Who the R1+ is for
Buy it if
- Off-road and private land — this is a dirt bike, not a road-legal e-bike
Look elsewhere if
- Commuting or bike paths: this is not street-legal as an e-bike in most US states
- Anyone who needs to lift the bike regularly — it weighs 150lbs / 68kg
The motor
Eunorau specifies 72V5,000W Advanced LPMSM Mid-Motor with Peak Power 17,000W. A mid-drive delivers its torque through the gears, which is why it holds a steep climb where a hub motor stalls.
Battery and range
Battery: 72V40Ah Samsung 50S 21700 Cell Lithium-ion Removable Battery Max. Eunorau rates the range at 75MI/120KM (under 16MPH/25KMH). Charging takes 4 hours. Real-world range moves with rider weight, terrain, temperature and throttle use.
Suspension
Front: 200mm/High and Low-Speed Compression Damping with 200mm Travel. Rear: 85mm Travel.
Brakes and tires
Brakes: 4 pistons 203mm Hydraulic Disc Brake, FR 220mm+RR 203mm.
Size, fit and capacity
The bike weighs 150lbs / 68kg.
The honest ledger
Green flags
- Mid-drive motor — it puts power through the gears, which is what lets it climb steep, loose ground where a hub motor bogs down
- Genuine suspension at both ends — 200mm/High and Low-Speed Compression Damping with 200mm Travel up front, 85mm Travel at the rear
- Hydraulic disc brakes
Red flags
- Eunorau publishes no UL certification for this model. If your building or insurer requires a UL-listed battery, ask us before ordering rather than assuming
- 150lbs / 68kg is heavy — fine on the road, awkward on stairs or a car rack
- Eunorau publishes no payload capacity for this model — email us and we will ask them rather than guess

What it covers
Manufacturing defects in Eunorau's original parts and components.
Eunorau states it continues to support the product after the warranty period as a manufacturer courtesy, and may ask only for shipping costs on replacement parts.
What you must do
- You are the original purchaser — the warranty does not transfer
- Proof of purchase (your Redtail order confirmation)
- Product registration with Eunorau right after purchase
- An e-bike check-up by a Eunorau specialist or dealer after the first year of use
Not covered
- Ordinary wear and tear — brake pads, rotors, spokes, grips, shifters, brake cables and casings, tires and tubes, chains, chainrings, cassettes, transmission gears
- Labor charges for part replacement
- Corrosion from moisture or heat, and cosmetic deterioration of the finish
- Damage from accident, abuse, stunt riding, racing, improper storage, or neglect
24-Month+ Limited Warranty issued by Eunorau Bikes, a Nevada corporation. Bikes bought for commercial use — rental fleets, delivery, sharing programs — get a 50% reduced warranty period. Full terms are published by Eunorau at eunorau-ebike.com/pages/warranty. Redtail coordinates warranty claims for bikes bought from us, so send it to us rather than to Eunorau: support@redtailebikes.com.
Manuals & documentation
In the box
Eunorau's spec sheet for this model lists a printed manual and a tool kit as included.
Any other document
Eunorau publishes display, controller, shock and accessory manuals across several files. Tell us which one you need and we will send you our copy, so you are not hunting through a supplier download hub.
Eunorau publishes display and component manuals rather than a per-bike user manual. We link only the manual Eunorau lists against this exact model. Need a document we haven't linked? Email support@redtailebikes.com and we'll request it from Eunorau.
Shipping, returns & support
Shipping
Free shipping on every electric bike within the contiguous United States (lower 48).
Orders are prepared and dispatched within 1–3 business days. Most e-bikes arrive within 5–10 business days after dispatch.
Ships via UPS, FedEx, or LTL freight for larger items, with tracking emailed at dispatch. Freight deliveries may need a scheduled appointment and a signature.
On delivery
Inspect your shipment at delivery. Damage, defects, or incorrect items must be reported with photos within 48 hours.
If a bike arrives dead, won't charge, throws an error code, or has a faulty component, it is covered under the manufacturer warranty and Redtail coordinates repair or replacement remotely.
Returns
Change-of-mind returns accepted only on unopened, factory-sealed items requested within 72 hours of delivery, with a 15% restocking fee plus return shipping. Once a box is opened or a bike is ridden, it is no longer eligible.
Order cancellations carry a 3% transaction fee, because card-processing fees are non-recoverable.
Alaska, Hawaii, U.S. territories, P.O. boxes, and remote areas may incur extra charges or be excluded — contact us before ordering. Full terms: Shipping Policy · Refund & Return Policy.
Frequently asked questions
How far does the Eunorau R1+ go on one charge?
Eunorau rates the R1+ at 75MI/120KM (under 16MPH/25KMH). Charging takes 4 hours. Manufacturer range figures are measured under favorable conditions — expect less with hills, heavy loads, cold weather or heavy throttle use.
How fast is the Eunorau R1+?
Eunorau publishes 59MPH / 95KMH. E-bike class rules and speed limits are set by state and local law in the U.S., so check the rules where you ride before you buy.
Why choose a mid-drive over a hub motor?
A mid-drive delivers power through the bike's gears, so it multiplies torque on a climb the same way your legs do in a low gear. A hub motor delivers a fixed output at the wheel and bogs down on steep, loose ground.
What warranty covers the Eunorau R1+?
Eunorau's 24-Month+ Limited Warranty: 10 years on the frame and 24 months on the battery, motor and electrical components, covering manufacturing defects. It requires registration with Eunorau after purchase, applies to the original purchaser only, and excludes wear items and labor. Redtail coordinates claims for bikes bought from us.
How does the R1+ ship, and can I return it?
Free shipping within the contiguous U.S., dispatched in 1–3 business days and typically delivered 5–10 business days later. Inspect it at delivery — damage or defects must be reported with photos within 48 hours. Unopened change-of-mind returns are accepted within 72 hours with a 15% restocking fee plus return shipping.
