VTUVIA's lineup on our shelf, model by model: our VTUVIA collection, with the six machines VTUVIA can ship today each priced against VTUVIA's own US store on September 30, 2026, each specification read on VTUVIA's product pages, and the brand name searched in the federal recall register and the US trademark register.
Quick Answer VTUVIA says it was founded in Los Angeles in 2016, and its US trademark is registered to Changzhou Vtuvia Motor Technology Co., Ltd. We can ship six VTUVIA machines today: the $1,099 Zeal LT7, the $1,299 SF20H and SX20 folders, the $1,399 Zeal XT8 and CMB 8-Speed, and the E-Cozy trike from $2,099.
All six ship as Class 2, with a throttle and pedal assist to 20 mph. Pick by frame and load first. The two folders fit a trunk, the SF20H carries a second rider on its rear seat, the two Zeals and the CMB are 27.5- and 26-inch commuters, and the E-Cozy is a three-wheeler rated for 450 lb.
The class section sets each motor against the 750 W lines in federal and California law.
How we verified this brand profile. On September 30, 2026 we read every VTUVIA price and stock level beside VTUVIA's own US store, and every specification from VTUVIA's product pages, records and posts. The trademark record is the USPTO's and the recall count the CPSC's. Range and fit are computed from published physics and a survey of 6,068 bodies, set out in full in four of our VTUVIA reviews.

Which VTUVIA fits you
VTUVIA sells four kinds of machine, so choose the kind first. The SF20H and the SX20 fold on 20 × 4.0 fat tires. The Zeal LT7 and Zeal XT8 are 27.5-inch step-through commuters on one frame. The CMB 8-Speed puts its motor at the pedals, and the E-Cozy is a three-wheeler with a backrest.
Every price below is the one VTUVIA's own US store printed the same day, with VTUVIA's higher regular price shown as the maker's list, and every machine ships free to the lower 48. The quick way to choose:
| If you want | Choose | Our price |
|---|---|---|
| The lowest price, and a torque sensor | Buy the Zeal LT7 | $1,099 (maker's list $1,299) |
| A folder that seats a second rider | Buy the SF20H in White | $1,299 (maker's list $1,399) |
| A folder with the lowest step, from 5'0" | Buy the SX20 in Teal Blue | $1,299 (maker's list $1,599) |

The Zeal LT7 in Olive Green in VTUVIA's own studio photograph: the low step between seat post and head tube, and the rack and fenders it ships with.
VTUVIA Zeal LT7
$1,099 · maker's list $1,299The LT7 is the lower-priced of VTUVIA's two Zeals. VTUVIA's specification gives it a 500 W rear hub motor with a 750 W peak and 65 N·m. It reads your pedaling through a "V-Adapt™ Torque" sensor, and it runs a 48 V 13 Ah pack of 624 Wh, Shimano's 7-speed and 27.5 × 2.6 tires, at 62 lb with the rack and fenders.
VTUVIA prints 70 miles on pedal assist and 38 on the throttle for it, and a 350 lb total capacity. It shares the XT8's published frame lengths: an 18.5-inch step and a 35.4-inch lowest seat. For a 180 lb rider, our Zeal LT7 review computes 39 miles at a steady 15 mph on the throttle over level ground, and 63 with easy pedaling.
Choose it if you ride to work on pavement, stand between 5'3" and 6'2" (VTUVIA's window), and would rather keep $300 than take the XT8's air fork, eighth gear and turn signals. It comes in Lemon Yellow, or in Olive Green.

The SF20H in White in VTUVIA's own studio photograph: the folding frame, the 20 × 4.0 tires and the second seat on the rack.
VTUVIA SF20H
$1,299 · maker's list $1,399The SF20H folds and seats two. VTUVIA's specification gives it a 750 W rear hub motor with a 1,200 W peak and 85 N·m, a 48 V 14 Ah pack of 672 Wh, 20 × 4.0 tires and a 330 lb total capacity, at 60 lb. Its safety-certification row reads "UL2271(Battery） UL2849(E-bike System)".
