Aipas M2 Pro E-Bike Review: 36 MPH Top Speed, Dual Suspension, 85-Mile Range

The Aipas M2 Pro is a big-power, fat-tire, dual-suspension e-MTB aimed at riders who want car-like shove with the comfort and stability of 26” × 4.0” rubber. It touts an 1,800W peak rear hub motor, a 48V 17.5Ah semi-integrated battery, and a headline top speed of up to 36 mph (claimed). On paper, that’s serious performance for a do-it-all fat-tire commuter and trail explorer.

Over several weeks I used the M2 Pro as a daily grocery runner, a weekend gravel cruiser, and a short-distance trail bike. I paid close attention to ride feel, control ergonomics, braking authority, and real-world range at different assistance levels. I also looked at long-term ownership details—assembly, maintenance access, cable routing, and how well the frame and components hold up to mixed-surface riding.

Aipas is a value-driven brand known for high-spec hub-drive bikes at approachable pricing. The M2 Pro follows that formula but adds useful touches such as a USB charging port on the display, integrated lighting with turn signals and horn, and a 95% pre-assembled kit that makes unboxing and setup painless for first-time owners.

Is the Aipas M2 Pro for you?

If you’re shopping for an e-bike that can pull hard off the line, keep speed on long straights, and still tame broken pavement and fire roads, the M2 Pro fits the brief. The 110 Nm of torque gives you truck-like thrust for hills, while the 26” × 4.0” tires and dual suspension smooth out chatter, curbs, and washboard.

It’s built for bigger days, too. The 48V 17.5Ah battery is rated for up to 85 miles per charge under light assist. Expect far less if you lean on throttle or high PAS levels, but the capacity is generous enough for long urban loops or countryside rambles without range anxiety.

Who should look elsewhere? Lightweight purists, riders who prefer the ultra-natural feel of a torque sensor, and anyone in jurisdictions that strictly enforce Class 1/2/3 limits may want a different style of bike. The M2 Pro is heavy (around 90 lb), overbuilt, and unapologetically powerful. It excels when you want comfort and muscle more than nimble finesse.

In terms of budget, it sits in the mid-market for fat-tire, dual-suspension hub-drives. Considering the motor output, battery capacity, and the included lighting/controls, it represents strong value. It’s beginner-friendly to assemble and ride, though the speed and mass demand responsible use and some familiarity with bicycle basics.

What We Like About the Aipas M2 Pro

The motor and battery combo is the headliner. With 1,800W peak and 110 Nm claimed torque, the bike surges forward confidently. On steep neighborhood climbs where many hub-drives fade, the M2 Pro keeps momentum with less pedal thrashing. That power also makes headwinds and heavy cargo feel trivial.

Comfort is another big win. The adjustable, lockable front fork and rear shock take the edge off potholes and gravel chatter, while the 4.0” tires add a plush, floating sensation at the right pressures. The setup encourages exploring rougher shortcuts and unpaved connectors that you might avoid on a rigid or skinny-tire bike.

Braking is reassuring. With 180 mm dual disc rotors, lever feel is predictable and there’s enough bite for quick, drama-free slowdowns. The LCD cockpit is simple, the thumb controls are intuitive, and the integrated USB port is more useful than it sounds—topping up a phone or action camera on long rides is great. Night riding is better than average thanks to the bright headlight, taillight with brake flash, and built-in turn signals and horn.

Fit and finish are clean for the category. The semi-integrated battery looks tidy and claims IP65 water resistance, cable runs are reasonably managed, and the e-MTB frame feels stiff under load. Color options (black, grey, blue, green) add personality, and assembly really is straightforward because most of the hard work is done at the factory.

What We Don’t Like About the Aipas M2 Pro

Weight is the tax you pay for power and comfort. At ~90 lb, lifting the bike up stairs, onto a hitch rack, or through a narrow apartment corridor is a workout. The heft also means you should brake earlier at high speeds and respect the limits of fat tires on wet paint and loose-over-hard surfaces.

The drive system uses the common cadence-sensor approach, which brings a subtle on/off surge when assist engages. It’s not harsh, but it isn’t as “organic” as a mid-drive with a torque sensor. Experienced riders won’t mind; beginners may need a few rides to develop smooth cadence habits.

While the suspension is comfortable, it’s not a high-end trail fork/shock. Think comfort-oriented rather than aggressive singletrack tuning. The LCD is functional but basic, and the control pod’s buttons, while convenient, are small if you ride with thick winter gloves. Finally, be mindful of local e-bike regulations if you plan to use high PAS or throttle—unlocked top speeds can exceed Class 3 norms.

My take on the features: The spec sheet has genuine standouts—the motor, battery, fat-tire + suspension comfort, and safety lighting set the M2 Pro apart in daily use. The cadence-sensor drive won’t satisfy purists seeking the most natural pedal feel, but it’s predictable and easy for newcomers. The real-world strengths are hill performance, comfort on bad roads, and the confidence that comes from big brakes and big tires.

