Road Legal N1 Homologation

Lead-acid / Lithium Batteries

Range 50- 101 miles

The Goupil G4’s modular design lends itself perfectly to a host of body conversions, if you cannot find a body option in our standard range the G4 Chassis Body provides a blank canvas to build your ideal vehicle. Built from the ground up as an electric light commercial vehicle, the road-legal G4 produces zero-emissions, homologated to N1, and comes with a choice of lead-acid and lithium batteries.  With the added option of left and right-hand drive, the G4 along with its robust ladder frame construction can be built to your exact requirements.  Examples of bespoke bodies built on a G4 include cherry pickers, gritters, tail lifts, cranes, refrigeration units, bike racks, and fire fighting equipment to name just a few.


The G4 incorporates electronic regenerative braking under deceleration with proportioning electric braking.  The dual-circuit hydraulic brake system comes with front disk brakes and rear drum brakes, and hand-operated park brake with a torque-limiting sensor.

A high/low-speed switch with two-speeds; 6.5 and 31mph give operators control to reduce the vehicles speed restricted sites to prevent over speeding.

The G4 incorporates a safety seat cut out whereby the vehicle will not operate unless the driver is seated.

Outstanding Performer

The G4 is extremely versatile, it’s compact dimensions, and low gross vehicle weight allows the electric G4 to access restricted areas and pavements while at the same robust for heavy-duty tasks.

The G4 chassis body has a payload that outperforms many mainstream vehicles in its class.  The steel cataphoresis coated, robot-welded, ladder frame has the strength to carry heavy payloads, with a 2100kg GVW the G4 9kW lithium model can load an impressive a 1370kg on its chassis.

A comfortable Working Environment

The G4 provides a safe and comfortable working environment. The lightweight aluminium cab is protected with polypropylene bumpers and includes ABS glass front and rear screens with electric front wiper, screen wash and electric heated front windscreen.

Both driver and passenger have adjustable seats and padded adjustable headrests and afforded excellent all-round visibility with a rear cab window and fully glazed doors with views of pavement and kerb.

The instrument panel incorporates a high-definition LCD colour display which includes battery discharge indicator, digital speedometer, odometer and low-level warning lights.

Ride and Handling

Constructed with McPherson suspensions at the front and with composite blades at the back, a double circuit brake system produces a comfortable ride.
Responsive acceleration comes from a 48-volt Curtis controller and reaches a maximum speed of 31mph, and handles gradients up to 30%.


Unlike many electric vehicles, the G4 doesn’t require any additional and expensive charging infrastructure. With an onboard charger, the G4 can be charged via the mains socket.
Available with either lead-acid or lithium-ion, there are two battery sizes to choose from, ensuring the right battery size and technology is paired correctly to the application.
