The Hiboy EX6 Step-thru Fat Tire Electric Bike solves a problem most spec sheets never mention. Getting aboard a conventional frame means lifting a foot above saddle height and swinging it over the back. Do that with a stiff hip, a healing knee, a long coat or a full rack, and the answer is often that you simply do not ride today.
300 lb load · 41 mi on throttle · 75 mi on assist · 960W peak · 20×4 fat tires
Over the saddle
The top tube sets the floor. Your foot has to clear the saddle and the rack behind it, so the movement is a swing, and it needs balance on one leg while you make it.
Through the middle
The frame drops away between the wheels, so the same movement happens at roughly knee height with both feet close to the ground. That is the whole design and it is why this model exists.
Drawn to show the idea rather than the exact geometry. Hiboy does not publish a standover height for this model, so no figure is claimed here.
The frame that decides whether an electric bike gets used
We sell a lot of machines that live in hallways. The reason is almost never the motor or the battery; it is that getting on became a small daily negotiation and the negotiation started being lost.
A step-through removes it. That matters to riders with hip or knee trouble, to anyone still building confidence, and to people who ride in whatever they happen to be wearing. It also matters at every red light in a city, because getting a foot down and getting going again happens dozens of times on a short trip.
There is a second benefit that only shows up when the rack is loaded. On a conventional frame a full pannier is exactly what your foot has to clear. Here it is not in the way at all.
The trade is stiffness. Removing the top tube takes structure out of a frame, which is why Hiboy builds the down tube deep and curved on this one instead of running a thin tube. It is also why the load rating still reaches 300 lb.

The joint-highest load rating of any electric bike we carry
Only the EX9 matches it, and the EX9 costs $300 more. Against the rest of the range the gap is real, and it is the number to check first if you are a larger rider or you carry a load.
The rating covers rider and cargo together. If you are near the number, bring what you carry into any of our six shops and we will load it and let you ride it that way before you buy.
Three ways to ride it, and what each is worth
The battery is the same pack the EX6F carries, and it is the largest in the range short of the EX11. What changes is how much of the work you hand it.
Pure electric
Throttle only, no pedalling. The pack does everything, and this is the honest number to plan a commute around.
Pedal assisted
Your legs share the load and the range almost doubles. Up to 25 mph in this mode, against 20 on the throttle.
Motor off
Seven gears and nothing else. Useful when the battery is flat and useful when you simply want the exercise.
Both published figures assume a 165 lb rider. Cold weather, hills, a heavy load and low tire pressure each take a share, which is true of every electric bike on the market. The pack lifts out with a key so it can charge indoors, and a full charge takes seven to eight hours.
The strongest peak in the mid range, and where it costs you
500W rated and 960W peak is more headroom than the EX6F's 750W, on the same battery. That surplus is what gets a loaded machine moving from a standstill on a hill, which is the moment a weaker motor feels weak.
The honest counterpart is the brakes. This model runs mechanical disc brakes where the EX6F runs hydraulic, so it asks more of your hands, particularly in the wet and particularly with a load behind you. More power, less brake. That is the trade and it is worth knowing before you choose between the two.
Front shocks handle the rest. Combined with four inches of tire, that is enough for broken asphalt, gravel and packed snow.

The controls, the pack and the tire
Three components decide how an electric bike feels day to day, and none of them photograph well in a catalogue shot of the whole machine.
The display
Assist level, speed, battery and trip on one screen. On a machine with three riding modes and five assist levels, being able to read what you are in without stopping is most of the usability.
The battery
The 48V 14.5Ah pack sits in the down tube and lifts out with a key. That is what lets it charge on a desk while the machine stays in a hallway, and it is the single most useful feature on any electric bike kept in an apartment.
The tire
20 by 4 inches. The smaller diameter is what keeps the standover low enough for a step-through frame to work, and the four inches of width is what puts the grip back that a small wheel gives away.
Where a step-through frame actually goes
Snow, sand and gravel are all inside what four inches of tire will handle, and the 20-inch wheel keeps the centre of gravity low enough that a loaded rack does not make it twitchy.
What it is not is a trail machine. Front shocks and no rear suspension means rough ground at speed will come through the saddle, and the 15% climbing figure is honest about hills. Think broken city surfaces, towpaths and beaches rather than singletrack.
Where this electric bike sits against the rest
Six models is enough to be confusing, and the honest summary is that four of them are answering different questions rather than competing on quality. Here is how we actually talk a customer through it on the floor.
The EX6 and the EX6F are the closest pair, sharing a battery, a range figure and a tire size. Choose between them on frame and brakes, not on performance. The EX6 gives you 35 lb more load rating and the stronger peak motor; the EX6F gives you hydraulic brakes, a frame that folds, and a rider fit twenty inches wide instead of nine. If more than one person in the house will ride it, that fit range usually settles it.
Against the P6, the question is wheel size. Twenty-six inch wheels roll over a pothole more easily than twenty-inch ones, and the P6 has a stronger motor, but it puts them on a conventional frame with a smaller battery and a lower load rating. Bigger obstacles, or easier living: that is the choice.
The EX9 is the one to look at if your route is mostly pavement. It matches the 300 lb rating, weighs 59.5 lb, and its torque sensor makes it the nicest of the six to pedal. It gives up range and fat tires to do it. And the EX11 is a different category of machine altogether, with suspension at both ends and an 864Wh pack, at nearly twice the price.
Where the EX6 wins outright is value per pound carried. Nothing else in the range takes 300 lb for under nine hundred dollars, and nothing else makes getting aboard this easy.

