Qlife's own photograph of its Spark in Red in a studio scene we generated, under the headline Who is behind Qlife. All 19 listings., with $529 to $1,399 · 18 to 42+ mph · one-year warranty and a badge: 9 bikes we sell beside them, from under $600

Qlife, read in full: its US store, its 23 owner's manuals, its policies and blog, the federal trademark and safety registers, TÜV Rheinland's certificates and the state statutes, read on October 23 and 24, 2026. Who is behind the brand, all 19 listings, where each stands under the law, and nine bikes we sell beside them. Pictured: Qlife's own studio photograph of the Spark in Red, cut from its white background into a studio scene we generated.

Quick Answer — Qlife ebikes are fat-tire, moped-style, folding and three-wheel e-bikes sold from qlifebike.com, a store whose own record lists Sheung Wan, Hong Kong. On October 23, 2026, it listed 19 machines from $529 to $1,399, and 11 of those pages print a top speed above 28 mph, the highest speed any of the three e-bike classes covers.

No CPSC recall, product safety warning or news release named Qlife or a Qlife model when all three registers were read on October 23, 2026 (CPSC recalls), and TÜV Rheinland's public register lists certificates naming the models of 18 of the 19 listings: UL 2849 for 17, and UL 2272 for the Vela E8.

Before you buy one for the road, read where a Qlife stands under the law: at the speeds Qlife prints, every two-wheel Qlife sits outside the e-bike definition in 49 of the 51 US jurisdictions.

If you are shopping, nine bikes we sell stand beside the Qlife models on a rated motor of 350 to 750 W and a top speed their makers' specifications put at 28 mph or less, from under $600, and every e-bike we sell ships free to the lower 48.

What decides a Qlife Price is rarely the hard part: Qlife's single bikes run $529 to $1,399. The deciding questions are speed and law (16 of the 19 Qlife pages print 28 to 42+ mph), which listing you buy, and who will ride it: Qlife describes two Spark trims as built for "young riders". Our e-bike brands list sets Qlife beside the other brands selling e-bikes in the US.

How we verified this profile. Written by Milad Ghobadibeygvand, BScN (Western University, 2014).

Qlife's US store was read in full on October 23, 2026: its store record, all 122 product pages with their records, the 19 bike pages among them, 36 catalog pages, 19 store pages, five policy pages, its blog and all 80 articles on it, saved and searched, and all 23 owner's manuals it links.

Of the 264 store addresses requested, 263 were retrieved in full and one, a legal-notice page, answered "not found". 21 of the 23 manuals carry under 200 characters of text a page, so their text was machine-read from the page images, and every manual page quoted here was checked against its image.

The U.S. Patent and Trademark Office's record for QLIFE, TÜV Rheinland's certificate register and all three CPSC registers were read on October 23, the statutes and the nine cards' prices, stock and specifications at their makers on October 24. Watt-hours are computed from Qlife's own voltage and amp-hour figures.

The speed-and-class screen runs Qlife's printed figures through each jurisdiction's e-bike definition in our state-by-state rule table, and every count on the page comes from a saved file that can be re-run.

Redtail eBikes does not sell Qlife. We do sell the nine alternatives named here. Corrections go to support@redtailebikes.com.

Who is behind Qlife, and where is it based?

Shoppers meet Qlife on its own store and search for it on Amazon and Walmart, and the questions follow: who stands behind it, and is the bike what the listing says? The records answer more of your questions than the store does. Qlife's privacy policy names a Hong Kong company, the federal trademark register names a company in Tianjin, and TÜV Rheinland's certificate register names the Hong Kong company and a second Tianjin company as certificate holders.

Who is behind Qlife, in one line The store names HONG KONG HONGDA NEW ENERGY CO., LIMITED as its privacy contact; the QLIFE bicycle trademark belongs to Tianjin Weizhixing Technology Co., Ltd; and TÜV Rheinland's register lists the Hong Kong company as holder of the e-bike certificates that name Qlife's model families. Each record is quoted below with its link, so you can read it yourself.

The store's own record

Qlife's store record, the public file every Shopify store publishes about itself, gives the store's name as "Qlife Bike", its city as Sheung Wan on Hong Kong Island, its currency as the US dollar, and the United States among the countries it ships to. Its terms of service say the site "is operated by qlifebike.comteam", and name no company.

One page does. The contact paragraph of Qlife's privacy policy gives a phone number, (540) 405-2271, the address sns@qlifebike.com and "HONG KONG HONGDA NEW ENERGY CO., LIMITED, 137-139 Connaught Road Central, 12TH FLOOR, SAN TOI BUILDING, Sheung Wan, Hong Kong Island Hong Kong SAR". No other page among the 263 retrieved on October 23, 2026 names a company behind the store.

If you need Qlife after a sale, customer service runs through service@qlifebike.com. The contact information page lists +1 (833) 475 1642 and hours of "8AM-5PM PST Monday-Friday", and the warranty page and return policy list +1 716 452 9382 for the same hours.

Who owns the QLIFE name

The U.S. Patent and Trademark Office registered QLIFE for "Bicycles" and other vehicle goods in International Class 12 on May 18, 2021, as Registration No. 6,353,539 (serial 90171772), on a first use in commerce of July 1, 2020 (USPTO, TSDR record for serial 90171772).

The registrant was an individual, Li Tao, of Hanzhong in Shaanxi province. The register records assignments of the mark to Tianjin Qijia Technology Co., Ltd and to Tianjin Weizhixing Technology Co., Ltd, with ownership updates entered on October 18, 2023 and March 4, 2026, and lists Tianjin Weizhixing, of the Tianjin Free Trade Zone, as the owner when the file was read on October 23, 2026.

