Who the S1 is for
Buy it if
- Riders 4'9" – 5'10" / 145–180 cm — Eunorau's published fit range for this frame
- Parents who want a power switch Eunorau says carries "lock features to prevent accidental activation"
- Off-road and private land — this is a dirt bike, not a road-legal e-bike
Or one of these instead
- Adult riders — this is built and sized for children
- 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 152lbs / 69 kg
The motor
Eunorau specifies 60V 4,800W Peak Power Middle Motor.
Battery and range
Battery: 60V 30Ah. Eunorau rates the range at 24.8 miles / 40 km. Charging takes 7 hours. Real-world range moves with rider weight, terrain, temperature and throttle use.
Suspension
Front: Inverted aluminum alloy suspension fork for smoother, more controlled riding on uneven terrain. Rear: Adjustable aluminum alloy air shock.
Brakes and tires
Brakes: Hydraulic disc brakes. Tires: 60/100-14 (Front), 80/100-12 (Rear), Black.
Size, fit and capacity
Recommended rider height is 4'9" – 5'10" / 145–180 cm. The bike weighs 152lbs / 69 kg.
The honest ledger
Green flags
- Genuine suspension at both ends — Inverted aluminum alloy suspension fork for smoother, more controlled riding on uneven terrain up front, Adjustable aluminum alloy air shock at the rear
- Hydraulic disc brakes
- Display: 4.58" display, easy-to-read ride information
- Eunorau's own specification answers "UL CERTIFIED: Yes" for this model
- Eunorau publishes a load capacity of 220 lb for this model
Red flags
- It weighs 152lbs / 69 kg — plan how it will be lifted and carried before it arrives
- Eunorau sizes the S1 for riders 4'9" to 5'10" and rates it for 220 lb — a rider taller than 5'10" should read the R1, which Eunorau sizes from 5'2" to 6'4"

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.
