Class, speed & certification
E-bike class
Class 2 Speed limited Unlockable
Class rules are set by state and local law in the U.S. Check the rules where you ride — some paths and trails restrict Class 3.
Top speed
20MPH
UL certified
Yes — as published by Eunorau. UL listing for the battery and electrical system is what many U.S. cities, insurers, and apartment buildings now ask for.
Who the FAT-AWD 2.0 All-Wheel-Drive Fat is for
Buy it if
- Loose, steep, or broken ground — sand, gravel, snow, and root-covered trail
- Riders who need a UL-certified battery to charge indoors
Look elsewhere if
- Anyone who needs to lift the bike regularly — it weighs Step-over 81.5 lbs, step-thru 79.4 lbs
- Buyers who want the headline range without buying the second battery
The motor
Eunorau specifies Front 48V/500W+Rear 500W Hub motor, MAX 110 N.m.
Battery and range
Battery: 48V 15Ah (Optional Second Battery 15Ah). Eunorau rates the range at Up to 80 Miles (with dual batteries). Charging takes 5 - 7 hours. Real-world range moves with rider weight, terrain, temperature and throttle use.
Suspension
Front: RST GUIDE 95mm travel suspension.
Brakes and tires
Brakes: 180mm hydraulic disc brakes. Tires: KENDA Krusade Sport 26" × 4.0 tires.
Size, fit and capacity
Eunorau publishes a total payload capacity of 375 lbs. Recommended rider height is 5'3" ~ 6'1". The bike weighs Step-over 81.5 lbs, step-thru 79.4 lbs.
The honest ledger
Green flags
- UL certified, per Eunorau — increasingly what US cities, insurers and apartment buildings require before an e-bike can be charged indoors
- Class 2, the least-restricted category on most US bike paths — Eunorau notes the limit is unlockable
- Torque sensor rather than a cadence sensor, so assist scales with how hard you actually pedal instead of switching on a beat late
- Front suspension: RST GUIDE 95mm travel suspension
- Hydraulic disc brakes with motor cut-off in the levers
Red flags
- Step-over 81.5 lbs, step-thru 79.4 lbs is heavy — fine on the road, awkward on stairs or a car rack
- The headline range (Up to 80 Miles (with dual batteries)) assumes the optional second battery, which is bought separately — the standard pack will not reach it
- The 7-speed drivetrain (SHIMANO ASLM3157RC 7 Speed) is entry-level — adequate, not a highlight

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.