Tianjin Qijia also took the ACTBEST bicycle mark, in February 2023, and our Actbest profile sets out that record and the other points where the two brands' records meet.

A trademark record says who owns a name. It does not tell you who builds a bike or who runs a store, and none of the 263 store pages retrieved names either Tianjin company.

How Qlife describes itself

Qlife's About page tells its story by model year. It counts the Racer Step Over mountain bike, in 2021, as "Our first creation". The Cityone ST followed in 2022, then the Racer and Racer Plus fat-tire bikes in 2023 and the Spark in 2024, a bike it describes as "Reaching speeds over 28 mph and offering up to 65 miles of range". The Qlife Triker three-wheeler came in 2025.

The product record of the Spark calls it "proudly designed in sunny Florida". Seventeen of the 19 bike pages carry a banner reading "160K+ Riders", beside "TÜV Rheinland Verified" on 13 of them and "Safety Certified" on the other four; the two Vela pages carry neither. These are Qlife's own words and figures, printed here as Qlife's.

Where the bikes ship from, and where they are made

Your Qlife ships from inside the country. Its shipping policy says "All orders ship directly from our U.S.-based warehouses", and its FAQ page says "We have completed 95% of the assembly at the factory", leaving the wheels, handlebars and seat for you.

If you want the country of manufacture, four of the 23 owner's manuals Qlife links print "MADE IN CHINA" in the page footer: the manual for the current Qlife Triker Plus (printed page 28), the original Qlife Triker's and the two Racer Step Over manuals. The other 19 manuals, read on October 23 and 24, 2026, show no country line in their last four pages.

Every bike we sell ships free to the lower 48, and we coordinate warranty repairs with its maker.

The safety record: recalls, warnings and the UL 2849 certificates

If you check for recalls first: no federal safety notice names Qlife. The Consumer Product Safety Commission's three public registers were read in full on October 23, 2026, and none named Qlife, Qlife Bike, any Qlife model or any of the four companies on Qlife's store, trademark and certificate records. On the certification side, TÜV Rheinland's register names the models of 18 of the 19 listings.

That reading covered 10,058 recalls in the CPSC's recall database, 381 product safety warnings across all 39 pages of its warnings list, and 2,276 news releases across all 233 pages. It finds the CPSC's e-bike recalls of other makers, Ancheer's and FENGQS's among them, and both of its warnings on Ridstar bikes, so a notice naming Qlife would have shown.

The TÜV Rheinland certificates, model by model

Thirteen of the 19 bike pages say the battery pack "has been tested to ANSI/CAN/UL/ULC 2271:2018 by TUV Rheinland" and the electrical system "tested and certified to ANSI/CAN/UL 2849:2022A by TUV Rheinland", and the Cityone Plus page calls its battery "TÜV Certified".

TÜV Rheinland publishes its certificates on Certipedia, and the register lists eight held by HONG KONG HONGDA NEW ENERGY CO., LIMITED, the company Qlife's privacy policy names, at a Kwun Tong, Kowloon address.

Seven of the eight are for an "Electric System for Electric Bike" to ANSI/CAN/UL 2849:2022A, issued from December 15, 2025 to June 29, 2026; the eighth covers an "Electric System for E-Mobility Devices" to ANSI/CAN/UL 2272:2024 (CU 72608266).

A second holder, Tianjin Zhiqing Mingtu Intelligent Technology Co., Ltd., holds three more e-bike electrical-system certificates to UL 2849:2022A. The table lists every certificate of the two holders whose model list names each Qlife model.

Vela S1 none of the 22 certificates read none of the 22 certificates read

The Vela S1 is the one current listing named on none of the 22 certificates read for the two holders. If you are buying a Vela S1, ask Qlife in writing for the certificate number that covers it, and check that number on Certipedia before you order.

Tianjin Zhiqing Mingtu also holds eleven ANSI/CAN/UL/ULC 2271:2018 battery-pack certificates. They name pack part numbers rather than bike models, so none can be tied to a Qlife model from the register alone: ask Qlife which certificate covers the battery on the bike you are buying.

Each card below lists its maker's own motor rating and battery, read at the maker on October 24, 2026.

The Qlife eBike lineup in the US: 19 listings, side by side

Qlife's US store listed 19 single bikes on October 23, 2026, under 17 model names, from $529 to $1,399, so you are choosing among six families: the moped-style Spark, the fat-tire and mountain Racer, the folding Hunter, the Cityone commuter, the Qlife Triker three-wheelers and the Vela electric dirt bikes.

Prices are the variant prices each listing showed on October 23, 2026; watt-hours are Qlife's volts times its amp-hours. Where a Qlife page and its product record disagree, the table prints the page and Limitations lists the record's figure. For agents and spreadsheets, all 19 rows, with each listing's class label, water rating, charging time, range, certificates and law counts, download as a CSV file and its JSON twin.

The Spark family

If you want the moped look, the Spark is Qlife's moped-style bike: a long flat seat, a motorcycle-style headlight and 20 x 4.0-inch fat tires on front and rear suspension. Its specification table lists a 1,800 W peak motor, 35+ mph, a 48 V, 15.6 Ah battery, 93 lb, a 360 lb maximum payload and riders from 5'3" to 6'3".

Qlife lists the same Spark twice. The older listing priced its variants from $699 to $899 on October 23, 2026, and a second listing, published October 12, priced the same single-battery, rack and dual-battery options from $1,099 to $1,299. Check which page your cart came from.

