VIVI Electric Bikes Buying Guide: Commuter, Folding, Fat-Tire and Cargo Models

What this guide covers

This guide explains the current VIVI e-bike lineup as VIVI presents it on its own product pages, all read on 2026-10-07. It covers six models across VIVI's catalog - a cruiser-commuter, a folding mountain bike, a folding fat-tire commuter, a long-range fat-tire bike, a torque-sensor fat-tire model and a cargo trike - plus the recall notice you should read before anything else, the terms VIVI's spec sheets use, and what to check before you order.

Nothing here is a hands-on test. JellyMark has not ridden these bikes, so no sentence below reports how one of them performed. Every figure is what VIVI publishes, and where VIVI's own pages disagree, this guide says so.

Check the battery label first: a current VIVI recall

Before any model recommendation, the recall. VIVI is conducting a recall in cooperation with the U.S. Consumer Product Safety Commission, CPSC recall number 25-391, announced July 17, 2025. It covers certain 36-volt lithium-ion batteries shipped with specific VIVI e-bike models. The CPSC states that about 24,000 units are affected, that VIVI is aware of 14 reports of batteries overheating including three reports of fires, and that no injuries have been reported.

The recall covers specific battery model numbers, not every VIVI product. The affected e-bike model numbers in the CPSC table are C26, MT20, Z3, M026SH, H6, H7, MT26H, 26LGB, M026TGB, MT26G, FM20, F20, S3, Z1 and Z2 - fifteen in all. Each was sold with one or more affected battery model numbers; the full battery-model table is on the CPSC press release and on VIVI's recall page.

How to check your own bike: find the e-bike model number on the frame and the battery model number on the battery casing (printed on the top or bottom of the casing, per VIVI), and compare both against the tables on the CPSC press release and VIVI's recall page. Do not read a bike family name and assume it is affected or safe - the recall keys on the battery model, and the same family name can cover very different battery packs.

If your battery matches: the CPSC remedy is to stop using an e-bike with a recalled battery immediately and contact VIVI for a free replacement battery and charger. VIVI's replacement process has two steps and missing either can deny the swap: first get a confirmation from VIVI that your battery is under the recall, then provide proof that the recalled battery was disposed of at a household hazardous waste collection center. Contact VIVI toll-free at 800-375-6103, or start from the recall notice below.

What VIVI currently sells

VIVI groups its catalog as electric mountain, commuter, fat-tire, folding, cruiser, city and cargo e-bikes, plus accessories, parts and batteries. This guide covers six current models chosen so each fills a different job: a step-through cruiser-commuter (C26UL), a folding full-suspension mountain bike (M026TGBUL), a folding 3.0-inch fat-tire commuter (Gopina), a long-range fat-tire bike (F26FUL), an all-terrain torque-sensor fat-tire model (ACE01 Pro) and a folding cargo trike (T01). The wider catalog sits outside this guide - other city and cruiser frames, accessories and replacement parts are not compared here.

Read "listed as available" precisely: VIVI edits its pages, stock moves, and each storefront serves its own region. Everything above was observed on viviebikes.com on 2026-10-07.

Which shape is the job?

Before comparing specs, settle the shape. A daily commute on pavement with an easy step-over is the C26UL cruiser. A ride on rough trails that still needs to fold is the M026TGBUL folding mountain frame. A foldable commuter on wider tires for mixed surfaces is the Gopina. A long range per charge on mostly paved roads is the F26FUL. The most all-terrain hardware among the six covered here, with torque-sensing assist, is the ACE01 Pro. Carrying cargo and wanting a stable trike that parks small is the T01.

Weight matters to anyone who lifts a bike. The shop weight figures VIVI lists range from about 29 kg (roughly 64 lb) for the folding mountain bike to about 43 kg (roughly 95 lb) for the ACE01 Pro. A folding frame is only convenient up to the point you can lift it.

