GLOBALKEEP K6-G

GLOBALKEEP sells this frame under more than one name, and mixing them up means buying a different bike. On Amazon the K6-G is the 20" K6-G-ADVANCED BASIC option in a three-bike listing family. The item details on the same page give the model as K6-L, and GLOBALKEEP's own K6 user manual labels the frame and handlebar "K6-L/K6-G", so treat the two names as one bike.

The other two options in that family are not this bike. The K6-MINI is a smaller, cheaper machine on 16 x 3.0 tires and spoked wheels, sized for riders from 5 feet to 5 feet 8 inches. It shares the motor and battery figures but not the frame, so its ratings and sales badge tell you nothing about the K6-G. The K6-U, listed as "K6-PRO-GAME", is a different 20-inch model sold as a bundle with a pump and a bag at a higher price.

One more name to recognise: GLOBALKEEP co-markets with Hikeep, and the bike pictured in GLOBALKEEP's own K6 manual wears HIKEEP lettering on the frame, as does the bike in every photo on this Amazon listing (checked October 31, 2026). If that name turns up on your bike or its paperwork, it is the same family.

A moped-style e-bike is built to look like something that needs a license plate. That look is what draws attention from police, park rangers and building managers. Whether it is legally a bicycle or a motor vehicle comes down to three facts: working pedals, rated motor power and top speed on the motor. The K6-G has pedals and a seven-speed drivetrain, and its listing states 750 W rated and 20 mph on the throttle. That is the Class 2 definition, a throttle bike whose motor stops helping at 20 mph.

In practice Class 2 buys you two things. Most states treat it as a bicycle, so there is no license, registration or insurance to arrange. And Class 2 is usually allowed wherever Class 1 is, including many bike paths, where Class 3 is often kept off by default. Two states are exceptions you should know before ordering. New Jersey now requires a license and MVC registration for every e-bike, plus insurance and a DOT helmet for throttle bikes (New Jersey rules). Hawaii requires a one-time registration (Hawaii rules). Check the rest on our state law hub, or put this bike and your state into the ride check tool for road, bike lane, path and sidewalk rules in one place.

The catch is in the listing's own FAQ: "Ships as a Class 2 e-bike with a 20 MPH factory limit to meet U.S. federal laws for street use. For private road use, settings can be adjusted via the display to reach its full potential." GLOBALKEEP's K6 manual gives the family's maximum speed as 30 mph, the listing's own speed graphic reads 20-28 MPH, and GLOBALKEEP's product page for the K6 says 28+ MPH. At 30 mph with a throttle the bike fits no US e-bike class, and moped or motor vehicle rules can apply to it. Our advice is the boring one: leave the 20 mph setting alone on any public road, lane or path. The moped vs e-bike guide explains where that line sits and what changes when you cross it, and the class explainer covers the three classes in more depth.

The title leads with 1500W Peak. The first bullet adds the figure that matters: "1500W peak output (750W Rated)". Peak is what the motor can deliver in short bursts, on a hill start or a hard launch. Rated, also called nominal or continuous, is what it is designed to sustain, and it is the number the law is written around: the federal definition describes a motor of less than 750 W, and the state class laws modelled on it generally use 750 W as the ceiling. A listing that gives only a peak figure leaves you unable to show a bike is inside that limit. This one gives a rated figure that sits on the line, which is where most legal Class 2 bikes in this format sit. We record 750 W as the motor rating on this page, not 1500.

GLOBALKEEP's K6 manual lists the family's motor as "500W/750W/1000W/1500W/2000W", because one manual covers several configurations. The Amazon listing is the only document that ties a figure to this ASIN, and it says 750 W rated. If the label on the hub or controller of the bike you receive says something different, that label is what an officer would read.

The title says "48V 15.6Ah UL2849 Battery", and the fourth bullet says the battery "is fully UL 2849, UN38.3, and 16 CFR Part 1512 certified". Those are not three battery standards. UL 2849 covers the complete electrical system of an e-bike, meaning the motor, controller, battery and charger together; the standard for the battery pack alone is UL 2271. UN 38.3 is the transport test any lithium battery must pass to be shipped. 16 CFR Part 1512 is the CPSC's set of mechanical requirements for bicycles and does not test batteries at all. Further down, the listing's FAQ calls the battery "UL 2271/2849 compliant", and compliant is a weaker word than certified. GLOBALKEEP's own website says "In accordance with UL2849".

None of that proves the bike is uncertified. It does mean the listing names no testing lab and no certificate, and we could not find one. If you need UL 2849 for a reason someone will check, such as New York City's sales rule or a building that bans uncertified e-bike batteries indoors, ask GLOBALKEEP for the certificate that names the K6-G or K6-L before you buy.