Our SF20H review computes that pack at 37 miles for a 180 lb rider holding 15 mph on the throttle over level ground, and 56 with easy pedaling. It also sets the rear seat against California's passenger rule.
Choose it if the bike has to fold into a trunk or an RV bay and still carry a second person or a child seat. VTUVIA sizes it for riders from 5'3" to 6'2". It comes in White, or in Black.

The SX20 in Teal Blue in VTUVIA's own studio photograph: a 13.8-inch step on VTUVIA's product page, on the same 20 × 4.0 tires as the SF20H.
VTUVIA SX20 Antelope
$1,299 · maker's list $1,599The SX20 is VTUVIA's folding step-through. VTUVIA's specification gives it a 750 W rear hub motor with a 1,200 W peak and 85 N·m, a torque sensor, a 48 V 14 Ah pack of 672 Wh and 20 × 4.0 tires, at 70 lb with a 330 lb total capacity. The step is 13.8 inches on the product page and 15.4 on VTUVIA's size chart.
At 15 mph on the throttle with a 180 lb rider, our SX20 review works the pack out to 37 miles. It also finds the seat post reaching the formula's saddle height for 97 or more of every 100 riders from 5'0" to 5'8" in the US Army's survey.
Choose it if you stand between 5'0" and about 5'9" and want a step you can walk through. VTUVIA sizes it from 5'0" to 6'2". It comes in Teal Blue, Red, Cream White or Silvery.

The Zeal XT8 in Glacier White in VTUVIA's own studio photograph, its one colorway.
VTUVIA Zeal XT8
$1,399 · maker's list $1,799The XT8 is the larger Zeal. VTUVIA's specification gives it a 750 W rear hub motor with a 1,200 W peak and 85 N·m, a 48 V 15 Ah LG pack of 720 Wh, an 80 mm air fork with a lockout, Shimano's 8-speed and built-in turn signals, at 65 lb.
Level ground, 180 lb aboard and 15 mph on the throttle come to 45 miles in our Zeal XT8 review, and 74 with easy pedaling. VTUVIA's product page prints 80 miles on pedal assist and 50 on the throttle.
Choose it if you commute most days and want the lights and signals fitted, stand between 5'3" and 6'2", and keep rider and cargo inside VTUVIA's 350 lb. Glacier White is its one colorway.

The CMB 8-Speed in Dark blue in VTUVIA's own studio photograph: the motor sits at the crank, between the pedals.
VTUVIA CMB 8-Speed
$1,399 · maker's list $1,899The CMB is the one VTUVIA on our shelf with its motor at the pedals. VTUVIA's specification gives it a 500 W mid-drive with an 820 W peak and 175 N·m, cadence and torque sensors, a 48 V 14.4 Ah LG pack of 691.2 Wh, Shimano's 8-speed and 26 × 2.4 tires. It weighs 60 lb with a 300 lb total capacity, and its certification row reads "UL2271(Battery） UL2849(E-bike System)".
VTUVIA prints 80 miles on pedal assist and 45 on the throttle. Its seat runs from 31.5 to 39.4 inches off the floor, over a 16.9-inch step.
Choose it if you climb on your commute and like shifting through the gears, and stand between 5'1" and 6'1" with an inseam of 27 to 33 inches, VTUVIA's size guide says. It comes in Metallic Silver, or in Dark blue.

The E-Cozy in Forest Green in VTUVIA's own photograph: front and rear baskets, and the seat low over the frame.
VTUVIA E-Cozy
From $2,099The E-Cozy is VTUVIA's electric trike. VTUVIA's specification gives it a 750 W rear motor with a 1,200 W peak and 85 N·m, a torque sensor, a 48 V 15 Ah pack of 720 Wh, a reverse mode and a rear differential. It rides on 20 × 3.0 tires at 95 lb and carries a 450 lb total capacity.
