I would say the controller being limited to 14 amps is probably correct. On my bike with the stock Amped controller and large diameter tires (26" Big Apples) and a large payload (me at 250) and one direct drive Amped hub motor I can only get up to 12 mph on the flat with no pedaling but it feels like the controller is speed limited too. At 12 mph I usually take over and pedal to go faster.
I was still happy with that because I could accelerate from stops faster and climb the hills around my house more easily.
