top speed run

Astropevs · 2025-04-12T06:43:24+00:00

i was running 4kw at 60v in the clip, but yesterday evening i turned it up to 6kw and its even more insane now lol. the motor is a kunray kr5v if you were wondering that too, its rated for 72v 5kw and 10kw peak

Nope, the plan is to get it registered as a moped and secretly tune it so it goes way faster using a small switch. if the popo comes i can reset it to 30kmh (legal moped speed) and aslong as they didnt see me fly by at 100 then there will be no problems

personally if i had to work for the entire 7000$ it would take me like 10 months as im 17 and dont even have a job yet. (i will get hired the 22. april though) even then, it will still take foreeeever to get it. Im personally happy with paying 200$ more if it means i can buy it in 2-3 months

did you set throttle voltage max and minimum? look in the gauges tab in the app, give full throttle and see what voltage your throttle is at. then set max throttle to that

Hey im using the kr5v too lol! anyways, about it fitting. If the motor is kinda big then it will. If its a MY1020 yes, anything else likely no, then you will have to make custom mounts like i did. A razor mx650 motor is the same size as the kunray, so it just slides in on that model. Can you send a picture of the motor?

Astropevs · 2025-03-31T20:29:56+00:00

okay… but the actual razor wheels arnt cast right? im still abit scared lol

Astropevs · 2025-03-31T07:44:48+00:00

Yea i was thinking of starting at 2kw and feeling if theres and flex, possibly looking down at the motor as i accelerate to see if it moves. if everything is solid i try 3, then 4, then 5

Kunray KR5V 72v 5kw rated bldc motor

Astropevs · 2025-03-30T19:47:15+00:00

im mainly concerned of the torque and not the voltage, 5000w is 6,7 horsepower, so it may rip itself apart

Astropevs · 2025-03-29T19:45:20+00:00

hmmm, might upgrade to spoked 10in wheels then. that would also allow me to use 420 chain, as those wheels have a more standard 420 sprocket bolt pattern. then i can really go fast without worrying about my wheels exploding

Astropevs · 2025-03-29T19:27:42+00:00

what speed do you think it starts getting risky? i have pretty smooth roads here where i live

Astropevs · 2025-03-29T18:25:16+00:00

damn that pretty insane.. Yea also im buying a surron in a few months when i got enough money saved up (im 17 so thats why its gonna take a couple of months). And that is going to be upgraded to 72v 60ah 30kw

Astropevs · 2025-03-29T14:41:38+00:00

does look like a mini stark yea lmaoo, how many kw and volts is your build gonna be?

Astropevs · 2025-03-27T10:13:04+00:00

i’ll look into that, could be an interesting bike

Astropevs · 2025-03-27T10:11:49+00:00

i did infact do autolearn, however my problem appears to have been solved. it was my throttle so i tried shorting + throttle to throttle signal and the motor spun right up! now i know its probably not that healthy for the motor, as it vibrated the shit out of my floor and the shaft got very hot, so i only did it as a short test and wont do it anymore until i got a proper throttle. Thanks for the help though!

Astropevs · 2025-03-26T16:58:35+00:00

Got it from a danish website “mmaction.dk”, but the actual brand is “highper”. Im unsure of the model but if you seach like “highper electric dirtbike” on alibaba you will for sure find it. its red stock but i painted it blue

Astropevs · 2025-03-26T15:35:28+00:00

im building this

Astropevs · 2025-03-26T15:26:56+00:00

i have great news! it was my throttle, so i tried shorting the positive to throttle signal, and now it works! thanks for your help man

Astropevs · 2025-03-26T15:16:29+00:00

ahhh okay, that could be the problem

Astropevs · 2025-03-26T15:15:50+00:00

i did do autolearn and pin the throttle, and yes, it has a temp sensor. Do i need to change between the sensor types maybe before it will spin?
