    A stand-up, rapid response, electric utility vehicle.
  • The Chimp moves personnel (and some cargo) through various indoor and outdoor environments. 

    Traveling at up to four times walking speed, it can quickly pay for itself from labor cost savings alone.

    Designed to fit through standard doorways, and into limited access areas; the Chimp is ideal for warehouses, industrial complexes, airports, campuses, amusement parks, and security patrols.

    The Chimp¡¯s soft plastic body was specifically designed for pedestrian safety, for use in "people" environments.

Target Markets:
  • The "soft" security market -  Anywhere security and safety is needed around people.

    This includes parking lot patrols, amusement and theme parks, downtown and beach pedestrian areas, malls and shopping centers, campuses, events, etc.
    (The Chimp's soft plastic body could give an occasional nudge without serious complaint as it creeps and weaves through crowds of people. 
    Steel bodied vehicles can shatter bones.)


  • Industrial markets:
    Security patrols
  • Recreational rentals.

Target (competing vehicles):
see comparison spreadsheet below




Unique and
Beneficial Features:
  • People soft and safe one-piece plastic body, with integral wheel-wells, storage, and "padding" for operator comfort and safety.
  • Roto-molded body is color-impregnated (no painting), hi-impact strength, never dents, and is scratch resistant
    (scratch it, and it's still the same color).
  • Body can be removed in less than 30 seconds. 
    The batteries could be swapped-out in minutes
    (this could be very beneficial in rental or multi-shift operations).
  • Many safety features including: charger interlock (cannot be driven while plugged-in); regen braking (feel of compression braking on downhills or slowing down, and roll-away is reduced to creep speeds); downhill speed limiting; timed shutdown after 3 minutes of non-use (time programmable); low-volume reverse beeper; etc.
  • Driver fairly well protected from low-speed collisions, even from the rear (an important feature for parking lot duties)
  • Very stable. 
    (which are located as low as possible in the vehicle) provide incredible ballast.
    Impossible to "wheelie" with front wheel drive.
    "If you get in trouble on this vehicle; you were lookin' for it."
  • Plastic battery tray designed into the body mold, and cut from what would have been scrap.
    Impervious to acid - protects frame from rust-through which is a common problem to all other industrial vehicles. 
    Powder-coated frame also prolongs its life
    (compared to paint).
  • Incredible range:  Pulls about 20 amps at cruising speed.  Can travel over 30 miles on a charge.
  • Easy and intuitive to drive.  You won't need lessons before jumping on it and driving it away (compared to 2-wheel balancing types).
  • Tested and proven product.  Well over a year of every day use with several target customers.
  • Very inexpensive, off-the-shelf replacement batteries.  Easy to find anywhere in the world. 
    Projected battery life 3 to 5 years.
    Typical replacement cost:  $70 to $150 each retail;
    depending on quality and source
    (uses two batteries).
  • This is not a disposable junk, wimp-mobile, that is commonly marketed.
    This is a Made In USA tough vehicle, built for the industrial market, using the best quality components that will last for years in harsh use.
  • Has a higher perceived value than any other vehicle in its class (industrial vehicles).
