[@charlesdavis124]

Congratulations 🎊 I have the 7280 on my bike, so I know how powerful the Sabvoton is. The torque is in the throttle settings! Trust me. Download the manuals and play around with you settings until you find what you like. I get the "controller protect" fault only when I'm in like 5th PAS and I hop of a crub or hit a hard bump when I first start moving. Be careful with the Flux. It will make your motor put out more RPM's , but the motor and controller may get hott. Have fun, bro

Ill have mine in a week or so.

[@maximumchargeEV]

oh wow you are going to FLY on this bike.

[@KingKola_]

Love it... If your motor starts to struggle too much, you may benefit from adding statorade, and no you won't have to re-do it often. The heat building up might be the reason it slowed down. Also, i have that same ukc display, you might want to make sure the display isnt limiting your current in the advance settings. Overall the bike is solid as it is. 50mph is of course not necessary, but it's nice to have that option just like most cars can go 120mph.

When running high power thermal rollback is required. Does motor have thermistor? Field weakening causes heat buildup.

[@maximumchargeEV]

it has the thermistor, but I have no way to read it because the controller doesn't support it. Any ideas on how I can read that sensor with some other type of device? It's the white wire near all of the hall sensor wires.

[@rufusirvin5279]

@@maximumchargeEV sabvoton controllers are like BIC lighters disposable. There are far better controllers that support thermal rollback. That field weakening really adds to heat. White wire is for speed. Grey wire is thermistor. Some controllers like ASI and Phaserunner support duplexing of speed and thermistor by putting speed and thermistor in parallel then hook white wire to grey. Definitely fero fluid will help. Does that sabvoton support variable Regen? Would definately help in your braking and you would not have to upgrade brakes plus save on brake pads. Probably cheaper to get a controller with thermal rollback and variable Regen than replacing a motor . If bike feels Shakey try a fork stabilizer.

[@NoOneUnique-um1vo]

You might have to TURN OFF PEDAL ASSIST mode. When you start peddling, the bike might automatically put the controller into Pedal Assist Mode causing your Error Code and limiting your controller to 20mph etc. Keep up the Goat work ; O )

Do you have to upgrade the battery with the controller or ca. You run a 90v controller with the 72v batteries?

so you only changed the motor what about the battery..your using stock battery?? or batterys...

[@MiamiEBenz]

I meant the controller not the motor..lol

[@maximumchargeEV]

Changed the controller and running two batteries in parallel to get more current. One of the batteries is stock.

[@mkeonine]

I think I'm prepared to purchase the frame battery. Is it really only around 30 lbs compared to the 52 lbs Goat offering. That's a drastic difference imo. The weight savings plus it's for certain Samsung cells make it easy for me to go Northeast I think. I'm just kinda perplexed why majority Goat owners from the Facebook group go the Goat option more?..

[@maximumchargeEV]

I think it's a trust and brand issue. Kevin from NE Batt Sys isn't as popular or as big of a company as goat so the name isn't as "out there". The high quality cells are a huge plus from his battery, I have no fears ever of overdrawing from this battery. I've actually been working on this bike recently and should have it fully done before the year is over.

[@IMBruceECLECTIC]

Why is motor silent?

[@maximumchargeEV]

that's a good question, but the answer is above my pay grade.

[@housedjnyc]

If you want even more flexibility and speed, switch over to a Fardriver controller. My build will consist of a QS273 8kw, 72v Molicel battery, & a Fardriver ND961800 track version controller, which can pull 1350 line amps and push 1800 phase amps. The bonus of such an over build is a massive increase in efficiency in addition to high speed. A 72v system with a quality uses less energy at 30mph than a 48v system. And voltage sag is also practically eliminated on a high voltage system. Or, if you don’t want that high of power, you can always slap on a front motor & additional controller for some awd grip…

[@robtval]

Where are you getting your parts from? Does anyone live in the San Francisco bay are that would be able to do an upgrade on my motor goat

[@Guitarman007]

Anybody know if there's a better aftermarket seat for this? The stock seat is a bit too squishy flat for me. I need a bit more cushion.

