EV Bikes Taillight Always On

[carlyai]

Have 2 E bikes that have not been used (I bought the wrong ones). 

After a few months away I come back to both tailights on, even when the battery switch is off. So me thinks it means to recharge the batteries (no manual). Charging the batteries did nothing to extinguish the lights.

Just enquiring with EV bike owners if this has happened to them and what the fix is?

Is the battery removable for charging?  Some of my recent e-scooters are lights on whenever the battery is in and connected. 

 

But I'm just guessing, having owned about a dozen different e-bikes and e-scooters in China and Thailand.   

 

Possibly a safety thing to remind me to take the battery out to reduce risk of fire.  They also have a "find my bike" feature that uses GPS and requires power all the time to enable that feature.  On those, I just disconnect the battery, even if I'm not going to remove it.  It's as easy as unplugging an iron in the house.  And I figure it makes the scooter safer from battery fires.

 

The older ones (20 years ago) had lead acid batteries that required some disassembly to remove them, and those batteries were too heavy to bring inside.  On those, turning off at the switch turned off the lights.

 

In any case, post back if you do find the real solution.

 

Edit:  Apologies that I didn't see the photo in the OP.  From China here, it takes a few minutes for the download, and some photos are just plain blocked.

I haven't found the solution but posting back.

The battery and taillight are one unit. Disconnecting the battery to the bike electrics does nothing and removing the battery from the bike does nothing. Taillight always on.

Strange it's happening on both bikes.

Must be a fault as the light being always on would flatten the battery over time.

Did you try searching the internet for a manual ?

 

Or, maybe it does turn off, when battery is below a level of charge.

It's a 'no name' bike I sourced from a Chinese supplier. 

But a good thought, I'll look up the motor number.

Are you still thinking about selling them ?  Specs ?

Yep getting ready to advertise them....got a great Honda CRV as well. Let me find the specifications.

I just looked at the motor: JNW11OH-20" 48V500W.

As you know I paid  US $2500 and $500 freight.

So I'd have to knock of the freight price to start with.

Will find the specs.

They weren't inexpensive, nice specs though and look good.

 

Quality ebikes are not inexpensive, for others considering.  Seems 35k-50k is standard pricing for quality, specs dependent.   Even my DIY conversion totaled up to ~25k baht, and doesn't have the suspension & brakes for the speed it will do.

Yes nice bikes but after my back fusion from T11 to sacrum I need a step thru and China supplier wouldn't come to a deal. 

Being an ebike man from way back (we worked in China for a year but just had regular bikes), what is a reasonable price I should advertise the bikes for? Thanks

Now I think it could be a design feature.
