I'm looking for the best cheap setup with a list of absolutely everything I need to order (with links if you can). I'm looking to equip me and my friends so we can night ride for 1.5-2 hours and be happy about riding at night.

So far my research would have me guess 2 of these battery packs. This charger. Maybe a Yinding for the bars? And that's kinda of where I'm at so far. I guess I still need a helmet light, mounts for both lights, and an extension cable to put the helmet battery pack in the jersey back pockets (right?).

I'd greatly appreciate some help. Thank you!

P.S. If it works out, I could compile a starter kit list that we could sticky on the board.