[@maximumchargeEV]

i've been looking around for one myself.

[@marvinlewis1879]

Hey there, Alex, Would it seem to be easy to do a plug and play if we took the 110a fardriver controller from the Hulk Goat and plug into the Motor Goat? Of course, this will allow a 72v battery for even more power. Not to mention, I think the controller is wired for all stock accessories.

[@maximumchargeEV]

Probably won't be easy or plug and play

[@marvinlewis1879]

The research continues. If I find something prominent, I'll let you know

[@wcrcp24]

can youy do a upgrade video on the ride1up revv1?

[@maximumchargeEV]

I don't own that bike and unfortunately don't have the time to mod one if I did! I wish!

[@EBikeBuilder_]

careful with the FW - if you give it 10 amps. It'll be doing normal amps + 10 amps. You lose a bit of torque with FW. So FW might increase the high end top speed, but its a matter of whether the torque is still there to reach that speed. There is a sweet spot for FW that you can find. I think how Justin at grin tech says to set it up, is to measure the unloaded wheel power draw (full throttle/off ground), increase FW, measure power draw, etc, if you plot the unloaded wheel power draw and FW amps on a graph, there will be some point where increased FW starts to increase the power draw and create diminishing returns.

[@maximumchargeEV]

Oh yeah I figured 90 amps + 10 amps of FW = 100amps total for the max output of the controller. SO the FW decreased torque even at lower RPM? I would have assumed that the software turns it on only at higher speeds.

[@simms196]

Are you using stock display & motor with the new controller? This is very interesting!

[@maximumchargeEV]

stock motor, new display.

[@coachnate1]

I have the same bike and would like to switch to a single speed like your bike, do you have a video of how you did it, thinking about swaping the controller as well...ordered a battery from northeast batterey for my wife's biketrx and couldn't be happier so thanks for letting us know about them. Nate🤙🏽

[@maximumchargeEV]

nice! I actually couldn't find the spacer for the single speed gear so I just have the freewheel on and the chain is on the smallest sprocket with the chain tensioner on. Believe it or not I'm going to be adding a shifter becuase when I'm on slow moving trails I want to pedal and have it do something to "blend in" better with other bikes

[@robtval]

whats the name of the controller?Part number and where to order this controller

[@maximumchargeEV]

risunmotor sells this. It's the sabvoton 72100 100 amp programmable controller.

[@wr3ncher]

The over current error codes are “normal” with prolonged high speed riding. If you burn thru the battery, pull over, shut it down like 5 minutes. It will regain voltage

How many amps is battery capable of putting out that the key to power. That tank battery based on my calculations can only do 125amp output max. The BMS on the second battery is only 60 A you will never be able to use the full capabilities of that controller. You need a higher amp producing battery. Something that at least can produce 150 to 200 A in my opinion. Plus the ballot battery blender only allow you to do 80 the top battery probably got to BMS. That’s stopping it at 60 or 80 so the set up is not even able to pull from the batteries enough power.

[@maximumchargeEV]

good question. The tank battery can output a nominal 50 amps, and the larger battery can do more, mine is set to 80 amps, but could probably handle more. since the bottom battery is 2x the size it will do more work when run in parallel with the smaller battery. so for example, the bottom battery will give 60 amps, and the top battery will give 30, maxing out the 100amp controller I have installed, while also not stressing out either battery. The blender is rated for 120 amps, but I will be removing that element in the next revision.

[@FloridaVolts]

@@maximumchargeEV according to the data sheet on 60v25ah Samsung should be able to take 125amp output I saw your face book post. It is. A good idea to upgrade the BMS in tank battery to a 80-100 amp BMS it should be and easy upgrade to plug in play new bms. There’s nothing wrong with the VMS that power goes use. I think they only put a 50 amp BMS just so the pack won’t overheat. And last longer
