You might try Endless Sphere. They like to get geeky over there.

Generally speaking we do not have info on directly working on the circuitboard of any display; If the display is broken I would recommend replacing it.

BBSHD does have a bit of a growl normally. You could just pull the secondary steel gear and add some lube without getting too far into the guts of the machine if you wanted to, might help, but not sure I would even do that much. I can make a video of the sound mine makes if it helps to compare.

I read on this forum that the button battery inside the apt 750c lcd cannot be replaced, that I can't solder in a new one. I made the mistake of already taking out the battery. I hope there is a way I can put a new one in. Is there?

I have the BBS02 mid-drive kit with the 52 V Luna Wolf V2 LG MJ1 13.5 Ah battery. Bought in Feburary, but after I got it installed I only rode to work a couple of times before I was assigned work at another location I couldn't bike to. Finally, I am back at my normal location and broke out the e-bike to commute to work yesterday.

Previously, I only remember hearing a slight whining noise from the motor. Yesterday, at some point I became aware of a "growly" noise. Didn't sound like grinding. Seemed to potentially get louder throughout the commute. Only happened if the motor was running. If I shut off assist and just pedal, no "growly" noise.

The kit has only ~140 miles on it. Plus maybe 20 miles or so of unpowered usage, where I left the battery at home and just rode it like a normal bike. I'm only using pedal assist, I did not mount the thumb throttle. I have not changed the stock firmware. I will say I'm not the easiest on it, I use max assist and pedal as well, typically going around 25 MPH on level ground on a decently upright bike with saddlebags.

Is this something I should open up and inspect to catch before something fails? Or does this sound like a pretty normal sound, and I'm just not remembering after not riding for all of summer?

[paxtana]

That is not a function that is built into the stock controller, so it is not realistically possible.

You'd think... but I haven't looked at one up close... I know none of my motos work that way since the handle bars bolt to the top triple clamp, but sur-ron does use a lot of bicycle parts so ya never know...

[Retrorockit]

IDK for sure if the bearing adjustment differs with triple forks or not. But straightening the stem should be the same.

[AZguy]

That's a surron with dual triple clamps, not sure if same process - admittedly I don't know one way or the other

Thank you guys for the help it worked!! One more question if you don’t mind:

I want the throttle to work only after the vehicle is in slight motion (like 3 kph or so), is this possible?

this is called a kick start in electric scooters I think, just want to know if I can enable this on the taleria to prevent accidental throttles

[Retrorockit]

If you don't need to remove it you can leave the small bolt on the top cap alone. That adjusts the bearing preload. There should be 2 bolts that go sideways through it on the back side. If you loosen those it should turn on the tube sticking up. It's designed to slip instead of break in a crash. Like Paxtana said having the bars mounted helps because this is how you align them. Get them straight , and tighten the 2 cross bolts. If that part is broken then you need to remove the top cap. Don't let the fork fall out the bottom or you might have ball bearings all over the place. Tighten the cap just enough to take the play out of the bearings (the other 2 bolts must be loose for this). Then tighten the 2 pinch bolts. You can check for play by holding the front brake and pushing the bike back and forward Too tight can damage the bearings.

Loosen headset, put it into position, tighten headset. This is probably easier if you have the handlebars actually attached to the stem when doing so. Most people would stand in front of the bike and use their legs to hold the wheel in place, then just pull the bars in whatever position it needs to go. There are probably videos on youtube showing this if needed

Please help me rotate the thing circled in the picture so it’s aligned with the front wheel. How do I do this? Thanks

[Retrorockit]

It has Regenerative Braking, that's the motor recovering energy tore charge the battery.

Why whenever I let go of throttle it feels like my brakes apply