The Spark Plus moves to a 52 V, 20 Ah battery, hydraulic disc brakes, a 2,200 W peak motor and 140 N·m, at $999. The Spark Max adds a second motor, for 3,000 W peak and 200 N·m, at $1,399. Both pages print 38+ mph.

Spark, Spark D2 or Spark Plus?

Pick by your rider's size first. The Spark D2 rolls on 16 x 4.0-inch wheels, weighs 78.7 lb against the Spark's 93, and prints 30+ mph against 35+, with the same 48 V, 15.6 Ah battery, for $649 to $729. Qlife's comparison table on the Spark Plus page gives it 85 N·m against the Spark's 110.

If you want a bigger battery and hydraulic brakes, the Spark Plus is the step up: 52 V and 20 Ah against 48 V and 15.6 Ah, and hydraulic discs where Qlife's table lists plain disc brakes for the Spark and the D2.

The Spark Plus record calls it "designed for young riders", and the Spark Max's record says the same of it ("built for young riders"); read age and the young rider before buying either for a teen.

The Racer family

The Racer bikes are Qlife's fat-tire and mountain line, and you choose among them by tire size, suspension and speed. The original Racer rides 20 x 4.0-inch tires at 59.5 lb and 28 mph, and the Racer Plus moves to 26 x 4.0 inches at 67.5 lb. Both carry a suspension fork and a seven-speed drivetrain, at $569 to $749.

The 2.0 versions add full suspension and a bigger battery: the Racer 2.0 prints 1,800 W peak and 35+ mph on 20-inch tires, and the Racer Plus 2.0 prints 37+ mph and a 48 V, 20 Ah battery on 26-inch tires.

The Racer Max is the heaviest of them, 90.39 lb, with two motors ("1500W front + 1500W rear" in its record), hydraulic brakes, full suspension and a 52 V, 20 Ah battery, at $1,099 to $1,149. The Racer Ultra is the odd one out: a 27.5 x 2.1-inch full-suspension mountain bike with 21 speeds, a 1,200 W peak motor and 28 mph, at $549 to $559.

Hunter and Hunter Plus

If you need a bike that folds, the Hunter does, and its product record pitches it at "delivery, courier, and work riders". The Hunter carries a 500 W motor in its record (1,500 W peak on the page), a 648 Wh battery, 20 x 3.0-inch tires, a 400 lb maximum payload and a 120 lb rear rack, at 60.49 lb, from $529.

The Hunter Plus moves to 20 x 4.0-inch tires and a 48 V, 20 Ah battery. Its record describes "a 750W motor with 1800W peak output" and 32 mph, and the bike weighs 79.3 lb, from $699.

Cityone Plus

For your commute, the Cityone Plus is Qlife's commuter: a step-through frame, an upright position, 26 x 2.1-inch tires, a suspension fork and seven speeds. Its record gives "500W (1500W peak)" and 28 mph (the page prints 1,200 W peak), with a 48 V, 15 Ah battery, 70.55 lb and a 350 lb payload, from $599.

Qlife Triker 2.0 and Qlife Triker Plus

If you need three wheels, both of these fold, and both pages print a 1,200 W peak beside a lower figure: "a 48V 350W motor (1200W peak)" on the Qlife Triker 2.0 and "a reliable 500W rated motor" on the Qlife Triker Plus.

The Qlife Triker 2.0 rides 18 x 3.0-inch tires, weighs 97 lb, carries 400 lb and prints 18 mph, with what its record calls its "advanced smart differential". It, too, is listed twice: from $629 to $679, and from $1,099 to $1,149 on a second listing published October 14.

The Qlife Triker Plus moves to 20 x 4.0-inch fat tires and a 500 lb payload, at 108 lb and $899. Its page answers its own question in one line: "The QLIFE Triker Plus is a Class 2 electric trike, with a top speed of 20 mph."

Vela E8 and Vela S1

If you are shopping the Velas, you are shopping electric dirt bikes. The Vela E8 prints a 4,000 W peak mid-drive motor, 40+ mph, a 48 V, 25 Ah battery and 14-inch front, 12-inch rear wheels at 114.6 lb, for $999. The Vela S1 prints "1500W rated power, 3500W peak output", 42+ mph and 19-inch front, 17-inch rear motorcycle tires, at $1,299.

Qlife's own Vela E8 manual calls it an "Electric motorcycle" and says, on its warning page: "The user age must be 13+. For off-road use only." In red, the same page adds: "Not intended for use on public roads." Qlife's dirt bike collection says the Vela line "is designed for recreational off-road riding".

Which top speed to plan on

Plan the law on both figures, and plan your range on the manual's.

Sixteen of the 19 Qlife pages print 28 to 42+ mph, while the parameter tables of the Spark, Spark Plus, Spark Max, Racer Plus 2.0 and Racer Max manuals print "Maximum Speed 28MPH", the other Racer manuals' assist tables top out at 28 mph, and the Spark D2's table prints 25 mph. Each figure is Qlife's, and where a Qlife stands shows you the law at each.

For range, the manuals are the conservative source. The Spark Plus manual prints 35 to 45 miles in throttle mode and 50 to 60 on pedal assist, where its page prints "UP TO 90 Miles" and its product record "a tested range of up to 41 miles (66 km)". Plan a commute on the lowest of the three.

Older Qlife names you will still see

Qlife's manuals page still links manuals for models its store no longer lists as bikes: the Vela E5 (its manual prints "Max Speed 58KM/H"), the Cityone ST (the About page's 2022 bike) and its step-over sibling, still named on a spare-battery listing, the Racer Step Over in 26 and 27.5 inches (Qlife's 2021 "first creation") and the original Qlife Triker.

