This is the best video I found yet

[@MrEdmundoGC]

what happens if i change the factory 12 amps to 18apms, i feel it gives more torque to the motor. after 10 mins everything seems normal nothing warms up

[@mostafamansour1099]

Did anyone advise you regarding cuz I wanna know myself 😅

[@MrEdmundoGC]

@@mostafamansour1099 you notice a difference in torque and speed , depending on your controller and cable from the fases(blue,yellow, and withe) check the cable thickness they might support 20-25amps, ir it's more than 30 amps they might burn the cable (in my case with the cables my ebike brought)

[@karenbiddle4824]

does anyone know how to do a factory reset on my gogo best gf 600 e mountain bike or what each setting should be on some one at work thougt it funny to change it please

[@MickyBee73]

For "Cruise control" when riding along get to your desired speed to cruise (must be above i think 10mph or so) and then... Hold the "Down" button for approx 5 seconds - You can now cruise at your chosen speed, it's great 👍😀 Cruise control will stop when you either move the throttle/throttle lever, or if you press either of your brakes. Walk Mode - Press and hold the "Down" button for approx 3-5 seconds. You can now walk alongside your bike and it will power itself as you walk with it (it helps if you keep hold of the bike 😅). Headlight ON/OFF - Hold "Up" button for approx 5 seconds, this turns your light on, hold it again for 5 secs it turns it OFF. To cycle through "max speed/battery current voltage/average speed/timer" press both together "UP" & "M" (middle button), pressing UP&M again will cycle onto the next of these 3 things - to go back to normal display press and hold "UP" & "DOWN" together. NOTE - My SW900 is a 2024 model, but these will probably work on any years model.

[@williamreyes27125khz]

You could also maintain any throttle setting for 5 seconds and it will hold it there until you speed up or apply brakes.

[@DavidMullettMoofy]

Hey only like the first one or two settings work and then when I try to go up or down it won't click anywhere and do anything

I have a 500w 36v kit but i have the same sw900 controller which is set to 12 amps also but 12x36 =432 watts. Should i just increase it to 14amps to get 504 watts? My battery is a 17ah battery if that makes any difference.

[@louispconstant6624]

You don't need to pedal that fast, that's the whole point of assist. The bike will still go the 23mph if you pedal slower

Make the wheel size from 27.5 to 17 . And set the pas from 3 to 5 modes . After that you can ride 34 kmh :)

[@HaroldJackson]

I haven't run into that. I would order a new one.

[@dennisonicc]

Setting number 15 is actually cutoff voltage. This is from the original SW900 manual. The manual presented in this video appears to be an outdated or wrongly copied one.

Get a big voltage battey for more speed. This setup can handle 60v easily

[@demusmarcus8240]

@@vincenzotatti3325 can I just add a 60v battery to my 48v bike

[@Just-A-Guy-Learning]

Turn the current setting up. Also shunt mod. Can get nearly 3000w out of a stock 1000w controller. Just be careful on hills. And don't stay at max throttle constantly. Once you get to max speed you can pin the throttle and no harm will happen. Because amp draw decreases significantly. It's when accelerating or climbing hills that you need to be careful how much current you draw. Can cook the motor or your controller adding solder to the shunts increases current. The more solder you add the more current you get. My display allowed me to set my current to 30 or 32a. I can't remember the exact number. Top speed of 35mph and 1400w constantly from a 1000w controller. Shunt modding allowed me to pull 2900w. I had to use an external watt meter. Once you add solder to the shunts the stock display no longer reads the watts/current accurately.

[@Just-A-Guy-Learning]

After the mod my top speed was closer to 45mph. 26 inch wheel. I'm actually repurposing an ebike motor to make a home made euc. Using a vesc controller. Im switching my ebike to a vesc controller as well. The flipsky 75100 aluminum pcb controller. Can do 20s at 100Amps. It also does field weakening and foc. Not a bad 120.00 investment.

My SW900 gives a breakproblem. The brakes are fine, but the motor doesn’t work because of the fact the the display doesn’t reset itself. Is there a way to reset the display? Thanks for the answer. I really like the explenation films. Greetings from the Netherlands 👍

[@HaroldJackson]

It should reset if you remove the battery. The brake problem could be the hub motor. It has a built-in brake in some motors. Good luck. Thanks for watching and have an Awesome day.

[@ancientsounds6989]

Just because the brakes work doesn’t mean there’s a problem with the motor it could be that you need to calibrate the rear brake to the motor so that it will cutoff the motor when you brake

I can say that works only on specific controller and display. Some controller has password set up and even if you have password they programmed to have specific limit that will not make bike faster . Those setting are set for liability as some countries has restriction on max speed. I would not recommend to mess around as it can damage battery or motor and controller. Stay safe !
