If you have ever wanted a chill, beach-cruiser style ride that can still hang with city traffic, the Hiboy EX9 is right in that sweet spot. It is sold as a commuter eBike, but on the road it feels like something you would see rolling down a boardwalk to breakfast, not bombing a downhill trail. In this review we are talking real-world comfort, honest range for heavier riders, and whether this thing is actually worth your money.
Overview of the Hiboy EX9
On paper, the Hiboy EX9 is a class 3 urban commuter. On the road, it rides like a relaxed beach cruiser that just happens to hit 28 mph with pedal assist. It is one of the few bikes in this price bracket that is not rocking fat tires, and that alone gives it a very different feel compared to a lot of chunky, moped-style eBikes.

Why it works for commuting or cruising
The EX9 hits that nice middle ground. With pedal assist it can sit around 25 to 28 mph, so keeping up with city traffic on surface streets is not a problem. The step-through frame makes it easy to hop on and off in beach clothes, regular shorts, or whatever you throw on to go grab coffee.
It feels much closer to an Aventon-style comfort cruiser than a bulkier moped bike, just with a slightly more relaxed posture.
Comfort and fit for real riders
Here is the big question many people actually care about: does it fit normal, not-supermodel bodies?
The reviewer is 6’1″, 250 lb, and fits it just fine. No weird knee angles, no cramped cockpit, no “this is clearly sized for a 140 lb college kid” problem. The listed max load is 330 lb, so there is some headroom for bigger riders or a loaded rack.
A lot of the comfort comes from three things working together: the step-through frame so you are not swinging a leg over something tall, a soft squishy saddle that basically acts as fake rear suspension, and a very upright riding position that feels perfect for boardwalk or neighborhood cruising.
Perfect for most adults from 4’9″ to 6’5″. If you liked how bikes like the Aventon Pace or Level feel, this sits in that same comfort lane.
Adjustable handlebar and display
The handlebar setup is surprisingly nice for this price.
You get:
- A 60-degree adjustable handlebar that you can rotate more upright or more forward.
- A built-in stem display that can tilt, so you can actually see your speed without hunching down.
- An 80 mm front fork with preload adjustment and a lockout for smoother pavement days.
You can run it tall and upright for cruiser vibes, or tilt everything a bit forward if you want a slightly more “commuter” feel.
Fixing handlebar wiggle under hard braking
There is one little quirk. The integrated stem module can move a bit if you are heavier and slam the front brake. The fix is simple: tighten the main front bolt, and if that is not enough, peel the two stickers on the side and snug down the two hidden screws inside. Once that is done, it feels much more solid.
Power and motor performance
The heart of the hiboy ex9 is a 750 W rear hub motor, rated up to 1000 W peak, paired with a dual-sided torque sensor. In practice, it has a more relaxed, smooth feel than a lot of on-or-off cadence setups.
You get three assist levels. On pedal assist, the bike can reach 28 mph, which is what makes it a class 3. On throttle only, it is capped at 20 mph to stay inside regulations. The important bit is that it does not feel like you are grinding your legs off just to hit those higher numbers.
At higher assist, the behavior starts to feel more like a speed sensor. The harder and faster you spin, the more the bike wants to go, until you are basically topped out and your legs are just ghost pedaling.
Pedal assist levels breakdown
Here is how the three levels feel in real use:
- PAS 1: Easy cruise
Sits around 12 mph. Light assist, you can chat, look around, not sweat. - PAS 2: Daily rider mode
Noticeably more pull, but you still feel like you are doing some work. Good for most flat city riding. - PAS 3: Max effort
This is where it starts behaving more like a speed-based system. Faster pedaling equals more speed, right up into the mid to high 20s.
You are not buying this thing to race an eMTB, but it has more than enough punch for commuting and casual fun.
Brakes and suspension setup
Stopping power is handled by 180 mm disc brakes with dual-piston calipers. They are unbranded, but they work fine for street use. You are not bombing steep mountain trails on this, you are rolling city streets and boardwalks.
Up front, you get that 80 mm suspension fork with both preload and a lockout. For most people, leaving a bit of squish in there takes the edge off cracks, joints, and random bad pavement.
