John Eucist Posted October 1, 2016 Share Posted October 1, 2016 Thanks for sharing this. I noticed in your video description that you used the "6 mosfets" version. Do you think it would make any difference if it were the "12 mosfets" version or is it irrelevant in terms of top speed loss of power? Link to comment Share on other sites More sharing options...
sbouju Posted October 1, 2016 Share Posted October 1, 2016 The road was lightly descending, no ? Link to comment Share on other sites More sharing options...

John Eucist Posted October 1, 2016 Share Posted October 1, 2016 I think, possibly, the tilt back threshold actually caused the shut down since, I think, it requires a brief surge of power to make it tilt back and it was already near the hardware limits at the time.

Cloud Posted October 1, 2016 Share Posted October 1, 2016 @EU GUY thank you forthe test, for the fantastic video and for taking the fall for the community. how much do you weigh? Link to comment Share on other sites More sharing options...
JoyRide Posted October 1, 2016 Share Posted October 1, 2016 Well, you scared me a lot! I got me ACM 16 to ride faster but I will reconsider. Currently, I am riding at 25-30 km/h and my top speed was some 32 km/h. However, one week ago, I let my ACM to one guy (much more experienced than myself) who wanted to test the speed (he has Ninebot if I recall correctly) and he made easily 42 km/h. Not more just because the road was too short. (btw, tiltback was off) Thank you very much for posting this. I believe everyone shall watch it, especially when one thinks, he has mastered the wheel. Wish you fast recovery! Link to comment Share on other sites More sharing options...
John Eucist Posted October 1, 2016 Share Posted October 1, 2016 @EU GUY What has been your experience in terms of the Gotway app speedometer vs GPS speedometer for your ACM? We all know during the MCM2 days the Gotway app had inflated speeds. Also, which Gotway app version are you running? Link to comment Share on other sites More sharing options...

Tishawn Fahie Posted October 1, 2016 Share Posted October 1, 2016 just got my ACM maybe 2 days ago.... I think I'm going to try a similar speed test. The difference being the 12 Mostfet version. Just gotta find a nice flat straight away.. And purchase some IRON Man armor! Because I'm still confused - He had tilt back set on 45km but he had the option to set it to 48km..... which leaves me to believe theres wiggle room for more power.. I believe it's the 6 mosfet board is why is why it cut out on you.... Again thank you for your bravery! Link to comment Share on other sites More sharing options...

I guess i shouldnt go over 35 then!!! It's possible that max speed power cutouts (unlike lack of torque) are not weight dependent. Although I'm not certain. Perhaps others can chime in on this.

I believe 45 is not the no load top speed for ACM. But if i was wrong, it would be very nice Link to comment Share on other sites More sharing options...
JoyRide Posted October 1, 2016 Share Posted October 1, 2016 Not sure if this is relevant to no-load max speed but when I lift my ACM when on, the WheelLog shows ca 46 km/h. Link to comment Share on other sites More sharing options...

JoyRide Posted October 1, 2016 Share Posted October 1, 2016 Was curious and went to try again now. The WheelLog showed 52.6 km/h before turn off. Link to comment Share on other sites More sharing options...

Same here and this is why it doesn't make sense. Don't get me wrong 27 mph is way to fast... But advertise speed is advertise speed..... I'm no electrician but i'm pretty certain your board version couldn't handle the load... Link to comment Share on other sites More sharing options...
Xima Lhotz Posted October 1, 2016 Share Posted October 1, 2016 Hmm, well I'm glad you didn't hurt yourself to much doing that speedtest. Why not try it with a shopping cart (or similar) so when the wheel fails you just continue riding that? Or use rollerblades and hold the wheel with your hands? Or use a skateboard? Or anything else with wheels so that you don't fall? The friction will be similar or more so you know it will be safe if you only ride the wheel later on. Well just a thought..

JoyRide Posted October 1, 2016 Share Posted October 1, 2016 Shopping cart seemed to me a good idea when trying to learn to go backwards. I tried that but still need more time to practice. However, I cannot imagine myself riding with shopping cart at supermarket parking lot at 45 km/h. I guess, there is even some speed limit in these places. Re Anything else, well, the point is that the wheel must be loaded, right? So, you must stand on it. So, rollerblades and your wheel in the middle is rather not an option, right?

I had a brain fart and thought it would be a good idea to test the speed right there and then. Just something i had to get out of my system i guess.

I dont think using any of this is possible to both adequately test the max torque/ speed under load and still not take the fall. Link to comment Share on other sites More sharing options...
