Before You Ride
About this Manual
It is important for you to understand your new bicycle. By reading this manual
before you go out on your first ride, you will know how to get better performance,
comfort, and enjoyment from your new bicycle.
It is also important that your first ride on your new bicycle is taken in a controlled
environment, away from cars, obstacles, and other cyclists.
General Warning
Bicycles can be hazardous activity even under the best of circumstances. Proper
maintenance of your cycles is your responsibility as it helps reduce the risk of injury.
This manual contains many “Warnings” and “Cautions” concerning the
consequences of failure to maintain or inspect your bicycle. Many of the warning
and cautions say “you may lose control and fall.” Because any fall can result in
serious injury or even death, we do not repeat the warning of possible injury or
death whenever the risk of falling is mentioned.
A Special Note for Parents
It is a tragic fact that most bicycle accidents involve children. As a parent or guardian,
you bear the responsibility for the activities and safety of your minor child. Among
these responsibility are to make sure that the bicycle which your child is riding is
properly fitted to the child; that is in good repair and safe operating condition; that
you and your child have learned, understand and obey not only the local motor
vehicle, bicycle, and traffic laws, but also the common sense rules of safe and
responsible bicycling , As a parent, you should read this manual before letting your
child ride the bicycle. Please make sure that your child always wears and ANSI, ASTM,
SNELL approved helmet when riding.
Safety Checklist
Before you ride, it is important to carry out the following safety checks:
1. Brakes
Ensure front and rear brakes work properly
Ensure brake shoe pads are not over worn and are correctly position
in relation o the rims.
Ensure brake control cables are lubricated, correctly adjusted and
display no obvious wear.
Ensure brake control levers are lubricated and tightly secured to the
2. Wheel and Tires
Ensure tires are inflated to within the recommended limit as displayed
on the tire sidewall
Ensure tires have tread and have no bulges or excessive wear.
Ensure rims run true and have no obvious wobbles or kinks.
Ensure all wheels spokes are tight and not broken.
Check that axle nuts are tight. If your bicycle is fitted with quick
release axles, make sure locking levers are correctly tensioned and in
the closed position.
3. Steering
Ensure handlebar and stem are correctly adjusted and tightened, and
allow proper steering.
Ensure that the handlebars are set correctly in relation to the forks and
direction of travel.
Check that the headset locking mechanism is properly adjusted and
If the bicycles is fitted with handlebar end extensions, ensure they are
properly position and tightened.
4. Chain
Ensure chain is oiled, clean and runs smoothly.
Extra care is required in wet or dusty conditions.
5. Bearing
Ensure pedals are securely tightened to the cranks.
Check headset, wheel bearings, pedals bearing and bottom bracket
6. Cranks and Pedals
Ensure pedals are securely tightened to the cranks
Ensure cranks are secure to axle and are not bent.
7. Derailleurs
Check that front and rear mechanisms are adjusted and function
Ensure shift and brake levers are attached to the handlebar.
Ensure derailleur, shift levers and shift and brake cables are properly
8. Frame and Fork
Check that the frame and fork are not bent or broken

11. Battery Pack
Ensure the batteries are in good operation condition and kept fully
charged and properly secured and locked.
It is strongly advised that a properly fitting, ANSL or SNELL approved, bicycle safety
helmet be worn at all times when riding your bicycle. In addition, if you are carrying
a passenger on a child safety seat, they must also be wearing a helmet.
The correct helmet should:
-be comfortable
-be lightweight
-have good ventilation
-fit correctly
-cover forehead
Always wear a properly fitted helmet which covers the forehead when riding a
bicycle. Many states require specific safety devices. It is your responsibility to
familiarize yourself with the law of the state where you ride and to comply with all
applicable laws, including properly equipping yourself and your bikes as the law
requires. Reflectors are important safety devices which are designed as an integral
part of your bicycle. Federal regulations require every bicycle to be equipped with
front, rear, wheel, and pedal reflectors. Theses reflectors are designed to pick up and
reflect street lights and car lights in a way that helps you to be seen and recognized
as a moving bicyclist. Check reflectors and their mounting brackets regularly to make
sure they are clean, straight, unbroken and securely mounted, Have your dealer
replace damaged reflectors and straighten or tighten and that are bent or broken.
Component List
Battery Gauge
When the throttle or sensor is engaged (Powering the motor) and the bicycle is in
motion, the LED’s on the battery gauge (on the throttle or separate unit) indicate
instantaneous line voltage as measured at the battery terminals- and not the
available energy in the battery pack.