Battery, motor and range terms

Three spec patterns run through every VIVI page, and each needs translating. Motor wattage is stated as a peak figure: VIVI lists "1000W peak" motors on several models and a 750 W nominal motor with 1500 W peak on the ACE01 Pro. A peak figure is the maximum the motor can draw briefly, not a constant output, and VIVI does not publish a continuous rating on the surfaces checked. Battery capacity multiplies voltage by amp-hours: 48V 7.8Ah is 374.4 Wh, 48V 12.8Ah is 614 Wh, 48V 15Ah is 720 Wh, 48V 18Ah is 864 Wh and 48V 10.4Ah is 499.2 Wh, and VIVI prints those watt-hour figures on the same pages. The watt-hour figure is the one that scales with range.

Range is a claim, never a measurement. Most VIVI range figures are phrased "up to": "up to 60 miles (pedal assist)", "up to 40-50 miles", "up to 40-55 miles (with pedal assist)". Two models quote flat mode ranges instead - the C26UL's "22-25 miles (electric bike mode) to 44-50 miles (assist mode)" and the M026TGBUL's "44-50 miles in assisted mode / 22-25 miles with full power" - and nothing on those descriptions softens them into an upper bound. A range claim, flat or hedged, depends on rider weight, terrain, assist level and temperature, so treat the number as the maker's figure rather than a promise. Where a quick-spec block prints a single round "50 miles" (as it does on the C26UL, M026TGBUL and Gopina pages), the description on the same page gives the range breakdown - the description is the more careful figure.

Six models worth knowing

Each model below is a representative choice by use case from VIVI's current lineup. It is not a ranking; the right pick is the one that matches your job.

VIVI C26UL: the step-through cruiser-commuter

The C26UL is the entry cruiser of the covered lineup: a step-through frame with 26-inch puncture-resistant tires, a "1000W peak" brushless gear motor, a removable 48V 7.8Ah battery that VIVI lists as 374.4 Wh, and a Shimano 7-speed drivetrain. VIVI states top speed at 22 mph and range as "22-25 miles (electric bike mode) to 44-50 miles (assist mode)". Front and rear suspension is listed, and the quick-spec block lists a max capacity of 330 lb. VIVI's product title states the C26UL is "SGS Certified to UL2849" - that is the maker's statement, reproduced here as theirs. VIVI's shop weight for the C26UL is about 32.7 kg (roughly 72 lb).

VIVI M026TGBUL: the folding full-suspension mountain bike

The M026TGBUL is a folding full-suspension e-mountain bike with a "1000W peak" gear motor, a removable 48V 7.8Ah 374.4 Wh battery, Shimano 21-speed gearing and a rear spring shock. VIVI's description states the bike can reach 21.7 miles per hour; the same page's quick-spec block prints 22 MPH. Both are VIVI's own numbers on the same page, and this guide repeats the description's explicit figure rather than reconcile them. Range is listed as "44-50 miles in assisted mode / 22-25 miles with full power". Front and rear mechanical disc brakes, max capacity 330 lb, and VIVI's variant title carries the SGS-certified-to-UL2849 wording. At about 29 kg (roughly 64 lb), it is the lightest fold among the covered models.

VIVI Gopina: the folding 3.0-inch fat-tire commuter

The Gopina is a folding step-through commuter on 3.0-inch fat tires with a 700 W peak rear hub motor, a 48V 7.8Ah 374.4 Wh battery, dual disc brakes and a lockable front fork. VIVI lists BMS protection and IP65 waterproofing on the electrical components. Speed is listed at 21.7 mph and range as "up to 40-50 miles on a full charge" (also stated as a cruising range of 20-50 miles). Max capacity 330 lb; weight about 32.7 kg (roughly 72 lb). VIVI's product title states "SGS Certified to UL2849" - and only that: the page checked does not print a UL 2271 claim for the Gopina, so neither does this guide.

