Motor braking is only available with our brushless controllers and it its braking force is mild to moderate so it needs to be used in conjunction with a mechanical brake. The least powerful brushless motor that we carry is 1800 Watts and these kits start at around $530.00 with reverse.
A 500 Watt brushed motor could achieve 15 MPH under the condition which you described and 500 Watt brushed motor kits start at around $320 with reverse.
We do not carry motors with belt cogs over 250 Watts and for a 15 MPH top speed, a 500 Watt or larger motor would be needed so that would point toward using chain drive. Without the noise of a gas engine the chain becomes the loudest part of the vehicle so although the go-kart will be quiet compared to one with a gas engine, however, the chain noise will be noticeable and will be the loudest part of the go-kart.
When dealing with smaller tires like that the top speed difference between a 10" and 13" tire is around 30% so we will need to narrow down which tire size will be used before running any top speed calculations to figure out the sprocket sizes.
Here is an example of a 500 Watt go-kart kit item # KIT-137-B:

And here is an example of a 1800 Watt go-kart kit item # KIT-481800-16:
https://cart.electricscooterparts.com/48-volt-1800-watt-electric-go-kart-power-kit-KIT-481800-16
Both of the kits above have battery packs that will provide a ride time in the 30-45 minute range. We can make new versions of these kits with larger batteries for a longer ride time.
Please let us know your thoughts and we can take it from there.
Thanks for the response!!
Re:Tires
What is the the overall the height of your listing: "4.10-3.50/4 Heavy-Duty All-Terrain Knobby Tread Electric Scooter Tire" ?

I'm using an old, manufactured, heavy, 2 seater kids kart frame that was previously gasoline powered. I have plenty of space to mount motor, batteries and controls.
To begin the process of creating a custom kit we need to ask a few questions about the design goals for the project:
- What is the top speed that you would like the cart to travel at? 3 to 15 mph
- Will the cart be designed for flat ground use only, or will it need to be able to moderate climb hills or grades, or steep hills or grades? flat to very slight grade
- What type of terrain or terrains will the cart be used on? (pavement, dirt, grass, beach sand, etc.) Grass and dirt
- How many minutes of run time, or how many miles, would you like the cart to go for on a single charge of the battery pack? 30 min to 1 hour.
- How much weight will the cart need to be able to carry? approx. 200lbs
- Do you know what the diameter of the cart's drive wheels are or will be? 10 > 13 inch overall tire ht.
ALSO: Utilize motor brakingQuiet operation (toothed belt? Or chain?)
Reverse switch
Speed control: either variable or switchable
Limited budget
Thanks,
