Hi Johan, there is no real diagram to share about, I gathered every thing from Daniel explanation over here and on pedelecforum.de forum (home for FC)... In my case it is almost the same as Daniel describe except that I am not using Teensy, instead I did a small PCB and attached to it the controller soldered to an adapter PCB. I am using same controller as in Teensy so fully used Daniel code, the difference is in programming the controller which I did by using Jlink... Then FC takes all the signals like brake, control switches, speed and PAS sensors and communicate with VESC over serial as well it takes the power supply from there... If you are around Stockholm then you are free to come over and see my setup...

Thanks, clear, assume CS is used for selecting between display or SD card reader, which is not required... One more question, looks like you are not using analog throttle, instead one button for power boost when required? Otherwise PAS sensor is the main input for the bike to ride?

Hi Daenny, looking down to your display code, is it on porpose or pinout mistake? #define TFT_CS 10 #define TFT_RST 10

Thanks for your reply Daenny, clear enough, will try to move forward by using your setup...

Hi Daenny, Nice I found your post, I was planning similar setup, have already GSM middrive, next looking forward for VESC... in my understanding you use curently available version 4, have you done any changes/adaptations on controller side? And why 32 bit Teensy instead of Atmega?

Yep, this is what I consider too, possible is a better trade off to have bigger mass on motor side than in gearbox... I think I am convinced about better investment in SWX02 than Xiongda... Thank you all for your feedback and advises, it helps me out on my final decision.

I was almost certain on Xiongda before finding SWX02 to have same mass and aproximatively same torque if comparing Xiongda in low gear... Two speed hub motor is attractive idea, in theory it should provide a better milleage, and main question was if it is worth of it... I was ready for a try thus wanted to know peoples opinion who knwo both motors. By now I am sliding toward SWH02...

My main dillema is to decide between these two hubs considering the outlined points, potentially higher efficiency for Xiongda versus better reliability for SWX02... I want to retrofit my existing e-bike, thus I am looking for front motor as an easy option. The bike is having steel frame and fork and is quite heavy... The front dropout width is 100mm and it does have rim brakes, to me it looks perfectly ok to accept ether Xongda or SWX02. I will post a picture in the evening....

Thanks derf, that sounds promising...

Thanks d8veh, that answers my question, it looks like Xiongda would really shine in very hilly area you would need very frequent change for the gears, that added complexity would be offset by drive efficiency and torque availability on demand... I am tending to give a try for this motor, I have factory built e-bike with front drive which do not satisfy my needs and would be a very easy adaptation to Xiongda... my fear is only about the possibility to have the motor locked out mecanically while in high speed, that's why SWX02 is on the table too ... do you think this is a real issue or my conclusions are wrong? If taking care about rolling back the bike accuratelly and not to screw up the gears if it is locked, do you think it will be good enough to prevent sun gear shelling?

Hi d8veh, New to the forum, however reading it for a while... little bit old tread however actual for me (almost replicated my question on endless-sphere), possible you know now more about, how is comparing SWX02 to Xiongda in terms of hill climbing ability? How close to the reality is declared torque of 45N.m, I assume it is correct model: http://www.woaczh.com/show_content.php?id=3917
