Hi C-cap,
First of all, big applause for the beautiful build - well done!
I am building my second e-bike and attempting a Nuvinci>Gates>Bafang drive system. Most everything is from my previous build except the gates drive, so I know if all else fails I will go back to the chain driven system...
I have purchased over $1500 in batteries, motor and parts and will continue to buy from Luna -they have the best service and rockin' prices. Only once did I have a defective part (a watt meter) and Eric sent me a new one, no questions asked and I received it a couple days after contacting Luna...
I just bought one of the Luna triangle bags (the zip tie version) and I am pretty happy with it. It seems well constructed, the battery fits nicely and it hangs securely in the bike's triangle (no slopping around). Unfortunately the zipper broke after a week's worth of riding. I think it is...
