Overview: What the Aipas M1 Pro Brings to the Trail
The Aipas M1 Pro Electric Bike is positioned as a do-it-all, high-power fat-tire ebike for riders who want speed, range, and off-road capability without sacrificing daily usability. On paper it’s an impressive package: an 1800W peak brushless motor producing 110 Nm of torque, a 48V 17.5Ah removable battery, 26″ x 4.0″ fat tires, full dual suspension with a lockable fork, a 7-speed drivetrain, and 180mm mechanical disc brakes. The spec list also includes a step-thru frame option, an LCD display with a USB charging port, and five riding modes (Throttle, Pedal Assist, Cruise, Normal, Walk). Aipas claims a top speed of 36 MPH and a wide range window of 25–85 miles depending on riding conditions. This review takes a close look at how those numbers translate to real-world riding—performance, handling, comfort, battery endurance, and the practicalities of living with a heavyweight electric mountain bike.
Power and Performance: Speed, Torque, and Climbing
If you want acceleration and hill-climbing capability, the M1 Pro’s 1800W peak motor delivers. In throttle-only sprints it feels punchy and responsive, getting up to speed quickly even with a heavier rider or a loaded rack. The 110 Nm of torque makes a real difference on steep climbs—claims of managing grades up to about 23° are believable for short stretches when the battery is healthy. Top speed figures (36 MPH) are attainable on flat roads under ideal conditions, although local regulations often require limiting speeds on public streets; also speed will vary based on rider weight, wind, and grade. The integrated 7-speed drivetrain helps keep the motor in a comfortable cadence range when pedaling, and pedal assist plus the throttle gives flexibility for riders who want exercise, efficiency, or simply easier commuting. One practical note: at higher speeds the bike’s geometry feels stable but you’ll notice the mass of the bike—fat-tire rolling resistance and weight make it less sprightly than a nimble commuter, which is expected given the M1 Pro’s all-terrain ambitions.
Battery and Range: What to Expect from the 48V 17.5Ah Pack
The removable 48V 17.5Ah battery is one of the M1 Pro’s strong selling points. Aipas states a range between 25 and 85 miles, which is a wide window that reflects differences in riding mode, terrain, rider effort, and load. In practice you can expect the lower end of that range when riding at high speeds, using heavy throttle, or tackling lots of elevation—realistic high-speed, off-road use will put you closer to the 25–40 mile mark. In conservative pedal-assist city rides on flat terrain, the battery will stretch much farther, especially if you make smart use of PAS and cadence. The removable design makes balancing charging and security easy: bring the battery inside to charge overnight and swap back in the morning. Charging time is typical for the class (several hours to full from empty), but Aipas provides a lockable battery mount which is convenient for urban use. As always, expect battery longevity to depend on charging habits and storage conditions—treat it like any lithium pack and avoid deep discharges whenever possible.
Ride Quality: Suspension, Tires, and Braking
The M1 Pro’s full suspension setup—lockable front fork and rear shock absorber—combined with 26″ x 4.0″ fat tires produces a plush, confidence-inspiring ride across varied surfaces. On gravel, sand, and snowy or soft trails the 4.0″ tires float and grip much better than narrow mountain bike tires, smoothing imperfections and letting you maintain traction where a standard wheel might bog down. The ability to lock the front fork is a useful addition for long road stretches where you want more pedaling efficiency. Braking comes courtesy of 180mm mechanical disc brakes; they deliver solid stopping power for most scenarios, though hydraulic discs would offer more modulation and bite under heavy loads or steep descents. The mechanical setup is easier to maintain and repair, and it still outperforms rim brakes by a wide margin, but riders pushing extreme downhill speeds should be mindful of fade on extended descents. Handling is stable rather than nimble—again, the bike’s mass and fat tires are responsible—but stability is an advantage for carrying gear and for novice riders who appreciate forgiving steering.
Comfort, Controls, and Practical Features
Aipas has thought through ergonomics and practical rider touches. The step-thru frame makes mounting and dismounting significantly easier, which broadens the bike’s appeal to riders of different ages and flexibility levels. The saddle is described as wide, soft, and height-adjustable—comfortable for medium-distance rides and adjustable enough to dial in a good position. The LCD display is clear and useful, showing speed, distance, battery level, and mode at a glance; having a USB charging port on the controller is a modern convenience for navigation or phone charging. The five riding modes (Throttle, Pedal Assist, Cruise, Normal, Walk) give you flexibility in how you use power, and the built-in cruise function is handy for sustained highway-like stretches. Assembly is straightforward: the bike comes about 95% pre-assembled, and Aipas provides an assembly video and user manual. Shipping reportedly uses FedEx for ebikes, with accessories through USPS or DHL; processing typically occurs within 48 business hours. Overall, the practical features make the M1 Pro a versatile option for commuting, touring, or weekend exploration.
Pros, Cons, and Final Verdict
The Aipas M1 Pro offers a compelling mix of power, range, and off-road capability at a price point that undercuts some premium brands. Pros include muscular 1800W peak motor performance with 110 Nm torque for strong acceleration and climbing ability, a removable 48V 17.5Ah battery with excellent potential range when used conservatively, full suspension and fat tires that soothe rough terrain, and practical touches like a step-thru frame, USB charging, and multiple riding modes. The bike is well-suited to riders who want a do-it-all ebike for mixed terrains—commuters who need robustness, weekend adventurers who want to tackle sand or snow, and riders who prioritize comfort and power.
On the flip side, there are a few trade-offs. The heavy build and fat tires mean the bike won’t be as nimble or efficient as lighter commuters on pavement; mechanical disc brakes, while reliable, aren’t as performance-oriented as hydraulic options for aggressive downhill riding; and real-world high-speed range will be substantially less than the optimistic 85-mile figure if you ride fast or on hills. Additionally, local speed limits and regulations may restrict the use of the full 36 MPH top speed in many regions, so check local laws. Assembly and service depend on the vendor and shipping logistics—while 95% pre-assembled status and video guides help, some riders may prefer local bike shop assembly or an initial tune-up.
Bottom line: if you’re looking for a powerful, all-terrain electric bike that balances comfort, range, and rugged capability, the Aipas M1 Pro is a strong contender. It’s especially attractive for riders who want fat-tire traction and dual suspension without paying the premium for boutique brands. Be realistic about the trade-offs—weight, braking performance, and speed legality—and the M1 Pro will reward you with confident handling, muscular acceleration, and a versatile platform for daily riding and off-road exploration alike.
