Thanks for your patience
8S will give you more watt hours which is a bigger battery. You’ll get more power + more range (depending).
That motor will handle 10-12S and you can always upgrade in the future to 12S. Just make sure the ESC is capable.
Battery life is about 100-200 cycles or so… Sometimes longer depending on how you take care of it. I usually only charge to 4.15v and discharge to 3.8-3.6v.
HobbyKing typically has a sale once or twice a year for cheap RC LiPo packs that are 50% savings.
I don’t think you need to worry about the voltage rating of a motor. It just tells you how high you can go. You can perfectly use a motor rated for 10s at 6s.
The kv value (revs per volt) will tell you the max rpm at your voltage.
The motor you linked above will work perfectly.
