So now you know the most that controller is allowing through and is putting out is 1056 watts, split that by 2, each motor is getting 528W
Still good, and the advantage is one wheel loses traction the other one can still carry the bike. Just remember the front wheel doesn't have that much weight on it, so imagine a front wheel drive car with the engine in the rear and the trunk up front, there is some fluff in the specs and design, still a good bike.
I wish Juiced would admit what it is, they are fully in production, they know, they just don't want to say.
And there are only 2 reasons, either it's too low or too high(legal issues in some States)
Some bike shops sell after market upgrades to get it the power output up there, the only downside is the battery is going to run down much faster.
Here is an example for my bike, but I am not upgrading.
