I'm looking to power a 6 wheeled beach wagon that weighs about 65 pounds and will carry 2 toddlers. I need help coordinating the speed control, 24 or 36 volt motor and charger. If anyone has built one of these I would love to hear what you have done, any help is appreciated.
We can help with determining sprocket sizes for the top speed that you want, and with battery sizes for the run time that you want the cart to have. We can also custom make a kit with all of the parts that you want once we get everything sorted.
If you would like help with the sprocket and battery sizes then please let us know and we will take it from there.
I ran the same calculation with our MOT-36650PL 36 Volt 650 Watt planetary gear motor and the top speed is only around a half mile per hour more with it so a 60 tooth axle sprocket will work great with either of these motors. Here is the calculation with the 650 Watt motor.
With a 37 tooth sprocket the top speed would be 5.32 MPH with the 600 Watt motor and a little faster with the 650 Watt motor. Anything over 5 MPH is considered jogging or running speed and not walking speed so I am not sure if you want it to go that fast. Here is the calculation with 37 tooth axle sprocket and 600 Watt gear motor.
Since a throttle for 1" handlebars is needed we will need to make a new kit because none of our existing kits have that size throttle included with them.
I am not sure what size batteries you would like included with the kit. Do you have any thoughts on battery size? We can help choose the right size batteries if you could let us know how much run time is needed, and if it will be used on mostly flat ground or to go up and down a lot of hills?
If you want the cart to have more than a 25-30 minute run time though then I recommend 12 Volt 22Ah (around 1 hour run time) or 12 Volt 35Ah batteries (around 1-1/2+ hours run time). What are your thoughts on this? Is a 25-30 minute run time okay, or would you prefer a longer run time in case it needs to make two trips in one day?
Just a note, batteries get heavy fast. I have 35AH batteries and it adds 50lbs to the wagon.
I would like to move forward with something that would go up to 5 mph and have a 1 hour run time.Please let me know.
Here is a preliminary parts list for the kit:
I need to ask a few more questions to finish the kit.
What type of power switch would you like the wagon to have?
Do you need a new chain and master link? If yes then how many links?
Is forward only okay, or do you want the wagon to have forward and reverse?
Okay that sounds great. I went ahead and changed the parts list for the kit as follows:
Is a toggle switch okay for reverse? Or do you prefer another type of switch for the reverse switch?