VTUVIA prints 70 miles on pedal assist and 40 on the throttle. The step is 14.8 inches, and the seat runs from 27.2 to 37.0 inches off the floor, with a backrest.
Choose it if balance on two wheels is the worry, or the load is heavy. VTUVIA sizes it for riders from 5'1" to 6'3". VTUVIA lists it in Ruby Red, Forest Green, Pearl White and Lavender Purple, and on September 30, 2026 only Pearl White was in stock there; the Pearl White version with a suspension seatpost is $2,199.

Read the Zeal XT8 reviewAll nine VTUVIA machines on our shelf
We list nine VTUVIA machines. Three of them, the SN100, the Gemini and the Reindeer 2.0, were sold out in every variant at VTUVIA's US store on September 29, 2026, and we ship VTUVIA's bikes from VTUVIA's stock, so they carry no button here.
| Model | Our price (maker's list) | Motor · pack | VTUVIA's range figures | At VTUVIA, September 30, 2026 |
|---|---|---|---|---|
| Zeal LT7 | $1,099 ($1,299) | 500 W · 624 Wh | 70 mi assist, 38 throttle | orderable, 2 colorways |

| SN100 | $1,299 ($1,599) | 750 W · 672 Wh | 70 mi assist, 40 throttle | sold out |
| Gemini | $1,899 ($2,199) | 1,000 W · 1,092 Wh | 90 mi assist, 60 throttle | sold out |
| Reindeer 2.0 | $1,599 ($1,699) | 750 W · 672 Wh | 70 mi assist, 40 throttle | sold out |
Our prices and VTUVIA's, and stock at VTUVIA's US store, read September 30, 2026; motors are VTUVIA's rated figures and packs its published watt-hours, from each VTUVIA product page. The SF20H's Red and Dark Green, the SX20's White and the E-Cozy's Ruby Red, Forest Green and Lavender Purple were sold out at VTUVIA that day.
For a sold-out model, write to us and we will tell you the day VTUVIA lists it again. The SN100 is VTUVIA's fat-tire hunting bike, the Gemini its 1,000 W bike with two packs, and the Reindeer 2.0 a fat-tire step-through.
How far each VTUVIA goes
One division shows the riding each VTUVIA range figure describes. Divide each pack's watt-hours by VTUVIA's longest figure for it, and you get the energy a mile may use at that figure. The lower the number, the lighter the riding it describes.
| Model | Pack | VTUVIA's longest figure | Wh a mile it allows |
|---|---|---|---|
| CMB 8-Speed | 691.2 Wh | 80 mi, pedal assist | 8.6 |
| Zeal LT7 | 624 Wh | 70 mi, pedal assist | 8.9 |
| Zeal XT8 | 720 Wh | 80 mi, pedal assist | 9.0 |
| SF20H and SX20 | 672 Wh | 70 mi, pedal assist | 9.6 |
| E-Cozy | 720 Wh | 70 mi, pedal assist | 10.3 |
Each pack and figure from VTUVIA's product pages, read September 28, 2026. Watt-hours divided by miles is our arithmetic.
VTUVIA's throttle figures allow more per mile: 14.4 Wh for the XT8's 50 miles, 15.4 for the CMB's 45, 16.4 for the LT7's 38, 16.8 for the two folders' 40, and 18.0 for the E-Cozy's 40.
Four VTUVIAs have full reviews, and each review's range model turns VTUVIA's figures into steady rides you can plan on:
| Bike | 15 mph on the throttle | 15 mph, easy pedaling | Plan on, 75% of the throttle figure |
|---|---|---|---|
| Zeal LT7 | 39 miles | 63 miles | 29 miles |
| SF20H | 37 miles | 56 miles | 28 miles |
| SX20 | 37 miles | 56 miles | 28 miles |
| Zeal XT8 | 45 miles | 74 miles | 34 miles |
Each row comes from that review's model, built on VTUVIA's figures and Martin and colleagues' cycling-power model, for a 180 lb rider in still 77 °F air on level pavement; easy pedaling means 75 W from your legs. The 75% plan keeps a quarter in reserve, the share one measured pedelec left unused.
