I’m quite new to this sub and have been lurking and trying to navigate the forum for the past few week(s). I utilized this lurking time by studying, for a lack of a better word, how to build an E-SK8board. I do not really have a budget, other than that I wish to spend the least amount of money, while not skimping on quality parts.
My goal is to achieve a stable 25~30 Kph ride with around 15 km range, and easy charging. From what I have gathered, by studying on this site alongside other means of research, the three most important parts are the motor, battery & esc/vesc. I believe I have selected parts which should meet my goals. Nevertheless, let’s get right to it.
Starting off with what will drive my board forward, the motor: Turnigy D5035-125KV Sensored Brushless Motor
Note: From my understanding, this motor has great torque, but lower speeds.Further, I believe the torque also helps with climbing hills and such and keeping stable speeds overall. Which is why this is my pick. (Suggestions for other, better, motors are appreciated)
Next up, the battery: ZIPPY Flightmax 5800mAh 5S1P 30C x2 in serial (so 10s at 5.8Ah - 37v)
Note: This will give me 5.8 Ah, and since it has an alright C-rating, I believe it to be a good fit for my motor (and ESC/VESC??). To be honest, I am not sure what 1P means in the name. I picked this because I thought I’d want one with an alright C rating, and because my motor says it’s capable of 8 - 12S batteries. (Again, suggestions for other batteries are appreciated)
Followed by the last important part, the ESC w/ BEC or VESC: Turnigy SK8-ESC V4.12 For Electric Skateboard Conversion w/BEC
Honestly this topic is the one in which I am the least knowledgeable about. I am not entirely sure exactly what to look for, other than that it needs to be capable of driving the motor and receiving from battery. I also know that the BEC is necessary for actually controlling the skateboard. I have looked at VESC, but they are almost doubled the price sometimes. Maybe there are ones that I have missed and are better than ESC, if you know of some, then please don’t hesitate to suggest.
Now for the smaller bits and bobs, starting off with the drivetrain & pulley-kit and so on. https://www.banggood.com/DIY-Electric-Skateboard-Kit-Parts-Pulleys-And-Motor-Mount-For-80MM-Wheels-p-1146629.html?gmcCountry=SE¤cy=SEK&utm_source=googleshopping&utm_medium=cpc_elc&utm_content=vivian2&utm_campaign=pla-all2-se-pc&gclid=EAIaIQobChMI4Kmk8pjX2gIVEhsYCh0VEACBEAQYAiABEgKnaPD_BwE&cur_warehouse=CN This one’s quite cheap, but I am not entirely sure about the amount of teeth for the Pinion and spur (which is arguably important for achieving high torque and speeds ) . I hope it’s metal, but it could be plastic. I want one which is stable. I am not entirely sure if it’s entirely compatible with my motor (shaft size and all). Also, how do I know if it fits with my trunk? Is the size standardized?
Note: Would love your input here
Next up, wheels: I have not selected any wheels. Other than I know I want 83/90 mm wheels. And from what I know, the size will also dictate which motor mount & pulley that I should purchase.
Skateboard: I am looking for one on the cheap. I am certain it is going to be a longboard, however.
Trunks: Again, I am not entirely sure about this area. I would think that the shaft size matters and the shape of it, other than that, I don’t think much else matters. Hopefully I can keep the trunks that comes with the longboard.
Controller: Bluetooth & Phone - is this possible? (Coding dedicated software), could really save on the build this way.
The total build price, the longboard aside, is around: ~300 euros (likely to be more).
On another note: I have never skate before, so I am not sure how fast is fast. I reckon a bike to ride at around 15~25 Kph. I would not need to skate faster than a bike.
Also, am I right in thinking that higher torque = stable speeds in hills and normal roads alike?
Any input, any suggestion etc is and will always be appreciated. I am here to learn, to build and to skate. Hopefully this build with satisfy my skateboarding needs.
Yours truly, a fellow eskatebuilder.
EDIT: After some very intense , discussion with my friend. We thought this motor: might be better suited
what are the thoughts on this motor/ new edited setup?
