[@davidhazel36]

I would like to try the flipsky dual motor controller to run my 2000w dual motor ebike, but I really don't want to lose the pas option as I use that the most.

[@stevecumming6427]

You've helped me as I watched you with the Flipsky a few weeks back & then saw something on best eBike controllers as of May 2024. Of the 4: Flipsky 75200 Pro V2 & Far Driver 72450 were the best. On Amazon that 75200 is $180. Now I see yours on Amazon for $100 like you said the 1st time. My eBike is 48V but it needs a new controller I think. This is smaller than the Heybike controller so would fit in the compartment.

[@EBikeBuilder_]

the 100 in the flipsky 75100 stands for 100 phase amps, I believe, maybe its 100 battery amps not sure, But its MUCH MORE POWERFUL than these hub motors require. If you are being SAFE and CONSERVATIVE - 60 to 75 phase amps ("motor current max" in vesc) is a safe bet. ANd 1500 to 2000W max power. But I have ran my G62 on 72V with 96 phase amps for 3 years so I didnt think anything would go wrong. But apparently after more research. yeah Be careful with the max phase amps because those motors can handle like 75 and this controller can do A LOT MORE than 75!! and the mechanical gears and stuff inside the motor just cant handle more phase amps. SO i have some videos coming up where I totally chewed up a nylon gear using 105 phase amps. Stay tuned Lol. With a flipsky you culd at least take full advantage of your current motor and battery. But it might be throttle only kinda thing im notsuyre how easy it is to setup PAS, i will have to look into that, im not into PAS but i know alot of people are... But yeah its a controller that can be moved from bike to bike as well which is nice

[@lewebvirtuel9503]

I would stick on fardriver because autodetection is better for hub wheels and tuning is far more intuitive than VESC. Side by side Fardriver is more heavy for heat dissipation and less prone to overheat.

[@ChrisOlin]

crazy coincidence. I'm currently working on effectively the same mod with a different model Flipsky to replace a Phaserunner that died on me this weekend. Got the motor spinning in the detection wizard, but I'm slowly getting through all the different parameters that need to be set. Trying to drive it with the throttle out signal on a Cycle Analyst because that thing wasn't cheap and I haven't found a better display to replace it with.

[@ChrisOlin]

yeah, it's possible to hook up pedal assist. either directly to the Flipsky or through the Cycle Analyst (which is more work and requires modding the Flipsky because it needs battery voltage for Vin) via one of the ADC pins. I hope you have a JST-PH kit and know how to crimp your own cables.

[@bismuth7730]

11:22 if your hub dosnt have any resistance when rolling it means it has internal one way bearing/hub, so the motor isnt really spinning when youre off the throttle. The Flipsky can not know the speed if your hub isnt spinning.

[@EBikeBuilder_]

@@bismuth7730 yup yup the geared hubs freewheel to coast by default, its the 1 way clutch inside the planet carrier that grabs onto the parallel key in the axle, ive since welded that clutch and now it has the slight resistance while rolling (barely noticable on fat tires) and can do regen, and makes the speedo always work in Vesc. Direct drive hub motors speedo should work as well, but geared hubs by default yeah the speed will say 0 when coasting

[@NoInfoFound]

Thanks for testing the flipsky with the G062. It would be interesting to see how the motor temperature tracks with power/speed. And yes, that phone mount (dismount?) ... :)

[@EBikeBuilder_]

i'd like to get a thermistor in the G62. But the motor cable that bafang puts in the G62 only has 9 wires; its missing the grey temperature wire. Even in the grin tech G62 motors, apparently. So with a phaserunner, you can send the temperature and speed pulses together on the same wire., And it figures it out. Flipsky ain't that advanced. I'll have to figure out how to get the temperature working at least.

[@dg9bfc]

i have seen modders who add some atf fluid in the geared bafang for lower friction and better cooling (and seal it)

[@KalLe1401]

I want the flipsky on my shengmilo s600 dual motor ebike, but I don't like that I have to replace my colour display with a phone. I ain't done any electrical work before so will need to find someone how i can pay to do it for me. Thank you for the video Ebike Builder 👍

[@Ro-Bucks]

I wish I could set my ebike settings. I got to look into something like this. thinking of grin technology's maybe.

[@EBikeBuilder_]

if U got the money the Grin Tech phaserunner and Cycle Analyst is better for an ebike, overall, as a complete system, IMO. but costs alot more. The cycle analyst you can actually see in the sun, and when your phone is dead. its a little more annoying to program the motor with the phaserunner suite, since it is computer software. There is an android version of the phaserunner suite in beta experimental mode, but it kind of sucks and some things can only be done on the desktop version. Its easy to get a motor set up with Phaserunner that Grin Tech sells/supports. If you are trying to do more of a DIY and use phaserunner to get it working with some other motor then Grin tech may not be able to provide help as well. But yea overall Phaserunner is solid and waterproof/potted, cycle analyst is great and can actually see it in the sun, But it looks kinda old school and its huge.

