60:20 would be 45+
Really like this build. How stable were your front light mounts - did the beam bounce about? (Planning something similar)
Love the trek theme, I think I need some LCARs styling on my next frit attempt
Max Iāve been able to get out of my Avio Drives has been 38mph with 220kv maytechs on 12s. Not sure how much faster I want to go on the Bergmeisters. Would be nice to graze 40 and see how they do
Ooo, I like that idea.
They arenāt badā¦ the cheap brackets are soft enough that they absorb the worst of the vibration. I have yet to make anything permanent to replace them.
Itās definitely possible, but it seems like the majority tends towards a 1:4 ish gearing with the bergmeister wheels.
If thereās sufficient interest, larger pinions for lower gear ratios is definitely an option, to accommodate the speed demons here
I would love to have the option!
I see your order has already been delivered successful.
did you get a chance to check the calculated kv through vesc tool on those motors? just curious for science! :0
My FSESC 6.6 dual freaked out and I had a lot of stutteringā¦ I ended up backing down from the latest firmware to trusty 3.58. The board is up and running but I havenāt finished much in the way of tuning. Iāll check KV tomorrow if I get a chance.
ā¦top speed is around 31 MPH with these 200KV motors and 16T pulley, as opposed to 33 MPH with 190KV and 15T.
Something does not add up.
lambda = 60 / (sqrt(3) * pi * kv * pole_num)
which means:
kv = 60/(lambda * sqrt(3) * pi * pole_num
I calculated the motors to be 164.0 & 164.4 KV. My Haggy 190 KV motors were calculated to be 182.8 and 183.0 KV.
This is a large enough discrepancy that Iāll check with Maytech - perhaps I received 170KV motors.
Oh wow! That is a large discrepancy. You can just type KV in the console and divide by pole pairs (or numbers) to more easily check. Surprised that it was such a large discrepancy.
Awesome, I couldnāt remember where that was. Yesā¦ I even have 16T instead of 15T pulleys and lost speed.
Oopsā¦ delayed response.
Yes, the motors are simply the wrong KV. I get the same results with multiple VESCs. I ended up keeping them, as they will still go to use even if I replace them with 220kv 6374s when I switch to AVIO drive. In the meantime, they have at least been reliable!

2020 goals: shoot more video and ride often. Day one was a success! Here is the first video with the Eskate Enterprise in Rocky River Reservation; one of the Cleveland, Ohio metro parks.
Great video dude, nice board and editing! Im getting into youtube aswell will take some inspiration from this.
Thank you! Iāll look forward to your videos.