If you shop used, you will still meet these names on listings and marketplace pages.

Two-bike bundles, batteries and parts

Qlife sells two-bike "Combo Sale" bundles, 17 of them on October 23, 2026, from $1,098 to $2,799 (two Spark Max). The rest of the store is 86 parts, accessory and service listings, among them spare batteries from $199, controllers, displays, throttles, wheels, racks and fenders you can order for a Qlife you already own.

Each card below sits beside a Qlife model, on a rated motor and a top speed that its maker's specification holds to 28 mph or less.

Match a Qlife to a bike we sell

Our picks: a bike we sell beside each Qlife

We do not sell Qlife. Each card below sets a bike we do sell beside the Qlife it matches, so you can compare like with like: every one has one motor, rated at or under the figure Qlife prints for the model beside it, and a top speed its maker's specification puts at 28 mph or less. Nine bikes from six makers stand beside ten of Qlife's 17 current models.

Samebike VOYAGER

$899 · maker's list $1,499

With the VOYAGER you keep what makes a Spark comfortable, fat 20 x 4.0-inch tires and suspension at both ends, on a 750 W rated motor. Samebike's VOYAGER page lists a 1,500 W peak, 85+ N·m, a 48 V, 20 Ah battery (960 Wh, larger than the Spark's 749 Wh), hydraulic disc brakes and a 45 km/h (28 mph) top speed in its specification table.

Lower on the same page, you will find one motor panel printing "1000W (Peak 1800W)" and "max 50KM/H" (31 mph). Samebike lists it at $999 with the rear rack and fenders, and on October 30, 2026 its page offered $100 off at checkout with code BF100; the $899 you pay here already includes that $100, rack and fenders in the box.

The Qlife models without a card

Seven of Qlife's 17 current models have no card of their own. The Racer and Racer 2.0 roll on 20 x 4.0-inch fat tires, the VOYAGER's size, and the Racer Plus and Racer Plus 2.0 on 26 x 4.0, the D5 2.0's, so those two cards are the place to start.

The Racer Ultra is a full-suspension mountain bike on 27.5 x 2.1-inch tires at $549 to $559, and none of the nine bikes above is one; for that ride, start with our electric mountain bike guide.

Qlife's own manual calls the Vela E8 an "Electric motorcycle" and says "For off-road use only", and its dirt-bike collection says the Vela line "is designed for recreational off-road riding", so no e-bike card stands beside either Vela. For a young rider, our kids and teens guide matches e-bikes we sell to your child's height and your state's age rule.

Why buy one of these from us

Every card sells at a price read against its maker's own store on October 24, 2026, and our terms of service name the company your order is with. One address covers all six makers for you, support@redtailebikes.com, and our contact page says we typically reply within one business day.

Every e-bike ships free within the contiguous United States: we dispatch within 1 to 3 business days of order confirmation, and most bikes arrive within 5 to 10 business days after dispatch (our shipping policy).

If a bike arrives damaged, email photos within 48 hours and we file the carrier claim; a defect goes under its maker's warranty, and we coordinate the repair (our refund policy). Checkout takes Shop Pay, plus Apple Pay or Google Pay on the browsers and devices that offer them.

How we matched each bike

A card appears beside a Qlife only when our bike's rated motor is at or under the figure Qlife prints for that model and the top speed in its maker's specification is at or under Qlife's. Where Qlife prints only a peak figure, or a figure above 750 W, the card's own motor is rated at 750 W or less. Every card has one motor.

Where a maker's page prints a second motor or speed figure outside its specification table, the card prints that one too, so you see both.

Each maker's US store was read for its price, stock and the specification on the card, and owner feedback on each bike was read before it went on the page. Where a maker's checkout code takes money off, the price you pay here already includes it and the card names the code; where our listing offers a color its maker showed sold out, the card's button adds a color the maker had in stock.

Speed, class and the law: where a Qlife stands

At the top speeds Qlife's pages print, every two-wheel Qlife sits outside the e-bike definition in 49 of the 51 US jurisdictions, and the lower top speeds in Qlife's owner's manuals give the same answer. Alaska and Kentucky write no e-bike definition into their codes, so neither has a line to sit inside or outside.

The two Qlife Triker models run the other way: inside 39 and 38 definitions on the motor and speed figures Qlife prints.

What the three classes allow

The Bureau of Land Management's rule for federal public lands sets out the three-class model in one place. It defines an e-bike as "a two- or three-wheeled cycle with fully operable pedals and an electric motor of not more than 750 watts (1 h.p.)" that meets one of three classes (43 CFR § 8340.0-5(j)).

Class 1 and Class 3 help "only when the rider is pedaling", and they stop helping when the bike reaches 20 and 28 miles per hour. A Class 2 motor "may be used exclusively to propel the bicycle", and it "is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour". Each state writes its own definition in its own words, and your state's wording is the one that decides your bike.

Where every two-wheel Qlife stands

Qlife's pages print top speeds from 28 to 42+ mph for its 15 two-wheel models, and its manuals give the throttle a top speed of its own. The Spark Plus manual reads: "With throttle only (no pedaling) top speed is up to 28 MPH". Its assist ladder runs from 9 mph in PA1 to 28 mph in PA5, and "If not pedaling, the set PA's top speed is the throttle top speed."

A throttle that keeps pushing past 20 mph takes a bike out of Class 2, and assistance past 28 mph takes it out of Class 3. Each two-wheel Qlife reads outside 49 definitions on its printed speed and its throttle alone, before any motor figure is weighed, at the page's top speed and at the manual's.

