New! The latest version of the award-winning ESR750EX electric scooter from PMW features significant improvements to an already legendary model. 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 replace 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 13/82 sprocket ratio to take optimum advantage of the new motor for the worlds best speed, range and hill climbing ability versus electric vehicle weight. If you are looking for a longer range, reliable, powerful and compact energy efficient means of transportation, the ESR750Ex is the New Machine to keep you going. It weighs in at just 59 pounds. Featuring 'economy' mode for super long battery life, and 'turbo' mode for amazing performance, the ESR 750 EX boasts a 50% longer range than the ESR750 due to the larger batteries. All other features are identical. It can reach 20 mph, and has a range of over 15 miles per charge. It climbs hills with ease, is virtually silent, and includes an integrated smart charger.
Features:
10-inch pneumatic street tires with polished magnesium wheels, lightweight and extremely strong frame and fork, front "Mad Dog" disc brake, automatic chain drive with 13/82 gearing, folding handle bars for portability and easy storage, and a high-performance 750 watt 24 volt motor.
