If anyone has purchased a 5102 recently and actually RECEIVED a 5102 I’d love to hear from you or a link from the seller. Thanks! 1 Quote Link to comment Share on other sites More sharing options...

Possibly an employee sniffed the transmission from an update chip and figured out how to load custom firmware onto the chip? Or are they using a custom control board? Or possibly a collaboration with Gotway? 🤔 Quote Link to comment Share on other sites More sharing options...

EUC Service' relationship with Gotway goes deeper than just being a dealer. Quote Link to comment Share on other sites More sharing options...

I can do an update for you guys once the wheel arrives with pics and all that if you are interested. 2 Quote Link to comment Share on other sites More sharing options...
GoGeorgeGo Posted July 10, 2021 Share Posted July 10, 2021 (edited) By any chance does anyone have a measurement for the hole in the shell on the original versions of the EXN? I got some of this amphibious filter material that really seems to trap water great. Im thinking about 3d printing a tpu brace to hold it in place and covering the hole with the material. I would open my machine but its currently all gooped up with silicone and i need it to stay sealed for a long ride sunday. Ill crank her open monday unless someone happens to have an answer for me 🤘. I will share my progress as i go Edit : https://www.amazon.com/dp/B00230CRYW/ref=cm_sw_r_cp_awdb_imm_FQXRHG6FJ1WVY905YPSK?_encoding=UTF8&psc=1 this is the material i will be using. Might try putting some over the tail light air vent as well and maybe even over the power button. Stuff is cool, it literally holds water like a cup but air passes through it freely Edited July 10, 2021 by GoGeorgeGo Quote Link to comment Share on other sites More sharing options...

EMA Posted August 5, 2021 Author Share Posted August 5, 2021 (edited) finalized and tested a ventilation hole on the EXN/EX, works really well and drop the temperature by a lot. Used two quiter fan instead stock one and also inverted the air flow inside, now from bottom to top STL: https://www.dropbox.com/s/n4k0ilaixhrpp38/EXNairflow.stl?dl=0 Edited August 5, 2021 by EMA 2 Quote Link to comment Share on other sites More sharing options...

Popular Post btl Posted August 5, 2021 Popular Post Share Posted August 5, 2021 Here is my approach. I closed the internal hole and made new ones. in the front, with filter behind them for intake, and then down behind the circular arranged holes is my 80mm outtake fan. Much quieter and also less hot than original. 4 Quote Link to comment Share on other sites More sharing options...

I weigh about 110 kg with my gear, average speed of 32.4kmh. Beeped just before I got home and after letting it sit for a few minutes the voltage creeped up to 80,1. So much power on tap, though I got it to skip magnets while breaking HARD, -38,8 A during that. Acceleration doesn't suffer from magnet skipping, pulled 133A and pedals didn't even dip. "got to get used to gotways power deliver and how it tilts pedals up when you accelerate at speed" This behaviour is only on the mss line, it overwrites hard mode and replaces it with what Daniel calls Sport Mode. 1 Quote Link to comment Share on other sites More sharing options...

Maybe little better torque, but pedal dipping limit is the same i think My personal (105kg rider) feelings. 2 Quote Link to comment Share on other sites More sharing options...
