Do you want the cart to go forward only, or have forward and reverse?
Thanks for that information. I switched it from a 450 Watt motor to a heavy duty 600 Watt motor to handle the extra weight of the food. At walking speed the 600 Watt motor will be able to easily handle the weight of the food and be able to climb ramps and hills when needed.
The 3-4 hour run time will require a lot of battery capacity so the wagon will need to have three large batteries. I ran some gear ratio calculations and found that with the 10" tires it will need a 45 tooth wheel sprocket. Here is the gear ratio calculation:
We can supply all of the electrical components. The #420 chain and 45 teeth sprocket for #420 chain can be purchased from almost any motorcycle parts store.
Right now finding the right throttle for the wagon is my next goal. I have a couple of questions:
Of course you are welcome to use the 450 Watt or 600 watt motor instead, these parts are only my first suggestion.
How does this parts list sound. Would you like for me to make a kit out of the parts listed above, or make any changes?
Please let me know if you have any questions or would like any changes made to the kit.
