Primary Engine:
Electric Motor
Peak Power:
Typically in the range of 3-5 horsepower (continuous), with higher peak output depending on motor and controller configuration. Specific output figures are not provided in the product description but are detailed within the manual.
Top Speed:
Limited by LSV regulations, generally around 20-25 mph (32-40 km/h). Precise speed governor settings would be detailed in the manual.
Fuel System:
Battery Electric Vehicle (BEV). Utilizes a high-voltage battery pack for energy storage.
Battery Type:
Typically Lead-Acid batteries in these early models, though some might have offered or been retrofitted with NiMH or early Lithium-ion. The manual would specify the exact type and configuration for each model variant.
Battery Voltage:
Typically 36V or 48V battery systems.
Charging System:
On-board charger, typically requiring connection to a standard household electrical outlet (e.g., 110V/220V AC). Charging times vary based on battery capacity and state of charge.
Overall Length:
Varies by specific model (e.g., 2-seater vs. 4-seater, short vs. long bed). Typical range would be around 7-10 feet. Detailed dimensions are in the manual.

Not applicable in the modern sense of smartphone integration or internet connectivity.
Service Intervals:
The manual will detail recommended service intervals for key components such as battery checks, brake inspections, tire rotation, suspension lubrication, and motor/controller diagnostics. Typical intervals might be annual or based on mileage (e.g., every 6,000-12,000 miles), but specific guidance is crucial.
Brake Fluid Type:
Likely DOT 3 or DOT 4 brake fluid. The manual will specify the exact type and capacity. Brake fluid should be checked and replaced per manufacturer recommendations.
Lubricant Specifications:
Specific lubricants for wheel bearings, suspension pivot points, and potentially the drive axle reduction gear will be detailed in the manual. These may include multi-purpose lithium grease and specific gear oils.
Coolant Specifications:
Electric vehicles generally do not have traditional engine coolant. Battery thermal management systems might use a coolant, but its type and specifications would be detailed in the manual if applicable.

Regular checking of water levels (if applicable for flooded lead-acid batteries), ensuring proper charging cycles, and monitoring battery voltage. The manual will have specific procedures for battery care and replacement.
Brand Heritage:
GEM (Global Electric Motorcars) was an early pioneer in the LSV market, established to produce street-legal, low-speed electric vehicles for localized transportation needs. The brand has gone through various ownerships, including Chrysler and currently Polaris Industries.
Model Evolution:
The e825 was a core model in the GEM lineup, representing a more enclosed and utility-oriented design compared to earlier open-air GEM vehicles. It was designed for greater passenger comfort and some cargo carrying capability.
Production Period:
2002-2004 for the specific models covered by this manual. GEM vehicles have been in continuous production with evolving designs and technologies since the late 1990s.
