sw900 lcd display manual in stock

I found a complete motor conversion kit for only $469. That does not include a battery but I already have a few batteries so $469 was an attractive deal. Of course, it comes from China and there are no helpful instructions that are provided. Installing it was not a problem but getting it to work without instructions was quite challenging. Fortunately I was able to find instructions online which was a big help. I got it running but the top speed was quite slow. I was ready to send it back for a refund when I sort of accidentally stumbled across the problem and got it resolved. If only the Chinese would include instructions all of this could have been avoided.  For what it is worth, I just now found one user manual which covers what the problem was and why I wasn’t getting much speed or power out of this new motor. Anyway, I am writing this article in hopes it will help others in getting their self installed e-motor system up and running.

My new system uses the LCD-SW900 display console controller which is a common display console controller various e-motor manufacturers use. I did not use the cadence assist hardware component in my installation. I may install it sometime in the future. I only have a manual thumb throttle hooked up. Upon completing the installation using a 48 volt battery (this motor is made for 72 volts) my top speed was only 5.6 mph and had no torque available at all to climb the slightest incline. I rode it that way for a couple of days.That is a mighty slow ride but still better than I can do on my own without any e-motor assist. About 2/3 of the way into my second day of riding so slowly I just happened to discover the answer to more speed and power. I pushed the UP ARROW button on the 3 button control which caused it to go from power level one to power level two. (PAS — power assist — level is displayed at bottom left corner of SW900 display) Simple enough but without any knowledge and understanding of how it works … well … I was stuck at 5.6 mph as when first turning the system on PAS 1 is what it starts out in by default. If only they had provided instructions. Anyway, I knew that 5 levels of e-motor assist were programmed into the SW900 display console controller so I continued to press the UP ARROW button watching it change up to assist level 5 and experiencing more speed and power with each level of increase. Hallelujah! ! Happy days are here again! Definitely this is the most powerful e-motor I have had installed yet. It is not as fast top speed as my former e-motor but I am really liking it as it is whisper quiet and far more powerful. I am tempted to buy a 72 volt battery just to see if this motor will perform as advertised … about 45 mph top speed. I am nearly 76 years old and probably should avoid the temptation as I would likely find myself careening off of a tree unless I wrapped myself around it. BTW, to go down in the assist level pushing the DOWN ARROW button lowers it one level at a time. Turning power on and off is accomplished by holding the middle button down a few seconds. So if you find yourself in the same situation I was in hopefully this will help you.

Even though you can see onlysix (6) main readings on the display, there isfourteen (14) usable functionsyou can access and adjust based on your needs.

Po2 – Km or miles per hour:depending on your location, you can select to display the speed in km (“0” ) or mph (“1”). For this to work properly, you need to set the size of your ebike wheels.

Po3 – Voltage of battery and motor:this is where you will specify the volts of your battery and motor. You can select 24v, 36v and 48v. Normally, the SW900 is set to 36v so make sure you select the right voltage grade.

Po4 – Display sleep mode:this come from zero to 60 mins. In this case, zero means your controller will stay on all the time and if 60 mins, it will shut down after 1 hr of no operation (this will not happen if you are riding your electric bike though).

P06 – Wheel size selection:this is where you establish the size of your wheels in inchs. This is important in order to display the right speed you are traveling.

When doing my research on what controller was ideal for my ebike, I thought, should I get a very simple controller or a more sophisticated but complex LCD display that can give me more riding features?

When something is not working well with your electric bike, the SW900 LCD can inform you about the issue or system errors. This is what you need to know:

I believe the SW900 LCD is one of the most functional controller for e-bikes in the market but from my perspective, if you don’t want to have to much of a headache, just stay away from it and install a most simple one, like the ones provided by Bosch.
