Hi Tiha,
It seems that upright sitting position and "normal" handlebar help a lot.
Other negative-trail bikes seem easy to learn also,

Perhaps a more upright python may be easier to learn. Seat angle can be
lowered with more experience. Not sure if handlebar would help learning
python, gloves and sticks do. Handlebar on python seems to be good for fine
control at high speed, beyond what the legs can do...

but friction isn't a conastant ratio, and the angle the steering bar has for a
certain steering angle will change every time. maybe the steering bar is
sometimes allready like full conrering, but you're still going straight. The
clamped pullies prevent such situations as long as they don't brake.
