John Eucist Posted April 12, 2015 Posted April 12, 2015 Glad you didn't get hurt and alive to tell us.
EUC Extreme Posted April 12, 2015 Posted April 12, 2015 Ugh No, it was nothing. Since then, I have often pushed completely turning off position. Just a nanosecond before the engine stops, pedals decreases rapidly down. If you are a super-fast, it is possible to save the crashing. I've done it many times. Gotway 18 "is deceptive because it accelerates incredibly quickly and quietly in the maximum speed. And the maximum speed feel anything, because there are so stable. Therefore, a top speed could be increased
John Eucist Posted April 12, 2015 Posted April 12, 2015 Just a nanosecond before the engine stops, pedals decreases rapidly down. If you are a super-fast, it is possible to save the crashing. I've done it many times. Austin Marhold described exactly what you were talking about on his GW14 MCM at 26 km/h (true gps speed not gw app speed). The ability to feel when it's at the limit right before motor cut off. I have never dared to test the limits to experience this phenomenon. BTW was your 40 km/h fall true gps speed or gw app speed? I guess gotway app speed since you were in a parking lot. The gotway app inflates the speed by several km/h.
EUC Extreme Posted April 12, 2015 Posted April 12, 2015 I am talking about Gotway showing the app speed of reading. Because it is all easy to say and to compare their own. The app is reading in the sense of a more reliable because it is truly real-time. There is no delay as when the GPS. And can quickly run close to shutting down. GPS-measured maximum speed of 37kmh
hobby16 Posted April 12, 2015 Posted April 12, 2015 If you do decide to test the limit you are using this 20% and leaving no reserve for balancing when you do hit a dip or bump and obviously if you carry on pushing the limit you will find it and the wheel will give up. The speed at which this happens is not a constant and will vary with all the above mentioned variables. What do you mean by "give up" ? If it means, the wheel is at its max power, doing its best to keep your balance but can't, I would agree. If it means : the wheel shutdowns the power... to keep you from possibly falling, it's rather crazy if true. As to saying the cut off has "nothing to do with battery charge", I totally disagree. Just look at the BMS of a Gotway : it has mosfets which shutdowns the power (without warning) if the voltage drops too low, resulting in a cut off.
Gimlet Posted April 12, 2015 Posted April 12, 2015 From what I've read Gotway have calibrated their speed reporting within the app by running alongside a car and comparing the speedometer. Unfortunately most cars are set to register 10% over the actual speed so that would explain why the app reads about 3kph fast at 30kph. It doesn't really make much difference if you know about it, you just do the calculations and allow for it. It's a bit like a UK & USA users who are used to mph rather than kph having to make the conversion, only much simpler.
Gimlet Posted April 12, 2015 Posted April 12, 2015 Let's face it everything is governed by the laws of physics. If you have a finite amount of power you either put safeguards in to prevent that power being exceeded (pedal lifting) which attracts criticism for not using the the available power as these obviously have to be set low to allow for the worse case senario or you allow the use of that power and put in warnings that make the rediculous assumption that you just might take notice of them. Not all of us require a big notice on the bottom of an aluminium ladder telling us we might get electrocuted if we rest it again an electric cable!

Usually you can just calculate it by the diameter of the wheel (incl. tire of corse) and the impulses you get from the wheel and then you know it exactly! This is like a pro would do it if you have a cab (taxi). In a cab (here in Switzerland) your odometer has to be tested every year and adjusted if nessesary (the tire size will be in the certificate listet). And if you not do it so. You have a testtrack where you know the distance, then you can adjust your item for the same result.
hobby16 Posted April 12, 2015 Posted April 12, 2015 What do you mean by "the wheel will give up", Gimlet ? Can you substantiate it, please ?

Yeah, the story of "calibrating by running alongside a car", rotflmao. Even a $5 bike computer is surpringly accurate, better than 0,1% on distances (hence speed). I have it on my wheels, on a known ride of about 400m (measured by Google map), it's so accurate I am able to detect a change in tyre pressure!

