Yeah when I would be going 45 or 50 it would be on smooth roads. If I ever get it off road it would be slow speed and by off road I mean the occasional two track or field. Probably nothing super gnarly. Brakes really are my only concern at with the bike parts. I have a set of 203mm rotors I...

Well after a little more research I see that some people are hitting 40-45 mph with the cyclone on some lighter bikes using only 52 volts. I suspect that with 72 volts my 45-50mph goal should not be too far out of reach. I think I am going to step up the battery to approximately 20AH but...

So late in 2015 I wrapped up version 1.0 of my 2wd electric bicycle. This year I have decided to revamp that bike to make it a little more tidy. I have about wrapped up that build. Anyway I will be riding that bike around for a bit but I have decided that I want to build a new bike. This...

Well. As I suspected, it was nothing more than the motor itself acting on the pickup. I moved the pickup and magnet away from the center of the wheel and everything works as it should. Problem solved.

I believe each item serves its own separate function. I did take not of a few things. For starters I have the sensor on the rear wheel. There is a motor in the rear wheel as well. I can have the controller on for the rear motor and the assist level set to zero and the speedo will read...

I finally got my bike on the road and I wanted to up date this thread about my switch. So essentially I just put a switch in one of the lines that runs between a thermo switch mounted on the battery and the BMS. In theory this should have worked. However if I hit the switch to turn it off...

I have a S12S controller with the LCD 3 display and PAS only While pedaling the speedometer goes crazy. It jumps all over and goes as high as 50 mph. As soon as I stop pedaling and coast the jumping stops and it reads the speed as it should. Anyone have any ideas what might be causing this?

I bought one of their cheaper packs and tore it open to add a master kill switch. It all seemed legit. Proper quality cells, proper wire routing and a quality bms. Until I start building my own packs they will be my go to vendor for battery packs. Also even when I start building my own packs I...

I put it all on the non drive side and it would only work pedaling backward. I also tried flipping the disk on both side and it did nothing. All tests were with the disk 1-2mm away from the sensor.

Well magically I played with it again and it all works just fine. For anyone that cares, the part of the sensor that forms a point points to the back of the bike if it is on top for the bottom bracket. Then the exposed magnets face the sensor. All of this is mounted on the drive side. I...

The PAS I have is listed in my first post. I know I had it in level 3 or higher. I am also pretty sure that I tried every combo but i will tinker with it some more. I will also check out the wires and see if all that checks out.

I do not have the crank or PAS mounted yet. I tested it as suggested while off the bike. I am running thw S12S controller

Well I have managed to get my motor to spin with the throttle but I am not getting anything from the PAS. All of my setting appear to be correct but I get nothing no matter which direction I go or side I use.

Ok I have my wiring sorted and am entering in the info on the S-LCD3 Display. I am to the point where I need to do the math to enter the info in P1 (Motor Characteristic Setting Mode). As some of you know the formula to give you the number for this entry is as follows: P1 = motor gear...

This pic may help illustrate how it is held in place. I have had the sensor installed on both sides and it seems to mount just fine. After I do my test (still messing with wiring) I am hoping to mount it on the drive side so it is hidden better