[@musmanov4642]

Hey mate, i ordered a dual bafang motor kit from alibaba. The seller says that bafang is supplying rm g062 750w back and rm g060 750w front motors. Do you think it's ok? The motors come with different casing. I wonder why they don't make both g060 750w instead

[@nicod974]

Probably because you don't need as much power at the front as the rear wheel does. MXUS does a similar kit with 1000w rear 500w front, which makes more sense to me

[@EBikeBuilder_]

Front G060 is 135mm , The g62 is 175 or 190mm , different physical sizes. The rear motor has the freewheel or cassette gears on it. And a longer axle. The front motor might have the cable come out the right side of axle. And the freewheeling clutch inside it spins in the opposite direction than the g62. When you open the front g60 it comes out drive side. So thibgs are slightly different. Mostly just which side the motor opens, and cable comes out. If you are buying replacement clutch it’s different for g60 and g62

[@ecocentrichomestead6783]

I'm waiting for the rest of my battery components to arrive but, Once I get the rack battery built, I am thinking of changing the controller. Question is, should I get a programmable VESC or an Ebike controller.

[@EBikeBuilder_]

@@ecocentrichomestead6783 vesc is good, but missing ebike features. For ebike features you can use a cycle analyst, which has pas / speed sensor / temp sensor/ brake cutoffs. The cycle analyst reads all your sensors and then sends 1 throttle signal to the vesc

[@DaVeHiLl200]

It only shows speed when you're on the throttle for the same reason it's not possible for you to have regen breaking boss, you have geared hubs that have one way bearing 👍😎

[@EBikeBuilder_]

yes exactly, it freewheels internally, i welded the clutch and did regen with it eventually

[@rymalia]

An easy 40 MPH on a BMX... is wild.

[@EBikeBuilder_]

this bike is a mongoose dolomite its 26x4" fat tires. Wheel diameter is like 711mm. or about 28" in the ebike speedo settings is what i usually use for the diameter. SO its a big wheel compared to a BMX wheel, I think when I used the grin motor simulator to see how fast a 20" BMX wheel would go with a G62 on 72V it said like 38 MPH or smething. It could probably still do 40MPH with field weakening on a BMX and have more torque with the smaller wheels

[@dg9bfc]

how much speed can one reach with field weakening on 52V on a 26x4 fat tire?? ( asking for a friend hi hi) ... no no I just wanna know if it's worth replacing my two controllers without overvolting.. so what does the simulator say?? (max pack voltage is 58.6 but it sure drops under load)

[@rymalia]

33:44 - would swapping in a Flipsky without making changes to a stock 48v battery do much? How much of these increases you show come from the controller vs the higher voltage? Is there any benefit in upgrading just the controller?

[@EBikeBuilder_]

if u add a Flipsky to a prebuilt ebike, u can set the Battery Amps Max to your battery BMS max discharge amps. So it wont pull more than 30 amps or whatever. Then yeah it depends on your existing controller. But in general lots of ebikes arent really using a controller that unlocks the full potential of the motor, its just a basic square wave controller. The flipsky is. sine wave FOC field oriented control. And can do field weakening and has lots of features that the basic contrrollers dont have. Like most controllers you might have some "P settings" parameters screeen with a bunch of non-sensical numbers and values where you have to look up what everything means and decode it every time you want to change anything. The flipsky is VESC and you can install vesc tool ferom the app store and flipsky 75100 prov2 has the bluetooth module built in which is nice. Super easy to program it. Butto answer your question, you can at least take full potential of your motor with the Flipskyu, after I have messed around with this more and done some reasearch. I would only recommend like 60 to 75 phase amps for these motors probably, unless u have spare nylon gears on hand. Is a safe amount. So the phase amps would probably be better than whatever controller you have currently, and it would have stronger acceleration off the line. Can be moved from bike to bike and reprogrammed etc. Vesc has alot of great features. You could probably increase your top speed by 5 to 10% with field weakening. but it could run hotter and may require temperature monitoring

[@lukenorton8243]

So which one do you like most The phaserunner or flipsky I was looking at both and then saw this video Phaserunner is more than double the price ?

[@EBikeBuilder_]

@@lukenorton8243 phaserunner is nice if you want plug and play , with water proof connectors, cycle analyst is cool and basically required along with the Mfswitch. Or grin has the super-H kits now if you don’t want a cycle analyst, but id highly recommend the ca3 with the grin stuff. Ca3 does a lot of stuff the phaserunner doesnt, in terms of throttle, pas etc. it fills in a gap in the grin ecosystem. Now the flipsky is a lot cheaper, but more DIY and lots of wires and stuff all over. Its not water proof, wide open holes where stuff can go inside it. But in terms of performance the flipsky feels very similar. There’s s lot of features of vesc that i really like 👍 and the vesc tool is great. I think vesc is the future for sure. The phaserunner is a much less appealing option now due to the availability of much more affordable controllers like the flipsky

[@lukenorton8243]

@@EBikeBuilder_ thanks so much for the reply. Honestly didn’t know how many options there was 🤯 For simplicity though the phaserunner would be the easier way to go you think? Like a dummy could do it? Wiring it in and setup with computer. Also grim doesn’t have an app do they. Just wire to computer for setup ? I would like one of the grim motors eventually Thanks again man your videos are super helpful

[@KuruptViet]

Is there a way to that you can choose the speed or gear? Like low, medium and high?