I have it on my wheels, on a known ride of about 400m (measured by Google map), it's so accurate I am able to detect a change in tyre pressure! I forgot this. You are right, this is also just calcualted by diameter and a signal sensor per turn. So GotWay does it maybe more for they can give there wheels a higher max. speed then it really is! It is arround 15% higher then it relly is! Also for Gimlet (sorry do not understand it wrong) I think the high torque version of the GW18 is to slow (there are only 25km/h left) and dangerous to out lean it (and fail) for this race wheel. As vee73 also wrote, it is really a hot and fast machine and from 0 to 25 so smooth that you do not realize it! If I drive to GW18 or the GW14....with the GW18 I am all the time to the 2 beeps, even on gravel (not so with my GW14)

Unfortunately most cars are set to register 10% over the actual speed so that would explain why the app reads about 3kph fast at 30kph. As Tom pointed out. The speed can be calculated by wheel size alone. Also, why would most cars be calibrated to show 10% over the actual speed?
^tom^ Posted April 13, 2015 Author Posted April 13, 2015 As Tom pointed out. The speed can be calculated by wheel size alone. Also, why would most cars be calibrated to show 10% over the actual speed? By law here, the speedometer MUST show a higher value then you really drive. I do not think this is the point at a GotWay...haha

I guess gotway app speed since you were in a parking lot. The gotway app inflates the speed by several km/h. I have also ran into this. had the volume too low to hear the beeps, and didn't have the gotway app open for vibration, got going too fast and suddenly the wheel went "soft" not a loss of total power, and I was able to recover without falling, It needs quick reflexes, but the battery doesn't just cut out, you lose some power first. I blame my dog, who I was walking at the time he wanted to run.
Gimlet Posted April 14, 2015 Posted April 14, 2015 Just out of interest I did the lift test on the M10. Here's the results: Double beep 19/20kph Triple beep 21/22kph Constant beep 24/25kph Runs constantly at a maximum of 32kph and cuts out at 33kph

^tom^ Posted April 29, 2015 Author Posted April 29, 2015 Two days ago I tested the same ramp with my Rockwheel GR12 (geared). Result: NO problem to start "in" the ramp even with only half full battery. I could not test to start at the bottom (corner from 0 to 17°), because they wreck it down now.
Gimlet Posted April 29, 2015 Posted April 29, 2015 But its a well known fact that gearless cannot compete with geared wheels when it comes to torque. However they do tend to last a lot longer.
^tom^ Posted April 29, 2015 Author Posted April 29, 2015 You are right. But usually then there are not that fast as the non geared ones. In this case, the Rockwheel also pretty fast (I do not know how fast, but arround the same as the GW14). I did it only, to see, the Rockwheel really can do it without any problem.
^tom^ Posted May 3, 2015 Author Posted May 3, 2015 Not me, the high torque is not fast enough for me (for security reason I like some km/h left). The HS runs only 28km/h and this is by GPS only arround 25km/h (sorry it is not the HS that runs only 28, it is the "High Torque" with only 28
GQS Posted May 6, 2015 Posted May 6, 2015 Just out of interest I did the lift test on the M10. Here's the results: Double beep 19/20kph Triple beep 21/22kph Constant beep 24/25kph Runs constantly at a maximum of 32kph and cuts out at 33kph Is this for the mten2 (gearless)?
Gaston Posted June 13, 2015 Posted June 13, 2015 I had the chance to drive the high torque version at a slope. It was amazing how much power this MSuper has compared to IPS, Ninebot and Firewheel.
StreetMeatNYC Posted April 10, 2016 Posted April 10, 2016 On 4/12/2015 at 10:40 AM, EUC Extreme said: okay I also tested the lifting And it does just as your version of Speed. It therefore behaves differently when driving as if lifted up. Interesting. When driving, the engine shuts down at 40 kph, and raising 48kmh. That said, I therefore have the correct version Could this somehow be changed so that, it will fail the driving 48kmh? I would consider this My guess would be based off the weight it will have a much large load and therefore cut out earlier. The lift test tells you the true limits of the machine, no load...
