Cyclotricity definitely don't want to give any info for some reason: Me: I have the 250w/1000w rear wheel conversion kit. I would like to change the KT-LCD1 display for a KT-LCD3, for the extra functionality. P6 is not available. Are there any other C params that I would need to change? Cyclotricity: yeah you will need to change all of the setting but you will be told this in the instructions. Me: Thanks for the reply, but which instructions? I have the manual for the KT-LCD3. It doesn't have P6 like the KT-LCD1. I need the tech specs for my motor to be able to set up the P and C parameters on the LCD3. My motor is a JDLAX1707RD0016 marked 28" -48V"250W Restricted" Supplied by yourselves, through Powerbikes in Whitehaven. Cyclotricity: Normaly the LCD3 comes with instructions to tell you how to change the settings on the bike. did you not get any paper work? Me: Am I right in thinking that the KT controller supplied in your kit is programmed to require connection to only the KT-LCD1 before it will supply the current to achieve the full 1000W? Therefore connecting it to a different display will not work (will only supply 250W). Cyclotricity: yes that's correct you will need the 1000w controller to get the 1000w power from your wheel, but you can limit it to 250w if you set it to that on the on bar display, Give Up

Yes. I was coming to that conclusion. Once I found out that the controller was programmable, I realised that this must be where the function must be that ties the system to the LCD1. I’ve been looking at this article as a possible solution, but aren’t willing to hack my only controller. Yet. https://opensourceebikefirmware.bitbucket.io/windows_instructions/

Yes. C5 is set to max 10. P1 - 46 P2 - 0 P3 - 1 P4 - 0 P5 - 15 P6 - 99 (only on LCD1) C1 - 2 C2 - 0 C3 - 8 C4 - 0 C5 - 10 C6 - 3 C7 - 0 C8 - 0 C9 - 0 C10 - n C11 - 0 C12 - 4 C13 - 0 C14 - 2

I've uploaded the KT-LCD1, KT-LCD3, motor and controller

As stated in my post, my motor is a 250W/1000W. The kit came with a LCD1, and this unlocked the 1000W by the use of parameter P6. I have copied all parameter settings on to my LCD3, but it doesn't have P6, therefore it all works great at 250W, but it doesn't unlock the 1000W power. I have emailed Cyclotricity and they have replied, but are being a bit evasive about the info. If they would provide the motor characteristics (spec) such as Motor Gear Reduction Ratio × Number of Rotor Magnets etc. I might be able to figure this out myself. I suspect that they may have a different firmware for the LCD1 that they send out with the kit, as the first one they sent me didn't detect my motor size and didn't give me P6. The replacement they sent me worked out of the box.

I fitted a conversion kit from Cyclotricity. A 250w/1000w motor and controller. This came with a KT-LCD1, which the first one had to be replaced by them as param P6 did not appear to allow derestriction. The replacement came and immediately worked. I can only think that it must have had a different firmware, as everything else worked identically. Cyclotricity's support was excellent, and they sent the replacement out next day delivery. I have just sent them a query with regard to upgrading to a KT-LCD3 that I have,and what to set the parameters to. As there is no P6 parameter to de-restrict. Can anyone else help? My motor is marked with JDLAX1707RD0016 28" -48V"250W Restricted". Does anyone have the tech spec on this motor?

I had a problem with the magnet reluctor ring slipping on the crank, or moving sideways away from the sensor. I squared it up and used hot melt glue. Works a treat
