What is the advantage of this over insurance? This is $90 plus $4 a month for service. When I looked at insurance it was $8 a month. I guess after the  first year, which is about the same, the GPS is 4 a month vs $8. But the $8 will fully replace the bike at 100% cost.

I wanted to share my install. I still haven't removed the stock controller due to difficulties. Also need to get some black zip ties. However, by installing in this location, I didn't need to use an extension cable. I also did additional testing over the weekend and messing with the settings I can't seem to get beyond 25.4 mph. This is just cranking the throttle while on kick stand. Changing tire size is pretty much the same except if you change to 29ers. Then it actually jumped to 27ish. Which is odd. I didn't ride it on smaller tires with my phone speed to see if I could actually get it to go faster. I had limited time. 

It's on the bottom of page 36 - 38 in the doc.

CD8 instrument L parameter definition
1. L1 parameters are applicable to the automatic under voltage controller. The
default of the factory L1 is 0.
1.1 L1=0, the automatic undervoltage controller can automatically select the under
voltage value according to the battery voltage.
1.2 L1=1, the undervoltage value of the automatic undervoltage controller is confirmed to be 20V.
1.3 L1 = 2, the under-voltage value of the automatic under-voltage controller is forcibly confirmed to be 30V.
1.4 L1 = 3, the under-voltage value of the automatic under-voltage controller is forcibly confirmed to be 

L2 parameter is suitable for the super high speed motor controller. The default of the factory L2 is 0.
When the parameter P1 parameter is greater than 255, the L2 parameter is enabled. Combined with P1
2.1 L2=0, the P1 parameter is set as the calculated value.
2.2 L2=1, the P1 parameter is set as the 1/2 of the calculated value.

L3 parameter is applicable to the dual mode controller. The default of the factory L3 is 1.
3.1 L3=0, the controller only uses the no Holzer mode when the motor Holzer fails.
3.2 L3=1, dual mode controller selects operation mode according to system optimization.

Ok. C5 Deff impacts the max power the DD motor will put out. Oddly, going up in C5 values does not increase the max wattage. However, C5 00,01,02 will in the 1400's watts whereas C5 10 does not. (At least for me). Give it a try and let me know your results. Obviously it doesn't stay at this power nor would you want it to however it does seem to make it more zippy. Wife called me in so I guess that is all for now.

According to the manual I have, C5 settings are... SEE ATTACHED as I cannot seem to figure out how to insert an image.  was much easier on iPhone, now on computer...

C5 settings are for controlling the maximum operating current.

C5 Setting
===================
00 --> 02  UNDEFINED
03 = Max Current Value / 2.00
04 = Max Current Value / 1.50
05 = Max Current Value / 1.33
06 = Max Current Value / 1.25
07 = Max Current Value / 1.20
08 = Max Current Value / 1.15
09 = Max Current Value / 1.10
10 = Max Current Value

Thus lowering the value should limit the max current to motor with 03 being the lowest valid value.

C5 00-02 settings are only undefined in the non color controller. The Bolton ebike guy even says this in his video. But doesn't go over them for the color version. Attached are the defined values... whatever the heck they mean. I do get more power when using below 03 compared to 10 which is max power. Wish we knew what made it ride faster. I can ride 20 mph and only use 300 watts. So it should deff be able to go faster.  I deff think using higher power will decrease the life of the motor which I am ok with. Hopefully Bolton Ebikes will have the motor upgrade you mentioned. When C5 is set to 00-02, it will get to 1470 watts but only briefly, and the quickly declines.

I don't think it's your weight holding back your max mph since I am maxing out the bike and getting the same.

Sorry. Decreasing max speed didn't make me go faster. Using the stock controller allowed me to go faster. This is why I think there is a setting or two wrong to allow the additional speed. I can't hit 25 mph on the new controller and was able to on stock. I am going to play a bit with some settings today to see if anything changes. Below is, most likely,  the link to the motor being used. I suspect there is some kind of amp limiter in the device. 35x48=1680 watts which I defy haven't seen. I am talking about adjustment of the C5 value here. This current limiter is prob the hard limit you are talking about before you are just trying to push more but instead just wasting battery power. Here's what I think is going on. When C5 is set too high, the controller is displaying higher watts and trying to send more power to the motor but is being limited by the current limiter in the motor. Power is voltage x current. I question if the voltage supplied to the motor is max avail and wonder if it current applied could be exceeded before the max power is reached if C5 is too high. Maybe an example would help....750 watts could be 15 amp x 48 volts. Or could be say, 16 amps x 45 volts. Or 18.75 amps x 40 volts. All of these equal 750 watts. However, say, the motor has a current limiter of say 15 amps., then in the last case, the controller is trying to push 750 watts, but being current limited to 15 and the motor is really only pushing 600 watts when it could push more. So adjusting C5 to a lower value could prioritize the controller to push more voltage to the motor vs current and perhaps actually giving more overall power... Just a thought.

I HAVE NO IDEA WHAT THE "L" SETTINGS DO SO I LEFT THEM AS THEY WERE FROM BOLTON BIKES.  If anyone knows, please share.



Here is the full manual including the L settings. Might help you also dig deeper into settings.

Hmm... it's interesting your P2 is 5 for proper speed and I found mine to be 1 to be correct. I think C5 diff needs adjusted. I seem to be running into some kind of limiter other than P1 and it might be associated with P5. With stock, I was able to go above 25 mph once I increase the min speed to 40. However, with P1 set to max, my speeds limits to 21-22 and this is at less than 400 watts. I thought it was my battery and when fully charged I am getting the same results. I'll check out your other settings and test again tomorrow. With this now being the warm season, it will give us more chances to play with the settings. Also, did you have any luck getting the stock controller off? I actually still haven't taken mine off. I installed the new controller below the stock on and secured with zip ties. Looks odd but works just fine. Also installing it here doesn't require the extender. At some point, I want to take off the old one and use brackets like I believe you are using. Or it might have been someone else. Just need to figure out where to get them. I'll figure it out out of season. Right now, I just want to enjoy the ride.

I just installed my kit a few days ago. Curious if you figured out what settings you liked. Do you feel like you have dialed it in yet? Still trying to get my P2 correct for proper speed. 4/5/6 do not work. Still need to test out the others. Glad I found your post. Looking forward to your reply.