The line voltage will fluctuate depending on the instantaneous load that the motor is
under. For example ,when starting out from a dead stop, or going up a steep hill, the
motor will be under a high load and may show a reduced number of LED’s.
When the throttle is disengaged (i.e. no power to the motor due to the bicycle being
stationary or coasting) the LED’s on the throttle will indicate the voltage of the
battery pack. The voltage of the battery pack will rise when no load is on the motor.
The best indication of how much battery life is remaining is to check the throttle
LED’s, after reaching cruising speed, on a flat straight road as this will allow the
battery voltage to stabilize and give a much more accurate reading.
LED display
Press once for ON and press and hold for 3 seconds for OFF, and you can adjust the
speed with "-" and "+".
LCD display
Press power on&off and you can adjust the speed with "-" and "+"
And please press the “on/off” button, then the power will be working or cut off.
Throttle, are equipped on some models of electric bicycles. Throttles operate be
rotating the throttle much like a motorcycle. They generally are the inner half of the
right side handlebar grip and may also contain a battery gauge. The more you twist
the throttle, the faster the motor system will propel bicycle.
TAG Throttle
TAG (Twist and Go)
Before you begin riding, turn the main power switch on, then start riding as you
would ride a regular, non-motor assisted bicycle. After you have begun to ride,
slowly twist the throttle (on equipped models) towards you .The more you twist the
throttle, the more motor power will be applied to the wheels. You may feel the
pedals get a “lighter” feel than riding without the motor assisting you. Once you
have twisted the throttle all the way, the motor will accelerate you to its full speed
of about 15mph (24km/h).
PAS (Pedal Activated System)
Electric bicycles with this system have a throttle that is only active when the pedals
are in forward motion. A sensor ring on the bottom bracket spindle rotates and a
sensor reads this rotation.
Begin by first riding as if you are on a normal non-electric bicycle, then while the
pedal are in motion slowly twist the throttle towards you the activate the motor
Taking Care of Your Batteries
Proper maintenance of the batteries will maximize their lifespan and available ride
·We use SLA (Sealed Lead Acid) or Li-Ion (Lithium Ion) batteries in all of our electric
bicycles. These are very user friendly types of batteries when cared for properly.
·Batteries should be fully charged immediately when they are received for the
Below are the recommended charge times for each type of the batteries.
·Li-Ion(Lithium Ion) batteries 4-6 hours
·SLA(Sealed Lead Acid) 6-8 hours
·Charge batteries at least very 90 days for Li-ion and every 30 days for SLA until
normal use is resumed.
·Always store bicycle with fully charged batteries.
·Never charge the batteries for more than 24 hours
·Always disconnect the charger form the wall outlet and bicycle when charging is
complete (as indicated by the status on the charger) before storing the bicycle.
·Do not store the batteries below 50°Fahrenheit and never allow batteries to
freeze (Below 32°Fahrenheit)
·Li Bikes are equipped with a 5 seconds sleep mode .If do not use the battery for a
long time we suggest you to keep the button above the battery for 5 seconds till
the light flash then it will go into “Sleep Mode” and if you want the Li battery
working then do same before.
·Always be sure to turn the bike “OFF” after each use via the ON/OFF power switch.
If you have left the power switch on or your product have not been charged for a
long period of time, the batteries may reach a stage at which it will no longer hold
·Be friendly to the environment! Be sure to recycle your old batteries at a local
battery recycling center. Do not throw them in the garbage.
·Frequent “stops and starts” will drain a battery more quickly than sustained. long
term use.
·Even with proper care, rechargeable batteries do not last forever. Average battery
life depends on use and conditions.
· The Li-Ion battery rear lights power is directly on the rear of battery .
· The Battery power switch is the Red Button under the rear battery (beneath LED
· The Li-Ion battery charger connector is covered by a rubber cover when you lift the
battery handle.
· The SLA Switch for On/Off is the key, rotate clockwise to turn on the battery power.
· SLA charger connector and Fuse on opposite side.
Li battery model
1. Push the battery box into the compartment along the rail, turn the key to lock the
box first then second turn on the power.
2.Turn the key to unlock the battery box by first pushing the key.
The electric bike comes with its own “Smart Charger” that connects with an
easy-access charger port for recharging the batteries. This charger has lights which
show the battery charge status.
Batteries work best when they have a full charge, so always be sure to recharge
them fully after each ride. If you leave then in a run-down condition, without
recharging them, it will shorten their life expectancy.
