Eunorau rates it at a 52V1000W mid-drive motor rated at 220 N.m, a 20 mph top speed, a manufacturer range of up to 65 miles (135 miles dual battery | 220 miles triple battery) and a 440 lbs payload. It's listed as Class 3, UL certified, sized for riders 5'2" ~ 6'4", and it weighs 82-92 lbs. $2,499 with free shipping in the lower 48. 1000 W220 N.m motor 16 AhBattery 65 miMfr. range 20 mphMfr. top speed 20×4.0Tires Class, speed & certification E-bike class Class 3 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 20 MPH 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 FLASH 2.0 Mid-Drive Moto is for Buy it if Riders who want a motorcycle stance with e-bike running costs Riders who need a UL-certified battery to charge indoors Look elsewhere if Anyone wanting a light bike they can lift — these are the heavy end of the range Anywhere Class 3 is barred — check your local path and trail rules first Anyone who needs to lift the bike regularly — it weighs 82-92 lbs Buyers who want the headline range without buying the second battery PowerThe motor Eunorau specifies 52V1000W Truckrun Mid Drive Motor with 220N.m Torque. A mid-drive delivers its torque through the gears, which is why it holds a steep climb where a hub motor stalls. RangeBattery and range Battery: 52V16Ah Standard (Optional: Top Tube 52V21Ah / Down Tube 52V17Ah). Eunorau rates the range at Up to 65 Miles (135 Miles Dual Battery | 220 Miles Triple Battery). Real-world range moves with rider weight, terrain, temperature and throttle use. RideSuspension Front: EXSHO STRONG-DH 80mm Travel Fork. Rear: Eunorau 290MM Double Rear Spring Suspension. ControlBrakes and tires Brakes: Hydraulic Disc Brakes. Tires: CST 20" x 4.0". FitSize, fit and capacity Eunorau publishes a total payload capacity of 440 lbs. Recommended rider height is 5'2" ~ 6'4". The bike weighs 82-92 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 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 — EXSHO STRONG-DH 80mm Travel Fork up front, Eunorau 290MM Double Rear Spring Suspension at the rear 440 lbs payload — the highest of any Eunorau we stock Hydraulic disc brakes with motor cut-off in the levers Red flags Class 3 is a restriction as well as a feature — many US bike paths, parks and multi-use trails bar Class 3, so check your local rules before buying 82-92 lbs is heavy — fine on the road, awkward on stairs or a car rack The headline range (Up to 65 Miles (135 Miles Dual Battery | 220 Miles Triple Battery)) assumes the optional second battery, which is bought separately — the standard pack will not reach it Eunorau's own listing is inconsistent here: it badges this model Class 3 but publishes a top speed of 20 MPH. Class 3 normally means 28 mph assisted in the U.S. We've asked Eunorau to resolve it and quote both rather than pick the flattering one How the FLASH 2.0 Mid-Drive Moto compares All figures below are Eunorau's own published numbers.

Warranty Component Coverage Frame 10 years Battery 24 months Motor 24 months Electrical components 24 months 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.

Redtail coordinates warranty claims for bikes bought from us, so send it to us rather than to Eunorau: [email protected]. 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. [email protected] 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 [email protected] 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.

Frequently asked questions How far does the Eunorau FLASH 2.0 Mid-Drive Moto go on one charge?Eunorau rates the FLASH 2.0 Mid-Drive Moto at Up to 65 Miles (135 Miles Dual Battery | 220 Miles Triple Battery). That figure assumes the optional second battery, bought separately. 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 FLASH 2.0 Mid-Drive Moto?Eunorau publishes 20 MPH. It is listed as Class 3. 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. Who does the FLASH 2.0 Mid-Drive Moto fit, and how much can it carry?Eunorau publishes a total payload capacity of 440 lbs. Recommended rider height is 5'2" ~ 6'4". The bike itself weighs 82-92 lbs. Is the Eunorau FLASH 2.0 Mid-Drive Moto UL certified?Yes — Eunorau lists this model as UL certified. In the U.S. that increasingly determines whether you can store and charge the bike inside an apartment building, and some insurers ask for it too. 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 FLASH 2.0 Mid-Drive Moto?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 FLASH 2.0 Mid-Drive Moto 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.
