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.

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 ONE-TRIKE 2.0 Rear-Drive is for

Buy it if

  • Riders who want stability at a standstill and no balancing at low speed
  • Anyone carrying loads that would unbalance a two-wheeler
  • Riders who need a UL-certified battery to charge indoors

Look elsewhere if

  • Tight bike lanes and narrow doorways — a trike needs real width
  • Anyone who needs to lift the bike regularly — it weighs 85.98 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
  • Front suspension: Eunorau suspension fork, 40 mm travel
  • 440 lbs payload — the highest of any Eunorau we stock

Red flags

  • 85.98 lbs is heavy — fine on the road, awkward on stairs or a car rack
  • Eunorau publishes no maximum speed for this model, so we do not state one and you should not infer a US class from its wattage

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.

support@redtailebikes.com

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.