Qlife's own article on moped-style bikes draws the same line:

Officially, there are only three e-bike classes in the US. However, many models fall outside these three classes.

Among the article's signs that a bike has crossed that line are "Exceeds 28 mph (beyond Class 3 limits)" and "Operates on throttle only without the need to pedal", and it says such a bike "will be classified as a motor vehicle or moped, requiring a license, insurance, and registration" (Qlife, "Are Moped-Style E-Bikes Legal?").

The line to check first A throttle that keeps driving the bike past 20 mph, or assistance past 28 mph, takes it outside the three classes. Read your own state's definition, and ask Qlife in writing for the speeds and motor rating of the model you want, before you ride one on the road.

Lower assist levels, and what the law leaves open

A lower assist level slows a Qlife: on the Spark Plus, PA1 stops at 9 mph and PA3 at 17. Whether a level you can switch back counts as the bike's top speed is unsettled. The federal Class 2 test asks what the motor "is not capable of", and that reads two ways: as the bike in the level it is ridden in, or as the bike at the highest level it carries.

The verdicts here take the second reading, the speed Qlife prints for each model. Before you rely on a lower level, ask your state's motor vehicle agency in writing how it treats one.

What riding outside the definition can cost

Outside the e-bike definition, a Qlife is whatever else your state's code makes it, and the stakes turn on that provision.

In New Jersey, a bike with "an electric motor that is capable of propelling the bicycle in excess of 15 miles per hour through the use of a throttle with a maximum motor-powered speed of no more than 28 miles per hour on a flat surface" is a motorized bicycle (P.L.2025, c.285, amending R.S. 39:1-1). That describes the two-wheel Qlife you would ride at the 28 mph its manual gives the throttle.

On New Jersey's highways, a motorized bicycle's operator must carry "The valid driver's license, the insurance identification card, and the registration certificate", and a rider without them faces "a fine not exceeding $50" under N.J.S.A. 39:4-14.3(e), as amended by P.L.2025, c.285, § 5, in force since its approval on January 19, 2026.

On land run by the Bureau of Land Management, a machine outside the e-bike definition gets no e-bike exclusion: it is an "off-road vehicle", "any motorized vehicle capable of, or designed for, travel on or immediately over land" (43 CFR § 8340.0-5(a)).

Breaking the off-road vehicle rules of subparts 8341 and 8343 can bring "a fine of not more than $1,000 or imprisonment for not longer than 12 months, or both" (43 CFR § 8340.0-7).

Where the Qlife Triker models stand

At the 350 W and 18 mph its page prints, with a throttle, the Qlife Triker 2.0 sits inside the e-bike definition in 39 of the 51 jurisdictions, and the Qlife Triker Plus, at 500 W and 20 mph, in 38.

Both sit outside four definitions written for two wheels, Alabama's, Idaho's, Montana's ("two tandem wheels", MCA § 61-8-102(7)) and Rhode Island's, and outside New Jersey's, where a bike with a throttle is a motorized bicycle.

The Qlife Triker Plus, at 108 lb, is also outside Pennsylvania's definition, written for "A vehicle weighing not more than 100 pounds" (75 Pa.C.S. § 102). In Arkansas, Connecticut, Missouri, New York and Vermont, whether a three-wheeler counts is unsettled, so no verdict is given there.

Both Qlife Triker pages also print a 1,200 W peak, and the Qlife Triker Plus page's comparison table lists the Qlife Triker 2.0 at "Peak 750W". Ask Qlife in writing for the rated figure of the trike you are buying before you lean on these counts.

Our law hub sets all 50 states side by side in one table, each linked to that state's own law page.

Open your state's e-bike law

Age and the young rider

Qlife's records call two Spark trims bikes for "young riders", but a two-wheel Qlife sits outside the e-bike definition in 49 jurisdictions at the speeds Qlife prints, so the e-bike age rules do not settle who may ride one there. The licensing rules for the vehicle your state counts it as do.

What Qlife says about age

The Spark Plus record says it "is designed for young riders who value power, style, and control", the Spark Max record that it "is built for young riders who want maximum power", and the Spark record that it was "crafted for both students and adults". Both Vela listings, the Vela E8 and the Vela S1, are titled "for Teens & Adults", and the Vela E8 manual says "The user age must be 13+. For off-road use only."

Qlife's article on moped-style bikes sets a higher age for a bike outside the three classes: "You'll need to be over 16 years old and have a license and registration to ride one." Its dirt bike collection says the Vela E8 "is marketed for teens and adults, not as a toy". Read them together before you buy a Qlife for a rider under 17.

What the law sets

New Jersey's P.L.2025, c.285 draws the line for motorized bicycles in three steps: "No person who is under 15 years of age shall be permitted to operate a low-speed electric bicycle or motorized bicycle", a rider of 15 or 16 needs a motorized bicycle license or permit, and a rider of 17 or older needs a basic driver's license or a motorized bicycle license or permit (P.L.2025, c.285, § 5).

Every other state writes its own rules for the vehicle a fast Qlife counts as, so check yours before your teen rides.

Our kids and teens guide matches e-bikes we sell to a child's height and your state's age rule, and every one ships free to the lower 48.

Qlife's warranty, returns and shipping, clause by clause

If you buy from Qlife, you get one year on the frame, battery and components, 14 days from delivery to return a bike with $200 deducted for a change of mind, and shipping from US warehouses, typically within 1 to 2 business days. Two of those terms read differently in two places, and both readings are printed below.

The warranty

Qlife's warranty page says "All Qlife electric bicycles come with a one-year manufacturer's warranty covering manufacturing defects for the original owner". The frame, battery and components each carry one year; "Labor costs associated with replacing the frame are not covered", and "The owner is responsible for shipping costs for replacement components supplied under warranty."

