A2B Metro status lights.

Hi,
Can someone tell me what the lights red/amber/green on the handlebars are supposed to indicate ?
They are all alight when I start but the green goes off when I go up hill but comes back on when back downhill or at rest. Am I asking too much of the motor or is the battery coming to it's end, or maybe this is just normal for this bike.
Thanks, Chris

Welcome fellow A2B rider. What you're seeing is normal, the battery will sag a little up hills and the indicator will show amber and red. When the battery isn't under too much load, i.e. on the flat, then it'll bounce back up in voltage and the green will come back on. Start worrying when it stays on red only for a long time. I've put 1500 charges on my frame battery in the time I've had it and had to build an external one recently as the frame one is showing its age a bit. Plus I built a better dashboard for it and made it proper pedal assist.

Thank you for the reassurance It shows nearly 41v at the battery terminals. This one has no internal battery only the rear mounted which suits me as I can take it off and lighten the load on the bike rack.

This guys page is the bible for A2B batteries I practically just copied the original frame pack design and re celled with 2900mAh samsung cells. It took a while to get it right but saved me a lot of money. Have a look here for his designs. http://grifftek.com/grifftek/Other_Fun_Projects_and_Hobbies/

Just an update which may be of use to other A2B users.
At between 5 - 6 miles the green light stayed off.
At between 15 - 16 miles the amber light stayed off.
It was still powerful.
This was doing some pedalling as well.
All things considered - It's a very nice ebike

Can you add a throttle to the A2bs that have no throttle? I ask because of the incoming laws about throttles bikes no longer being built. I reckon by the time I get the spare cash together we'll be well into that law and I need a throttle, because of my health. These bikes look like a good compromise between a full on bicycle and the moped types. I switched from moped style, which was easy for me, to a bike style which I find difficult because of the height and less road holding.

If is one of the newish ones with torque sensors, like this
