California Go-ped ESR 750 with Li-lon Battery

ESR750 Li-Ion

Depending in model, the on board Li-Ion battery power consist of 2, 3, or 4ea 25.9V Li-ion polymer battery packs wired in series, one or two packs per side within the aluminum battery pan.

As the battery packs take up less room than the previous SLA (sealed lead acid) batteries in the ESRex and Hoverboard, further weight and deck thickness is also reduced to create the sleekest, lowest standing height, lightest, highest range electric portable transportation devices in the world.

New Improvements for 2008!

After several years of very successful service the "Electric Speed Racer" ESR 750 Go-Ped product line has been greatly improved for 2008.
Along with an innovative new self adjusting chain tensioner, the heart of the 2008 improvements are from a new, and much more efficient motor.
The new ESR motor has the following enhancements;

• Significantly thicker and much more powerful Rare Earth magnets.
  
• Brushes and heat producing components are now better located within the new and better heat transferring aluminum "E Head".
  
• All precision sealed ball bearings at each end of the motor shaft replacing previous brass bushings.
  
• Commutator/brush drag cut in half.
  
• Larger armature copper wire diameter for reduced resistance and unwanted heat.
  
• Higher motor RPM operation to improve efficiency.

The result is a significantly lower operating temperature resulting in significant ESR range and reliability and brush life increases. The new ESR 750 and ESR750EX come now equipped with a new 13/76 sprocket ratio and 106 chain length to take optimum advantage of the new motor for the world's best speed, range and hill climbing ability versus electric vehicle weight.

The most innovative and highest quality features and components abound in the ESR750, making it the most cutting edge, reliable and versatile electric scooter in the industry. It is the Absolute combination of True Style and Pure Freedom.

Auto-adjusting Chain Tensioner – This important improvement is based on it's earlier manual adjusting high abrasion resistant predecessor which uses the same mounting position. It now incorporates a longer and spring loaded slot with automatically consistent, yet gentle slack elimination which effortlessly stop chain derailments. The auto adjusting chain adjuster now accommodates greater chain "slactitudes" found with various sprocket combinations and changing chain conditions.  This baby is also very easy to install.
Electric Motor - After over a year of research for the most powerful and reliable engine, the ESR750 line provides for unmatched power and offers no compromises on performance. It is equipped with a robust and well proven DC brush type motor with “Electro Head” finned heat sink that is capable of producing over 1HP in continuous operation and reaching top speed of over 20mph, while offering thrilling acceleration. The high output makes it the most unique scooter able to tackle steep hills with ease.


Electronic Controller – We would have to kill you if we told you too much, but what we can reveal is that the ESR 750H Li-Ion electronic power controller is a sophisticated and proprietary pulse width modulated design. The ESR750 Li-Ion line are the only electric scooter of its kind equipped with an advanced computerized variable speed and programmable controller. With a wide variety of EPROM (Erasable Programmable Read Only Memory) programmable functions, it gives users the freedom to not only do on board diagnostics but also customize performance.
Dual Performance Modes - The operator can chose the "Econo" or "Turbo" performance mode on the throttle control to either go "twice as far, half as fast", or "twice as fast, half as far", providing users with absolute control over their choice of speed and range
On Board Charger - The ESR750 line has a very efficient on board "Smart Charger" to quickly, safely and fully recharge batteries using a separate charging chord to any 110v or 220v household power outlet worldwide.
All Lithium Ion models come with an external charger as well for a speedier charge.
Drive Train - Power to the rear wheel is through a #25 chain with tension maintained by a simple manual chain adjuster. The standard final drive front/rear sprocket ratio is 13/75 and allows for free wheeling and modifications to many available ratio combinations.

*For comparison purpose only; with 170 lb rider, full speed, non stop, no wind, no hills, smooth surface, max tire pressure.
**Battery cycle life greatly depends on DOD (depth of discharge), state of charge storage, temperature and other variable battery stress factors.
