1. The adapters, if I understand correctly, are for the calipers if you run a larger disc than the one the frame is built for. They position the calipers so they'll fit the larger disc, so you'll need one (or more) for each wheel where you'll be running a larger than standard disc.
2. I'm...
The folks at Gravity really bent over backwards to help us out, agreeing to sell us an M10 without wheels, and providing a nice discount. It's en route from Spain, and spent a lovely weekend at a FedEx facility outside Paris.
That may be wise, if I'm reading the same threads you are.

Here's where the build stands after the weekend: pretty much done with the motor and battery test configuration except for temporarily routing the wiring harness. I won't screw around with the 3-speed until my tire issue is sorted, and the battery is in a race against time with our 8/1...
But you'll need all of them. Handlebar, grips, brake levers, fork, wheels, cassette, discs, brakes, derailleur, chain wheel, crank arms, pedals, & chain off the top of my head.
Sorry. Missed that bit. I ordered from Luna. Their price was right, and they had all the bits I wanted. Besides, if you're joining the Bafang club it's probably a good idea to be Team Luna.
So far, so good! I got the non-drive side of the bottom bracket sealed cassette free, but had to drag the frame over to Green Lizard to get help with the drive side, as my bracket tool from Amazon is an ill-fitting piece of crap.
I cut up an inner tube and hot glued three strips across the...
Getting the right bike first is key.
If I had it all to do again I'd probably have waited for something with a nice front suspension and 26" wheels (so much easier to build around and find parts for). A tapered head tube and modern dropouts would have made life easier, too. That aside, we'll...
Don't confuse the wattage rating of your motor with the watt-hour capacity of your battery. If the motor draws 36v and 20a continuous then you need a 36v battery capable of 20a continuous. Battery capacity is a whole other issue.
Sworn off Home Depot forever, but yeah... I'm sure there will be some running around this weekend, because I'm certain I have everything I need, and I'm frequently wrong about that kind of thing.
I ordered from Luna, and picked up a 52v smart charger, as well. If I can have it all-but-battery...
Everything is here but my battery, which is in a race against time with my 8/1 departure date for the Outer Banks. Got till then to empty my bottom bracket, mount the BBSHD, arrange all of the accessories, and work out basic cable management. If I could bomb around the beach with it for a week...
OT, and late to the party, but I just ordered a nice custom triangle battery pack (14s6p 52v18Ah with 30Q and 40v BMS) from Electro Bike World, and they were really patient and helpful. We'll see how the results look in 10-14 days.
Say, how was your experience with Grin Tech? I'm thinking about ordering the Boy's hub motor from them, and sent an email on Friday outlining the requirements (no PAS, no display) and a rim that will take a 20" Plus tire. Haven't heard back yet, but hoping to today.