Hills, wind, stops, cold air and a heavier load all shorten those rides, and each review prices them row by row. At 20 mph on the throttle, the same model gives 26 miles on either folder, 27 on the LT7 and 31 on the XT8.
Budget three quarters of the steady figure. At 15 mph on the throttle with 180 lb aboard, the plan comes to 28 miles on the SF20H or the SX20 and 34 on the Zeal XT8.
Tell us how far you ride, how much you climb, what you and your load weigh, and how fast you like to go. We will run the trip for any of the six before you order and reply in miles at support@redtailebikes.com. The XT8 and the E-Cozy carry the largest packs of the six, 720 Wh each, and the XT8 is $1,399.
Order the XT8 for the milesWhich VTUVIA fits your height
Start with VTUVIA's own window, then check the stop. Each table below reads VTUVIA's published heights against the 6,068 soldiers in the US Army's 2012 anthropometric survey, women and men together.
| Model | VTUVIA's rider window | Inseam VTUVIA recommends | Step | Seat, floor to top |
|---|---|---|---|---|
| SX20 | 5'0" to 6'2" | 26 to 34 in | 13.8 in (15.4 on the size chart) | 30.7 to 41.7 in |
| E-Cozy | 5'1" to 6'3" | 30.5 to 39 in | 14.8 in | 27.2 to 37.0 in |
| SF20H | 5'3" to 6'2" | 28 to 34 in | 16 in | 29 to 34 in |
| CMB 8-Speed | 5'1" to 6'1" | 27 to 33 in | 16.9 in | 31.5 to 39.4 in |
| Zeal LT7 and XT8 | 5'3" to 6'2" | 28 to 34 in | 18.5 in | 35.4 in at its lowest |
From each VTUVIA product page's size guide or specification, read September 28, 2026; the SX20's second step figure is from VTUVIA's size chart.
Standing astride at a stop, every step here is low. At 5'3", 95 of every 100 riders in the survey clear the step by 10.2 inches or more on the Zeals, 11.8 on the CMB, 12.7 on the SF20H, 13.9 on the E-Cozy and 14.9 on the SX20.
Sitting on the saddle at its lowest is where the six differ. This table counts the riders of 100 at each height in the survey whose barefoot inseam reaches the lowest published seat, so both feet sit flat at a stop:
| Your height | SF20H, 29 in | SX20, 30.7 in | CMB 8-Speed, 31.5 in | Zeal LT7 and XT8, 35.4 in |
|---|---|---|---|---|
| 5'0" | 24 of 100 | 0 of 100 | 0 of 100 | 0 of 100 |
| 5'3" | 91 of 100 | 25 of 100 | 6 of 100 | 0 of 100 |
| 5'6" | 100 of 100 | 85 of 100 | 58 of 100 | 0 of 100 |
| 5'9" | 100 of 100 | 100 of 100 | 97 of 100 | 2 of 100 |
| 6'0" | 100 of 100 | 100 of 100 | 100 of 100 | 33 of 100 |
Survey bodies at each height, barefoot inseam against VTUVIA's lowest seat-to-floor figure, rounded to whole riders.
The E-Cozy's seat starts lowest of all, at 27.2 inches. There, 93 of every 100 riders at 5'0" reach the ground flat-footed, and at 5'3" and up every rider in the survey does.
From 5'6" up, the folders and the E-Cozy let most riders sit at a stop; the Zeals ask you to stand. At 5'6", 100 of every 100 riders sit flat-footed on the SF20H and 85 on the SX20, against 0 on either Zeal.
On the Zeals, sitting flat-footed is rare below 6'0", so a Zeal rider stops by sliding forward off the saddle to stand over the 18.5-inch step. The XT8 review sets the saddle height for every height from 5'1" to 6'4", and the LT7 review from 5'1" to 6'3".
