Pas stopped working after just two rides.

[Curcutie]

My x3 pro just came in and the pas stopped working on my second ride. Throttling still works so I went to check the connector by the pedals and they’re connected. I just emailed Wallke. Sighh it’s such bummer cus I only got to ride it two times and I mostly just pedal.

Update: Wallke told me to restore factory setting and it fixed it.

ok it went out on me again. Basically you can’t tweak the settings too much.

Would you share the email of who you contacted at Wallke? I have a problem with the speedometer dropping to zero when I coast. The tech I contacted said thats normal. Seems not so since it wasnt normal until it started happening. Any help is appreciated.

 

[Curcutie]

Mines like that too. I know it’s kinda annoying but I don’t think you can do anything about it. Their email is on their website.

Thanks. Ive got response from others that say its not normal. I folded my bike which effectively disconnects the battery, and when i "reboot the display, it now at least stays on down to about 8 miles oer hour befire suddenly dropping yo zero. Also realized i have no regen happening. Others have said if they are coasting above 12 to 14 mph, in PAS 0 or 1 the watt meter turns red indicating recharhe back to the battery. Mine just stays green and reads zero. So, seems something isnt right. Probably controller or display or broken wire or something. Will see what Wallke comes back with. Thanks for the reply.

That's not "normal" at all. I don't care what they're telling you. Don't accept that as a final answer. That issue is typical on many gear driven rear hubs as well as mid drives. They'll need a simple external speed sensor installed. One that doesn't stop getting a signal when coasting.

Have you asked other wallke owners if their bikes are like that? I’d like to know too because my lectric XP shows the speed thru and thru.

Ok I made another thread on this issue that we both have. Let’s see what ppl say.

My bike is x3Pro May 2021 delivery. After my complaint, the Wallke rep responded, basically said my bike is "non compatible" for regeneration to work, and that unless I am applying power to the motor, my speedometer, and odometer will not function, and that it is designed that way...lol. Only works if pedaling in an assist mode, or throttle.... coasting or PAS 0, no speedo, no trip odometer.... regretting tbis purchase, and it hasnt been a week.
My concern is that the rep is not being honest or is simply mistaken. After 2 times back and forth, hes saying the same things, sticking to his story. A wiring diagram would be nice to troubleshoot with. I suspect the regen feed wire back to the controller may be disconnected, and power supposed to be supplied from the hub isnt going to energize the display, and not creating regen current. Seems the regen and speedo issues could be related. But thats just a guess, and I wont open anything unless instructed by a competent technician. If I could get someone to guide troubleshooting it might get fixed. If its the motor wiring though, and the rep can save sending me a motor by just saying, "its supposed to be that way" then they save $ dont they? This is not the service I was expecting from reviews of Wallke that I read previous to ordering. I also watched a number of youtube reviews that raved about the wpas regen capability in the 2021 models, and now to simply be told it really doesnt have that function is beyond disturbing. I'ts beginning to smell like a scam to me. Oh, you have no regen?, well, your model not supposed to have that... oh, no speedometer when coasting? Well your model not supposed to have that.... Not sure where to go from here.

Dang I feel cheated now. Yea no regen here as well. My dumb ass thought the battery fluctuation was the regen.

Guys, there's only one gear driven rear hub that offers regen. It's pretty sophisticated ($$$) design and it's called a GMAC, available only on the aftermarket for the most part. The only way you can get regen otherwise is with a direct drive hub, and in my opinion, they're gutless compared to what you have. Good news/bad news kinda thing. Even if you did have regen, it's only value is to help hold your speed in check going down BIG hills. As far as putting anything useful back into your battery, that's a joke.....

The Wallke rep is mistaken on the speedo, or he's to cheap to tell you that it needs a 10-15 dollar external speed sensor and a slight wiring mod to give you a full time speedo. I don't know enough about your bikes to be useful regarding the required wiring mod, or I'd be happy to guide you through the process. -Al

Al,
Thank you so much for your reply and help. You gave more insight in a sentence than the Wallke rep has in a week of emails. Actually, it seems the rep is simply a curteous translator with little technical knowlege, as he often has to "check with colleagues" and has been the only contact from ordering through shipping and now customer service. At one point I thought Wallke may be a 2 person company importing bikes. Thanks for talking sense into me by sharing your experience. I trust what youve said, it makes perfect sense. I'm pretty mechanically minded and tech savvy when I get an interest in something, but this is my first foray into ebikes. Im thinking they likely switched direct drive to geared motors, as you mentioned, and simply left the controller and display from the direct drive. Id like to think after enough people complain, they may distribute something for the speedometer fix.
Since nearly every ride I'll do ends in a 1500' elevation change to get back home, think I'll unvest in another battery that can be switched on for my last legs home so I dont need to muscle a 70 lb bike up the hill!
I'll wait until the rest of the Wallke warranty expires then would love to contact you for tips on modifying the bike, fixing the speedometer, or maybe building one from scratch, if thats ok with you? Im greatful for your input. Thank you.
John

If you understand tech and have a tech background, an external speed sensor is likely very "doable" for you.

The speed sensor has 3 wires. A ground, a positive (something in the area of 4.5v) and the sensor lead. The wires to the motor, will be 3 big phase wires, 3 sensor wires (probably the same colors as the larger phase wires), a positive (with something in the area of 4.5v on it) a ground, and very likely a part time speed sensor wire (that might be white?).

An external speed sensor is going to look like this, but you might want to track one down that shows it's internal wiring diagram to save you the trouble of figuring out which is which. They're universal, wheel size makes no difference.

Sooooo, all 3 of the wire that you would need are going to be available in the motor harness and likely easy to access at the controller. You would want to "T" into the positive (4.5v) and negative wires, and locate the speed sensor wire. When the speed sensor wire is located, you would cut that, and splice the newly installed external speed sensor signal wire into the side of the cut leading to the controller.

Best of luck! -Al

I'll check that out. You have been a big help.

My pas stopped working yesterday, throttle still working. Factory reset did not help. What was your final solution if I may ask?
