Determine what rear wheels, axle, and sprocket types the project will have.
2-Wheel Drive: Beach carts and beach wagons that will be used in the
sand or off-road will need to have two wheel drive with the motor powering both
of the rear wheels through a live axle otherwise there will not be enough
traction. If the project already has two rear wheels powered by a live axle then you are all set and just need to measure the wheel's diameter
(distance from bottom to top of the tire).
If the project does not yet have two rear wheels powered by a live axle then that part of the project will need to be sorted out
before moving forward. If you are starting from scratch then go-kart wheels, axles, and axle
mounting parts are
most commonly used for these types of projects and they can be obtained through online go-kart parts stores.
Freewheel or Fixed Sprocket: There are options for having an axle sprocket that freewheels so the beach
wagon or cart can be pulled without any resistance from the motor. When a
freewheel is used then the motor can operate in the forward direction only and
the wagon or cart cannot have reverse. Beach wagons and carts with freewheeling
sprockets sometime have mechanical brakes if they will be used to go down hills.
Another option is to have an axle sprocket that is fixed to the axle and does
not freewheel, with this option a kit with reverse can be used so the motor can
power the wagon or cart in both forward and reverse directions. A fixed sprocket
will also allow the motor to provide braking to help keep downhill speeds
Motor or Mechanical Braking: When a fixed sprocket is used the motor
will provide quite a bit of braking power when the throttle is released and the
motor will hold the beach wagon or cart still on flat ground for parking. If a
beach wagon or cart needs to be brought to a fast or complete stop when going
downhill then a mechanical brake may need to be installed. If a freewheel
sprocket is used then a mechanical brake may need to be installed to slow down
or stop the beach wagon or cart when going downhill. Lightweight beach wagons
and carts with light load may be able to be slowed down and stopped by hand when
going downhill so a mechanical brake may not be needed.
Get to Know Our Sprockets: Both freewheel and fixed sprocket to axle options can be explored on our
Sprockets Page and it is good to get to know the sprockets
that are available before using the calculators in step 2.
Get to Know Our Gear Motors: It is also good to get to know the gear motors
that are available on our Motors Page before using the calculators in step 2. To obtain the proper
gear ratio and top speed, gear motors need to be used for electric beach wagons
and carts. Gear motors are motors with a gear reduction transmission built into
them so their output shaft spins at a significantly lower speed than a standard
electric motor's output shaft spins at.

Gear It for Your Walking Speed: The average walking speed for most
people is around 3 MPH, however, many people who have geared beach wagons and
carts for a top speed of 3 MPH have found it to be a little too slow and have
regeared them to go around 4 MPH. Do not be tempted to gear the beach wagon or
cart to go faster than walking speed otherwise it may not have enough power.
Don't Confuse Torque with Horsepower: Electric motors need to be
running at their fastest speed in order to produce the most amount of power.
Electric motors have a high amount of torque at all speeds however torque x RPM =
horsepower, so the motor needs to be spinning at its highest RPM in order to
produce the most amount of horsepower.
Step 2: Determine the motor power requirement,
gear ratio, and sprocket sizes using the
Drivetrain Parts Selection Guide.
Step 3: Determine the Voltage of the required motor by looking at the available kits and then estimate the battery pack Ah rating using the
Battery Pack Ride Time Calculator.
For beach wagons and carts we recommend selecting "Flat with Some
Hills" or "Mostly Hills' in the calculator and think of hills as
being sand which can likewise require a lot of power to drive
Step 4: Use the worksheet below to record the calculated and
estimated parameters and use the worksheet to narrow down which kit
and sprockets to use.

Step 6: If you found the perfect kit for your project however need it with a smaller or larger battery pack, different style throttle or switch,
or without an included sprocket, then request a kit modification using our Kit with Alternative Part Request Form.
