Spend $6700 on the newest RION hyper scooter or…..
You can always get a battery that has a harness and is mounted on the steering column. Increase your battery by 33%
Get Hubs with higher voltage and a lithium battery to match
Add a steering dampener (two of them)
Wide tires for traction
and a helmet hahah
Your getting the jolt because of a P setting regenerative/electronic brake strength and Acceleration combined.
The regenerative/electronic brake strength helps your battery last longer with a higher setting but the motors basically switch to reverse and it slows you down faster.
The acceleration .. I only adjust for snow and rain so i do not spin out taking off
Now the lights and horn… well this light is $11 and bright enough that it lights up my whole lane and 10 feet in front of me…but be gentle putting it on.. hand tighten only… keep super glue near by lol just incase your over zealous.

This is the horn / alarm I have… and I LOVE IT. About $60 if you get off this site direct from the China manufacturer. It is a car horn with a button and two remotes. There are 3 sensitivity settings for the alarm. (lvl 3 if I touch my tire it goes off and its not even touching my tire)
