No smooth ramp up on Lyen controller, just one big hit of max amps. Very twitchy and dangerous on powerful bike. I think there is a way to make a throttle tamer but I have never tried. It is well documented on the forum. I think a Cycle analyst v3 can tame throttle. It can be done by using ‘current’ throttle settings in CA v2.3 as well. If you look up the manual for a CA v2.3. It will show youmaitilupas wrote: ↑Mar 22, 2018 8:11 amthan should I try this ? i want fast throttle but also want a smooth ramp

Re: LMX P2 : Freeride trials motorcycle frame development
i red before about that throttle tame, but thining about if using that is realy worth to give up kelly which has very nice features just because of a few ms, i have to investigate about those controllers than .
well i come from the motorcyle backgound and i notice allot the lag even if its close to zero i just notice it.
you dont want that, specially for trials

Re: LMX P2 : Freeride trials motorcycle frame development
I wonder if these controllers would work with th lmx motor? https://endless-sphere.com/forums/viewt ... 31&t=75888
I suspect not as i did read somewhere that the lmx motor would not work well with sinewave controller. Anyone know any different?

I need to purchase a controller and although the kelly kbs18 will do the job nicely the programming software looks really rubbish lol. It seems to have arbitrary units and strange function titles from the screen shots i've seen.

Yeah the kbs interface is nice
By the way they say kbs don’t work with Bluetooth adaptor but they do! Tried myself.
The Bluetooth interface that’s horrible but handy

Thanks guys, thats good to know, and cheers for the video link 
Yea, it was the KLS interface that i had seen,, very bad.
As you say the KBS is much better. I just looked it up on kelly website. Good

Is anyone running higher than 16s/58v nominal or is this the sweet spot for motor rpm and amps.

Re: LMX P2 : Freeride trials motorcycle frame development
yes myself I use 20s, but im curious to try the 16s, it might be a sweet spot as you said.
found this :
Pushed the bike more and had no problems with overheating.. The only noticeable issues were when I kept full throttle for a while like a
min, the continuous amps eventually dropped from 70s/80 to 60s and even 40s but that actually protects the motor and everything aha
Im also curious to try the new motors lmx as i have an old version and new ones tend to drop less or heat less
how do you cool these motors with liquid? hard job?

Re: LMX P2 : Freeride trials motorcycle frame development
We did it back in 2016, on the 50mm motors, but we found out the weight and complexity was not worth the improved/constant cooling rate. It sure did a big difference, but was turning our cheap motors into very expensive ones due to manual work and disassembly.spinningmagnets wrote: ↑Mar 24, 2018 3:46 pmAll it takes is time, tools, and money...how do you cool these motors with liquid? hard job?
We switched to 60mm and not looked back.

Re: LMX P2 : Freeride trials motorcycle frame development
Please only use KBS with our engines. it has been tested multiples times with sin wave like KLS or adapto, never with good results due to non ideal hall sensor signal. the Denzel engine is compatible with KLS because it uses external hall, probably with cleaner halls signals, but it adds bulk and weight.skeetab5780 wrote: ↑Mar 23, 2018 6:05 pm

How does the power of the lmx engine relate to a hub motor like the qs205, to get an idea of the power of the lmx engine?

generally, if you want more continuous power, your best ROI will come from putting more weight and volume into copper and iron, rather than water, radiator and pumps. 2kg of the latter buys you a lot of the former, with the added benefit of more peak power, and typically higher efficiency too! The only reason to go to active cooling is if you've filled whatever space you can where your motor resides with copper and iron first. There are some exceptions (such as a hub motor, where the extra weight may be better placed on the frame by way of pumps and radiators than more unsprung weight) but generally, invest in Cu and Fe before H20 and Al.

Re: LMX P2 : Freeride trials motorcycle frame development
KBS = trapezoidal controllers
KLS = sinewave controllers (which seems to be way more sensitive in terms of hall signals or probably motor design generally)
The kits from Denzel also have trapezoidal controllers (even the large D7500 one which would have the halls outside and away from the windings).

Re: LMX P2 : Freeride trials motorcycle frame development
What about a matching bms for the lmx motor. I am currently hunting one down. I suppose 50a continuous and 120a peak at a minimum? Or is that conservative?
I am finding it particularly difficult sourcing a bms that will be reliable and has the correct amp rating and has a seperate (C-) port for a charger plug.
If anyone has any ideas please post it up. I have asked Bestech in China if i can purchase this... http://bestechpower.com/592v16spcmbmspc ... 223V1.html
But have heard nothing back yet, and they probably over charge for single item or have minimum order.
I see that on the LMX website there is a 50a bms for sale, but there is no information or images , so i am not sure if it will be compatible with the current lmx motor. Adam? Any details on the bms you sell?
