If you have a broken spoke on your Gen 3 eBike, you can source spokes here:

 

USA -

ProWheelBuilder.com

 

Canada - 

GRIN Technologies

 

The spoke you need are 12G spokes with 5mm eBike nipples. For the length, you will want to measure on of the spokes from your bike as parts changes could have been made during production and these could result in different length spokes being needed for your bike.

 

DS - Drive Side or spokes going from the right hub flange (as you sit on the bike) to the rim

NDS - Non-Drive Side or spokes going from the left hub flange (as you sit on the bike) to the rim
