Important Notice
Congratulations and thank you for purchasing SURRON STORM BEE electric motorcycle. We
sincerely welcome you to the community of SURRON electric motorcycle riders.
This manual is designed to provide you with a better understanding of the operation,
maintenance requirements and troubleshooting of your electric motorcycle. Please take your
time to read this manual carefully as well as all safety labels before riding. Please DO NOT use it
until you understand the basic operation and features of the STORM BEE electric motorcycle.
You can also find this manual to download on our official website http://www.sur-ron.com. If
there is any critical update, it will be released on the official website. Please visit our official
website to get the latest version.
Please ensure that this manual stays with the motorcycle at all times, even when you resell it.
If you have any questions regarding the operation or maintenance of your motorcycle, please
contact the after-sales service department of Sur-ron at:
ser[email protected]
Warning: If the power supply is damaged or the charging system malfunctioned, please contact
your authorized dealer designated by the manufacturer immediately for replacement or repair.
About This Manual
This Manual covers the following motorcycles:
STORM BEE R(road): All terrain version
ABS (optional)
Headlight and Indicators
All terrain tires (19-inch diameter front and 17-inch diameter rear)
STORM BEE E (enduro): Trail version
ABS (optional)

Headlight and Indicators
Off-road tire (21-inch diameter front and 18-inch diameter rear)
STORM BEE F (Off road): Off-road version
Off-road tire (21-inch diameter front and 18-inch diameter rear)
Riding tips for maximum range
Range varies in STORM BEE electric motorcycles similarly to how it varies in gas motorcycles.
The range variety of STORM BEE electric motorcycles comes from the riding application after
each full charge. In addition to riding habits, energy consumption is also affected by
environmental conditions (such as extreme cold or hot weather, riding on steep soft road, etc.).
To achieve the maximum range with a single charge, please pay attention to reduce the
maximum speed, less sudden acceleration and maintain a constant speed to ensure the
maximum range.
To reach the maximum range, please following the tips below:
• Avoid frequent and acute acceleration and braking.
• under safe riding conditions, please reduce the riding speed by using the throttle to decelerate
instead of pulling the brake lever.When your riding the STORM BEE, as long as the motorcycle is
moving and the throttle is in the idle position, the energy regenerative brake will reduce the speed of
the STORM BEE and converting the kinetic energy to charge the battery pack.
• Maintain a correct tire pressure (Please refer to Recommended tire pressure table page10.9.)
• Remove unnecessary goods and reduce load.
• The maximum range in winter or summer could be slightly different.
In conclusion, you can estimate your range according to the above factors and your riding habits.
Note: The range will be reduced according to the various tough road conditions during off-road
riding.
1.10
Transporting
It is highly recommended that the electric motorcycle be firmly secured on the transport frame
using ratchet straps while it is being transported. It is recommended that the soft straps must
be used to reduces scratches or other damages.
It is recommended to fix the ratchet straps according to the points shown in the figure. The
front two are tied to the handlebar and the back two are tied to the left and right swing arm.
Please do not damage the chain or brake line when tied the strap.The tie down straps should
be at a 45° angle from the motorcycle. Follow the manufactures instructions for the ratchet
straps you are using.

2.1
Safety Riding Requirement
Your electric motorcycle can provide many years of service and pleasure if you take
responsibility for your own safety and understand the challenges you can meet while riding.
There is a lot you can do to protect yourself whilst riding. You will find many helpful
recommendations throughout this manual. The following are a few that we consider to be most
important.
• STORM BEE is a high performance electric motorcycle and should be treated with extreme
caution.
• Proper safety gear, including a regionally/nationally approved helmet, riding boots, eyewear,
gloves, and protective clothing should be worn while riding to reduce the risk of potential
injury. We highly recommend the use of full height motocross boots since the vast majority of
motorcycle injuries are through leg and foot impact.
• Read all warnings and instructions in this manual as well as all the safety labels before
operating your electric motorcycle.
• Never allow a guest to ride your electric motorcycle without proper instruction.
• Ensure you have the legal qualification to ride the motorcycle before operation.
• Never consume alcohol or drugs before operation of your electric motorcycle.
• Persons unwilling or unable to take responsibility for their actions should not use this
motorcycle. You assume all responsibility while operating your motorcycle. The seller assumes
no liability for misuse or operator negligence.
• Prior to each use, the rider must check everything in the “check before ride”section on page
7.1, and the charge level of the battery pack as indicated on the dashboard display charge
indicator.
• It is important to keep your motorcycle properly maintained and in safe riding condition.
Having a breakdown can be difficult, especially if you are stranded off-road far from your base.
To help avoid problems, inspect your motorcycle before every ride and perform all
recommended maintenance according to the maintenance schedule and adjustment

requirements listed in this manual. Be sure you understand the importance of checking all items
thoroughly before riding. If you are the STORM BEE off-road version owner, please understand
your motorcycle is designed and manufactured for off-road use only. The tires are not made for
paved surface use and the motorcycle does not have Turn indicators or other features required
for use on public roads. If you need to cross a paved or public road, get off and walk your
motorcycle across.
• Modifications to the motorcycle may render the motorcycle unsafe and may cause severe
personal injury. The manufacturer cannot be held liable for non-approved modifications.
• Be very careful when loading or adding accessories to your motorcycle. Large, bulky, or heavy
items may adversely affect the handling and performance of your motorcycle.
2.2
Important Information
Several important operation considerations are listed below:
• Always turn the key switch(A) and motor stop switch(B) to the OFF position when not actively
riding. It is extremely easy to forget that the motorcycle is still in standby mode because it is
completely silent. An accident can occur if the motorcycle is left powered up while getting on or
off the motorcycle.
• Turn the motor stop switch (B) OFF when pushing or moving the motorcycle.
• Use the parking brake (C) when you are stopped on a ramp or steep hill. Do not hold partial
throttle to keep the motorcycle stationary on a ramp or steep hill, it can trigger the locked rotor
protection which cause the motorcycle to slip back.

• Please recharge the battery pack of your electric motorcycle after each use. Once fully
charged, disconnect from AC power supply. Make sure that the charging is carried out in an
open space or with monitoring.
• While unplugged with the key in the OFF position, the motorcycles electronic components will
consume a small amount of power and the battery pack will drain extremely slowly. If you
don’t ride for an extended period of time (30 days or more), you may need to charge the
electric motorcycle for a few hours prior to your next ride. The battery pack will be damaged if
it is stored for a long time under low power.
CAUTION: Only charge the STORM BEE battery pack with the motorcycle’s original charger or
the manufacture approved accessory charger.
• The battery pack does not require nor benefit from deep discharging. To get the most battery
pack life, recharge the battery pack after each ride. Constantly leaving a battery pack in a deep
discharging state will cause battery cell damage.
•Failure to follow battery pack storage and charging instructions as described in this Manual
may void the warranty of your STORM BEE electric Motorcycle. These guidelines have been
rigorously tested to ensure maximum battery pack efficiency and service.
