Eunorau Flash Electric Bike
Eunorau Flash Electric Bike: Multi-Battery Long-Range Power
The Eunorau Flash is a long-range electric bike designed for riders who want to cover serious distance with confidence. With a triple-battery configuration and a choice of high-torque drive systems, the Flash powers you farther and with more stability than most bikes in its class.
Triple-Battery Architecture for Extended Rides
The standard 52V 16Ah battery is already capable, but you can expand to a top-tube 52V 21Ah and a down-tube 52V 17Ah for maximum range. Range varies based on rider weight, terrain, assist level, weather conditions, and battery configuration. This extended capacity lets you plan longer routes with fewer charging stops.
Three Drive Configurations
- Mid-drive: 52V 1000W with 220 Nm of torque for precise control and powerful hill climbing with a stable center of gravity.
- All-wheel-drive: 52V 1500W (dual 750W motors) with 184 Nm torque for exceptional traction on slick, loose, or steep surfaces.
- Rear-drive: 52V 750W rear motor with 92 Nm torque for a nimble, responsive feel on city streets and narrow lanes.
Ride Comfort
The EXSHO STRONG-DH front suspension fork delivers 80mm of travel with adjustable compression and lockout, absorbing ruts, potholes, and rough surfaces. A 290mm rear spring on the mid-drive layout further smooths out bumps for longer, more comfortable rides.
Built for Real Riders and Loads
Strong aluminum alloy 6061 frame supports a total payload of up to 440 lbs. Adjustable rider height range from 5'2" to 6'4". 20" x 4.0" CST tires and hydraulic disc brakes ensure reliable stopping power on diverse surfaces.

If you place an order for a product listed as Back-Ordered, our protocol is to process your payment at the time the order is placed. This ensures your position in the fulfillment queue and prevents delays that can occur if payment information changes or authorizations expire during the waiting period.
By processing payments upfront, we are able to:
-
Secure Your Inventory: Immediately lock in your order with the manufacturer.
-
Enhance Security: Ensure all transactions are cleared through our secure processors, protecting your sensitive data from being stored for delayed billing.
-
Maintain Competitive Pricing: Reduce administrative costs, allowing us to keep our prices as low as possible for our customers.
While You Wait

-
Switch Your Order: You may browse comparable products on our site. To modify an order, please place a new order for the in-stock item and contact us immediately to refund your original back-order.
-

Refund Timing: Please allow approximately four (4) business days for your financial institution to post the credit to your account.
Important Note on Timelines
Unless we receive written notice of a cancellation or modification via email, we will maintain your active order and continue working diligently with the manufacturer to fulfill it. Please note that all ETAs are subject to change. As an Authorized Dealer, VortexCycles facilitates the order and shipping process, but we do not control the manufacturing or shipping timelines of the brands we represent.
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.
