I'm building a 48" x 24" beach wagon cart. I'll be using 30cm Wheeleez on it ( Specs attached).
Usage will be about under an hour and half, cargo weight NOT including cart or all electrical components should be under 200 lbs.
I liked this kit you designed but the weight of the batteries might be too much. I think a 350w motor should be enough
This kit looks like it would work as well with the 12 ah batteries but with a 350w motor instead.
I'd need a sprocket that fit my tires.
I do not have any sprockets that directly bolt onto Wheeleez wheels. That part of the build may take a little bit of customization to create.
I can build an electrical kit for your project like KIT-140 but with a 350 Watt gear motor. Do you want the new kit to have reverse like KIT-140 does?
How about Kit 105, with a reverse switch? Do you think a 3 350w motor would be strong enough? What would be the max weight a 350w motor would work well with? I definitely need a motor with a flat surface mount, because I'd be mounting under the carriage.
The maximum weight that a 350 Watt motor will work with depends on the gear ratio. With a low gear ratio that provides a 3-5 mph top speed a 350 Watt motor can work with a heavy load such as 600 lbs, and with a high gear ratio that provides a 10-12 mph top speed it could work with medium loads such as 200 lbs.
I made a gear ratio calculation for your project using a 30cm wheel, a 44 tooth wheel sprocket, and the 350 Watt gear motor and got a 3.03 mph top speed. 3.1 mph is considered to be the average walking speed. With a 3.03 mph top speed a 350 Watt motor will provide more than enough power to move heavy loads through sand and up ramps and inclines. Here is the gear ratio calculation:
I can make a kit similar to KIT-105 except with a 350 Watt gear motor, reversing speed controller, and handlebar mount reverse switch. Do you want a battery pack and battery charger to be included with the kit?
I am building a similar beach cart. Can you give a complete parts list to order? When I try to search Kit-105 it does not look complete, chain, sproket, controller, battery, charger, wiring.
If you find a kit that looks good for the project but you would prefer different size batteries, a different throttle, etc. then please let me know and I can make a new kit to your specifications. I can also help with gearing and sprocket size selection if there is a top speed that you would like the cart to have.
Please let me know if you have any questions.