Qlife's warranty page starts that year in two places. Its eligibility section says the period "begins on the date the original owner receives the bicycle"; its frame section counts "one year from the original retail purchase date", and claims are handled "within one year of the original retail purchase date". Ask Qlife to confirm the start date in writing when you order.

A later owner inherits the rest of the year only on the page's two conditions, and Qlife "will not ship replacement components until photos or videos of the affected area have been reviewed".

Returns

Qlife's return policy takes a return "within 14 days of delivery", with Customer Support's approval first. If you change your mind, "a total fee of $200, covering return shipping and handling, will be deducted from your refund", and the bike must be unridden, show "fewer than 10 miles" and come back in its original packaging; an unauthorized return "may be refused or subject to a 25% restocking fee".

Under the same policy, a defect or shipping damage goes to Customer Support "within 7 days of receipt", with photos or video. It asks you to keep the original packaging "for at least 14 days after receiving your bicycle".

Qlife's separate refund policy reads differently. It allows a new, unused item back after the 14 days with "a restocking fee in the amount of twenty percent (20%) of the purchase price", and in another clause rules out a restocking fee "for the return of a product". Ask Qlife which document governs your order before you send a bike back.

Shipping and payment

Qlife's shipping policy says e-bikes "Typically ship within 1–2 business days" and "Typically arrive 3–7 business days after shipping", and that its estimates "are not guaranteed". Qlife's payment page says it supports "PayPal, Klarna installment payment, and credit/debit cards".

Every bike we sell ships free to the lower 48, damage photographed within 48 hours of delivery is a carrier claim we file, and we coordinate warranty repairs with its maker.

Compare our nine bikes

Before you buy a Qlife: the checklist

Nine checks, in the order you meet them: the law, the listing, the motor, the certificate, the rider, then the terms.

  1. Your state's line. Read the page's top speed and the manual's, then where a Qlife stands: at Qlife's printed speeds, a two-wheeler sits outside the e-bike definition in 49 jurisdictions.
  2. The listing in your cart. The Spark and the Qlife Triker 2.0 are each listed twice, at different prices; check which page your cart came from.
  3. The motor rating. Where Qlife prints only a peak figure (the Spark, the Spark Max, the six Racers and the Vela E8), ask Qlife in writing for the rated figure.
  4. The certificate. Ask Qlife for the TÜV Rheinland certificate number that names your model, and look it up on Certipedia; the Vela S1 is named on none of the 22 certificates its two holders list.
  5. The rider. Set Qlife's own age statements (13+ in the Vela E8 manual, over 16 with a license in its moped article) beside your state's rules.
  6. The warranty start. Get the start date, receipt or purchase, in writing.
  7. A change of mind. Budget $200 for return shipping and handling, and keep the bike unridden, under 10 miles and boxed for 14 days.
  8. Delivery day. Inspect the bike when it arrives; Qlife asks for defect and damage reports within 7 days, with photos or video.
  9. One channel. Qlife prints three phone numbers, so put questions to service@qlifebike.com and keep the replies.

The honest ledger

The left column is what Qlife does well, by its own records and the public registers. The right column says who should look at another bike first, and where to look.

Frequently asked questions

Is Qlife a good e-bike brand?

Qlife sells fat-tire, moped-style, folding and three-wheel e-bikes from $529 to $1,399, with a one-year warranty and TÜV Rheinland certificates naming the models of 18 of its 19 listings. No CPSC recall, warning or news release named Qlife on October 23, 2026. The question that decides it for you is speed: at Qlife's printed figures, its two-wheelers sit outside the e-bike definition in 49 jurisdictions (where a Qlife stands).

Who makes Qlife e-bikes, and who owns the brand?

Qlife's privacy policy names HONG KONG HONGDA NEW ENERGY CO., LIMITED, and TÜV Rheinland lists that company and Tianjin Zhiqing Mingtu Intelligent Technology Co., Ltd. as holders of certificates naming Qlife models. The USPTO record lists Tianjin Weizhixing Technology Co., Ltd as owner of the QLIFE bicycle trademark. None of those records names a factory, and four of Qlife's 23 manuals print "MADE IN CHINA"; if you need the factory, ask Qlife in writing.

Where are Qlife bikes made?

Four of the 23 owner's manuals Qlife links print "MADE IN CHINA": the Qlife Triker Plus manual, the original Qlife Triker's and the two Racer Step Over manuals. The Spark's product record calls it "proudly designed in sunny Florida", and Qlife's shipping policy says "All orders ship directly from our U.S.-based warehouses".

Where does Qlife ship from, and how long does delivery take?

From US warehouses. Qlife's shipping policy says e-bikes "Typically ship within 1–2 business days" and "Typically arrive 3–7 business days after shipping", estimates it says "are not guaranteed". Every bike we sell ships free within the lower 48: we dispatch within 1 to 3 business days of confirmation, and most arrive within 5 to 10 business days after dispatch (our shipping policy).

Is Qlife legit?

Qlife sells direct from qlifebike.com, a store whose record lists Sheung Wan, Hong Kong, and it publishes a warranty, a return policy and US warehouse shipping. QLIFE is a registered US trademark for bicycles, Reg. No. 6,353,539, and TÜV Rheinland lists certificates naming its models. Whoever you buy from, keep every term in writing.

At the top speeds Qlife's pages print, and at the 28 mph its manuals give the throttle, every two-wheel Qlife sits outside the e-bike definition in 49 of the 51 US jurisdictions, and Alaska and Kentucky define none. Outside it, your state decides what a Qlife is: in New Jersey, you need a license, insurance and registration. The two Qlife Triker models sit inside 39 and 38 definitions (the read, state by state).

