Cover: the TST R002 in black, from TST's own product image, standing in a dark studio. Text: Who makes TST. What 32 mph means. TST GRP LLC, six e-bikes from $799. 6 e-bikes on TST's US store; pictured: R002.

TST's e-bikes as TST publishes them on October 16, 2026: who stands behind the brand, all six bikes and the GT63 at TST's own figures, what the 32 mph setting means under each state's definition, what TST's warranty and return terms say, and the six bikes we sell on the same footing.

Quick Answer — TST is the e-bike brand of TST GRP LLC, which says it was founded in California in 2017. On October 16, 2026 its TST Ebike store listed six e-bikes from $799 and a dirt bike. TST lists 32 mph for the R002, R7 and R9, and at 32 mph no state's or DC's e-bike definition takes in a throttle bike.

TST's own blog says its frames and components "are produced by specialized overseas factory partners," and three of its product pages print an SGS mark with the number 803623 (TST's "who makes" post, TST's R002 page). No CPSC recall, warning or news release names TST.

If you are shopping, six bikes we sell each sit at or under a TST model's motor and top speed, from $1,099, and every e-bike we sell ships free to the lower 48.

The short answer TST sells powerful bikes at low prices, and three things decide whether one is right for you: the speed you will ride it at, the warranty table you plan around, and whether TST ships to your address. Each has its own section below. To compare other makers first, start with our list of e-bike brands.

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

Every figure was read on October 16, 2026, at its source. For TST, that means its US store (each bike's page and store record, its comparison page, and its warranty, return, shipping, safety, FAQ, contact and test-ride pages), its own blog posts on manufacturing, top speed, motor ratings, certification and warranty, and its listings on Walmart and Amazon.

For the law, the federal record and the comparison, it means the CPSC's recall, warning and news registers (searched with control brands that carry known actions), each state's own code for the definitions quoted, and Ridstar's US store for the comparison.

The federal statute and regulations are quoted from their official texts, and watt-hours are computed from each maker's own voltage and amp-hour figures. In all, 67 sources were consulted and retrieved in full, each at its own address on the day, and are numbered below.

Redtail eBikes does not sell TST. We do sell the six bikes this page sets beside TST's, and on October 16 we read each one's price and stock at the company that builds it. Corrections go to support@redtailebikes.com.

Who makes TST eBikes, and is TST a good brand?

TST is the e-bike brand of TST GRP LLC, a company that says it was "Established in 2017 in California" and launched the TST brand in 2021, "focusing on high-power, cost-effective electric bikes." Its bikes are built by "specialized overseas factory partners," and design, quality control, warehousing and customer support are managed by its US operation (TST's About page, TST's "who makes" post).

You are probably here because a TST listing caught your eye: a moped-style bike for $799 on TST's own store, or the same name on Walmart or Amazon, with 1,500 W and 32 mph on the label.

Buy without checking and you can own a bike your state's e-bike definition leaves out, or a warranty that covers less than you expected. This page sets TST's own figures beside the law and beside six bikes we sell, so you can decide on the facts.

TST lists two California locations where you can see a bike or pick one up: 820 S Wanamaker Ave in Ontario, open Monday to Friday, 9 AM to 5 PM, and 1081 Grand Ave in Diamond Bar, open daily, 10 AM to 5 PM (TST's test-ride page). Its About page adds that the company sells in "over 10 countries" and has "more than 20 offline stores"; its test-ride page lists the two above.

TST ships to the continental United States only, and its shipping policy says "we DO NOT ship to Alaska and Hawaii" and "We do not sell to or ship to NYC as of 9/16/2023" (TST's shipping policy). On Walmart.com, a TST listing names "TS TST GRP LLC" as its seller, and on Amazon.com a TST listing links to the "TS TST GRP LLC Store" (a TST listing on Walmart, a TST listing on Amazon).

Where TST e-bikes are made

TST says its bikes "are manufactured by overseas factory partners to the brand's specifications, while design, quality control, warehousing, and customer support are managed by the US operation" (TST's "who makes" post). The post does not name a country, and neither do the product pages we read.

The practical question is the one TST's post itself raises: who answers when something fails. TST's answer is its support desk at support@tstebike.com and +1 (626) 878-4885 (TST's contact page), and its warranty and returns pages set the terms, which the warranty section lays out table by table.

