After several years of very successful service the “Electric Speed Racer” ESR 750 Go-Ped product line has been greatly improved.
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 ESR750EX come now equipped with a new 13/75 sprocket ratio and 110 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.
