Eunorau Defender-S Electric Bike
Eunorau Defender-S Electric Bike
"Moooooore power!"
The first thing you’ll notice about this e-bike is the power and torque.
From the moment you blip the throttle, it just rockets forward. The combination of fat tires and full suspension mean that you’re riding on the bicycle equivalent of a memory foam mattress, especially when you drop the tire pressure. The ride is pretty darn cushy.
Dual Suspension/Dual Motor/Dual Battery
With 1500 watts of power, the EUNORAU DEFENDER S was designed to defeat all kinds of terrain and weather conditions, even being able to carry additional weight. This electric bike model is especially popular for the hunting enthusiasts; having the strength to pull or carry the game back to your vehicle.
Rear Suspension
The EXA rear suspension sets the Eunorau DEFENDER-S apart from the rest of our lineup, making it the ultimate eBike. Take on any trail with maximum comfort and control.
RST Suspension Fork
Absorbing a lot of jarring bumps and shocks on rugged routes, the RST fork helps maintain your energy, helping you focus on riding better and faster.

Product FAQs
Eunorau Product FAQs
1. Does EUNORAU use a throttle on its e-bikes?
A thumb throttle can be fitted to most of the eBikes in our range.The throttle on the e-bike can be activated from a complete stop.
2. What's the difference between Class 1, 2 and 3 e-bikes?
New legislation became effective in January 2016. The current regulations define an “electric bicycle” as: a bicycle equipped with fully operable pedals and an electric motor of less than 750 watts, separated into three classes:
1. A "class 1 electric bicycle,” or “low-speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the bicycle reaches the speed of 20 miles per hour.
2. A "class 2 electric bicycle,” or “low-speed throttle-assisted electric bicycle,” is a bicycle equipped with a motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour.
3. A "class 3 electric bicycle,” or “speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, (no throttle) and that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour and equipped with a speedometer.
3. Why does the battery indicator shown 84% for BBSHD motors?
Lots of customers used a 52V battery to connect with a 48V30A controller.Then the display might shown high voltage error 07. So BAFANG has update the 48V30A controller to 52V28A, then it can compatible with both 48V and 52V batteries. For a 52V battery it will show 100% on the display when connecting to the 52V controller, but for 48V battery,it will show 84%. We're still trying to resolve this matter,it's not a big question, it won't effect any functions.
SOLUTION:
Step1. Buy a program cable from us, here's the link: https://eunorau-ebike.com/collections/bbs-ena-kit-parts/products/8fun-bafang-center-motor-middle-drive-motor-kit-bafang-usb-programmed-cable
Step3.Follow the instruction complete program as written
4. Can I charge the bike without the battery?
Yes! You can access the charge port and the USB port on all EUNORAU bike models without removing the the battery from the bike.Also your battery can be brought inside and set to charge.
5. How long does the battery last?
Batteries typically last 5-6 years. However, this can vary depending on how much you use your e-bike. EUNORAU batteries will still deliver more than 80% of their original capacity after 500 charge cycles.
To prolong the lifetime of the battery there are several procedures that can be followed. The main ones include:
1.If storing the battery for more than 2 weeks it should be kept in a cool, dry place with a 70%-80% charge remaining in it.
2.Avoid running the battery completely flat. Charging batteries when they still have 10-15% of power remaining will significantly extend their lifetime.
6. How long does it take to charge an EUNORAU Lithium Ion Battery?
Depending on the battery and charger type a full battery charge will take between 3-8 hours
7. Does the battery charge when pedaling and/or braking?
The technology for charging batteries through pedaling hasn't reached an efficiency level we consider satisfactory yet, but we're always looking to innovate on our models.Currently only MAX-CARGO and JUMBO apply this function.
Regenerative braking is great in a car or motorbike with higher inertia but a bike isn’t heavy enough to allow the breaks to generate enough energy to significantly charge the battery.
8. Do EUNORAU batteries have an internal battery management system (BMS)?
All EUNORAU batteries have an internal BMS. The BMS regulates the current and voltage entering and exiting the battery. It prolongs the lifetime of the battery and ensures all the cells are drained at equal rates. It also protects the battery from transient events and monitors the temperature of the cells.
9. What temperatures can EUNORAU Bike handle?
The battery is the major component on the bike that may need extra care in extreme weather. The optimal operating temperature for the EUNORAU batteries is 10℃ to 55℃.
10. Can the bike get wet?
Yes! We take our bikes through mountain streams and rain almost every day. The motor and electronic components are sealed and built to take a beating.
11. Are the bikes waterproof?
EUNORAU bikes are water resistant which means they are able to resist the penetration of water to some degree but not entirely. Riding in the rain and washing your bike won't cause any damage but the electronic components are not recommended to be exposed to water for long periods of time.
Note: The battery can only get wet while it's inserted into the battery housing.
12. Can extreme temperature damage EUNORAU bikes?
The only component that you need to be concerned about when operating in extreme temperatures is the battery. The optimal operating temperature for a EUNORAU battery is 10℃ to 55℃. Battery efficiency can be severely limited outside of these temperatures and should be avoided as much as possible.

If an order is placed on a product that is listed as back-ordered (or is advised), our protocol is to charge the customer's credit card or PayPal account. In order to have more control over this unfortunate fulfillment delay, we must process your payment when your order is placed to prevent:
Undesired delays in receipt of your product by you until proper information can be provided by you to us because of unintentional change of payment information.
Intentional attempts at fraudulent receipt of products by way of purposely providing false payment information.
Collecting and handling of your sensitive financial information through a delayed date of order fulfillment and shipment. Our strict internal controls are in place to limit impressions or realities of fraud, and we make every effort to not, at any point, be in possession of your sensitive financial information.
Therefore we do this to avoid costly and frustrating postponements, cancellations, rerouting, and in some cases unfortunate fraudulent receipt of shipments. This usually happens due to intentional or unintentionally submitted false payment information. Therefore, this back-order protocol has been put in place to limit unnecessary and excessive costs of doing business, which allows us to keep our prices lower for you, our customer. Thank you for your patience and understanding with any back-order you may place with us.
While Waiting...
If you placed a back-order and you did not intend to do so, you may do the following:
Review other comparable products on our site for purchase in place of your current order. If you would like to modify your order, please place a new order and contact us immediately after so we can refund your original order.
If your order has not already shipped, we can cancel and refund your order in full after a brief period of confirming the order cancellation with the manufacturer. You can e-mail us at info@vortexcycles.bike with your cancellation request. You may also request inventory availability so a new order can be placed when the item becomes available.
Please wait a minimum of four (4) business days for your credit card company to post the credit.
Please note, that unless we are advised by you in a written email reply indicating either of the above two options prior to shipment, we will assume that you want to keep your present order in place until the product is available to ship (requiring no post-order response from you). We will continue to diligently work on your behalf with the manufacturer to fulfill your order as soon as possible and advise on freight and tracking information when it is made available to us.
Lastly, all ETA's are subject to change. VortexCycles does not and cannot control any timeline regarding orders due to us solely being an Authorized Dealer of each of the brands we sell, not the brand/manufacturer of the products ourselves.
