Biktrix Stunner LT 5 Review: Big Torque and Range at a Premium for $2,649

What the stars are rated against
The stars compare this bike with other commuter e-bikes we have scored — 21 of them, priced $1,854–$3,444. They are a ranking inside that group, not an absolute grade: four stars means it beats most of that set on the measure, not that it hits some fixed standard.
Peers are drawn from a tight price band around this bike, so a $1,000 commuter is judged against other $1,000 commuters rather than against machines costing three times as much. Change the group and the stars would change with it.
The headline Genius Score is not decided by that group alone. It blends the category ranking above with a market-wide view across every bike we publish, so a bike cannot climb simply by sitting in a weak category. How we score.
At $2,649, the Biktrix Stunner LT 5 asks you to pay up, and what that money buys is comfort and grunt rather than a bargain. The 24-inch fat tires take the sting out of broken pavement and gravel, pulls a loaded bike away from a red light without drama, and a big backs a claimed 50 miles of range.
It's a bike with a , so you can cruise up to 20 mph without pedaling at all. That's a real help on hills and pulling away from stops, and it's what makes this an any-day, any-outfit commuter. The honest catch is value: for this kind of money, several fat-tire commuters cover the same ground for less.
Pros & cons
What we like
- from the pulls a loaded bike up hills and away from stoplights with real confidence.
- A lets you ride at up to 20 mph without pedaling, which is handy on tired days and steep starts.
- The 816Wh battery backs a 50-mile claim, so real-world range holds up well for a fat-tire bike.
- 24x4-inch fat tires and give you a cushioned ride and strong stops on rough roads.
- A 330-lb leaves plenty of headroom for a passenger, a loaded rack, or a big grocery run.
Worth weighing
- The price is the weak spot: at $2,649 you're paying a premium the rest of the bike doesn't quite earn back against cheaper rivals.
- At about 73.6 lb it runs heavy even by fat-tire standards, so wrestling it up stairs or onto a rack takes some effort.
Key specs
The motor & power
The 750W here is tuned more for pulling power than top speed, and the number that tells the story is . That's a strong figure, enough to get a heavy fat-tire bike and a full load moving up a hill without you having to stand on the pedals.
, so judge the motor on its steady 750. For commuting, that's plenty to hold 20 mph and climb without straining.
Because it's a bike with a , you can twist and go up to 20 mph without pedaling. Riding on the throttle is the easy way up a hill or away from a stop, and the trade-off is that leaning on it draws the battery down faster than pedaling along with the motor.
Range & battery
The base pack is an 816Wh Samsung battery, and Biktrix quotes up to 50 miles on a charge. For a fat-tire bike hauling this kind of weight, 50 miles is a strong claim.
That figure assumes gentle, flat, pedal-assisted riding. Once you add fat tires, hills, a heavier load, and time spent on the throttle, plan on landing somewhere below it on a normal week. Charging every few commutes rather than nightly is a fair expectation.
Biktrix sells the Stunner LT 5 with several battery choices, from this 816Wh base pack up to a 1,200Wh unit. The 50-mile claim and our scoring use the standard 816Wh battery, so if you pay to upsize, expect more range than the base numbers suggest.
Ride & components
The 24x4-inch fat tires are the headline for comfort. They add cushioning that takes the edge off cracked pavement, gravel, and curbs, so a rough commute is far less jarring.
Stopping comes from Biktrix dual-piston on 160mm rotors, which matters on a heavy bike that can be carrying a lot.
Shifting is a Shimano 8-speed setup with an 11-32t range. It's a basic, dependable drivetrain that covers commuter gearing fine, even if it isn't fancy. And the 330-lb gives you real room to load up on top of your own weight.
Price & value
At $2,649, the Stunner LT 5 sits firmly in premium territory, and that's the part to think hardest about. You're paying for the big battery, the strong torque, and the fat-tire comfort, and all three are genuinely there.
The catch is that value is this bike's soft spot. Against the 16 commuters we scored it with, several deliver comparable range and a similar 750W motor for a few hundred dollars less, which is why its Genius Score of 65 out of 100 lands in solid-but-not-standout territory. Whether it's worth the premium comes down to how much you value the comfort and grunt.
Who it's for
The rough-road comfort seeker
If your commute is full of potholes, gravel, or beat-up curbs and you're tired of getting rattled, the 24-inch fat tires and cushioned ride are exactly what you're paying up for here.
The no-pedal cruiser
If you'd rather twist a and let the motor do the work on tired days or big hills, this one lets you ride up to 20 mph without pedaling, backed by enough torque to still feel strong when you do pedal.
The budget-first shopper
If the bottom line matters most, this is a tougher sell, since the premium price is exactly where cheaper fat-tire commuters close the gap.
The speed chaser
If you want to legally cruise faster than 20 mph, this caps out there as a bike, so a quicker Class 3 commuter would suit you better.

How it compares to its siblings
The Stunner LT 5 is the most expensive model in the family at $2649, but it posts the lowest Genius score (65) and the smallest battery (816Wh vs 960Wh on the Step-Over Auto and LT 8). It is the lightest Stunner at 73.6 lb and lists a 1000W peak motor spec the others don't have, but it also drops to 160mm rotors versus 180mm on the Step-Over Auto and LT 8. Unless shaving a few pounds is the priority, the extra money here doesn't clearly outperform the cheaper siblings.
