The Electro-Drive™ electric scooter is equipped with 
the patented Currie Technologies
® Electro-Drive™ 
propulsion system, the finest available in today’s 
rapidly growing personal electric transportation 
market.
The Currie Electro-Drive™ features a DC motor with 
direct chain drive to the rear wheel, a weather and 
dust resistant motor controller, plus rechargeable and 
recyclable sealed lead acid batteries that provide 
many hours of trouble free riding. 
The Electro-Drive™ motor and drive train system 
comes fully assembled and “ready-to-ride” from the 
factory. 
IMPORTANT: All Electro-Drive™ motors, throttles and 
the controllers are factory sealed units and are not 
user serviceable. Do not open or tamper with any of 
the factory sealed units; doing so may result in electric 
shock or injury and will render them inoperable.
For answers to service questions regarding the 
Electro-Drive™ drive train, please contact your local 
dealer, or call Currie Technologies
® Customer Service 
at: 1-800-377-4532.

Always test your brakes after making any adjustment to 
be sure they are operating properly before riding.
If you reach the limit of the cable adjustments described 
above and you are still experiencing poor braking 
performance, do not continue to ride. Do not attempt 
to adjust the cable any further or attempt to adjust 
the brake. Take your scooter to a qualified scooter 
or bicycle mechanic for proper service, or call Currie 
Technologies
® Customer Service at: 1-800-377-4532.
Proper brake performance and adjustment is vital to 
safe scooter operation. Never ride your scooter unless 
your brakes are adjusted and working correctly.
bRake oPeRa
TIon
The Electro-Drive™ electric scooter 
is equipped with front and/or rear 
brakes. It is operated by using the 
brake lever on the handlebars and is 
designed to provide excellent stop-
ping power for your scooter. Squeeze 
the brake lever(s) firmly to bring your 
scooter to a safe, controlled stop.
The brake lever itself should never 
touch the handlebar or grip when 
squeezed firmly. If it does, then immediately STOP RIDING and adjust the 
brake cable.
All brakes need periodic adjustment. However, the brake 
mechanism itself should be adjusted only by a qualified 
service technician. If or when it needs service, take your 
scooter to your local bicycle dealer or to the retailer who 
sold you the scooter.
Improper adjustment of your brake(s) can cause poor 
braking and lead to an accident, serious rider injury or 
death. 
bRake Cable aDjUsTMenT
If your brake cable stretches (as is 
common with new cables do during 
the initial “breaking-in” period), your 
brake lever will require a longer “pull” 
to engage the brake and may even 
touch the handlebar when squeezed. 
Use the adjusting barrel on the brake 
lever to adjust for this cable stretch. 
Loosen the adjusting barrel lock nut. 
Unscrew the adjusting barrel out of the lever 1 to 2 turns, then re-tigh\
ten the 
lock nut to secure the adjusting barrel. Do not allow the adjusting barrel to unscrew more than 
5 full rotations out of the brake lever.

watching the chain. Be sure that the rear wheel is turning smoothly 
and the chain does not try to run off the rear sprocket in either direc-
tion.

any necessary adjustments.

Adjusting the chain tension is performed 
by moving the motor back and forth within 
the motor plate.
1. Loosen the three 5mm Allen bolts 
that hold the motor and motor 
guard to the motor plate. (Ref Pho-
tos A, B, C)
2. Twist the motor (counter-clockwise 
to tighten the chain, clockwise to 
loosen the chain) to adjust the 
chain. Please note that a slight ro-
tation of the motor will dramatically 
effect the chain tension.
3. When proper chain tension of 
5-6mm (about 1/4”) of up and down 
movement is achieved tighten the 
three 5mm motor bolts. Do not ride the 
scooter in order to check the chain 
adjustment. It is far easier and safer to 
check the chain adjustment as described 
above. If the chain does run off the rear 
sprocket during the test, then further 
adjustments are necessary. 
noTe on CHaIn lUbRICa TIon: To  
help maintain both the performance and 
longevity of the chain,  be sure to lubri-
cate it at least once a month using any 
quality bicycle chain lube. While lubricat-
ing the chain take time to inspect it for 
any damage and for proper chain tension.

