I don't believe any 1000W E+ will go on its own 35mph, with crazy pedalling maybe.
You must remember that that due to faulty software alogarytm Eplus displays accurate speed up to maybe 15mph, behond that is displays 2,3,4,5 mph faster than it goes.
I verified it 3 times with GPS.
On two different Eplus 1000W drives.