Under 5'3"? VTUVIA sizes the SX20 from 5'0", over a 13.8-inch step on its product page. Email your height and inseam to support@redtailebikes.com and we will send back the saddle setting on any of the six before you order.
Get the low-step SX20The class question: 500 W or 750 W, and a trike
All six ship as Class 2: pedal assist and a thumb throttle to 20 mph. VTUVIA's class notes say each "comes out of the box" as a Class II machine, the E-Cozy as a "Class II electric trike". The motors differ: two are rated at 500 W, and four at 750 W.
Federal consumer-product law draws its line in 15 U.S.C. § 2085(b):
For the purpose of this section, the term "low-speed electric bicycle" means a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph.
California's Vehicle Code § 312.5(a) words its watt line differently: "a bicycle equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power".
| Model | Motor, as VTUVIA rates it | Federal "less than 750 watts" | California "does not exceed 750 watts" |
|---|---|---|---|
| Zeal LT7 | 500 W, 750 W peak | under it | meets it |
| CMB 8-Speed | 500 W mid-drive, 820 W peak | under it | meets it |
| SF20H, SX20 and Zeal XT8 | 750 W, 1,200 W peak | on the line, not under it | meets it |
| E-Cozy | 750 W, 1,200 W peak | on the line, not under it | meets it |
The two texts as read September 28, 2026, against VTUVIA's rated figures. Neither text says whether it means the rated or the peak figure; every peak here is 750 W or more.
What each of these counts as on your roads, and what that asks of you, is your state's call. Each state's own definition is in our 50-state e-bike law atlas, and California's, section by section, on our California e-bike law page. The federal definition above and the BLM's below both name three-wheeled machines; for how your state treats a trike like the E-Cozy, read its definition in the atlas.
Trails and federal land
Off the pavement, the land manager decides. On land the Bureau of Land Management runs, 43 CFR 8340.0-5(j) 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.)" in one of three classes.
Paragraph (a)(5) of the same section keeps an e-bike outside the off-road vehicle rules only where all three of its conditions hold. The trail allows "mechanized, non-motorized use", the motor is not "exclusively propelling the e-bike for an extended period of time", and the field office "has expressly determined" that e-bikes "should be treated the same as non-motorized bicycles".
Miss one and the machine is an off-road vehicle there. The penalty for breaking the off-road rules of subparts 8341 and 8343 is set by 43 CFR 8340.0-7: "a fine of not more than $1,000 or imprisonment for not longer than 12 months, or both". Holding the thumb throttle for miles without pedaling breaks the second condition on its own.
National Forests go further. The Forest Service's notice at 87 FR 41278 records directives for "managing all classes of e-bikes as motor vehicles", and 36 CFR 261.13 bars operating a motor vehicle "other than in accordance with those designations" on a district's motor vehicle use map. Each agency's rules are laid out in our public-land e-bike guide.
Check the watt line where you ride before you choose a motor. The LT7's and the CMB's 500 W sit under both 750 W lines; the other four are rated at 750 W, on the federal line and inside California's.
Tell us the state and the paths you ride, and we will answer the class question for any of the six in writing. The CMB 8-Speed is $1,399 with a 500 W rated mid-drive, under both 750 W lines above.

Two public records describe the company, and we set them side by side. VTUVIA's About page tells the brand's history in its own words. The USPTO's trademark register records who owns the VTUVIA name in the United States.
| What VTUVIA's About page says | What the US trademark register records |
|---|---|
| "VTUVIA was founded in Los Angeles, USA, in 2016." | Registration No. 7212929 for VTUVIA, issued November 7, 2023, for "Electric bicycles; Folding electric bicycles" |
| VTUVIA "introduced its first patented e-bike, the SN100, in 2018." | Owner: Changzhou Vtuvia Motor Technology Co., Ltd, a limited company in Wujin District, Changzhou, Jiangsu, China |
| VTUVIA "launched its official website in 2020." | Filed October 4, 2022, claiming first use in commerce on May 20, 2020 |
| VTUVIA says its name comes from the Latin word "VERTU" | An earlier VTUVIA application, filed March 5, 2018 by Vtuvia International Trade (Chang zhou) Co., Ltd., did not proceed to registration |
VTUVIA's About page read September 28, 2026; the USPTO's TSDR records for serial 97619483 and serial 87819607 read September 29, 2026. No assignment of either record is on file at the USPTO.