Li-Ion (Lithium ion ) batteries –charge for 4-6 hours
The charger may get warm to the touch, so make sure you charge they are in an
open area and do not lay anything on the charger unit while charging. Although
you cannot over-charge the batteries using the “Smart Charger”,
We recommend that you do not leave the charger plugged in for more the 24
If your charger shows a solid green light after charging for a short period of time,
your battery may have been only partially discharged (Short ride), or this may be
the sign of a partially worn out battery reduced charge capacity. Continue
charging for the full time, to cover all the bases. If the battery still has not charged,
you may need to replace it.
Even with Proper care, a rechargeable battery dose not last forever. Average
battery life depends of use and conditions.
The charger and charger port should be regularly inspected for damage
(Cord, plug, enclosure, etc.). If damage is found stop using until the damage part
can be repaired or replaced.
How to use the Li-ion battery charger
1. Red light means charging
2. Green light means charge-full
3. Input: AC100-240V~, 1.6A (Max) 50/60Hz
4. Output: 42.00V—2.0A
5. Plug the charger into the outlet and turn the charger “ON” via the switch on the
black side. The red power light on the front of the charger will illuminate when the
charger is working properly.
6. Insert the XLR plug into the charger port on the bike being sure the charger plug is
fully seated in the charger port. The second light will start to flash orange for several
seconds while the charger is “seeking” the battery.
7. Once the charger has “found” the battery the blinking orange light will stop
flashing and turn solid orange and cooling fan will start. At this point the charger
process has begun.
8. Once the battery reaches full charger, the orange light will turn solid green.
9. When charging is complete, unplug the charger from the wall before removing it
from the charger port.
Charge for the full time. If the battery still has not charged, you may need to replace
Use only Drummer International ,LLC Authorized Li-Ion chargers with
bicycles equipped with Li-Ion batteries.
Using any other charger will damage the batteries and void your warranty.
Battery Care
Battery Storage
How to store your battery for a extended time?
Charge the battery every 3 months to avoid capacity loss. Batteries slowly
self-discharge when left unused for a long time; if battery cells are allowed to reach a
critically low voltage, their lifespan and capacity will be permanently reduced.
Always disconnect your charger from the wall outlet and battery before storing the
Avoid storing your battery in extreme temperatures, whether hot or cold.
Batteries are best kept in a cool, dry place. Do not allow batteries to accumulate
condensation, as this could cause shorting and corrosion.
The recommended storage temperature for both SLA and Li-ion batteries is between
Avoid exposing the battery to extreme heat (104。F or higher) for long time.
Battery FAQ’
Q; Do I need to charge the batteries before using them?
A; Yes, You should charge the batteries fully before first using them.
Q: Do I need to “break-in” my batteries?
A: Yes, the batteries will need to have a “break-in” cycle consisting of-three
discharge/charge cycles before then will reach optimum performance. This involves
three complete discharges and three complete recharges. After this initial “break-in”
cycle batteries will have maximum possible performance and less line voltage
fluctuations under load.
Q: How long will the batteries hold their charge?
A: All batteries will self-discharge when not in use. The self-discharge rate depends
on the temperature at which they are stored. Excessively cold or hot storage
temperature will drain the batteries faster than normal. Ideally the batteries should
be stored at room temperature.
Q: Why should I recharge my batteries at least 90 days (Li-ion) and every 30 days
(SLA) when I am not using them?
A: Batteries naturally loose their charge over time. To keep batteries in optimal
condition and extend their life, it is recommended that a top-off recharge be
performed at least every 90 days for Li-ion batteries and at 30 days for SLA batteries.
Q: Will I get more performance for my bike if I leave the batteries to charge longer?
A: No, once the batteries are fully charged ( as indicated by the light on the charger)
it is best to unplug them from the charger, leaving the batteries charging longer than
necessary is called “overcharging” and will not increase performance. Our bikes
supplied chargers are designed to avoid over-charging a battery. Still we
recommended that you always unplug a charger after the units is fully charged to
avoid the possibility of unanticipated circumstances such as an unexpected power
surge from a lighting strike(or other power line anomaly) potentially causing damage.
Only use DRUMMER INTERNATIONAL ,LLC supply chargers.
Q; Is it normal that the batteries get warm when recharging?
A: Yes, it is normal that the batteries will become warm to the touch during the
recharging process. This is because the increase of internal resistance and less
energy conversion efficiency from electric energy to chemical energy.
