- Here's a video on changing the settings on the Ecotric bikes with the S900 display. Including how to set the max top speed.
See pined comment from Fremmy below for full settings. (thanks Fremmy)
Options are:
1 - The display light
2- MPH or KmH
3 - Battery voltage
4 - Screen timeout
5 - Number of PAS steps (0=3, 1=5, 2=9)
6 - Wheel size
7- Maximum speed listed in KM.
8-12 ??? Please let me know in the comments if you know.
P01: Backlight Brightness (1: darkest; 3: brightest)
P02: Mileage Unit (0: KM; 1: MILE)
P03: Voltage Class: 24V (default) /36V / 48V
P04: Hibernation Time (0: never, other figures refer to the hibernation time)
Unit: minute
P05: Power Gear - 0/3 Gear Mode: Gear 1: 2V Gear 2: 3V Gear 3: 4V 1/5

P06: Wheel Diameter Unit: inch Precision: 0.1
P07: Magnet Steel Number for Speed Test Range: 1-100
P08: Speed Limit
Range: 0-50km/h, parameter 50 indicates no speed limit.
1. Non-communications status (panel-controlled)
When the current speed exceeds the speed limit, the PWM output will
be shut down; when the current speed falls to lower than the speed limit, the
PWM output will be activated and the driving speed will be set as the current
speed ±1km/h (only applies to assist power speed, not applicable to the
handlebar speed).
2. Communications status (controller-controlled)
The driving speed will be kept constant as the limited value.
Error Value: ±1km/h (applicable to both the assist power/handlebar
speed)
Note: The above-mentioned values are measured by metric unit
(kilometers). When the measuring unit is switched to imperial unit (mile), the
speed value displayed on the panel will be automatically switched to corresponding imperial unit, however the speed limit value in the imperial unit
interface won’t change accordingly.
P09: Zero / Non-zero Start Setting:
c. Zero Start
d. Non-zero Start
P10:
Drive Mode Setting
3.4 Power Drive - The specific gear of the assist drive decides
the assist power value. In this status the handlebar does not work.
3.5 Electric Drive - The vehicle is driven by the handlebar. In
this status the power gear does not work.
3.6 Power Drive + Electric Drive - Electric drive does not work in
zerostart
status.
P12: Assist Power Intensity Range: 0-5
P13: Power Magnet Steel Number: 5 / 8 / 12pcs

P16: ODO Zero-Out: Long press the upper key for 5 seconds and ODO will zero
out.
P17: Power choice function from 250W-1000W.
This is the s900 settings and what they mean.
Fremmy will the bike go faster by adjusting P08?
@@perezr1020 depends if you're battery is 48v or 36v. My bike has a 36v battery and motor and I saw an increase from 25 km/h to a maximum of 31-ish. Unless you have a 48v battery and motor, you probably wont be able to get 35 km/h or higher unless you actually pedal a lot yourself.
Fremmy Pls, can you guide me through the process on how to engage the Cruise Control while riding? Thanks & stay safe.
@@folaogun I haven't messed with it, all I know is: If you are standing still, sitting on the bike, and then hold the down button, it will engage cruise control, however, in my case it only cruises at 6km/h which is not sufficient enough for me. I have no idea how to change the cruise speed. To turn off the cruise controll all you do is hold the down button again until it turns itself off, or you can turn off the system by holding the middle button if the down button doesn't work.
3 years later and this still applies to my new Cheetah 20 model. Thanks!
I rarely give reviews, but I have had this bike for 1 week and it has been Awesome! BUY IT!
Thanks for your video is the way to get the happy riding 🙏
Hi. Have same s900 and have tried extensively to get all programing settings and meanings from the company to no avail. If you get any more info please post.
Thanx for the video. They had my p10 set to 100 and the bike would shut off in the middle of a ride. So I set it to 200 and it worked. So when you went through the settings I saw yours at 200 which helped. I also have a 48v, mine is a fat tire.
Thx again
Thank you, just boosted the speed on mine, very impressed.
Does the increase speed setting work on any bike?
Thank you. Appreciate the video
@Fremmy can I cancel pedal assistant and only pedal and when needed use the throttle ?