The register's owner name matches the brand's, and the register records no transfer of the mark. The About page describes the SN100 as the model that "quickly gained traction" after its 2018 launch.
VTUVIA in the federal recall register
No federal recall names VTUVIA. On September 28, 2026 we searched the Consumer Product Safety Commission's recall data for VTUVIA, Vtuvia and vtuviaebike by title, product name and manufacturer. Then we read all 623 of its bicycle, e-bike, battery and scooter recall records in full for the brand and the model names.
The title search for VTUVIA, run again on September 29, 2026, returns no record. The same search found the recalls brands are known to have, 1 for Ancheer, 54 for Specialized and 24 for Trek, which is what makes its silence on VTUVIA meaningful.
The name "Gemini" does appear in that corpus, 10 times, every one Cannondale's 2002–2003 Gemini bicycles, a different maker's product.

Our listings, read September 30, 2026; each fitting as our listing names it. Our SX20 battery listing notes that the 15 Ah version for the Reindeer and Zeal is sold out at VTUVIA.
The LT7, SF20H, SX20, XT8 and CMB pages each list a 54.6 V, 2 A charger. VTUVIA gives the charge time as "About 7 Hours" for the LT7, the folders and the E-Cozy and "About 7.5 Hours" for the CMB; our XT8 review plans on 7 hours for its 720 Wh.
The honest ledger
Six green flags from the record, then five rows on fit. Each flag links to the section of this page that holds its evidence, drawn from VTUVIA's product pages, the CPSC's recall data or our own store.
Green flags
- Nine of nine listings priced the same as VTUVIA's US store on September 30, 2026, with VTUVIA's higher regular price printed beside each.
- All six ship as Class 2 at 20 mph, and the LT7 and the CMB are rated at 500 W, under both 750 W lines.
- Two certification rows printed on VTUVIA's pages: UL 2271 and UL 2849 on the SF20H and the CMB 8-Speed.
- No federal recall names VTUVIA, against controls that find 1, 54 and 24 for three other brands.
- A step at or under 18.5 inches on every model, and 13.8 inches on the SX20.
- A trike rated for 450 lb, with reverse, a rear differential and a backrest.
Who should read something else first
Each row is about fit: who a VTUVIA is wrong for, and where to go instead.
| If you are | Why a VTUVIA may not fit | Where to go |
|---|---|---|
| Taller than your model's window | The six product pages end their windows between 6'1" and 6'3" | Send us your height and inseam and we will confirm the fit or name a taller frame we sell |
| Carrying more than 450 lb with you | The E-Cozy's 450 lb is the highest rating of the six | Email us the load and we will match a trike or cargo bike we sell to it |
| Riding paths that admit Class 1 bikes only | All six carry a thumb throttle | Our 50-state law atlas prints each state's class rules |
| After a motor rated over 750 W | The highest rating among the six is 750 W | The law atlas shows where your state draws its watt line, and we will name a model above it by email |
| Planning a second pack on the frame | None of the six carries two | Our Eunorau META275 2.0 review: a 720 Wh pack with room for a second |
Four checks before you order
Four readings settle a VTUVIA order before you pay: your inseam, your loaded weight, your state's e-bike definition and your commute in miles. Each reads against a table or page linked below, and if you send us the four, we answer them by email before you order.
- Measure your inseam and read your row in the fit tables, against the window VTUVIA prints for your model.
- Weigh yourself and what you carry together, and stay inside the model's total capacity: 300 lb on the CMB, 330 on the folders, 350 on the Zeals and 450 on the E-Cozy.
- Look up your state's e-bike definition in the law atlas, and the posted rules on each path or trail you use.
