sourced thirty-two, 3.2-volt, 300 Ah,
lithium-ion batteries and situated
them in the modified chassis. Scott
Smith of High Point Solar took care of
the wiring duties.
Yes, the car is heavy now, weighing
about 2000 pounds, but McCoy has
no interest in jumping the Rhino or
even going fast over bumps or rocks.
In fact, most of Dave’s riding is at
about 15 mph, although the Rhino is
capable of going in excess of 70 mph.
McCoy likes to travel at the slower
speeds and enjoy every inch of the
trail looking for things to photograph.
To date, Dave’s longest journey was
over 60 miles, and he drove back to
his house with having only used 3/4
of the battery life. They estimate the
current range to be around 100 miles.
Recharge time is five hours and can
be done at a 110- or 220-volt power
source. There is no backup power system installed yet, but Dave is usually
followed on longer rides by friends
and family in gas-powered UTVs.
We went on one outing with Dave,
and the E-Rhino was impressive to say
the least. Acceleration was instant,
and it literally pinned your back
against the seat. The 8-inch-diameter,
122-pound AC50 motor produced 73
horsepower and 110 foot-pounds of
torque and cost $4500 apiece. We did
have a chance to climb some sand
hills and experienced the E-Rhino’s
incredible power. Of course, that kind
of driving wears the batteries down
quicker. With one or two motors in
service, you can modulate the throttle
very smoothly and consistently. But,
having the ability to use them sepa-
rately over certain obstacles allows it
to work great in the really tight stuff.
The e-Rhino is a work in progress, but
definitely more impressive than what
we have seen come out of the off-road

Dave McCoy built an all-electric Rhino conversion from the ground up to help him
explore the country around Owens Valley in California. It’s the latest in a series of
mammoth-sized projects he’s been involved with during his life.
Dave is a true pioneer of adventure
sports, and his latest hobby for well
over a decade is enjoying the dirt
trails in Owens Valley, California, with
his wife Roma, kids, grandkids and
Charging time is five hours and can be
done through a standard household
110-volt system or at an e-car charging
station using 220 volts.
This is the rear AC50 electric motor
producing 73 horsepower and 110 foot-
pounds of torque. This thing would give
the new turbo RZR a run for its money.
