The wiring on the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA will be 10 to 12 gauge. I prefer the Deka 10 gauge # 10-1-1 (sold by foot) paired with the Deka Heat Shrink Butt Connectors # DW05745-5 to complete the install.

There is a way to carry your 53 lb ebikes on the back of your trailer, though the Swagman Around the Spare Deluxe 2 Bike Rack for RV Bumpers # S80501 has a 35 lb per-bike capacity so it would not work.

The 1,200 Reese Strait-Line Weight Distribution System w/ Sway Control item # RP66084 is going to be over capacity for a 500 lbs - 800 lbs tongue weight and it will be pretty stiff and uncomfortable to drive. view full answer...
The tire you were looking at the Taskmaster 5.30R12 Radial Trailer Tire item # TT53012C is the only 12" tire we have with an M speed rating. We do not have any tire wheel combos that will give you a speed rating of M in the 12" size. Our tire wheel combos do not come balanced and most trailer tires do not because they are not required to be. I have linked our selection of 12" 5 on 4 1/2" lug nut pattern wheels.
We do sell a balancing kit it is the Counteract Tire Balancing Beads for Tandem... view full answer...