- Price your commute in miles with the range tables, keeping a quarter of the pack in reserve.
Three wheels, a backrest and 450 lb of capacity: the E-Cozy is $2,099 in Pearl White, the colorway VTUVIA had in stock on September 30, 2026. It ships free to the lower 48, or $189.45 a month for 12 months at 15% APR through Shop Pay.
Order the E-Cozy trikeFrequently asked questions
Is VTUVIA a good brand?
On the records we can check, VTUVIA's name is registered to its own company at the USPTO, no federal recall names it, and all nine of our listings matched VTUVIA's own US prices on September 29, 2026. The SF20H and the CMB 8-Speed print UL 2271 and UL 2849 on their specification tables (the ledger).
Where are VTUVIA bikes made?
VTUVIA's About page says the brand was founded in Los Angeles in 2016. The US trademark is registered to Changzhou Vtuvia Motor Technology Co., Ltd., at an industrial-zone address in Wujin District, Changzhou, China (who makes VTUVIA). For a given bike's assembly site, email us and we will ask VTUVIA in writing.
Which VTUVIA electric bike is best?
It depends on your frame and your load. For a folder that seats two, the SF20H; for the lowest step, the SX20; for a commute, the Zeal LT7 or XT8; for climbing on gears, the CMB 8-Speed; and for three wheels, the E-Cozy (the picks).
What warranty comes with a VTUVIA from Redtail?
Buy it from us and we are who you contact about a fault: send photos and your order number, and we open the claim and see it through. Faults covered by our refund policy include a bike that won't power on or charge, shows an error code, or has a faulty component; ask, and we will send the terms for your bike in writing before you order.
How do I reach VTUVIA customer service?
For a VTUVIA bought from us, write to support@redtailebikes.com with your order number, and we handle it with VTUVIA. VTUVIA's contact page lists a Customer Support team.
Is there a VTUVIA dealer near me?
VTUVIA publishes a dealer page. We ship every VTUVIA on this page free to any address in the contiguous United States, in 5–10 business days after 1–3 days of preparation (buying from us).
Where can I get a replacement VTUVIA battery?
Our shelf carries VTUVIA's 48 V packs by family: $499 for the SF20 family's 15 Ah and $599 for the SX20's 14 Ah. Send us the label on your pack and your model, and we will confirm the fit before you order (batteries and parts).
Where can I buy VTUVIA parts?
We list VTUVIA's chargers, keys, fenders, seatposts, baskets, racks and the cargo trailer, each with the fittings our listing names, in our VTUVIA parts collection.
What should I do if my VTUVIA battery is not charging?
Check that the charger is the one your model's page lists, then email us your order number, your model and what the display shows. Our refund policy covers a bike that "won't charge", and we open the claim.
Why is my VTUVIA e-bike beeping?
Note what the display shows while it beeps and send it to us with your model and order number. Our refund policy covers a bike that "shows an error code", and we coordinate the repair with VTUVIA.
How fast does a VTUVIA go?
All six ship as Class 2, with pedal assist and a thumb throttle to 20 mph, VTUVIA's class notes say (the class question).
How do I charge a VTUVIA, and how long does it take?
Use the charger your model's page lists: 54.6 V at 2 A on the LT7, SF20H, SX20, XT8 and CMB pages, and our $99 2A charger comes in each family's fitting (batteries and parts). VTUVIA gives "About 7 Hours" for the Zeal LT7, the SF20H, the SX20 and the E-Cozy, "About 7.5 Hours" for the CMB 8-Speed, and "About 6.5 Hours" for the Zeal XT8.
Is the VTUVIA E-Cozy a good trike for seniors?
VTUVIA writes that its 14.8-inch step makes it "easier to mount and dismount", and gives it a backrest, a reverse mode and a seat that starts at 27.2 inches, where 93 of every 100 riders at 5'0" reach the ground flat-footed. Its 450 lb capacity is the highest of the six (fit).
What is a mid-drive e-bike?
