try a local bike shop.  they can get you want you need.  It shouldn't cost much.

Has anyone found the specs in the meanwhile ?

I also need to buy new spokes for my radwagon 3.

Customer service from RadPower keeps sending me spokes for the Radwagon 4 altough I replied several times I need spokes for the 26" wheel.

Ive got about 1600 miles on my Rad Rover and it has been flawless until today. While my PAS works fine, my throttle feature totally died. The connections seem ok and I believe it might have flashed error message 24 or something like that. Bad controller?

Green on the charger means that it thinks the battery is charged, and the charging cycle is complete.

What do the LEDs on the battery look like when you press the test button?

The key must be inserted and turned to the ON position.
In this photo Red/Grn/Grn/Grn means it's fully charged.

yes identify which battery and which rad bike you are using.

add photos to help identify the year and model. also photo mileage.

Is it a brand new or used battery pack?

I had something similar with my 2016 Radrover 11.4Ah battery.  I accidentally plugged in the wrong charger and burnt the internal fuse.  The battery pack worked as normal powering the rover; but, I couldn't charge the pack (same green light).  I had to take the battery pack apart and replace the internal fuse to get it work as normal (I think it was a mini 5amp).

I don't know if the newer battery pack have an internal fuse like the old ones?

Hi, ordered new Rad charger because I lost mine and was pretty sure the battery was dead. Received new charger today and when I plugged into the wall the light on charger is green and not red. Anyone experience this happening before?  Thanks

I'd at least get some primer or a close-enough match on the rusty parts just to slow down the rusting, while you're looking for a proper colour match.