TST's six e-bikes side by side

TST's US store listed six e-bikes on October 16, 2026: three moped-style bikes on 20 × 4 inch fat tires (R002, R7, R9), a 20-inch cargo bike (Carrier), a 27.5-inch step-through commuter (Surfer) and a folding fat-tire bike (Buddy Pro) (TST's catalog page). Prices ran from $799 to $1,199, each below a higher compare-at price TST prints beside it.

Model TST's price, October 16, 2026 (TST's compare-at) Motor, as TST prints it Top speed, TST's figure
R002 $799–$1,199 ($2,199–$2,399) 1,500 W peak 32 mph
R7 $799–$899 ($1,799–$2,099) 1,500 W peak 32 mph
R9 $859–$1,159 ($1,399–$1,699) 750 W rated, 1,500 W peak 32 mph
Carrier $1,099 ($1,899) 1,300 W peak 28 mph
Surfer $899–$959 ($1,877–$1,966) 1,000 W peak 23 mph on the throttle, 28 mph with pedal assist
Buddy Pro $899 ($1,999) 750 W rated, 1,000 W peak 28 mph

Battery, weight and fit, from the same pages:

Model Battery (Wh, computed) Weight · max load Rider height
R002 48 V 15 or 25 Ah (720 or 1,200) 71.87 lb · 450 lb 5'2"–6'4"
R7 48 V 15 Ah (720) 82.67 lb · 450 lb 5'2"–6'4"
R9 one or two 48 V 15 Ah packs (720 or 1,440) 87.74–96.56 lb · 450 lb 5'2"–6'4"
Carrier 48 V 15 Ah (720) 90.39 lb · 450 lb 5'1"–6'4"
Surfer 48 V 15 Ah (720) 71.32 lb · 400 lb 5'1"–6'4"
Buddy Pro 48 V 15 Ah (720) 71.87 lb · 450 lb 4'11"–6'4"

Rider heights are from TST's comparison page, and every other figure from each bike's own page (TST's comparison page). The R002 sells in two trims, Cruiser (65 Mile) from $799 and Adventure (100 Mile) from $1,099; the R9's higher price is the dual-battery version.

TST explains its motor numbers in its own words: "Most '1500W' e-bike motors, including TST's, are rated by peak output," and "sustained output is lower to protect the system from overheating" (TST's post on 1500W motors).

The R9 and Buddy Pro pages print a 750 W rating, and TST's top-speed guide says its moped-style bikes run "750W nominal (1500W peak) hub motors" (TST's top-speed guide). For the Carrier and the Surfer, every TST page we read gives the peak figure only.

The GT63 is an electric dirt bike

TST also sells the GT63, $1,199 with a $1,899 compare-at, and its own post on the bike says plainly what it is: "It is not a toy and not street-legal," and "the GT63 is a motorcycle-style machine with a throttle-only drivetrain" (TST's GT63 post, TST's GT63 page).

TST's two pages give the GT63 different figures: its product page prints "2600W Peak," "42 MPH" and a 48 V 23 Ah battery, and its comparison page prints 2200 W, 43 MPH and 48 V 22.5 Ah (TST's comparison page). TST's GT63 post describes it as "a 14-inch electric dirt bike for off-road use" (TST's GT63 post).

We sell no machine on its footing, and our guide to e-bike laws by state explains how a state classifies a machine outside its e-bike definition.

Matching a TST to a bike we sell

We do not sell TST. For each TST e-bike, the card below is a bike we do sell that stands on the same legal footing: a motor rated at 750 W or less, a top speed at or under the TST model's, and one motor.

On October 16, 2026, we read each one at the company that builds it: our price matches that maker's US store, the bike was in stock there, and the line that puts it on the TST model's footing is the maker's own.

Beside the R002

The R002 is TST's most-reviewed bike, with 439 reviews on its page: a moped-style frame with front and rear suspension, 20 × 4 inch tires, a 1,500 W peak motor and a 450 lb maximum load, from $799 in its Cruiser trim and $1,099 in its Adventure trim (TST's R002 page).

750 W rated · 20 × 4.0 in · 400 lb

Qiolor TIGER RL

$1,099 · maker's list $1,699

If the R002's retro moped shape is what drew you in, the TIGER RL gives you that look on a 750 W rating. Qiolor's TIGER RL page lists a 48 V motor rated at 750 W with a 1,200 W peak, a 48 V 13 Ah battery (624 Wh), CHAOYANG 20 × 4.0 inch fat tires, hydraulic disc brakes, a suspension fork and a 400 lb maximum load. Qiolor sets the default maximum speed at 20 mph.