A mid-drive puts the motor at the pedals, so it drives the chain and works through the gears; a hub motor sits in a wheel. The CMB 8-Speed is the one VTUVIA mid-drive on our shelf, with 500 W and 175 N·m on VTUVIA's page, and our motor guide sets the two designs side by side.
What is a Class 2 electric bike?
California's § 312.5(a)(2) describes a class 2 e-bike as one with a motor that "may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour": a throttle bike that stops helping at 20 mph. All six VTUVIAs here ship as Class 2.
Can I finance a VTUVIA?
Yes. Shop Pay on each listing offers 15% APR plans of 3, 6 or 12 payments for these prices: $99.19 a month for 12 months on the LT7, up to $189.45 on the E-Cozy (buying from us).
The bottom line
VTUVIA gives us six machines we can ship today, from the $1,099 Zeal LT7 to the $2,099 E-Cozy, all Class 2 at 20 mph and all priced as VTUVIA prices them. On the public record, the VTUVIA name is registered in the US to its own company, and no federal recall names it.
Pick the frame first. Fold with the SF20H if you carry a passenger, or the SX20 if you stand 5'0" to about 5'9". Commute on a Zeal, climb on the CMB 8-Speed, or take three wheels on the E-Cozy.
For most daily riders, the Zeal XT8 is where to start: 720 Wh computed at 45 miles at 15 mph on the throttle for a 180 lb rider, turn signals fitted, $1,399, or $126.27 a month over 12.
Glacier White, $1,399, free delivery to the lower 48. Send us your height, inseam and commute first if you are unsure, and we will answer before you pay.
Start with the XT8, $1,399Limitations
Ten things this profile cannot settle, set out so you can weigh them.
- We sell these bikes. Weigh the fit column of the ledger as heavily as the green flags.
- This profile is specification-verified. Its figures come from VTUVIA's product pages, records and posts, the USPTO, the CPSC, our own store and published research, or arithmetic shown here.
- Range is computed for three models only. The SF20H, SX20 and Zeal XT8 figures come from each review's saved model; the other three carry VTUVIA's figures and our division of them.
- VTUVIA's posts print other figures for some models. For the Zeal LT7, posts give ranges from 30 to 80 miles, 63 N·m, a "48V 15Ah" pack, IPX6 and a "foldable frame", and windows of 5'1" to 6'3" and 5'5" to 6'1"; the LT7 review maps each range figure to a ride. For the Zeal XT8, a September 11, 2025 post prints 68 and 38 miles, and two posts print 5'1" to 6'3" and 5'4" to 6'4" windows. For the CMB, posts give an 818 W peak and up to 70 miles, several of them written about the 10-speed CMB Pro. This profile prints each product page's figure.
- The Zeal XT8's load has two figures. Its specification table prints 350 lb and its FAQ 400; this profile plans on 350.
- The fit tables use the US Army's ANSUR II bodies, 6,068 soldiers measured from 2010 to 2012, who are not the US public. Your own inseam decides your row.
- The SX20's lowest seat has three figures: 30.7 in on its product page, 31 in on its size chart and 31.4 in a 2024 post. The flat-foot counts use 30.7, the only figure given with a highest seat from the floor.
- The flat-foot counts set a barefoot inseam against the seat's top height. Shoes, the saddle's width and leaning the bike all change what you feel at a stop.
- Stock at VTUVIA was read on September 30, 2026. The SN100, Gemini and Reindeer 2.0 were sold out there that day, the E-Cozy in every colorway but Pearl White, and any model or colorway can come back or sell out.
- The recall search covers the CPSC's records only. A recall issued by another country's regulator would not appear in it.
Expiry conditions
Re-read this page if VTUVIA changes a price, a specification, a range figure, a size guide or a class note for any of the six, lists a sold-out model again, or publishes a new model. Re-read it as well if a recall names VTUVIA, if the VTUVIA registration changes owner at the USPTO, or if California amends § 312.5 or the BLM or the Forest Service changes its e-bike rules.
