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.
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 13/75
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.
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.
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.
- After over a year of research for the most powerful and reliable
engine, the ESR 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.
– We would have to kill you if we told you too much, but what we can
reveal is that the ESR 750 electronic power controller is a
sophisticated and proprietary pulse width modulated design. The ESR750
is 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. Economy has up to a 8+ mile range while
Turbo Mode gets 5 miles.
On Board Charger
- The ESR750 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.
- The ESR750-EX uses four 12 volt SLA (sealed lead acid) batteries. Two
on each bank of the pan are wired in series, and each bank is wired in
parallel to create an effective 24 volt, 11 amp hour power supply.
- 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 15/76 and allows for free
wheeling and modifications to many available ratio combinations.
Chassis and Frame
- The patented single tube frame/chassis is based on the cantilevered
aircraft grade chromoly carbon steel frame so well proven by the
lightest and highest performing racing Go-Peds.
oversized Go-Ped® renowned quality frame also incorporates the motor
and simultaneously serves as a heat sink to help dissipate the heat
generated by the motor, which offers top reliability and range design
- Its front fork, also made of aircraft grade Chromoly Carbon steel, is
the well proven and patented cantilevered design for simplicity, low
weight and ease of maintenance. To the fork is mounted the Brand New
and Ultra Powerful “Mad Dog” disc brake caliper, which is an
international standard mountain bike style, with tempered stainless
steel “wave” disc rotor, provides for exceptional braking performance,
control and safety.
- The polished wheels are made of strong, but very light weight cast
Magnesium alloy, and have very low rolling resistance "TT" style
treaded pneumatic tires, 10 inches in diameter, which contributes to
the most comfortable ride.
Platform - Deck -
The standing platform or "deck" made of beautiful light weight Latvian
Birch plywood from Lithuania combines the best attributes of a low deck
height and excellent ground clearance of any electric powered scooter
available. This creates the friendliest, and easiest to use ergonomic
"magic carpet" possible.
patented and gracefully formed low profile aluminum battery pan below
the platform serves as an ingenious mount and provides for excellent
protection of the batteries, electronics and wiring.
pan/deck electronics battery pack is weather resistant and factory
sealed. It can very easily be removed and replaced from the frame with
four mount screws on the top of the deck and by disconnecting the
electronic control quick-connects, and motor power leads.
The rear wheel, chain drive system and rider are protected by a stylish
single piece rear fender made from injection molded and ultra resistant
polypropylene thermoplastic. Its beautiful, well thought out design
gives it a customized and unique motorcycle look.
Handlebars and Controls - The
handlebar control system is of 6061-T6 aircraft aluminum alloy and is
classic Go-Ped®, down to the elegantly simple, convenient and highly
imitated yet never surpassed folding spring loaded locking sleeve
brake lever and two position power ON/OFF button is ergonomically
designed and easily accessible on the left handle grip. A smooth
variable speed thumb throttle with Econo/Turbo selector and three LED
battery condition fuel gauge like "Flux Capacitor" on the right grip
allow users easy control of their ESR 750 and the ability to know at
all times the power level in the batteries.