You pay $1,099, the same as the R002 Adventure in Black. The RL is single-speed, weighs 87 lb and is recommended for riders from 5'1" to 5'9" (Qiolor's TIGER RL page), so it suits flat and rolling streets at a relaxed pace. If you want a rear shock as well, read the TIGER RE; if you are over 5'9", read the FLASH LITE 2.0 first.

Beside the R7

The R7 is TST's moped-style cargo bike: $799 in its Standard trim and $899 as the Cargo Edition, with a 1,500 W peak motor, hydraulic brakes, a 450 lb maximum load and 82.67 lb of bike (TST's R7 page).

52 V · 750 W · 440 lb

If you want the R7 for hauling on a moped-style bike, the FLASH LITE 2.0 does that job on a 750 W rating. Eunorau's FLASH LITE 2.0 page lists a 52 V 750 W rear hub motor with up to 92 N·m of torque, a 52 V 16 Ah battery (832 Wh) with optional second and third packs, 20 × 4 inch tires and a 440 lb total payload.

It costs $1,000 more than the R7 Cargo Edition, and Eunorau lists 82 to 92 lb of bike and riders from 5'2" to 6'4" (Eunorau's FLASH LITE 2.0 page). Our FLASH LITE 2.0 review computes its range and fit. Eunorau also builds it in Lunar Dust, and that color ships from us too: order the FLASH LITE 2.0 in Lunar Dust.

Beside the R9

The R9 is TST's long-range moped: $859 with one 48 V 15 Ah pack and $1,159 with two, 1,440 Wh in all, a motor TST rates at 750 W with 1,500 W peak, and up to 96.56 lb with both packs fitted (TST's R9 page).

750 W · 48 V 35 Ah · 400 lb

Qiolor TIGER RE

$1,399 · maker's list $2,099

If range is why the R9 is on your list, the TIGER RE carries more battery in one pack than the R9 carries in two. Qiolor's TIGER RE page lists a 750 W motor, a 48 V 35 Ah pack, which works out to 1,680 Wh against the dual R9's 1,440, a rear hydraulic shock, 20 × 4 inch fat tires and a 400 lb maximum load. Qiolor sets the default maximum speed at 20 mph.

You pay $240 more than the dual-battery R9. The RE weighs 98 lb and is recommended for riders from 5'1" to 5'9" (Qiolor's TIGER RE page), so it suits long, flat and rolling rides where you ride it from the garage. Our TIGER RE review works out what its 1,680 Wh pack has to deliver per mile at each range figure. Qiolor also paints it black: order the TIGER RE in Black.

Beside the Carrier

The Carrier is TST's family cargo bike: $1,099 with a 1,300 W peak motor, 28 mph, a 450 lb payload and passenger seating TST calls a "Kid-Safe Passenger Setup," at 90.39 lb (TST's Carrier page).

750 W · 440 lb payload

If the Carrier is your school-run bike, the MAX-CARGO 2.0 is a long-tail built for the same job on a 750 W rating. Eunorau's MAX-CARGO 2.0 page lists a 48 V 750 W hub motor that delivers "a continuous 750 watts," a 48 V 14 Ah battery (672 Wh) with an optional second pack, and a 440 lb total payload.

It costs $600 more than the Carrier, weighs 85 lb and is recommended for riders from 5'2" to 6'1" (Eunorau's MAX-CARGO 2.0 page). Our MAX-CARGO 2.0 review works through loads and range. For a frame that shows up better at dusk, order the MAX-CARGO 2.0 in White.

Beside the Surfer

The Surfer is TST's step-through commuter: $899 with a rack and fenders, $959 with a front basket, a 1,000 W peak motor, 27.5 × 2.25 inch tires and 71.32 lb of bike, at "23 mph in throttle mode and up to 28 mph in pedal-assist mode" (TST's Surfer page).

Torque sensor · 624 Wh · 62 lb

VTUVIA Zeal LT7

$1,099 · maker's list $1,299

If you want the Surfer's low step-through for a daily commute, the Zeal LT7 is a lighter bike for the same ride. VTUVIA's Zeal LT7 page lists a 48 V 500 W rear hub motor with 750 W peak, a torque sensor, a Shimano 7-speed drivetrain, a 48 V 13 Ah battery (624 Wh), a 350 lb payload and 62 lb with its rack and fenders.

