52 Volts. 15" Step-Thru Freedom. 20" Fat Tire Agility. The Most Accessible Muscle on Two Wheels.
Most fat-tire electric bikes are heavy, lumbering tanks designed exclusively for six-foot riders with wide open garages. If you want true all-terrain traction, you’re usually forced to wrestle with a towering top tube, awkward balance, and an oversized 75-pound frame. The Higgs ST completely flips the formula. Engineered with an ultra-low 15-inch stepover height and an ultra-compact 66-inch chassis, it is the lightest, most agile, and most universally accessible fat tire bike in the Murf family. Beneath its clean coastal cruiser silhouette sits an industrial 52V 15Ah (780Wh) Samsung battery pack feeding a 750W high-torque hub motor. Tap the thumb throttle to cruise effortlessly at 20 MPH, carve through tight city corners on agile 20" × 4.0" fat tires, and stop with total confidence using Tektro hydraulic disc brakes. Paired with a heavy-duty single-speed drivetrain that eliminates dropped chains forever and an included integrated rear utility rack, The Higgs ST delivers go-anywhere fat-tire stability in a package that fits comfortably in tight apartments, elevators, and suburban living spaces.
Statutory Class 2 Compliance Notice: The Higgs ST is engineered and certified as a street-legal Class 2 electric bicycle featuring thumb throttle operation and intelligent pedal assist up to 20 MPH. In strict adherence to 15 U.S.C. § 2085, 16 CFR Part 1512, and Texas Transp. Code § 551.102, this vehicle is fully permitted on public streets, designated bike paths, and multi-use greenways without requiring a motor vehicle driver's license, license plate, state vehicle registration, or annual safety inspection.
Who's This For
Tired of awkward leg swings over tall top tubes, heavy frames that feel unwieldy in tight corners, or cheap step-thrus that rattle and flex under pressure? Want a compact, low-step fat tire cruiser that packs 52 volts of relentless hill power, fits in an elevator, and turns heads wherever you ride?
What you can do:
- Mount and dismount with total ease via an ultra-low 15" standover height—perfect for shorter riders, older adults, or those with hip/knee mobility limitations
- Cruise up to 20 MPH on pure thumb throttle for sweat-free morning errands and casual boardwalk rides
- Navigate tight apartment hallways, elevators, and compact storage areas with an ultra-short 66-inch total length
- Float over crushed gravel, cobblestones, and packed sand with high-volume 20" × 4.0" fat tires
- Flatten steep neighborhood climbs without motor hesitation backed by high-voltage 52V torque (85Nm)
- Ride 30 to 60 miles per charge with an IPX6 water-resistant battery enclosure engineered for rain, puddles, and coastal salt air
- Stop authoritatively in all weather conditions with Tektro hydraulic disc brakes and 180mm stainless steel rotors
- Enjoy zero drivetrain headaches with a heavy-duty single-speed chain line—no derailleur hanger bends, gear clicks, or dropped chains
- Haul groceries, work bags, or beach gear on the rugged frame-integrated rear cargo rack included standard
- Fit multiple household riders from 4'10" to 6'4" comfortably with upright BMX handlebars and quick-adjust seat geometry
What This Bike Actually Solves
The Intimidating Fat Tire Standover Height
The Problem: Traditional 26" fat tire bikes have standover heights of 28" to 32", making mounting a high-stress, off-balance hurdle for anyone under 5'8" or with joint stiffness.
The Solution: The Higgs ST drops the standover to an ultra-accessible 15 inches. Riders step straight through and touch both feet flat on the ground at stops with complete composure and dignity.
The "Fat Tire Too Big for Urban Life" Problem
The Problem: Standard fat tire bikes measure over 75 inches long and weigh over 75 lbs, making them impossible to fit inside residential elevators, vehicle trunks, or apartment living spaces.
The Solution: Compact 20" wheels keep the overall length to just 66 inches and total curb weight down to ~60 lbs—giving you all-terrain traction in an apartment-friendly footprint.
48V Battery Voltage Sag on Neighborhood Grades
The Problem: Generic 48V e-bikes suffer steep voltage drops under load, leaving riders stalling out on steep neighborhood hills once the battery gauge drops below 50%.
The Solution: The 52V electrical architecture maintains steady operating voltage under load, delivering consistent starting torque and hill-climbing thrust right down to the final miles of your charge.
Real-World Riding Scenarios
The Relaxed Saturday Farmers Market Run (9:30 AM)
9:30 AM. Saturday morning. You step straight through the 15" frame in casual weekend clothes, strap a tote bag to the integrated rear rack, and glide 4 miles down the neighborhood greenway at 18 MPH. You hop off smoothly between market stalls, browse freely, and step right back on without struggling to hold a heavy bike upright.
The Win: Zero parking stress, effortless low-step mounting, and smooth, sweat-free weekend cruising.
The High-Density Apartment Commute (Daily)
8:15 AM. You roll the compact 66" Higgs ST directly into the residential elevator, exit smoothly into your apartment hallway, and charge the IPX6 battery indoors. On the road, the 20" fat tires soak up sidewalk seams and streetcar tracks with effortless composure.
The Win: Full 52V fat tire capability with zero hallway wrestling, tight-turn stress, or outdoor theft anxiety.
The Multi-Generational Family Fleet Bike (Sunday 2:00 PM)
Sunday afternoon. A 4'11" teen needs to run a quick errand to the market, and later a 6'2" adult wants to cruise to the park. The upright BMX handlebars and open 15" low-step chassis adjust in seconds to provide an ergonomically perfect fit for both riders.
The Win: One single high-performance machine that serves every rider in the household with equal comfort and confidence.