Q; How long will my batteries last before needing replacement?
A; Average battery life depends on use and conditions. Even with proper care,
recharge batteries does not last forever.
Please recycle your old batteries
 The SLA battery pack is included 2x12V sealed lead acid batteries. They must be
recycled or disposed of in an environmentally safe and legal manner.
 The batteries used in the SLA battery packs are chemically identical to common
automotive starter batteries and can be returned to any site that accepts
automotive lead acid batteries for recycling. Examples include automotive
service stores, automotive service center, battery recyclers, etc. To find a
battery recycling facility in your area please visit either of these websites:
 When recycling lead batteries do not mix them with non-lead batteries.
Non-lead batteries pose a fire/explosion hazard if brought to a lead battery
recycling facility. Lead batteries (example: sealed lead acid batteries, etc.) and
non-lead batteries (example: lithium ion, nickel metal hydride, etc.) are recycled
at different facilities.
 Do not dispose of batteries in a fire due to risk of explosion.
 In the event of disposal, dispose only in accordance with federal, state and local
Seat Adjustment
1.Use the 13mm wrench to adjust the angle of the seat which is comfortable for you.
(SLA or Li-ion battery same)
2. Use the quick release to adjust the height of the seat post.
You can lift the seat and take out of the battery to recharge separately.
Braking Adjustment
1. If fitted with V-brakes, insert the brake body into the center spring hole in the
frame mounting boss, and then secure the brake body to the frame with the link
fixing bolt.
2. While holding the shoe against the rim, adjust the amount of shoe protrusion by
interchanging the position of the B washers (i.e 6mm and 3mm) so that dimension A
is kept at 39mm or more.
3. While holding the shoe against the rim, tighten the shoe fixing nut.
4. Pass the inner cable through the inner cable lead. Set the cable with a clearance of
1mm between each brake pad and the rim, tighten the cable fixing bolt.
5. Adjust the balance with the spring tension adjustment screws
6. Depress the brake lever about 10 times as far as the grip to check that everything
is operating correctly and that the shoe clearance is corrected before riding the bike.
Chain Adjustment
The chain must be kept clean, rust free and frequently lubricated in order to extend
its life as long as possible. It require replacement if it stretches, breaks,or causes
inefficient gear shifting. Make sure that there are no stiff links, they must all move
The chain should be lubricated with light oil at least every month, or more often in
wet, muddy, or dusty conditions. Take care to wipe off excess oil, and not to get oil
on the tires or rim braking surfaces
Adjustment and Replacement
On derailleur geared bicycles the rear derailleur automatically tensions the chain. To
adjust the chain on single speed freewheel, coaster hub braked or 3 speed hub
geared bicycles:
1. Loosen the rear axle nuts ( and coaster brake arm clip ) and move the wheel
forward to loosen , or backward to tighten, in the frame.
2. When correctly adjusted, the chain should have approximately 10mm(3/8’’) of
vertical movement when checked in the center between the chain wheel and
rear sprocket. Center the wheel in the frame and re-tighten the axle nuts after
any adjustment. Bicycles which have a single speed freewheel, coaster brake or
3- speed hub, generally use a wider type chain than derailleur geared bicycles.
These chains can be disconnected by way of a special U-shaped joining link, that
can be pried off of the master link with a screwdriver. To replace, feed the chain
around the chain wheel and rear sprocket, fit the master link into the rollers
into each end of the chain, position the master link side plate, and slip on the
U-shaped snap-on plate. Make sure the open end of the U-shaped plate is
trailing as the link approaches the chain wheel when pedaling forward.
Derailleur geared bicycle use narrower chains and require a special tool to fit and
remove chain links, or to change the length. To remove, fit the rivet tool so that
punch pin is centered over any one of the chain rivets. Push the rivet almost all the
way out, then back out the punch and remove the tool. Holding the chain on both
sides of the punched rivet, bend it slightly to release link form the rivet. To install,
feed chain around chain wheel, rear sprocket and derailleur cage with rivet facing
away from the bicycle. Bring the two ends together within the special tool and
punch the rivet into place. Be sure not to push rivet too for through side plate.
All Drummer International ,LLC electric bicycles are equipped with fuse. The fuse
may be located, depending on the model of the bike, in the following locations:
In the event of an overload the fuse will pop and need to be replaced. In this
instance replace only approved part from Drummer International ,LLC.
Risk of fire. Do not bypass fuse.