You pay $200 more than the Surfer and carry about 9 lb less up the stairs. VTUVIA recommends it for riders from 5'3" to 6'2" (VTUVIA's Zeal LT7 page). Our Zeal LT7 review computes its range and fit.

Beside the Buddy Pro

The Buddy Pro is TST's folding fat-tire bike: $899, a motor TST says "is rated at 750 W and can briefly peak at 1000 W," 28 mph, 20 × 4 inch tires and a 450 lb maximum load (TST's Buddy Pro page).

750 W · folds · 330 lb

VTUVIA SX20 Antelope

$1,299 · maker's list $1,599

If you want a fat-tire bike that folds into a car or a closet, the SX20 does the Buddy Pro's job on the same 750 W rating.

VTUVIA's SX20 page lists a 48 V 750 W motor with 1,200 W peak, a 48 V 14 Ah LG battery (672 Wh), 20 × 4 inch tires, a 330 lb payload and 70 lb with its rack and fenders, and says it reaches "up to 20MPH with both throttle and pedal assist."

You pay $400 more than the Buddy Pro, and VTUVIA recommends it for riders from 5'0" to 6'2" (VTUVIA's SX20 page). Our SX20 review computes its range and fold. Other colors in stock at VTUVIA: Red, Cream White and Silvery.

Why buy one of these from us

The company behind your order is named in our terms of service, and a person answers for it: we typically respond to email within one business day, and every voicemail left through our contact page is returned.

The price on each card is the price its maker charges on its own US store, read on October 16, 2026, so buying from us costs you nothing extra. Every e-bike ships free within the contiguous United States: we dispatch within 1 to 3 business days of your order confirmation, and most arrive within 5 to 10 business days after dispatch (our shipping policy).

If your bike arrives damaged, note it with the carrier and email us photos within 48 hours of delivery so we can resolve it. If a component turns out faulty, it is covered under the maker's warranty and we coordinate the repair or replacement (our refund policy). Checkout takes Shop Pay, Apple Pay and Google Pay.

How we matched each bike

Four tests, in order. The bike is ours and in stock at its maker on the day, and its motor rating and published top speed sit at or under the TST model beside it, because a bigger motor or a faster setting can change what a bike is under a state's definition.

Then two checks on the bike itself: we charge what its maker charges in the US, and owners' public reports on that model, read on the open web, show no failure that repeats in a safety-related part.

Five of our six cost more than the TST beside them, by $200 to $1,000, and the TIGER RL costs the same as the R002's Adventure trim. What the difference buys is written on each card: a 750 W rating its maker prints, a maker-matched price, free shipping and our desk between you and the warranty.

We sell none of TST's bikes and all six of these, so read the cards as what they are: the bikes we would hand a TST shopper.

TST's 32 mph setting and the law

TST's moped-style bikes ship with their speed limited, and TST describes a setting that raises it. TST's R9 page offers to "Switch between Class 2/3 limits or unlock higher speeds (32 MPH) for off-road riding," and its top-speed post says the R002 starts "in stock Class 2 mode (20 MPH throttle limit)" (TST's R9 page, TST's top-speed post).

Your state's definition of an e-bike decides how the bike is treated, and at the 32 mph that TST's comparison page lists, no state and not DC has a definition that takes in a bike with a throttle. Read your state's rules before you buy, and know TST's own warranty words on changes before you change a setting.

At the federal level, the Consumer Product Safety Act covers a "low-speed electric bicycle" with "an electric motor of less than 750 watts (1 h.p.)" and a motor-only top speed, with a 170 lb rider aboard, of "less than 20 mph" (15 U.S.C. § 2085(b)). Congress wrote that line for the product safety rules a bike is made under; where a TST may be ridden is up to your state and your city.

TST's switchable speed raises a question the statutes quoted here do not settle: does a state class a bike by the setting it ships in, or by the fastest setting it can be switched to?

On paper, an R002 that can be switched to 32 mph is not the same machine as a bike capped at 20 mph for good, so before you buy, find out how your state treats a bike that can be switched, not just the setting yours leaves the box in.

What the three readings give

Applied to a 750 W rating, the figure TST prints for the R9 and the Buddy Pro and gives its moped-style bikes in its own posts, the definitions of the 50 states and DC split three ways, each read on October 16, 2026 (TST's R9 page, TST's top-speed guide).