What class is the Qlife Racer?

Qlife's Racer page labels it "Class 3" beside a printed 28 mph, and the Racer manual says "With throttle only (no peddling) top speed is up to 28 MPH". Federal Class 3 assistance works "only when the rider is pedaling", so that throttle takes the Racer outside Class 3 and Class 2 alike, and outside 49 definitions; read your state's before you ride (where a Qlife stands).

How fast does a Qlife Spark go?

Qlife's pages print 35+ mph for the Spark, 38+ for the Spark Plus and Spark Max, and 30+ for the Spark D2. The manuals print less: "Maximum Speed 28MPH" in the Spark, Spark Plus and Spark Max manuals, and 25 mph in the Spark D2's parameter table. On the Spark Plus, the assist levels you choose run from 9 mph in PA1 to 28 mph in PA5 (Spark Plus manual).

Can you unlock the speed on a Qlife Spark?

Qlife's own article lists a bike that "Exceeds 28 mph (beyond Class 3 limits)" among those it says "will be classified as a motor vehicle or moped, requiring a license, insurance, and registration" (Qlife, "Are Moped-Style E-Bikes Legal?"). At the speeds Qlife already prints, a two-wheel Qlife sits outside the e-bike definition in 49 jurisdictions, and a faster setting keeps it there.

Are Qlife e-bikes UL certified?

TÜV Rheinland's public register lists UL 2849 certificates, for the e-bike's electrical system, whose model lists name 17 of Qlife's 19 listings, and a UL 2272 certificate for the Vela E8 (CU 72505469 is one). The Vela S1 is named on none of the 22 certificates its two holders list. Ask Qlife for the certificate number that names your model, and read the certificate table.

Are Qlife e-bikes safe?

No CPSC recall, product safety warning or news release named Qlife or a Qlife model when all three registers were read on October 23, 2026 (CPSC recalls), and TÜV Rheinland lists certificates naming the models of 18 of the 19 listings. On the road, your speed matters as much: Qlife's pages print up to 42+ mph, and its Vela E8 manual says that bike is "Not intended for use on public roads."

Are Qlife e-bikes waterproof?

Qlife's own answer sets the limit for you: its Qlife Triker 2.0 page says the bike "has an IP54-rated waterproof design, suitable for light rain. However, avoid deep water or heavy storms." Its specification tables give "IP Level IPX5" on 14 of the 19 listings, and the Spark Plus manual prints IP54 for the same bike.

How far does a Qlife go on one charge?

Qlife's pages print "up to" 55 to 90 miles, depending on the model (the range column of our Qlife dataset), and its manuals print less: the Spark Plus manual gives 35 to 45 miles in throttle mode and 50 to 60 on pedal assist, and the Spark D2 manual 18 to 22 and 20 to 25. Plan a commute on the manual's lower figure for your model.

How long does a Qlife battery take to charge?

Qlife's specification tables give 4 to 6 hours for the Spark, Racer, Racer 2.0, Racer Plus, Racer Ultra and Qlife Triker 2.0, and up to 9 to 11 hours for the two-motor Racer Max, with its 52 V, 20 Ah pack (the charging-time column of our Qlife dataset). The pack comes off for charging: Qlife's FAQ says "The battery is designed to be removable, allowing you to charge it anywhere."

How do you turn on a Qlife e-bike?

From the display. The Spark Plus manual says you press and hold the power button "In the off state": the display enters "the boot interface after 1 second" and "the riding interface after 2 seconds". A long press of the light button turns on the front, rear and brake lights (page 13), and the Racer Fat Tire manual prints the same power steps.

Are Qlife trikes any good?

Qlife sells two folding three-wheelers: the Qlife Triker 2.0, 350 W and 18 mph from $629, and the Qlife Triker Plus, 500 W rated and 20 mph at $899, with 400 and 500 lb payloads. At those figures they sit inside the e-bike definition in 39 and 38 jurisdictions. If you want the same footing from a store that ships free, the Hera and the ONE-TRIKE 2.0 stand beside them.

Is there a throttle that will work with a Qlife?

Qlife sells its own: a Racer Throttle and a Commuter Thumb Throttle at $39 each, and a Throttle handle at $59, among its 86 parts, accessory and service listings. Match the part to your model with Qlife before you order, since a throttle is part of the bike's speed control.

The bottom line

A Qlife is a direct-sold fat-tire, moped-style, folding or three-wheel machine at $529 to $1,399, with a one-year warranty and TÜV Rheinland certificates that name the models of 18 of its 19 listings. At the speeds Qlife prints, its two-wheelers sit outside the e-bike definition in 49 jurisdictions, so read where a Qlife stands before you buy one for the road; its two trikes sit inside 39 and 38.

If you want the ride with a top speed its maker specifies at 28 mph or less, from a store that ships free and coordinates the warranty with the maker, these are the nine bikes we sell beside a Qlife, each read at its maker for price and stock on October 24, 2026:

Not sure which? Send your rider's height, weight and usual route to support@redtailebikes.com, and we will reply with the card that fits before you order.

Each card ships free to the lower 48, and damage photographed within 48 hours of delivery is a carrier claim we file.

Back to the nine cards

Image credit: the nine bike photographs on the cards are their makers' own (Samebike, Qiolor, VTUVIA, Himiway, DWMEIGI and Eunorau), each in the colorway its card adds, scaled or cropped only; the CY20 Pro's is cut from its white background into a generated autumn street, and no bike's pixels are retouched.

