My new electric motorcycle

Usually when talking motor spec it is about continuous power.
So if you have a 2,5kW continuous motor, you could easily get 10kW peak power.
If you do, you could call it a 10kW bike and not really be wrong..

That is probably what is happening, you have a controller suitable for a 2,5kW continuous motor.
The controller is capable of 10kW peak, and if the motor is too you can call it a 10kW bike.
It will only do it for seconds though :wink:

And a 10k watt motor setup would blow past 70mph... With correct batter, controller, and motor he should be at about 110mph no problem.

He got back to me after I sent him the pic

 

[colworth]

What does that even mean? Have you left a review on Alibaba yet? Make sure to include this picture. I will be leaving a review, (good or bad) with pictures of the actual motor specs.

 

[Albie72]

I looked on Google that's what the call it debug

 

[Albie72]

I was told that fardriver and other controller companies test there controllers on one motor so they probably tested mine on a 3000w motor

 

[colworth]

Any updates on your motor? I do believe they test on a 3000w motor, but it should be reading your motor correctly. I think if it was a 10000w motor, they would have sent a bigger controller to begin with. 150/300a is not eneough for that motor.

 

[Albie72]

All he said it has to be debugged .took the bike to work today ran the best it ever did who knows

 

[Albie72]

Does anyone know why I have a red exclamation mark with a circle one this screen I connect to my controller

 

[fechter]

Looks like a brake switch indicator.

 

[Albie72]

Is it just saying I'm in park when I go on the app

 

[Albie72]

Here she sits now getting the rest of the fairings painted. Good news the clunk I thought was coming from the forks it must be the plastic cause I rode it like this and no clunk

 

[colworth]

What does the MCO that Andy Han sent look like? Did it say "Motorcycle" and "Street Legal" or Scooter Not for street use? Thanks!

Similar to what j bjork said a few posts above re the motor size, these Chinese Electric Motorcycles have been sold in my area for years with the base level being a 500w motor (nominal power) and 2000watt "peak " power. With that setup they can be used as ebikes in my area or you can register as a LSM (low speed motorcycle) where you can insure, plate, and ride with a regular motorcycle license. They go about 45mph/70kph with this setup. You can option them out with more powerful motors/batteries but then you need a motorcycle license as they're seen as a regular motorcycle.

Taking this into consideration, yours billed at 10000 can be correct - its likely a 2500watts nominal motor with 10000watts peak power.

 

[Albie72]

Yea I talked to some one on another forum I need a better controller and bigger battery. Good news I took the fairings off for paint and there's no clunking while braking hard so it must be the fairings

 

[Albie72]

Got my bike running and put back together.long time but finally done

 

[Advn2ur4me]

Can you provide an update on your bike and experience with getting it registered? I'm in California and looking at the Ouke model DMG-N with the 72V150a battery

Hi, I have the same motorcycle (WUXI JOSE VP5M), and I'm curious whether anyone else has experienced similar issues.

So far I've found three major problems:

• the VOLTSHIELD H400 (VS001) dashboard doesn't display any BMS data,
• the speedometer is significantly miscalibrated,
• the onboard charger stopped working shortly after delivery.

Has anyone else encountered any of these issues or found a solution? I'm especially interested in the dashboard calibration. I suspect the onboard charger will need to be replaced completely.

• the speedometer is significantly miscalibrated,

I bought already several chinese 2 and 3 wheelers and every each of them have miscalidrated speedometer. Usually showing between 10 and 20% higher speed like the reality. Checked with following wehicle, gps application and even with police speedcheck. Probably easier to set up a "msicalibrated" speedometer, than making a faster vehicle.

In this case, the situation is actually the opposite. The speedometer reads below the actual speed, not above it. At a real speed of around 120–125 km/h, it displays only about 100 km/h (verified by GPS).

The problem is not that the motorcycle appears slower But that it becomes very difficult to stay within speed limits. More importantly, a speedometer that under-reads does not comply with UN Regulation No. 39, which requires that a vehicle's speedometer must never indicate a speed lower than the actual speed. As a result, using such a vehicle on public roads is, in practice, not legally compliant.

I suggest for you to buy any simple backup (aftermarket) speedometer what is comply with the regulations, and isntall it. Or find a professional who will install for you officially.

Thanks for the suggestion. I already use an external GPS speedometer, so I know the actual speed. Unfortunately, it can only be mounted on the handlebars because there is no space next to the original display due to the shape of the dashboard plastics.

However, that wasn't really what I was asking about. I posted my question in this thread because I saw that several people here own the same motorcycle, so I hoped that someone might have encountered the same issue or know how to calibrate the speedometer.

If you look at instrument clusters made by SIAECOSYS, for example, they have a fairly comprehensive service menu where you can configure battery parameters (to display the correct SOC) as well as motor and wheel parameters (to display the correct speed). I'm therefore looking for information about the service menu of the VOLTSHIELD instrument cluster. Unfortunately, neither the supplier nor the manufacturer is willing to provide any documentation.

If I can't get the VOLTSHIELD display working properly, I'll most likely replace it with a different instrument cluster, possibly one from SIAECOSYS.

First I would try to change the wheel parameters in the controller.
Most of the displays get their informations from the controller via lin-bus.

Thanks for the suggestion. I actually hadn't considered that the speed calculation might be done by the controller rather than the instrument cluster.


My bike is equipped with a Nanjing FarDriver IPMSM controller (JS72V270A_27_1_H98). Since I noticed in your profile that you're also using a FarDriver controller, could you perhaps point me in the right direction on how to connect to it and access its settings?


I've attached a photo of the controller label in case it helps identify the hardware revision. Thanks!

 

[dominik h]

It's an ND72680 controller.
At first I would look if you can reach it via Bluetooth. There are versions with built in Bluetooth and the others have a separate Bluetooth Adapter.
It should Show up as "Yuanq...".
If not you have to look if your Controller has the plug for the Bluetooth or if this is also missing.
