The Jasion EB5 MAX is a full-size, fat-tire e-mountain bike that’s been tuned for real-world versatility.
It marries a 1500W peak rear-hub motor with a 48V 15Ah (720Wh) removable battery, a color LCD with cruise control and password lock, and a set of practical add-ons—full fenders and a rear rack—right out of the box.
On paper, it promises 28+ mph top speed, up to 65 miles of pedal-assist range, and tough 26″×4.0″ tires for mixed terrain.

I spent time riding the EB5 MAX on neighborhood streets, a local gravel loop, and a short, rutted fire road I use to test traction and hill-climbing.
The big takeaways: it accelerates with authority, climbs better than typical 750W fat bikes, and rides smoother than I expected for an all-steel frame thanks to the lockable suspension fork and the large-volume tires.
It is not a featherweight, and the power delivery is enthusiastic, so you’ll want to understand the assist levels and cruise control early on—but once dialed in, it’s a confident, go-anywhere companion.

Jasion has been steadily iterating its EB-series bikes, and the “MAX” badge here isn’t marketing fluff.
The brighter headlight, flashing brake light, ESS-style brake alert, color display with USB-C phone charging and password lock, plus the factory-installed rack and fenders all make this feel like a complete commuter-meets-trail package rather than a bare frame you need to accessorize later.
If you’ve been looking for a fat-tire e-bike that can handle weekly chores and weekend trails without costing luxury-bike money, this is a serious contender.

Is Jasion EB5 MAX for you?

If your short list includes a fat-tire bike that can play commuter on weekdays and explore dirt and sand on weekends, the EB5 MAX hits the brief.
The 1500W peak motor is energetic enough for steeper neighborhoods and loose surfaces, while the 26×4.0” tires add confidence on gravel, grass, and snow.
The 720Wh battery is large for this price bracket and supports meaningful range if you use pedal assist rather than living on throttle alone.

This model suits riders who value ruggedness and utility—think mixed-terrain commuters, new riders who want margin for error from big tires, or anyone hauling groceries or camera bags on the sturdy rear rack.
The generous 400-lb max load is helpful for bigger riders or those carrying gear.
With a recommended rider height range of around 5’5” to 6’5”, it covers most adults, though smaller riders may find the stand-over tall compared with step-through frames.

It’s less ideal if you need a super-light e-bike to carry up multiple flights of stairs, or if you prefer the ultra-quiet, always-on feel of mid-drive systems that multiply your pedaling torque.
This is a hub-drive machine with zest; it’s happiest when given room to roll.

Budget-wise, the EB5 MAX is a value / lower-mid range fat-tire e-MTB that overdelivers on included equipment.
It is beginner-friendly—especially thanks to the big tires, simple 7-speed drivetrain, and walk-assist—but the quick acceleration means first-timers should start in lower PAS levels and learn the cruise control before riding in crowded areas.

What We Like About the Jasion EB5 MAX

Power delivery is the star.
The 1500W peak motor spools up quickly, making short work of rolling hills and sandy patches that bog down weaker hub drives.
It isn’t just about speed; the motor’s climbing grit lets you stay seated and composed on steeper ramps where many fat bikes demand a standing mash.

Range is legitimately useful.
With the 48V 15Ah battery, I could plan mixed routes—pavement to gravel to sandy trail—and not worry about limping home.
Conservative riders using PAS 1–2 will see the high end of the claimed range on flatter routes, while throttle-heavy riders can still cover real distance without range anxiety.

Jasion nailed day-to-day usability.
The color display is clear, the password lock discourages casual tampering, and the cruise control reduces wrist fatigue on longer flats.
USB-C charging for your phone is surprisingly handy, and the brighter headlight plus flashing brake light add visibility that’s missing on many budget bikes.
Having fenders and a rear rack already mounted saves money and install time.

Ride comfort exceeds expectations for a steel hardtail.
The lockable front suspension and 4.0″ rubber soak up chatter, and the ergonomic saddle is better than typical budget seats.
Mechanical 180 mm discs aren’t boutique parts, but they’re strong and predictable, and replacement pads are cheap and widely available.

Finally, the frame feels stout.
With a 400-lb max payload and wide tires, this bike doesn’t flinch at loaded rides.
It’s a platform you can grow into—add baskets or panniers, play with tire pressure for sand or snow, and it keeps up.

What We Don’t Like About the Jasion EB5 MAX

At roughly 83 lbs, this is a heavy bike.
Weight disappears once you’re moving, but it’s noticeable when lifting onto a hitch rack or maneuvering in a hallway.
If you need to carry your bike upstairs frequently, consider a step-through or lighter model.

The motor’s eagerness can be a double-edged sword for new riders.
PAS 1 is quite usable, but jump up levels too quickly and the surge may surprise you on loose ground.
Take a day to learn the assist curve and cruise control, and set a conservative speed limit in the display if you ride crowded areas.

Mechanical disc brakes work well and are easy to service, but heavy riders who descend long hills regularly may want to budget for metallic pads or a future hydraulic upgrade.
Likewise, while the 7-speed drivetrain is reliable, experienced mountain bikers may wish for a wider gear range to fine-tune cadence at higher speeds.

Lastly, the color choices are nice, yet the frame only comes in one size.
It fits a broad range, but very small or very tall riders may struggle to achieve a perfect fit without swapping stems or seatposts.

Feature Opinion:
This is the rare sub-$1k fat-tire bike that arrives “complete.”
The software features—password lock, cruise control, phone charging—aren’t gimmicks; they reduce friction in daily use.
The 720Wh battery is big enough for meaningful rides without babying assist levels, and the lights and rack/fenders turn it into a year-round utility machine.
I’d love to see hydraulic brakes at this weight, but the 180 mm mechanicals are adequate and easy to service.

