My Bafang Ultra Mountain Bike! Frey AM1000

If it sounds too good to be true....

Anytime you get that doubting feeling about something, it's safest to listen to it.
It was probably clearing stock in the warehouse. Take note the battery was External and not the Inner tube. It might be the older M620 motor with an old Rotor and Gear. It would help if you wrote to them to clarify your doubts.
Just a quickie tech question; can anyone confirm that the rear thru axle bolt is 12mm?