Ride Impressions

Acceleration & Hill Climbing. The bike pulls like a small scooter. From a stop, PAS 3–5 or throttle gives brisk acceleration without drama, and on steep neighborhood grades the hub keeps torque flowing. You still benefit from pedaling on the very steep stuff, but you won’t be grinding.

Handling & Stability. Fat tires plus a long wheelbase equal calm manners. The M2 Pro prefers sweeping lines to quick, flicky direction changes, and it rewards smooth inputs. On loose gravel the tires float predictably; lower pressures transform washboard roads from annoying to tolerable.

Comfort. Between the suspension and the air volume in the tires, you can ride longer without fatigue. The fork’s lockout helps when you want efficient paved-road pedaling, and unlocking it for curb hops or rough trails keeps wrists and back happy.

Braking. With 180 mm rotors, the levers deliver consistent bite and remain quiet when properly bedded. The big takeaway is planning: heavy bikes carry speed. Keep two-finger coverage on the levers at the top end and give yourself extra margin in the wet.

Cockpit & Controls. The display is basic but readable in sunlight. The control pod is intuitive—horn and lighting are always at thumb’s reach—and the USB port earns its keep on long days if you rely on your phone for navigation.

Noise & Vibration. The hub motor has the typical electric whir under load; otherwise the bike is quiet when bolts are torqued correctly and cables are tidied. Periodic checks keep it rattle-free.

Range. With mixed riding (PAS 2–3, occasional throttle, moderate hills), a practical single-charge range in the 30–55 mile window is realistic for many riders. Stick to PAS 1 on flat ground and you can stretch farther; high PAS or full-time throttle will shorten it significantly.

Fit & Sizing

The step-through-ish e-MTB frame is approachable for most adults. Aipas lists a minimum rider height of 58 inches and a high maximum load rating. In practice, the saddle and bar height accommodate a wide range, but shorter riders should check stand-over and reach before buying. If possible, measure your preferred saddle height and compare with the published “max/min seat to floor” numbers to be sure.

Everyday Use & Ownership

Commuting. The M2 Pro loves weekday duty. It shrugs off potholes, doesn’t mind winter grit, and the lights and turn signals help in traffic. If you commute at dawn or dusk, budget for a reflective jacket or pannier panels to complement the built-in lighting.

Errands. The motor makes city hills with a loaded backpack trivial. Add a rear rack and panniers to transform it into a capable car-replacement for short trips. The kickstand is sturdy enough for quick stops.

Security. Because of the weight, many riders will store this bike at ground level. A hardened U-lock through the frame and a secondary cable for wheels is smart. Bring the removable battery indoors when theft risk or temperature swings are concerns.

Maintenance. Hub-drives are straightforward to live with. Keep the chain clean, watch brake pad wear (heavy bikes eat pads faster), and check tire pressures weekly. Fat tires can hide slow leaks; a floor pump with a reliable gauge is essential.

Safety & Legal Considerations

Out of the box or unlocked, the bike’s speed potential can exceed Class 3 limits in many areas. Know your local e-bike rules before riding at higher speeds on shared paths.

The mass and speed also make good protective gear and rider discipline non-negotiable—gloves, bright apparel, and a properly rated helmet are smart investments.

Who Will Love the M2 Pro

• Riders who want serious hill power without moving to a mid-drive
• Anyone commuting on broken pavement, gravel, or snow who values comfort and stability
• Heavier riders or folks carrying cargo who benefit from high torque and big brakes
• New owners seeking an easy assembly and a feature-complete package with lighting and signals

Who Should Consider Alternatives

• Minimalists who want a sub-60 lb bike for apartment carry
• Riders who prize a torque-sensor, mid-drive feel above all else
• People in jurisdictions with strict Class 1/2/3 enforcement who won’t use higher speeds

Tips to Get the Best From the M2 Pro

1. Dial tire pressure to terrain. Try the mid-teens (psi) on gravel and 20–25 psi on pavement, adjusted for rider weight, to balance comfort, grip, and efficiency.
2. Use PAS smartly. PAS 2–3 delivers a smooth blend of help and range. Save PAS 5 and throttle for short bursts or steep hills.
3. Set the fork sag. Matching air/coil preload and lockout to your weight improves both comfort and steering precision.
4. Bed in the brakes. A few medium-hard stops from 15–20 mph seats pads to rotors for quieter, stronger braking.
5. Keep the battery happy. Store between 20–80% for long life and avoid leaving it at 100% for weeks.

Final Breakdown

9.1 / 10

The Aipas M2 Pro delivers what most riders actually want from a fat-tire e-bike: abundant power, comfortable suspension, confident braking, and real-world practicality. It’s a heavy, muscular machine that feels unfazed by hills, potholes, and gravel connectors. The big battery keeps you out longer; the lighting and signals make night rides less stressful; and day-to-day, it’s easy to live with.

It isn’t the lightest or the most refined in pedal feel, and you’ll want to respect the speed and mass it can generate. But judged as a powerful, value-packed fat-tire e-MTB for commuting and adventure, the M2 Pro earns a strong recommendation. If your riding includes steep neighborhoods, rough roads, and weekend exploring—and you want an e-bike that simply refuses to bog down—this one belongs at the top of your list.