48 V x 15.6 Ah = 748.8 Wh, call it 749 Wh. The listing claims "up to 90-110 KM" with pedal assist, which is 56 to 68 miles. GLOBALKEEP's listing for the K6-U, which quotes the same 48 V 15.6 Ah pack, puts it at 42 miles on the throttle and 68 with pedal assist. Run the division:

• 749 Wh / 68 miles = 11.0 Wh per mile
• 749 Wh / 56 miles = 13.4 Wh per mile
• 749 Wh / 42 miles = 17.8 Wh per mile on the throttle alone

A heavy fat-tire bike near 20 mph typically uses 20 to 30 Wh per mile: more on the throttle with a heavy rider, less when you pedal in a low assist level on flat ground. That gives:

• 749 Wh / 30 Wh per mile = 25 miles
• 749 Wh / 20 Wh per mile = 37 miles

So the 68-mile figure fails the arithmetic for a bike of this weight, and 56 is a best case at the lowest assist level. We plan on about 30 miles of mixed riding. The listing states 800 to 1,000 charge cycles before the pack falls to 80% of its capacity, an IP65 rating, and a key lock that lets you take the battery indoors to charge.

At $499.99 the hardware list is complete for the format, with the usual budget compromises:

• Wheels and tires. 20 x 4.0 fat tires on one-piece cast wheels. The listing's "integrated" and "solid" wheels describe the rims, not the tires. Cast wheels have no spokes to tension or break, but a bent one means replacing the whole wheel.
• Suspension. A front suspension fork plus a "mid-chassis central shock absorber". Amazon's spec table calls that "Dual", but the listing also describes the rear frame as staying "hardtail stiff", which suggests the central shock cushions the rider rather than letting the rear wheel move on a swingarm. If true rear suspension matters to you, the DEEPOWER QS7 at $679 is the closer match.
• Brakes. Dual mechanical disc brakes with levers that cut the motor. Adequate at 20 mph, and one more reason to keep the limit where it ships.
• Drivetrain and modes. A Shimano seven-speed and three modes: throttle only, five levels of pedal assist, and no assist.
• Lights and extras. LED head and tail lights, plus turn signals and a horn on the handlebar switch per the manual, and a top-tube storage bag.
• Weight and fit. The listing states no weight. GLOBALKEEP's K6 manual gives 73 lb for the family, so plan around that and do not plan on carrying it up stairs. The load limit is 330 lb, and the listing suits riders from 5 feet 5 inches to 6 feet 2 inches (its FAQ says from 5 feet 4 inches).
• Assembly. About 90% pre-assembled; you fit the front wheel, handlebar, pedals and lights.

This is the part that holds the score down. When we checked the listing on October 31, 2026, the K6-G showed 4.5 stars from 4 ratings. The 4.2 stars from 9 ratings and the "100+ bought in past month" badge that appear beside GLOBALKEEP in Amazon search belong to the 16-inch K6-MINI, so do not read them as this bike's record. The listing family ranked #9 in Electric Fat Bikes that day, a rank Amazon reports for all three sizes together.

Four ratings tell you almost nothing about how the battery, controller or after-sales support hold up after a winter. We found no independent review of the K6-G, and we have not ridden it; every figure on this page is the Amazon listing, GLOBALKEEP's own K6 user manual, or our arithmetic on them.

Support is the other unknown. The listing gives a 1-year warranty. GLOBALKEEP's own warranty policy, effective February 13, 2026, says its store warranty applies only to bikes bought on globalkeepebike.com, and that bikes bought through Amazon and other channels "are subject to the warranty policies of those respective sellers". For an Amazon purchase you are relying on Amazon's return window and the seller's one-year promise. GLOBALKEEP lists email and phone support and a US address in Ontario, California, and the listing promises "localized US warehouse support" and replacement parts such as batteries and displays from its support team. That is better than nothing, and it is not a track record.

At this price the K6-G's edge is paperwork, not hardware. The FLIWIN Fat 20 at $498 has a bigger 960 Wh battery but states only a 2000 W peak motor and advertises unlocking to 34 mph. The Pescroa Fat 20 at $439.99 states 750 W rated like this one, but advertises 28 mph without saying whether that comes from the throttle, so it cannot be given a class. The DEEPOWER QS7 has the largest battery and real rear suspension, and a manual that contradicts its listing on speed. If you want the moped shape with a certification you can show someone and hydraulic brakes, the Macfox X1S at $1,399 costs much more and is the cleaner bike.

Buy it if you want the moped look at $499.99 from a listing that commits in writing to 750 W rated, 20 mph and Class 2, you will leave the speed setting where it ships, and your rides are under about 25 miles. Skip it if you need a named UL 2849 certificate for a building or a city, if you want a brand with years of owner reports behind it, if the 30 mph setting would tempt you on public roads, or if you live in New Jersey and do not want to license, register and insure a throttle e-bike.