[@clintwedel5704]

How does it deal with Pedal assist? Also interested in the regen braking setting and performance.

[@chesteryao]

With geared hub motor the speed drops to 0 with no imput. But with direct drive motors it is continuous that's what I noticed. Btw share your adc1 input settings.

[@EBikeBuilder_]

ohhhh yeah i get it , makes sense. So when You check "direct drive" in VESC, its more like "Hub Motor", is what that seems to mean. Now I understand why BAFANG uses the speed signal. and can't just go off the motor RPM, that freewheeling bit of the clutch assembly. My ADC1 stuff I just set to defauls pretty much. The throttle i have goes up to 2.73V max when its on the 3.3V line. And then i set the throttle center point just eyeballing it 1.73 or something, the numbers were on the screen for a second I was getting frustrated with it lol. But the throttle curve is just like defaults Polynomial and i didnt use any throttle expo or anything, didnt have to mess with the throttle much like I did with the BBSHD. This motor doesnt spin 10000 RPMs like the HD so the thrrottle was easy to setup.

[@Legate_Lanius]

@@EBikeBuilder_ is it possible to hook up the speed sensor wire to the flipsky so it reads the speed at all times?

[@lukewalker1051]

Curious if you have a mechanical or electrical engineering degree? You make many references in your videos that suggest you have such schooling....like putting the Flipsky against the seat tube for increasing the heat sink through thermal conduction. Thanks for your educational videos.

[@JasonNosajasoNosaj]

Did you figure out the 60% max duty cycle at 1:08:00 ? to get 3+kw?

[@EBikeBuilder_]

@@JasonNosajasoNosaj yeah i think vesc has settings that limit it by default to 80 or 85 ish. In addition to wattage limit and battery current limit. The motor max/ phase current influences the duty cycle as well. I’ve got it going more for sure just increase the motor current to like 80 or 85. And the battery current to 35. Or when you do the motor setup, try more max power loss , like 300w To 350W, it will result in a higher motor current max, just make sure its not above like 85 ish , maybe less like 75 to 80 motor current max for longevity

Thanks bro looking Too Do My Own Build When My Current set up Dies , Good Info Cheers

[@EBikeBuilder_]

flipsky 75100 pro v2 is a great controller for up to 72v. Some differences from typical ebike controllers tho- it doesn't use a wheel speed magnet/signal, it goes off the motor RPM. So some quirks related to the speedo. If you have a direct drive hub, or weld the clutch in the BAFANG hub, the speed would show up correctly all the time. With the geared hub, it freewheels internally when the motor isnt spinning, so the speed doesn't show up in the VESC app when I am coasting. But the speed does show up when the motor is going. Also its kind of hard to see my phone in the sun Lol. But the flipsky is very inexpensive and works good so Its hard to complain, I really like it. Thanks for the comment my Bro

[@dg9bfc]

in fact without overvolting there is not much gain if your bike is already a beast with dual motors and 48 or 52v

[@EBikeBuilder_]

it doubles the torque if you use both motors at the same time. Great for going up hills or acceleration. But when you get up to speed i generally only use the rear hub. Because the front one is loud and noisy. And its unnecessary to use the 2 motors most of the time. Over volting to 60v or 72v will push it up closer to 40mph. And on higher voltage there is less heat at the same current. ALso AWD can be great in the snow or sand if you ride in really bad conditions. But yeah in many cases the front motor is a novelty that you dont use all the time

[@dg9bfc]

I can already use both motors ... 2x 25 Amp controllers. selectable rear or both and reaches near 60kmh with no modding... just will add a second battery in parallel cause two motors at once are power hungry 😂 it's a seeker 26

what is your top speed with this motor?

[@EBikeBuilder_]

with bafang Rm g062 1000 DC 6T windings on my 26" fat tires (more like 28" or 711mm diameter) the top speed is about 40 - 42 on flat, you can increase it by maybe 5 or 10% with field weakening. I have another G62 from Grin Tech that is 6.5T windings so its more torque and its still doing a good 40mph without any field weakening

[@quantumfx2677]

@@EBikeBuilder_ A good 40 is not bad, How is it on hills? If I can find a good hub getting a good 40 and good torque for getting up at least a 40° incline I can live with that without going into a middrive.

This is very nice build; but i would'nt go too far wearing a flipsky on the bike. I MUST admit it's huge difference vs stock controller but watch your wheel wire toast (let's say fry).