The chain can stretch during use or may occasionally come out of adjust-
ment. Regular attention to proper chain tension and lubrication will min\
imize 
the risk of the chain falling off the rear sprocket and help your scooter main-
tain optimum performance. 
Properly adjusted, the chain should have 5-6mm (1/4”) of up-and-down travel 
or slack. Currie 
Technologies
® 
strongly recommends that any chain 
tension adjustment be performed by a 
trained scooter or bicycle mechanic.

Adjusting the chain tension is per-
formed by moving the rear wheel back 
and forth in the frame.
1. Loosen the rear axle nuts us-
ing a 15mm wrench but do not 
remove. (Ref. Photo A)
2. Loosen the band brake arm 
fixing bolt, using a 5mm hex 
key wrench and an 8mm box 
wrench, but do not remove. 
(Ref Photo B).
3. Adjust the belt tensioners (Ref 
Photo C) on both sides of the 
frame equally to keep the rear 
wheel properly centered in the 
frame and so that the chain has 
5-6mm (about 1/4”) of up and 
down movement.
4. Tighten the brake arm fixing 
bolt.
5. Tighten both axle nuts.
6. Test the chain adjustment by 
rotating the rear wheel forward 
by hand a few revolutions while

The order of this installation is very important. Start with the chain p\
ushed 
over the frame so it can be placed on the large sprocket after the wheel\
 is in 
place.
1. If your scooter has a rear brake install it on the left side axle. Be su\
re 
the chain is mounted on the large sprocket on the right side of the hub.\
2. Push the wheel with the larger chain guard all the way forward in the fr\
ame.
3. Work the chain onto the small drive sprocket on the motor.
4. When the chain is in place on both sprockets, pull the wheel back in 
the frame until the chain slack is completely removed.
5. Install the left and right side chain tension adjusters and the axle 
nuts, but do not tighten completely at this time. Chain tensioners are 
mounted on the outside of the frame.
6. Adjust the chain tensioners for proper chain tension (5-6mm or about 
1/4” slack), then install the smaller chain guard on the right side of the 
frame, over the motor gear and chain with its fixing screw.
7. If your scooter has a rear band brake attach it and the brake cable 
hanger by inserting the 4mm Allen bolt through the frame. Mount the 
band brake arm on the bolt first, then the rear cable hanger. Hold the 
nut using an 8mm wrench and tighten the bolt with a 4mm Allen key 
(or Phillips screwdriver), and completely tighten both right and left \
axle 
nuts at this time.
8. If your scooter has a rear band brake attach the brake cable by first 
making sure the brake cable is inserted through the adjusting barrel 
on the rear cable hanger. Then slide the spring over the brake wire. 
Thread the brake cable through the hole in the cable pinch bolt. Next 
insert the pinch bolt (with cable) through the brake actuator arm, sta\
rt-
ing from the back side of the arm so that the nut can be tightened from 
the outside. Place the washer over the pinch bolt and install the nut. 
Hand tighten the nut only at this point.
9. If your scooter has a rear band brake adjust the brake cable by pulling 
and holding it taut with pliers through the pinch bolt, push the brake 
actuator arm forward along the wire and then tighten the cable pinch 
bolt using a 10mm wrench. Immediately test the brake cable adjust-
ment by squeezing the brake lever. When the brake is fully applied it 
should not touch the handlebar, and the wheel should spin freely when 
you release the brake lever. It may take you 2 or 3 attempts to make 
this adjustment.

If your scooter is equipped with a 
V-Brake you will need to disengage it 
prior to installing the front wheel.
Do so by squeezing both of the brake 
arms together and unhooking the 
brake noodle.
1. Place the front wheel into the 
forks being sure the axle is fully 
seated into the dropouts.
2. Install the safety washers into 
the dropouts. (Ref Photo A)
3. Install the axle nuts. (Ref Photo

in pretty much the same conditions you would expect to ride a normal 
bicycle or scooter. In fact as long as you don’t submerge the electrical 
components you’ll be fine. This means avoiding deep puddles or streams, 
that would cause the electrical components to be under water. All of our 
electric scooters are designed to operate normally if they get wet. There 
is no need to worry about electrocutions or shocks from riding in the ra\
in. 
Of course you must take special precautions when riding in wet weather 
as braking distances will be greater and handling on slippery surfaces 
compromised, as will visibility.