Hiboy publishes a boxed weight for this model and no weight for the machine itself, so we have not printed one. Ask us and we will put an EX6 on the shop scale for you.
The EX6F carries the same battery on a frame that folds, with hydraulic brakes and a far wider rider fit, for $50 more. For pavement rather than gravel, the EX9 is lighter and quicker. Here is every fat tire electric bike we stock.
Try stepping through one. That is the whole test.

Hiboy EX6, answered
What does step-thru actually mean?
The frame has no high bar between the saddle and the handlebars. The tube drops low between the wheels instead, so you step through the gap at roughly knee height rather than swinging a leg up and over the back.
Who is a step-through frame best for?
Anyone who finds swinging a leg over awkward. That includes riders with hip or knee trouble, shorter riders, people building confidence, anyone riding in work clothes, and anyone whose rack is usually loaded, because a full pannier is exactly what your foot would otherwise have to clear.
How much weight can the EX6 carry?
300 lb for rider and cargo together. That is the joint-highest of any electric bike we stock, alongside the EX9.
How far does it go on a charge?
41 miles on the throttle alone, or 75 miles with pedal assist, both measured by Hiboy with a 165 lb rider.
How fast does it go?
20 mph on the throttle, and up to 25 mph in pedal assist.
Is the battery removable?
Yes. The 48V 14.5Ah pack comes out with a key so you can charge it indoors and leave the machine where it is. Seven to eight hours for a full charge.
What size rider does it suit?
Hiboy quotes 5′0″ to 5′9″, which is a narrow window. If you are taller than that, the EX6F fits 4′9″ to 6′5″ on the same battery. Come in and we will size you properly rather than guessing from a chart.
What brakes does it have, and how do they compare to the EX6F?
Front and rear disc brakes, mechanical rather than hydraulic. The EX6F uses hydraulic discs, which need less hand pressure and hold up better in the wet. If you ride year round or carry a lot, that difference is worth the $50.
What are the tires like?
20 by 4 inch pneumatic fat tires. The smaller wheel keeps the standover low, and four inches of tire gives grip on gravel, sand and packed snow. They hold air, so pressure wants checking, and we set it at every service.
Does it have suspension?
Front shocks. There is no rear suspension on this model. If you want both ends sprung, the EX11 is the only one in the range that has it.
How much does it weigh?
Hiboy publishes a 66 lb package weight and no figure for the machine on its own, so we have not printed one rather than guessing. Ask at any shop and we will weigh one for you.
Can I ride it in the rain?
It is IPX4 rated, so rain and wet roads are within it. One safety point worth stating plainly: never charge an electric bike that is wet, or one whose battery looks swollen or damaged. Bring it straight in to us instead.
Why is the Black one unavailable?
Black is out of stock at Hiboy. White is shipping now, at the same price. Most of Hiboy's own photography for this model shows the Black machine, so it is worth being clear about which one you are actually ordering.
How is it different from the P6?
Wheel size and frame. The P6 runs 26 by 4 inch tires on a conventional frame with a 750W motor, and it costs $200 more. The EX6 is the step-through with the bigger battery, longer range and a higher load rating. The P6 rolls better over big obstacles; the EX6 is far easier to live with.
Who services it, and what warranty comes with it?
Our own technicians, at all six shops, with express service available at every one. Hiboy is a brand we carry, so it comes with a year of warranty cover and we handle the claim with Hiboy for you. We service any brand, whether you bought it from us or not.
