I don't know what you're going on about. Yes, it is that A2B Metro. Yes it's 10 years old, and yes I just put a band new battery in it. Can we get back on topic or should I just delete this thread due to all the rambling. I have maintained this bike thoroughly and has never given me any...

No it's brand new. I'm on my 4th battery. That's why I know it's not the battery. Gonna take the bike apart and look for loose connections.

I don't have one but probably about 500 miles.

I have an A2B Metro and I use it almost every day, and lately the bike will just shut off when I hold down the throttle for like 5-10 seconds. So now, basically I can't go fast because it will shut off, and when it happens, I have to turn the key off and then turn it back on, and everything will...

Oh wow, thanks for the links! I wasn't having much luck last night finding anything. I just noticed the tip of the charger plug was missing a screw so I took the other one out to see if any wires were loose and was met with this...

If I plug the charger into the wall, and then plug charger into battery, it just still flashes. Even if I plug it in the opposite way, still just flashes. Even when the bike is not connected to the charger, and I just plug the charger into the wall, the charger still just flashes red/green.

Bought a used A2B Metro but the charger just flashes red and green regardless of it being plugged in or not. Anyone have any idea why? This is my first e-bike so I'm kinda new to this but so have electronic know how. I'm just not sure where to start. It also does not show any lights by the...