  • At 20 mph with a throttle, the setting TST says the R002 starts in: 29 definitions take the bike in, 20 leave it out (the 19 states in the table below and New Jersey), and Alaska and Kentucky set no e-bike definition.
  • At 28 mph, read as a pedal-assist bike: 23 take it in. With the throttle working to 28 mph, none does.
  • At 32 mph, TST's listed top speed: none of the 51 takes it in, whatever the motor's rating; 49 leave it out, and Alaska and Kentucky set no definition.

TST's product pages for the R002 and R7 print the 1,500 W peak figure, and its posts give its moped-style bikes "750W nominal (1500W peak)" motors (TST's top-speed guide); for the Carrier and the Surfer, TST gives peak figures only.

None of the definitions quoted below says whether its 750 watts means rated or peak power, so if your state draws its line at 750 W, ask TST in writing for your model's rated figure before you buy.

New Jersey draws a separate line. Under P.L.2025, c.285, a bicycle with "an electric motor that is capable of propelling the bicycle in excess of 15 miles per hour through the use of a throttle" is a motorized bicycle, and TST lists 23 mph on the throttle for the Surfer and a 20 mph throttle limit as shipped for the R002.

What the counts say On a 750 W rating, 29 of the 51 definitions take in a throttle bike held to 20 mph, and none takes one in at TST's listed 32 mph. Set the bike to the speed your state's definition allows before you ride it on a public road.

The watt line in 19 states

In 19 states, the e-bike definition writes the line as "less than" or "fewer than" 750 watts, a line a motor rated at 750 W does not fall below. The table quotes each one and links its section. If you ride in one of these states, a bike rated under 750 W clears that watt line on any reading; among the bikes on this page, the VTUVIA Zeal LT7 is rated at 500 W.

What TST says about changes, water and age

TST's warranty page is direct about changes to the bike: "The warranty will be automatically expired if any unauthorized modification occurs," and its safety page adds that any attempt to modify the product, "including the motor and batteries, will void all warranties" (TST's warranty page, TST's safety page).

The same safety page sets TST's own floor for age: "You must be at least 16 years old to ride an e-bike capable of reaching speeds of 28 mph or higher" (TST's safety page). It describes the battery and electrics as "water-resistant, but not waterproof," and says "Avoid riding in the rain," and that the product "is not designed for jumping, rough terrain, sustained off-road use, or stunt riding of any kind."

TST's other pages answer the rain question differently. Its FAQ says "our ebikes are IP6 waterproof," and "You can ride our TST bikes in the rain or through a puddle," and its comparison page lists the R002, R7 and R9 as "Waterproof IPX5" and the Carrier as IPX4 (TST's FAQ, TST's comparison page).

The warranty page excludes damage from "Riding in heavy rain," so plan on the safety page's stricter words and ask TST in writing before you ride in the wet.

National parks

Each national park's superintendent "will designate the areas open to electric bicycles, or specific classes of electric bicycles," and outside areas open to public motor vehicles, riding a throttle bike like the R002 on its motor alone is limited: "using the electric motor exclusively to move an electric bicycle for an extended period of time without pedaling is prohibited" (36 CFR 4.30(i)).

A conviction under those rules is subject to "the criminal penalties provided under 18 U.S.C. 1865," which provides that a violator "shall be imprisoned not more than 6 months, fined under this title, or both" (36 CFR 1.3(a), 18 U.S.C. § 1865(a)). Before you load a TST for a trip to a national forest or park, read our guide to riding on public land.

How a 750 W rating reads in each state, and the bikes we sell that carry it.

See the 750 W e-bikes guide

Certification and the federal safety record

TST's product pages for the R002, R7 and Carrier print an "SGS Certified" mark with the line "c us 803623 Safety Certified," and TST's certification post says the documents behind its marks are available on request (TST's R002 page, TST's certification post). None of TST's seven product pages, read on October 16, 2026, names a UL standard.

TST's catalog page answers the question this way: "Some models feature UL-certified batteries for added safety. Please check the product page to see which bikes include UL-certified batteries" (TST's catalog page). One TST blog post refers to "TST EBike UL2849 certification," and TST's Walmart listing, sold under the name TS TST GRP LLC, puts "UL2849" in its title (TST's top-speed guide, the Walmart listing).

Before you buy, ask TST for the certificate that names your model and the standard it was tested to, and check the certificate number with the lab that issued it.

