Assuming a constant acceleration, which it is not, that's 0.74 g's.
I.e. the driver has to pull horizontally on his handlebar with a factor of 0.74 times his complete weight.  Considering that the torque curve varies, there must be a peak G that is much higher. 
Of course, the seat helps too.  But it muste be a good kick in the butt.
Practice lots of chin-ups before attempting a drive...