VIVI F26FUL: the long-range fat-tire bike

The F26FUL is a long-range 26x4.0 fat-tire bike with a "1000W peak" motor and 75 Nm of torque. The battery is configurable rather than one fixed pack: the page lists an "optional 614Wh & 864Wh removable lithium battery", and the variant selectors name the base F26FUL at 48V 12.8Ah (614 Wh) and the F26FUL Pro at 48V 18Ah (864 Wh). The description's "48V 18Ah battery" line refers to the Pro option, so match the Wh figure on the variant you pick rather than assume one battery ships with every bike. VIVI lists top speed at 25 mph and range as "up to 60 miles (pedal assist)". Mechanical disc brakes with 160 mm rotors, a 12-magnet cadence sensor, Shimano 7-speed and a 330 lb max capacity. VIVI's title states SGS certified to UL2849 and UL2271. Weight about 35.4 kg (roughly 78 lb).

VIVI ACE01 Pro: the torque-sensor fat-tire all-terrain

The ACE01 Pro is VIVI's all-terrain fat-tire model with the brand's upgraded torque sensor, app control, a 750 W rear hub motor with 1500 W peak and 90 Nm of torque, a 48V 15Ah 720 Wh removable semi-integrated battery, hydraulic disc brakes with 180 mm rotors, a suspension fork with lockout and adjustment at 100 mm travel, and Shimano 7-speed gearing. VIVI lists top speed at 25 mph and range as "up to 60 miles (pedal assist)". The torque sensor is the differentiator: a cadence sensor only knows the pedals are turning, while a torque sensor measures how hard you push, which most riders read as a more natural assist. VIVI's page states the ACE01 Pro passed both UL 2849 and UL 2271 safety certifications - the maker's claim, quoted rather than asserted. At about 43 kg (roughly 95 lb) it is the heaviest of the covered models.

VIVI T01: the folding cargo trike

The T01 is VIVI's folding cargo trike with two rear wheels, a 6061 aluminum frame, a "1000W peak" rear drive motor with 75 Nm of torque, a 48V 10.4Ah 499.2 Wh AMAK-series removable battery, mechanical disc brakes with a parking function, a rear differential, walking assist and front and rear baskets. VIVI lists a top speed of 15.5 mph - the slowest of the covered models, which is expected and desirable for a cargo trike - and range as "up to 40-55 miles (with pedal assist)". Max capacity is 285 lb, the lowest of the covered models, and weight about 38.1 kg (roughly 84 lb). VIVI's page states the T01 is SGS certified to UL2849 and UL2271, and lists the bike as 95% pre-assembled.

Current generation versus older model names

Two covered models - the C26UL and the M026TGBUL - carry a suffix that resembles a certification, and the older VIVI models C26 and M026TGB appear on the CPSC recall table. The naming is worth understanding precisely.

The recall keys on the battery, not the frame. The current C26UL and M026TGBUL are not in the CPSC affected-model list - only C26 and M026TGB are - and that fact alone proves nothing about safety, because the recall keys on the battery, not the bike. A 36-volt battery can be bought, moved between frames or matched to a different model, and the recall table lists a battery as affected when it was sold with a specific bike. Nothing here claims the C26UL or M026TGBUL is or is not recalled: the only safe check is the battery-label comparison described above. If a current-model owner's battery label matches a recalled battery model number, the recall applies to that battery regardless of the frame it is installed in.

The suffix is part of VIVI's current model name, and it should not be treated as evidence of certification or of recall status on its own. For certification, use the wording on the exact current product page: the C26UL page states "SGS Certified to UL2849" and the M026TGBUL variant title carries the same wording. For the recall, the battery label controls: compare the battery model on the casing against the tables on the CPSC press release and VIVI's recall page. Do not infer certification from a suffix and do not infer recall status from a family name or suffix.

Warranty, support and parts

VIVI publishes its return and warranty terms on the store, read here on 2026-10-07. Returns run 30 days from receipt: email service@viviebike.com first, the item unused and in original packaging with proof of purchase, and returns approved by VIVI. The customer pays return shipping on consumer-responsible returns, e-bikes registered in the buyer's name cannot be returned, and no restocking fee is listed.