We searched all three of the Consumer Product Safety Commission's public registers on October 16, 2026: recalls (10,053 records), product safety warnings (375) and news releases (2,325). No recall, warning or news release names TST, TSTebike, TST GRP LLC or any TST model (CPSC recalls, CPSC warnings). Two records containing "TST" concern a 1996 halogen work light and 2008 egg containers, not bikes.

TST's warranty, returns and shipping, in TST's words

TST prints its warranty in more than one place, and the places differ. Plan on the shortest coverage TST states, and ask TST in writing which table applies to your order before you pay. The three statements, each read on October 16, 2026:

Part TST's warranty page TST's return page, "Warranty Policy (after 14 days)" TST's warranty post
Frame 2 years 1 year 2 years for "the frame, motor, battery, controller, and display"
Battery and electronics 1 year each (motor, battery, controller, charger, display) 6 months the same 2 years
Wear and small parts 6 months (brakes, throttle, crank, pedals, derailleur) 30 days (tires, tubes, brake pads) excluded as wear items

Sources: TST's warranty page, TST's return and refund page, TST's warranty post.

The warranty page excludes, among other causes, "Riding in heavy rain," "Submerging or washing the bike with high-pressure water," commercial or rental use, and damage from crashes, jumps and "aggressive or abusive riding" (TST's warranty page). It adds that whether a defect is covered "shall be in the sole discretion of TST," and that TST will not replace a part "without first seeing photos or video of the damaged components."

One clause matters if you ever dispute a charge: "If any ebike purchase becomes subject to a credit card charge back in any amount, and you are still in possession of the ebike, then this Limited Warranty shall be invalidated until the credit card charge back has been resolved" (TST's warranty page).

Returns and delivery

TST's return table allows a change-of-mind return of a new, unused bike within 14 days of delivery for a full refund, with the buyer paying return freight, and from 15 to 30 days with "a 20 % restocking fee" added (TST's return and refund page).

The same table says a bike that has been ridden is "Not eligible for return." Every return starts with TST's approval: the page says "Request authorisation first," and to pack the bike only "After receiving confirmation from TST via email" (TST's return and refund page).

TST quotes delivery at "3-5 working days" to the continental United States, and its FAQ says "a signature will be required upon delivery." Its shipping policy also offers "US local pickup," and asks that a damaged or wrong delivery be photographed and reported "within 3 days after the receipt" (TST's shipping policy, TST's FAQ).

TST's support line is +1 (626) 878-4885 and its email support@tstebike.com. Its contact page gives the hours as Monday to Friday, 7:00 AM to 7:00 PM PST, and its FAQ gives 7:00 AM to 4:00 PM PST, so call early in the day (TST's contact page).

TST vs Ridstar, side by side

Google's top related search for "tst ebike" is "ridstar" (Google Trends, "tst ebike", United States, 12 months to October 16, 2026), and the two brands sell similar fat-tire moped-style bikes. Set side by side on each maker's own figures, read October 16, 2026, the TST R002 and the Ridstar Q20 1500W differ most in the federal record.

TST R002 Ridstar Q20 1500W
Price on the maker's own US store $799–$1,199 $1,279, every variant sold out
Motor, as the maker prints it 1,500 W peak "1500W POWERFUL MOTOR"
Battery 48 V 15 or 25 Ah "48V/20AH"
Top speed, the maker's figures 32 mph "Max Speed Tested 28 MPH" in one place, "33MPH" in its own comparison chart
CPSC record no recall, warning or news release two product safety warnings, 26-337 and 26-584

Sources: TST's R002 page, Ridstar's Q20 1500W page.

On March 19, 2026, the CPSC warned consumers to stop using "Ridstar Q20 and Q20 Pro e-bikes" because "The e-bikes' batteries and wires can ignite, posing a fire hazard to consumers," and on June 25, 2026, it warned that on "Ridstar Q20 and Q20 Lite e-bikes" "The front wheel can detach without warning" (CPSC Warning 26-337, CPSC Warning 26-584).

If you own a Q20, read each warning in full and follow the Commission's instructions for your model. Our Ridstar brand profile sets out the brand's full public record, and our Q20 review covers the bike in detail.

The checklist before you buy a TST

Six checks, in the order that saves you money.