I don't see the voltage options on the P03. Appears from 0 to 60. And other parameters are different too. Please, you can help me. I need the description of the parameters. It's the S900 but it looks like another software version
Fantastic mate 😊👌
hello thank you for your video. the p14 parameter on my sw900 goes up to 50 A. I have the impression that it is there but inactive because setting it to 1 or 50 does not change anything in torque or speed. possible in your opinion?
I have this controller and your review is about the same as my knowledge of it. I have seen the SW 900 videos and the settings are the same with a few exceptions. The biggest exception is the WATTAGE display in the bottom of the display. The S 900 does not display wattage, the SW 900 does display wattage. The S 900 is a lesser version of the SW 900 controller. Hope this helps...Please comment if you have other info on this controller and display.
Thanks, I was wondering if there was an issue with my LCD unit because the wattage was not displaying on my S900. Now I know otherwise.
How do I get replacement bearings and all that go into front rim
I have the same bike which is 36v. Did you upgrade your battery to a 48v? Realized that changing this mode doesn’t work considering it’s a 36v battery on the bike.
Will under volting a 48v increase the distance when riding?
Thanks for explanation. Trying to figure out what I consider a problem: My power assist on a 48V 500W geared rear hub motor eBike I recently purchased in Costa Rica : My new eBike takes off at almost full power in PAS #1 (a bit dangerours to lend out on my funcky dirt road), while the watts meter jumps between 750+W to 200 W. The seller informed me after my paypal purchase with delivery, and then expression of concern; that my eBike was modified for Costa Rica and hills, and I could get by on PAS 0, and just use the throttle. My recent review of settings reveal (P14) Max Amps was set to 22, which produces twice the watt rating for a 48V 500W motor. I think that does give the motor more power; & testing on hills has not heated up the motor or 22 amp max controller to my finger touch. I hope experimenting with my settings will get me back to normal PAS modes and a properly working watt meter. ... I DO NOT Appreciate this unexpectedly new learning curve. I trusted the shop I purchased from to dial in everything before shipping, and inherited some loose ends to chase down. Still looks like a decent deal for the price, but wondering about longevity at 48 V x 22 AMPS = 1056 WATTS on a 500 Watt motor.
Hello,
Did you manage to tinker the settings for your issue? I am having the same problem with my 48v 1000W. The seller (Violamart) is string me around without providing any instructions for the right settings because they have no idea either. They are just the middle man.
My PAS goes on full power at level 1. It ignores the levels changing up because it is already riding at max PAS level even though the LCD shows PAS level 1. If I connect the speed limiter wires of control box, the PAS is always working on level 1 and ignoring the changing of levels. I've tested with different hub motors, different battery, different controllers, different PAS sensors and different LCDs. My conclusion is it's the LCD because both LCDs I have tried gave got the same settings. Either that or both controllers I've got have bad programming (both are from Violamart).
Although, another kit I bought from them a year ago worked perfectly fine. Shame, an accident destroyed that bike's controller.
Please let me know if you've figured out the right settings on the LCD. Thanks
@@RogueLegend999 yo kushan. I learn tinkering w LCD settings could not fix. eBike shop later told me my eBike had been modified for hills. I read w more knowledge and software in PC ... One could adjust parameters, but that is beyond me. I got eBike builder to say he would fix my concern when he got a new round of inventory. He forwarded my complaint to manufacture supplier who said they would soften PAS #1 #2. Learning Curve reveals: Not all eBike function like my RadRover which I love riding way more than this eBike I purchased in Costa Rica.
@@CaptBill69 my 1000w was working at 1200w on PAS level 1. I managed to bring it down to 500W by changing the current (amps) in LCD settings (P14) to 17. Th throttle is kind of useless now because it is working at around 400W. But atleast I've got my PAS levels increasing power graduallly as its supposed to.
Running a 500w motor at 1000w will damage / burn out the motor.
P07 is actually the magnet pairs in the motor. For direct drive it is usually 46, and for geared hub motors it is usually 86 .
What happens if I get this wrong. I cant find any reference about how many mags on a Himiway.
@@dozukime I also would like that answer
Thank you!
What bikes use sw900 and what’s the difference
Hi , I don't have the option for p07.. any help ?