There is no rear suspension at all, it is a hardtail, and that makes sense. This bike is not meant for serious off-road use; the wide saddle and upright posture are the comfort system.
This is a street-first setup, not an off-road rig.
Real-world braking feel
At 20 to 25 mph on pavement, the brakes feel controlled and predictable. No fading, no nasty surprises, and no “am I going to overshoot this intersection” panic. For a casual cruiser at this price point, that is exactly what you want.
Tires and ride efficiency
The tires are 26 x 2.5 inches, which is an interesting middle ground. Not skinny road tires, not full-blown fat tires.
That gives you:
- Enough width for decent grip and comfort on streets or boardwalk.
- Lower rolling resistance than a 4 inch fat tire, so the bike feels more efficient.
If you are coming from chunkier fat bikes, this will feel quicker to spin up and a little easier on battery, especially on long flat rides.
Battery and range expectations
Power comes from a 48 V, 11.6 Ah battery, for a total of 556 Wh. It is slim and tucked into the frame nicely, which helps the clean look, but it also means you are not carrying some giant 20 Ah pack.
The claimed range is 31 to 62 miles. For a light rider in low assist, that is not crazy on paper, and you will see similar claims on the Hiboy EX9 listing with Canadian specs.
For a 250 lb rider living on throttle at 20 mph, the realistic number is very different. In testing, after 6.4 miles of throttle-only riding, the display still showed 100 percent. Based on that behavior and the motor size, a realistic 30 miles of throttle-only for a heavier rider is reasonable.
Sixty miles, however, is fantasy unless you are light, in assist level 1, and pedaling like you actually mean it.
Charging and USB power
The included charger is a 2 A unit. From empty to full, you are looking at roughly 5 to 6 hours on the wall.
There is also a USB Type-C port built right into the stem module. You can plug your phone in and keep it topped off while you ride, which is perfect if you are running GPS or music on longer cruises.
Price, value, and who this bike is for
The hiboy ex9 comes in at $1,299 before any discounts. For a 750 W class 3 commuter with a torque sensor, integrated display, and a 330 lb max load, that is strong value.
Who actually fits this bike best:
- People living near a beach or boardwalk who want a relaxed cruiser that still has real power.
- City riders who want to stay legal at 20 mph throttle and 28 mph pedal assist.
- Heavier riders who are tired of “up to 60 mile range” marketing that only works for tiny humans.
If your idea of a good ride is rolling to breakfast, hitting the pier, then cruising home, this fits.
What the EX9 gets right
There is a lot to like here, especially at this price:
- Rear brake light baked in for visibility.
- Integrated stem display that tilts and looks clean.
- Type-C port with the assist buttons right on the module, so controls stay tidy.
- Street-oriented 26 x 2.5 tires that roll smooth and feel efficient.
- Adjustable handlebar and cockpit that work for a wide range of body sizes.
It really does what it looks like it should do, which is not always the case with budget-ish eBikes.
Minor gripes and things I would change
Nothing here is a deal-breaker, but a few things stand out.
The big one is speed on throttle. I would love to see full 28 mph available without pedaling. The bike has the motor for it, but the class 3 rules keep throttle limited to 20 mph.
I would also like slightly fatter tires for extra comfort, maybe in the 2.8 to 3 inch range, just to soak up rougher paths better without going full fat-bike.
Finally, that integrated handlebar module being able to shift under heavy braking until you tighten the hidden screws is annoying. It is easy to fix, but it should ship locked down.
Range reality for bigger riders
The 60 mile claim only makes sense for light riders in low assist with steady pedaling. If you are anywhere near 250 lb and using throttle a lot, think 25 to 35 miles, not 60. That is still solid for the battery size, just keep your expectations honest.
Final thoughts
The hiboy ex9 is not a wild, off-road animal. It is a relaxed, comfortable, class 3 beach cruiser that just happens to be shaped like a commuter. For boardwalk mornings, neighborhood rides, and laid-back city trips, it hits the mark and does it at a price that will not wreck your budget.
If you want max power and huge range, this is not your bike. If you want an affordable, easygoing eBike that stays legal, fits bigger riders, and feels good doing simple rides, the Hiboy EX9 makes a lot of sense.