  1. Your state's definition. Read your state's rules and note whether its line is "less than" 750 W and what its top speed for a throttle is.
  2. The motor's rated figure. Ask TST in writing for your model's rated wattage; its product pages for the R002, R7, Carrier and Surfer list peak figures.
  3. The warranty table that applies. Ask TST which of its warranty tables covers your order, and keep the answer with your receipt.
  4. The certificate. Ask for the certificate behind the SGS mark, with the standard and the model on it.
  5. Delivery. Plan to sign for the bike, photograph any damage on arrival, and report it within 3 days.
  6. Your speed setting. Ride at the setting your state's definition allows, and read TST's warranty words before you change it.

Before you pay The two questions to put to TST in writing are the motor's rated figure and the warranty table for your order. Both answers decide what the bike is under your state's law and what you are covered for.

TST's price range: seven picks for five kinds of ride, each checked at its maker the same day.

Frequently asked questions

Is TST a good e-bike brand?

TST sells high-power bikes at low prices: six e-bikes from $799 to $1,199 on October 16, 2026, rated 4.64 to 4.82 out of 5 on the five TST e-bike pages with more than one review. Trustpilot shows no score for TST, citing "a breach of our guidelines." Whether one suits you depends on your state's definition and the warranty table TST confirms for your order.

Who makes TST e-bikes, and where are they made?

TST GRP LLC, which says it was established in California in 2017, sells TST e-bikes. TST's own post says the frames and components "are produced by specialized overseas factory partners," with design, quality control, warehousing and support handled in the United States. TST's pages do not name the country.

At the 32 mph TST's comparison page lists for the R002, R7 and R9, no state and not DC has an e-bike definition that takes in a bike with a throttle. At a 20 mph throttle setting on a 750 W rating, 29 do. Read your state's definition before you buy, and ask TST in writing for your model's rated wattage.

Is the TST e-bike Class 2?

TST's top-speed post says the R002 starts "in stock Class 2 mode (20 MPH throttle limit)," and its R9 page offers to "Switch between Class 2/3 limits or unlock higher speeds (32 MPH)." Whether a rider-switchable setting decides a bike's class is not settled in the statutes, so check how your state reads a bike that can be switched.

How fast is a TST e-bike?

TST lists 32 mph for the R002, R7 and R9, 28 mph for the Carrier and Buddy Pro, and 23 mph on the throttle with up to 28 mph on pedal assist for the Surfer (TST's Surfer page). TST's GT63 dirt bike lists 42 mph on its product page and 43 mph on TST's comparison page.

Are TST e-bikes UL certified?

Three of TST's product pages print an SGS mark with the line "c us 803623 Safety Certified," and none of its seven product pages names a UL standard. TST's catalog page says "Some models feature UL-certified batteries" and sends you to the product page, and its Walmart listing puts "UL2849" in its title. Ask TST for the certificate that names your model.

Are TST e-bikes waterproof?

TST's pages answer this more than one way. Its FAQ says "our ebikes are IP6 waterproof," its comparison page lists IPX5 for the R002, R7 and R9 and IPX4 for the Carrier, and its safety page calls the battery and electrical parts "water-resistant, but not waterproof" and says "Avoid riding in the rain." Its warranty page excludes damage from riding in heavy rain, so plan on the stricter statement and ask TST in writing.

What warranty does TST give?

TST's warranty page gives the frame 2 years and the motor, battery, controller, charger and display 1 year, while its return page lists 1 year for the frame and 6 months for battery and electronics. Plan on the shorter terms and ask TST in writing which table covers your order.

Can I remove the speed limiter on a TST?

TST's warranty page says "The warranty will be automatically expired if any unauthorized modification occurs," and at 32 mph no state and not DC has an e-bike definition that takes in a throttle bike. Ride at the setting your state's definition allows, and keep TST's warranty words in mind before you change it.

TST's own post on the GT63 says "It is not a toy and not street-legal," and describes it as "a motorcycle-style machine with a throttle-only drivetrain." TST lists it at 42 to 43 mph, so plan to ride it on private land or in areas open to off-road motor vehicles.

Where can I see a TST e-bike in person?

TST's test-ride page lists two California locations: 820 S Wanamaker Ave in Ontario, open Monday to Friday from 9 AM to 5 PM, and 1081 Grand Ave in Diamond Bar, open daily from 10 AM to 5 PM. TST's shipping policy also offers US local pickup.

Does TST sell on Amazon and Walmart?

Yes. On October 16, 2026, a TST listing on Walmart.com named "TS TST GRP LLC" as its seller, and a TST listing on Amazon.com linked to the "TS TST GRP LLC Store" (a TST listing on Walmart). Prices and descriptions there can differ from TST's own store, so compare the model, the battery and the warranty terms before you choose where to buy.