The main warranty is stated as a "1 Year Free Warranty Guarantee" from the date of purchase for non-human damage, excluding some named components. The component table lists 12 months on frame, fork, battery, motor, controller and charger; 6 months on handlebar, meter, front hub, wheel hub and rear shock; and 3 months on tires, brakes, disc and sensor among others. After the first year, VIVI states lifetime after-sales support with the customer bearing the cost and shipping of replacement components. The warranty is under the initial purchaser; pre-owned bikes are only covered if the original warranty is unexpired and VIVI can match the original owner's name, email and order number. Coverage applies to bikes from authorized retailers or viviebikes.com and is void on abuse, neglect, modification or accident.

These are VIVI's published terms, not advice about a claim. The policy page is the authoritative text and can change. Warranty and return links are kept free of affiliate tracking.

What to check before you order

• ▸Check the battery label against the recall tables before any model: the frame number, the battery model on the casing, and the CPSC and VIVI recall pages.
• ▸Confirm the current spec sheet on the store that serves you. VIVI edits its pages without notice, and this guide's figures were observed on 2026-10-07.
• ▸Read the conflicts VIVI's own pages contain: the M026TGBUL speed is 21.7 mph in the description and 22 MPH in the quick-spec, and the F26FUL battery is configurable (614 Wh base, 864 Wh Pro) so the variant you pick must match the Wh figure.
• ▸Weigh the tradeoff for a fat-tire or trike model: the heavier all-terrain and trike models (about 84 to 95 lb) are harder to lift than the folding commuters (about 64 to 72 lb).
• ▸Check local law before ordering: e-bike class, throttle, top-speed and helmet rules vary by state and municipality, and VIVI's published speed figures are the maker's claim, not a guarantee of legality where you ride. This guide is not legal advice.
• ▸Confirm the storefront: the recall and warranty terms apply to bikes from authorized retailers or viviebikes.com, and a listing elsewhere may carry different terms.

Frequently asked questions

Are all VIVI bikes recalled? No. The recall covers specific 36-volt lithium-ion battery model numbers shipped with specific bike models (CPSC 25-391). The affected bike model numbers are C26, MT20, Z3, M026SH, H6, H7, MT26H, 26LGB, M026TGB, MT26G, FM20, F20, S3, Z1 and Z2, and the affected battery models are listed per bike on the CPSC press release and VIVI's recall page. Check the battery label, not the family name.

Is the current C26UL or M026TGBUL covered by the recall? The recall keys on the battery, not the frame. Neither current model appears in the affected-model list, and that fact alone tells you nothing about safety on its own - the only safe answer is the label comparison: check the battery model on the casing against the recall table. Do not treat the suffix as proof either way.

How do I get a replacement battery under the recall? VIVI's two-step process: first get confirmation from VIVI that your battery is under the recall, then provide proof that the recalled battery was disposed of at a household hazardous waste collection center. VIVI then ships a free replacement battery and charger. Contact 800-375-6103 or start at viviebikes.com/pages/recall.

What does "up to 60 miles" mean on VIVI's range claim? It is an upper bound in pedal-assist mode under favorable conditions. Real range depends on rider weight, terrain, assist level and temperature, and VIVI's own pages state different range breakdowns for different modes. Treat it as the maker's claim, not a measurement.

Is the Gopina UL-certified? VIVI's Gopina product title states it is "SGS Certified to UL2849". VIVI does not print a UL 2271 claim for the Gopina on the page checked, so this guide reproduces exactly what VIVI states for that model.

Does the warranty transfer if I buy secondhand? Only under conditions: the original 1-year warranty must be unexpired, and VIVI must be able to match the original owner's name, email and order number. Otherwise the warranty is under the initial purchaser.

The bottom line

VIVI's current lineup covers commuting, folding, fat-tire, mountain and cargo-trike jobs, and the six models above are representative picks from that lineup, each sourced from what VIVI publishes. Keep the order of operations straight: check the battery label against the recall tables first, match any configurable battery to the Wh figure on the variant you pick, treat every range figure as a manufacturer claim, and confirm the spec sheet on the store that serves you before you order.
