It is quite a low KV motor so it has a lot of torque, you could most likely decrease the pulley ratio to get a higher top speed. Also, have you customized the programming on the ESC?
hey! it is a low kv indeed yeah the ratio is definitely modifiable but I was aiming for no speed loss uphill and this does it for me :) I had a look at the ESC's power delivery settings too but the original setting worked well so I found that modifying them wasn't necessary. I find it to be a perfect combination of torque and speed :D did you build one?
+Sean Pain hi Sean! Yeah you bet its low kV! I havent found any lower kv ^^ Well the thing is I was looking for power uphill and personally I find 25 km/h to be a comfortable riding speed any faster and you start looking dangerous when riding along the lake side :) I did I have a look at the ESC's power curves because I thought the acceleration was to hard but after riding for a few days I got used to it and decided to keep em at the original values. Do you have a board?
+Sean Pain hi! Yes the ESC's is tuned perfectly via USB. I am happy with my top speed I don't want to die lol. I kept the speed at where I would be naturally pushing the board. So it feels nice when riding.
So im propably going to buy an electric longboard for 250 euros that looks like a diy and is a 500 Watt... Here in my city we have 45-60 degree hills... like everywhere... do you think it will be able to get me up the hill?
+Alex Mavromati for a rider of 90 kg, with a board weighing 10 kilos and a road angle of 60° ie 173.2%. You would at least need 3.6 kW of power to get you up that hill at 25 km/h. That is taking into account friction and drag coefficients .
That's great but you must realize that power doesn't necessarily mean speed. It all depends what you want to achieve. I need mine to climb hills so I need a lot of power and high gear ratios. I could have bought a high kV rating motor to get more speed yet I would have lost torque.
+Thien Le Trong Hi! It goes about 25 km/h and will last for 15 to 25 minutes using a 5000 mAh 6s LiPo - depending on use. You should cover up to 10 km. Hope that helps!
wie schnell fährt das teil denn? sieht nicht wirklich nach mehr als 25 aus.. ich könnte dir ein paar Zahnräder 3d-drucken, dann kannst du mal andere Übersetzungen ausprobieren.. Porto und Materialkosten musst du aber bezahlen.. bei 2 Zahnrädern denke ich ca 5€ Material je nach Übersetzung. Zu den 3,2kw.. mein Board fährt mit 1kw knapp 44 Kmh, ich könnte aber bis 52 hochgehen und wäre noch im Rahmen meines ESC und Motor (2,2kw) Sieht irgendwie mehr nach 5-700W aus, was du da momentan fährst.. wie die anderen schon schrieben.. falsche Übersetzung.. wenn du nur 25kmh höchstens fährst, nutzt du nur maximal 1000w je nach Anstieg, ausser Offroad natürlich :D
+acab yamum Hallo! Mein Deutsch ist Leider nicht gut genug um dir eine gute antwort auf Deutsch zu geben. Ich hoffe das du Deutsch/English verstehst. Genau! Ich fahre zwischen 25 und 30 km/h it depends if I'm riding up hill or flat. Ich nutze glaube ich das ganze Kraft der Motor, the thing is that the kV rating is extremely low and so the speed is dependant more on the fact that my battery pack is a 6s and not a 10s even if the total work provided by the engine could be equivalent in both cases the speed will increase with higher voltage not with more amps. Ich wollte auch nicht schneller fahren können weil ich finde es wirklich zu schnell für den Stadt und brauchte am meistens torque um eine schwere Last aufheben können. Regarding the Zahnräder, could you send me a private message to show me what you mean with a picture or a cad file? I would love to try it out! Let me know soon! If you need measurements please tell me! MFG
Yes, first of all i would need your KV rating and your wheel diameter, so i could calculate different gears. the CAD then depends on which wheels you use and what type of belt (HTD 3mm or 5mm) just write me a pm please, i dont know where or how ^^
+acab yamum Hi! It looks like that because I have insane torque and very low top speed. I made the calculations in order for it to move at 25-30 km/h and go up hills like it was nothing.

wow. i hope that i can build my own diy e- skateboard this year.
its been nice here last few days uk
+gadgetman 404 lucky you! It's been cold in the alps brrr
cool dude nice work
Cool
dude live stream when on board how cool would that be
That would be cool to do! Perhaps later this summer when the weather is consistent 😎
nice dude! looks like its workin great! how steep are those inclines?
Hi I just calculated the average slope. The average rise/run is 5.3% with a standard deviation of about 0.85%.

+The Green Bandit not yet, buy I do have experience with using hobby motors. All of my parts are on the way for my build :)

I will let you know. I will make a small calculation.
+Alex Mavromati for a rider of 90 kg, with a board weighing 10 kilos and a road angle of 60° ie 173.2%. You would at least need 3.6 kW of power to get you up that hill at 25 km/h. That is taking into account friction and drag coefficients .
500watts?! that will only get you to like 10kmph on a flat road never mind a 60° slope
+David Hall mine use no more than 400 watts on flat road doing 22mph and i weight 100 kg
That's great but you must realize that power doesn't necessarily mean speed. It all depends what you want to achieve. I need mine to climb hills so I need a lot of power and high gear ratios. I could have bought a high kV rating motor to get more speed yet I would have lost torque.
How fast was it? And the range too?