TST vs Ridstar: which is better?

On each maker's own figures, the TST R002 lists 32 mph and a 450 lb load from $799, and Ridstar's Q20 1500W page showed it sold out at $1,279. The CPSC has issued two warnings naming Ridstar Q20 models, and no recall, warning or news release names TST.

The bottom line

TST sells a lot of motor and battery for the money, from a California company with two locations you can visit, and its own pages say plainly that its 1,500 W figures are peaks, that its moped-style bikes ship speed-limited, and that a modification ends the warranty (TST's top-speed post, TST's post on 1500W motors, TST's warranty page).

Buy one if you have checked your state's definition and confirmed the warranty table in writing.

If you would rather start from a bike whose 750 W rating its maker prints, at its maker's own price, the bike we set beside TST's most-reviewed R002 is the Qiolor TIGER RL. It ships free to the lower 48, and if a component is faulty, we coordinate the warranty repair or replacement with Qiolor.

Or take your time: every card above links its maker's own page, and our desk answers questions at support@redtailebikes.com.

Limitations

These are the limits of this page: where we stand in relation to the brands named, where each figure came from, and what the method can and cannot show. You can hold us to each one.

  1. Interest: Redtail eBikes sells none of TST's bikes and sells all six alternatives named on this page. Each alternative was approved for this page by the store's owner and matched to a TST model by the stated footing rule: motor rating and published top speed at or under the TST model's, one motor.
  2. The footing rule is ours. It keeps each alternative on a like-for-like basis; it is not a legal test and does not establish how any state classifies any bike.

  3. Data: Every TST price, specification, rating and term was read on October 16, 2026, on TST's US store, its pages and its blog, and each can change. TST is the only publisher of its own figures and terms, so those rows rest on one publisher.

  4. TST's own pages disagree in five places, and this page prints both statements each time: the warranty (three tables), the rain question (its FAQ, its comparison page and its safety page), support hours (its contact page and its FAQ), the GT63's motor, speed and battery (its product page and its comparison page), and the R9's motor, which its specification table and FAQ call a rear hub motor and one feature block on the same page calls a "Mid-Drive Motor."
  5. TST's product pages for the R002, R7, Carrier and Surfer print peak motor figures. The 750 W rating for the moped-style bikes is from TST's own posts, and for the Carrier and the Surfer, none of the TST pages read that day (product pages, store record, catalog page, FAQ and blog) gives a rated figure.
  6. The owner ratings are the figures each platform printed that day: TST's own pages carry theirs as review data inside each product page, and a marketplace rating is that platform's figure for that listing. Whether a marketplace listing's bike is the same build as the same-named model on TST's store was not established.
  7. Trustpilot's notice does not say what the breach was, and this page prints the notice only.
  8. California's business registry refused our automated lookup on October 16, 2026, so the company's registration record is not printed; the founding year and place are TST's own statements.
  9. The definitions of Alabama, Illinois, Mississippi and Ohio and New Jersey's P.L.2025, c.285 were read on October 16, 2026 from a reader-proxy copy of each publisher's page, because the publisher's server did not serve the text to us that day; the clause quoted was matched in that copy.

  10. Method: The three state readings apply each definition's words to TST's published figures (a 750 W rating at 20, 28 or 32 mph, with or without a throttle). They read the statutes' text, not local ordinances, agency practice or case law, and Alaska and Kentucky set no statutory e-bike definition.

  11. The federal record covers the CPSC's recall, warning and news-release registers as listed on October 16, 2026 (10,053, 375 and 2,325 records), searched by brand, company and model name alongside control brands with known actions. It does not cover reports the Commission has not published.

Expiry conditions

  • TST's lineup, prices and terms, read October 16, 2026. They are re-read before this page is next updated.
  • TST's warranty statements. A new version of TST's warranty page, return page or warranty post changes the warranty table.
  • The CPSC registers. A recall, warning or news release naming TST or a TST model changes the safety section.
  • Ridstar's Q20. A Ridstar restock, or a CPSC update to Warning 26-337 or 26-584, changes the comparison.
  • State definitions. A 2027 session that rewrites a definition's watt line, speed limits or throttle rule changes the state counts and the table.
  • The six alternatives. A price, stock or specification change at any of the six makers changes its card.