Cover: Qlife's own studio photograph of the Spark in Red, cut from its white background and scaled whole, its pixels unchanged. The studio around it was generated with Nano Banana Pro on Playcut, and the cover type was set on top afterward.

Limitations

Interest

  1. Redtail eBikes does not sell Qlife. We sell the nine bikes on the cards, and we earn from those sales.

Data

  1. Every Qlife figure here is Qlife's own, read on its US store in US dollars on October 23, 2026, with its manuals, blog and policies; the nine cards' prices, stock and specifications were read at their makers on October 24. Prices, stock and terms change, and each figure carries its date.
  2. Speed figures that disagree: the Spark Plus record gives 37 mph, the Racer Plus 2.0 record 28 mph and the Racer Max record 37 mph, against 38+, 37+ and 38+ on their pages; the Racer 2.0 record prints both "up to 28 mph" and "35+ MPH". The Spark D2 manual's parameter table prints 25 mph and its assist table 28 mph.
  3. Motor figures that disagree: the Racer and Racer Plus records give a 1,200 W peak against 1,500 W on their pages, the Racer Plus 2.0 record 1,500 W against 1,800 W, the Cityone Plus record a 1,500 W peak against 1,200 W, and the Spark D2 record a 2,000 W peak against 1,800 W. The Racer family's FAQ tabs print "Motor: 1000W Peak".
  4. The Qlife Triker Plus page's comparison table lists the Qlife Triker 2.0 at "Peak 750W", "36V 13Ah" and "Up To 50 Miles", against a 1,200 W peak, 48 V, 10.4 Ah and 55 miles on the Qlife Triker 2.0's own page, and the Qlife Triker 2.0 page's own comparison table gives it "68LBS" against "E-Bike Weight 97 LBS" in its specification; the law read uses the 350 W in the Qlife Triker 2.0 page's text.
  5. Battery, weight and load figures that disagree: the Racer Plus 2.0 record gives 15.6 Ah against 20 Ah on its page, and its manual 75.4 lb against 67.5 lb on its page and a 360 lb load against 350; the Vela E8 record gives 23 Ah against 25 Ah; the Spark D2 manual gives 82 lb against 78.7 lb; the Hunter's feature text gives its rack "up to 400 lbs" against "Rear Rack Capacity 120 lbs" in its table. The lineup table prints the page's figure in each case.
  6. Range and water ratings: the Spark Plus page prints "UP TO 90 Miles", its record "a tested range of up to 41 miles (66 km)" and its manual 35 to 45 and 50 to 60 miles; the Spark D2 manual prints 18 to 25 miles against 65 on its page. The Spark Plus manual prints IP54 against IPX5 in its page's table.
  7. Class labels: Qlife's tables label 15 listings "Class 3" and four "Class 2" (the Racer Ultra and the three Qlife Triker listings); the Spark Plus page's comparison table lists the Spark as "Class 2", against "Class 3" on the Spark's own page. Each label is reported as Qlife's, and the verdicts read each statute.
  8. The Racer Ultra's linked manual prints Racer Max figures (26 x 4.0-inch tires, 52 V, 90.39 lb) in its parameter table, so the Racer Ultra row uses the 48.1 lb in its product record.

Method

  1. The law read runs Qlife's printed figures, from the page and the manual, through each jurisdiction's e-bike definition in our state-by-state rule table, with each statute's own boundary word. A setting a rider can change is not modeled, because the law on it is unsettled (assist levels). It is a reading of published figures and statutes, not legal advice.
  2. A statute, regulation or regulator's record has one publisher, so those rows carry SOLE-PUBLISHER in the citation ledger; each was read in two copies where two exist: the eCFR and the Federal Register or the CFR annual edition for the Bureau of Land Management rule, and the act's HTML and PDF texts for New Jersey's P.L.2025, c.285.
  3. 21 of the 23 manuals carry under 200 characters of text a page, so their text was machine-read from the page images; every manual page quoted here was checked against its image, and the search for a country of manufacture read each manual's last four pages.
  4. The CPSC reading covered 10,058 recalls, 381 warnings over 39 pages and 2,276 news releases over 233 pages, for Qlife, Qlife Bike, each model name and the four companies on Qlife's records; the same reading finds other makers' e-bike recalls.
  5. The battery certificates name pack part numbers, and the 23 manuals' machine-read text carries none of them, so no battery certificate is tied to a Qlife model here.
  6. Each card photo is its maker's own photograph, pixels untouched; the CY20 Pro's is cut from its background into a generated autumn street.
  7. The questions this page answers were harvested on October 23, 2026 from Google, Bing and DuckDuckGo autocomplete (1,338 distinct suggestions, 131 of them questions naming Qlife), Reddit and the headings of the pages ranking for Qlife; the AI-answer panel was run through a web-search tool because the browser route failed its control that day.

Expiry conditions

This page is accurate as of October 24, 2026. It ages when any of these happens:

  1. Qlife changes its lineup, prices, specifications, warranty, return or shipping terms (read October 23, 2026).
  2. The CPSC publishes a recall, product safety warning or news release naming Qlife or a Qlife model.
  3. TÜV Rheinland adds, withdraws or changes a certificate naming a Qlife model.
  4. The USPTO records a new owner or a change of status for QLIFE, Reg. No. 6,353,539.
  5. A state changes its e-bike definition in a way that moves a Qlife across a line counted here.
  6. A maker changes the price, stock or specification of a bike on the cards (read October 24, 2026), or Samebike's codes end: BF100 and BF80 take $100 off the VOYAGER and $80 off the CY20 Pro, and our two prices include them.