Real-World Riding Impressions

Acceleration & Speed
From a stop, the EB5 MAX steps out assertively, especially in PAS 3+.
If you’re new to e-bikes, start lower—PAS 1 or 2—so you can match pedal cadence to motor assist smoothly.
Once rolling, maintaining 20–25 mph on flats is easy with light pedaling, and unlocking the higher limit makes quick work of long, empty straights.

Climbing
On my test hill—a short punch that hits double-digit grades—the EB5 MAX stayed seated and climbed with composure.
Hub motors typically fade as grades increase, but the peak output here helps you crest without standing sprints.
If you keep cadence steady and select a sensible gear, it feels like a chairlift.

Handling & Comfort
Fat tires transform mixed-surface confidence.
On loose gravel, you can choose lines rather than fear them, and soft sand sections are surprisingly rideable with a small speed run-up.
I ran 18–20 psi off-road and ~24–26 psi on pavement; the wide contact patch and the fork’s initial travel absorb washboard chatter and curb drops.
The ergonomic saddle is better than average, and I didn’t reach for my own seat right away—a good sign.

Braking
There’s a lot of mass to control, but the 180 mm rotors with decent pads hauled the bike down predictably.
Modulation is linear; two-finger braking is enough at urban speeds.
On long, loaded descents, I’d manage speed earlier and consider metallic pads later if you ride in wet, gritty conditions.

Noise & Vibration
The hub motor has a faint whir under load, typical for the class, and the steel frame keeps creaks at bay.
No rattle from the fenders or rack once all fasteners were snug.
Chain slap is mild thanks to fat-tire damping and modest trail chatter.

Display & Controls
The color LCD is easy to read even at noon.
Cruise control engages cleanly, and the speed-limit setting is handy if you ride shared multi-use paths.
USB-C charging for a smartphone is honestly one of those quality-of-life features you don’t know you need until your navigation app eats battery on a long ride.

Utility & Cargo
The rear rack handled a loaded pannier plus a small top trunk without flex drama.
Mounting points allow baskets or a child seat with the right adapter.
With the fenders, wet commutes are less messy, and the flashing brake light is a genuine safety upgrade for dusk rides.

Setup, Fit & Maintenance Notes

The bike arrives well-protected, with assembly steps within the comfort zone of a first-timer: install front wheel and fender, handlebar, pedals, and adjust brakes/derailleur if needed.
The included tool kit covers the basics, though a torque wrench is always a good idea for stem and axle nuts.

At one frame size, fit is generous rather than surgical.
Most riders in the recommended range can dial it with saddle height and a few spacers.
If you’re at the very low or high end of the range, consider swapping stems to fine-tune reach.

Mechanical discs are a blessing for home mechanics—affordable pads, easy cable swaps.
Keep cables lubed, check rotor bolts every few weeks, and bed in new pads to avoid glazing.
The 7-speed drivetrain is ubiquitous; any bike shop can tune it, and parts are inexpensive.

For battery longevity, store between 20–80% when not riding for weeks, avoid leaving it on a hot car rack, and charge after rides rather than topping from full every time.
Tires respond well to pressure tuning; don’t be afraid to experiment for comfort versus rolling resistance.

Safety, Class & Etiquette

With 28+ mph capability, ride defensively and obey local class rules on shared paths.
Set the speed limit to suit your environment and your comfort level; there’s no prize for riding at unlock speed through a farmer’s market.
The bright headlight and flashing tail make you more visible, but add reflective tape to panniers and consider a helmet with integrated lights if you commute at dawn or dusk.

Braking distance grows with speed and mass.
On unfamiliar descents, feather brakes early, keep your weight low, and let the tires do their job.
Fat tires excel off-road but can “float” on painted lines in the rain—cross them upright.

Who Should Consider Alternatives?

• Walk-up apartment dwellers: If you must carry a bike upstairs, an 83-lb fat bike will test your patience.
  Look for a lighter, smaller-battery commuter or a step-through with a handle cutout.
• Performance mountain bikers: If you care about suspension kinematics and ripping singletrack, a mid-drive e-MTB with multi-link rear suspension and hydraulic brakes is the right tool—at far higher cost.
• Riders in constant rain & long descents: The mechanicals are fine for most, but if you descend long hills daily, a bike with hydraulic discs out of the box might be worth the premium.

Value & Long-Term Outlook

What sets the EB5 MAX apart in its bracket is how much “complete bike” you get without nickel-and-diming.
Between the battery size, motor punch, and stock accessories, it’s ready to ride as a commuter or weekend explorer the day you finish assembly.
The components are common standards—7-speed drivetrain, mechanical discs, 26×4.0” tires—so upkeep is inexpensive and parts are everywhere.

The steel frame should age well if you keep bolts torqued and add a dab of assembly paste or anti-seize where needed.
A future upgrade path is clear: puncture-proof tubes or tubeless conversion, metallic pads, maybe a dropper post for mixed terrain, and a bar-end mirror for city riding.
Nothing is exotic or proprietary, which is exactly what you want in a value-oriented workhorse.

Final Breakdown

9.2 / 10

The Jasion EB5 MAX delivers the kind of all-rounder experience most riders actually need: strong motor, meaningful battery, big-tire comfort, and practical accessories built in.
It’s not the lightest or the fanciest, and I’d love hydraulic brakes, but those trade-offs are sensible at this price.
What you get is a confident fat-tire bike that climbs better than expected, cruises farther than most in its class, and arrives already set up for real life with fenders, rack, bright lights, and a smart display.

If your checklist reads power + range + everyday utility on a sane budget, add the EB5 MAX to the top of your test-ride list.
Dial the PAS to your liking, set a speed limit for your routes, and you’ll have a reliable, fun machine for commutes, errands, and weekend adventures alike.