Good afternoon you can help me with this problem does not turn the rim and on the screen be error error please
Actually would like to know what 8,9,10 and 11 do, please? the pinned comment by Fremmy does not address the S900.
How do I get a print out of the seventeen changes on the nine hundred
Hello ebikes, how to turn off cruise control permanent
S900?
My LCD backlight doesn’t turn on does anybody know how to fix it?
P10 is magnet count on how fast you want the pedal assist to kick in 100 is 1 revolution of crank 200 is two revolutions because there is a 100 magnets in motor I keep mine at 100 the quickest activation of pedal assist
Thanks...
On P03, will putting it to 48V increase speed? Battery life goes down significantly so I leave it on 36V.
I noticed mine too.. and didn't do good up my hill at 45.. p03 should be at 48v of your battery is 48
So, What does P10 do?
On my s900 i have only 16 params. And i can't see speed (zero) if i stop push throttle. How to fix?
Re: the tire size, I have an e-trike back tires are 20". The motor is on the front tire which is 24". Should I set it for a 24" or average it out? Suggestions?
I know it's very late, but maybe it will still help (someone). The tire size setting is really only to get the correct speed and distance measurements, so set the tire size to whatever the motor tire size is. In the above scenario that would be 24".
Hi!
You plugged the usb charger of iphone to the LCD S900?
You can but the charging is so low, for instance even with my phone off It would charge 5% of the phones battery per hour. So the Mah on the usb are very low. Most likely because it causes energy bleeding, killing off the battery faster.
After you change to km from mph and tire size. Does that still give you an accurate distance reading?
WOW 👌👌👌👌👌
Very helpuf, thanks. I don't understand what you mean by chaning the power assist steps. what are steps? how long it keeps going after you stop pedaling? or something else? Thanks!
Oh hey!
That's how many steps you take on the pedals before the electric motor cuts in. Leave it at the minimum, 3 steps in 3rd gear will help scoot you across an intersection before you start irritating people in traffic. These bikes are so heavy, they can't get out of their own way without power assist.
It’s the number of speeds of assist or throttle settings 5 steps means level 1=4mph, 2=8mph, 3=12, 4=16, 5=20. 9 steps means level 1=2.1mph, 2=4.2 on up through level 9=20 mph.
Hshtug I like it
What the lighting cable for? Charge phone?
Yes
how to find go city bike controller reset settings..
I have a s900 display and every setting I see on her don’t apply to mines I can’t get setting for Throttle assistance
So I set mine to 45 in p7 and got it to 25mph but some people say if I unplugged the governor that will change the speed is that true?anyone
So, the up and down keys on mine tend to respond only every other week or so. You don't happen to know if you can program this to start in the power-mode rather than the eco-mode?
Hi! How to increase the speed limit?
Watch the video u mong
I don't have the P0 7 option on mine...
Must be an updated version of the S900. I don’t have the usb plug at the bottom of mine.
How do you get the trip not to reset. If the display turns off my bike’s trip resets?
yup
Keep the display on all the time.
Set P04 to 0 and it will stay on till you remove the battery, or turn the key off, or push the middle bottom for 3+ seconds. This might be a problem, having to leave the key in if you leave the bike unattended. In that case, note the time on the display and add it to the time at the end of your ride, if it's that important to you.
How can I leave pedal assist off and use throttle only?
Go to P10 on your lcd There are three options 0 is to ride with a pas only 1 is for throttle only and 2 is for a combination of PAS and throttle hope that helps
@@jamie1x2 that's for the sw900, not the s900
How do you charge S900 with usb cable ?
you dont. the cable charges his phone from bike
If you increase P14 Amp, wouldn't that increase the torque?
Yes but it can be dangerous if you don't know what you're doing.
Do you know how to do a factory reset?
manual says go to 11 and hold up and down for a few seconds
I think 11 is for uping the amps on the controller wich ups the power!! Volts x amps equals watts power that gives the true watt power your running. Maybe that company blocked it from adjustment or seeing how much it is.
It’s to reset to factory settings. Just hold down on the up button until it resets
Guys , help please
While I'm riding without electricity the computer doesn't show my speed . It starts showing only I use 1-5 or just electricity power .Does Somebody know some about that ?
