I have a 13 year old disabled son who likes to hunt. He currently has a chinese 100cc gasoline atv that we would like to convert to Electric so he can use it to get from our base camp to his deer blind more quietly. We can't afford a $12,000 track wheelchair so I thought this would be a good option. This is all new to me but I am trying to learn.
What info would you need from me to help me get the right setup?
I'd like atleast a 1 hour run time for him. He weighs about 100 pounds. He likes to go fast when he does not have to be quiet.
The atv has 16x8-7 tires which I think is 51 inches around.
I would say that the ATV can go slow and be able to climb steep hills. Walking speed or a little fast would be good.
ESP Support, Any ideas on this?
The MOT-36600G gear motor has a 10 tooth sprocket for #420 chain. The axle sprocket would need to have the right number of teeth and work with #420 chain and a #420 chain used between the motor and axle sprockets.
Most ATVs have either #420, #428, or #520 chain and sprockets. The difference between these chain sizes is their pitch and width. #420 sprockets have a 1/2" pitch and are 1/4" wide, #428 sprockets have a 1/2" pitch and are 5/16" wide, and #520 sprockets have a 5/8" pitch and are 1/4" wide.
If the ATV has an axle sprocket for #420 chain with 48 or more teeth then it can be used with the 600 Watt gear motor, otherwise a new axle sprocket would need to be sourced for the project.
While you are working on the axle sprocket side of the project I can begin calculating what size battery pack will be needed. How many minutes of run time would you like for the ATV to have?
We do not carry sprockets that fit 350 Watt electric scooter motor which are larger than for #25 chain. The easiest way would be to install a sprocket for #25 chain on the axle.
We can calculate the gear ratio and axle sprocket size if you could let us know the diameter of the ATV's rear tire, and the number of teeth on the motor sprocket? Also do you want to use the ATV on primarily flat ground, or to go up hills and through mud or sand?
Regarding battery size, how many minutes of ride time would you like for the ATV to have?
Would 1.5 hours be unrealistic for my project?
