Purchased Wuxi Stanford DP Racing direct from factory on Alibaba. 5000W (8000W peak) Have done 48 miles on a charge (72 volt lithium ion). Top speed 65mph. Great bike, and only $2380 delivered to my driveway including all customs and freight. My only issue is with the instrument cluster. It shows speed in km, a fluctuating voltage that seems to respond to throttle input, Kms traveled, and total kms. The #s 1-4 and a swoosh colored from green to red do not light up. Therefore, I do not have an obvious way to determine the range remaining on the battery. Does anyone have a similar issue, and how do you deal with it ?

Welcome, cobeighb. I have never heard of the brand and I hate to say it, but I have never heard of Alibaba, either.  Sounds like a fair price, though. Where are you located?  Can you post a photo of the bike?  My guess is that the bike's voltage display should tell you something about the power left in the battery pack. You may have to rely on trial and error to determine the bike's range.

Thanks for the response. I am in Vermont, which “ain’t flat”, so I was pleased to go 48 miles. Alibaba is China’s Amazon. As for the voltage reading, when the throttle is closed, the reading is a steady #, which decreases as kms are covered. I guess I will have to rely on that reading as it approaches 72 volts, which is time to head for the shed. Don’t want to find out range the hard way, pushing 250# down the road.

Alibaba is the Amazon of the eastern world.  AKA we got everything.

Cobleighb, the voltage will "sag" and rebound when to go and stop.  The Zero's most of us have on here will go from 116V fully charged to about 95V when it's at 0% state of charge or SOC.  For a Zero full battery street bike that's around 110 miles depending on how you ride it.

Find those two voltage points (high and low since yours is 72V) on your bike and you can guess your range from that.
Note: don't drain it down too often try to leave a 10-20% bottom end for longer life.

Thanks for the voltage info. When fully charged it reads 84-85 volts, but when I Unplug it, it drops to 81. Someone from the factory said to not let it drop below 74. So,If I never let the low/throttle off voltage drop below 74, I should be good. After 48 miles it was at 76.
Buying a bike directly from the factory in China seemed sketchy, but, for $1680 plus another $980 for all fees and freight, I thought it was worth the gamble. So far, so good.

Pictures! Or it didn’t happen[emoji6][emoji2]

Here’s the picture, I hope!

That is one of the best looking electric motorcycles I have seen.  All it needs is a larger battery and a more powerful power train and Wuxi would have an EV market winner.   

[NEW2elec]

Yeah I think of bikes like this when people say how very expensive it would be to make fairings for other bikes (cough Zero).
That bike seems perfect for China or India and some of their traffic issues. 

I wonder how long it will last and how it could be repaired but at that price you could forgive a few issues.
Enjoy and keep us posted on how it works out.

Dash with DIY analog kph/mph converter. 790km so far with no issues.

I just enlarged the other picture.  It says "Lighter", for a second there I thought it said Lightning.

There's a joke there if you've been keeping up with other threads. 


Anyway back to the OP.
What is your charge time?  I'm guessing only level one charging but maybe they have made super cheap level 2 charging too.

[cobleighb]

Not sure on the charge time. I plug it into the wall after riding and it charges over night. Factory says 8 or less. As for the lighter, based on my communications with the factory in China, which were an exercise in code interpretation, I’m guessing maybe it could be “liter”. That having been said, their English is a hell of a lot better than my Chinese. Who knows. I have not been following the other threads, so can’t comment on the jokes.

I thought that too but then remembered Lightning aren't actually selling a bike.

That said, I'd be paranoid to ride a Chinese EV motorcycle from an unknown brand, although I'm sure the parts are made out of the finest Chinesium.

Nice looking bike. Hope you will enjoy and get no issues. Keep posting ;-)

Better then +400# UP the road.   DAMHIK

Nice looking ride, hope it holds up in the long run.