The s900 and sw900 get their speed signal from a speed sensor inside the hub motor. It is a 6th wire that is passedx along with the hall sensor wires.
If you have a geared hub motor like me, the motor magnets don't spin when coasting due to the freewheel mechanism. This means the motors speed sensor which pics up the magnets passing by only works while pedaling. I plan on buying a separate speedometer with a magnet on the spokes because it annoys me.
hola soy de peru no se si me puedes ayudar, tengo la pantalla S900 en los ajustes P03 que son voltaje 24 36 y 48 en esta pantalla sale desde el numero 0 al 60 no se porque, debería tener 3 opcione la de 24 36 y 48 no la tiene, por favor si me puedes dar una sugerencia
Yo también tengo esa pantalla parece que tienen diferente software pues el mío tiene 23 programas,lograste encontrar info o el manual? Soy de peru

Yo tambien tengo ese problema. Encontraste la solución o un manual?
Does you know how to select the 'Walk' mode?
Hold Up arrow and down arrow and it will start walking and release them to stop the bike
You hold the down arrow
I just learned that whatever speed your going, while your on the bike hit the down arrow and hold it and it acts as a cruise control
On my Ecotric 20" Fat Tire Folder, any time you press the "down" button and keep it pressed, the bike will be in WALK mode, even if your going fast, the motor will slow to walk mode
@@philipmorrill7147 found it .Thanks
I'm disappointed I can't set cruse control on my s900. I walk my dogs with the bike and it's hard to keep it steady with a throttle. Pedal assist goes too fast for a general walk.
Might or might not help there is a 6 mph walk mode on the bike it comes in handy when your going walking speed with the dogs I believe you hold the down arrow while at a complete stop and then to stop the 6 mph walk mode you just have to use the breaks to cancel
@@jamie1x2 Thank you for the suggestion. I will try that. I love the bike.
@@renate19861958 you are more than welcome happy riding
@@renate19861958 just turn the throttle at desired cruise speed then at same time press and hold the down button for a few sec to activate, touch brakes to deactivate.
@@-meganeura Oh thank you so much, good to know.
my SW900 i am have error 10 what is this?
Motor hall sensor error
please find the plug that connects the controller and the motor , please re-plug it , maybe the connection is loose
(This is what the manual says) good luck
can I use 48 Volt battery for that Rocket Bike?
motor will handle it. May need display and 48v motor controller
don’t raise the speed it will short your controller it’s suppose to stay at 36v
I think mine felt weaker going up my hill.. im putting it back.. thanks
hello
why on mine the max speed i see only 41 ? how i can increase it please? its sw900 lcd
air up and your tires to max pressure and set po 7 to 46 and po 8 to 100 in kmh this works for 72 volt 5000 watt
Increasing the tire size will make it faster
Where do u get a bigger tire?
@@rentedduckliing you don't. Just increase the tire size on the lcd screen to trick the motor into working harder by thinking the tires are bigger which would make it go faster....
Explain more I’m very intrigued
@@Mix0322 Actually it is the OPPOSITE from what the other poster stated. If you set the display to a SMALLER tire size, the controller will be “tricked” into thinking it must rotate the wheel at a faster rate to achieve the top speed setting (e.g., 20 mph). So when your speedometer reads 20 mph (at which point the motor kicks out) the wheels will be spinning FASTER than they were originally and your bike will actually be traveling faster than 20 mph. Note that by changing to a smaller wheel size setting, the reading on the speedometer will no longer accurately reflect the speed at which the bike is traveling - you will be riding FASTER than the speedometer indicates. Note: DO NOT set the max speed at 45kph as the UA-camr recommends. Keep it at 35. The 45 setting is used by factory staff to QC the motor. Running the bike with the controller set at 45 for too long a period will fry the controller. I know that for a fact as I just picked my bike from being repaired and had a long discussion with the Ecotric technician about the “dos” and “don’ts.” I learned my lesson the hard way! Best luck!
@@sonnycostello5887 okay so then at 35kph will it only go 20
11 is a factory reset if you hold up on 11
Is 11 a factory reset on the sw900
08 = Max 50MPH yet another modification has to be made. Blue Wire Disconnect.
09 = Zero Start or Non Zero Start.
