Aipas is aiming squarely at the “big motor + fat tires + value pricing” corner of the market—bikes that promise strong acceleration, comfort on rough roads, and enough range for longer weekend rides.
My ranking criteria is simple: best match for real riders, safest overall package for the price, least buyer regret, and clearest “who it’s for / who should skip.”
Quick Verdict
Best overall pick: Aipas M2 Pro — the most “do-it-all” fat-tire option here for mixed pavement + light off-road, assuming you’re comfortable with a big, fast bike.
Best value / easiest to live with: Aipas M1 Pro — the step-thru frame is a real quality-of-life win for everyday riders.
Who should buy from this list: riders who want a powerful, upright e-bike for commuting, weekend exploring, and rougher roads without paying premium-brand prices.
Who may want to look elsewhere: anyone who needs a lighter bike, wants a true bicycle-like pedal feel (torque sensor), or prioritizes higher-end brakes and suspension tuning.
Top Picks at a Glance
| Model | Best for | Key strength | Main drawback |
|---|---|---|---|
| Aipas M2 Pro | Mixed terrain + stronger hills | Big power claims + fat-tire stability | Likely heavy; 36 mph claims raise legal/safety questions |
| Aipas M1 Pro | Comfort + easy mounting | Step-thru convenience + dual suspension | Mechanical discs on a fast, heavy bike can be a weak point |
| Aipas F3 (Folding) | Storage + RV/trunk life | Folding design + utility basket | Smaller battery; small wheels feel less stable at speed |
Product Reviews
1) Aipas M2 Pro — Best Overall
Why it’s our top pick
If you want one Aipas that most people can buy without immediately wishing they chose a different style, the M2 Pro makes the most sense. It’s positioned like a classic fat-tire eMTB-style commuter: stable stance, “go anywhere” tires, suspension up front, and a power claim strong enough to handle real-world stop-and-go or mild trails.
Key features
- High peak-power claim (1800W) + 110Nm claimed torque for punchy starts and climbing.
- 26″ x 4.0″ fat tires for comfort and traction on broken pavement, gravel, and loose surfaces.
- Dual suspension setup (front fork is adjustable/lockable per your details).
- USB port + multiple riding modes including cruise and walk assist.
What I like
- Confidence on imperfect roads. A fat tire platform usually smooths out the chatter that makes rigid commuters feel harsh—especially if your routes include potholes, curb cuts, or sandy shoulders.
- A calmer ride at “normal fast” speeds. Most riders cruise in the teens to low 20s mph. That’s where fat tires and a longer, heavier bike often feel planted.
- Useful commuter touches. Lights and a horn are practical if you’re mixing bike lanes, parking lots, and neighborhood streets.
What could be better
- 36 mph claimed speed is a real buyer-risk. In many places, that’s beyond typical e-bike class limits. Even if the bike can do it, you may not want to ride that fast on fat tires with entry-level suspension and braking.
- Likely heavy and bulky. Most 26×4 fat-tire bikes with suspension and a big battery are not “carry up stairs” machines.
- Brake expectations. The listing calls out disc brakes and strong braking performance, but without confirmed brake type (hydraulic vs mechanical), I’d assume you may need to upgrade pads, adjust often, or plan a future brake upgrade if you ride fast or hilly routes.
Pros & Cons
| Pros | Cons |
|---|---|
| Stable “all-roads” feel from 26×4 tires | Likely heavy—storage and lifting can be a pain |
| Strong claimed power for starts and hills | 36 mph claims can be legally messy and safety-risky |
| Suspension helps comfort on rough routes | Budget suspension may feel bouncy/under-damped |
| Useful modes (walk/cruise) + USB charging | Braking may be the limiting factor at higher speeds |
Who this bike is best for
- Riders who want one bike for commuting + weekend exploring on mixed surfaces.
- Heavier riders or hilly-area riders who want more headroom in motor output (even if you don’t chase top speed).
- Anyone who prefers a stable, upright, “big bike” feel over nimble and lightweight.
Who should skip this bike
- You need to carry the bike up stairs, lift it onto racks often, or store it in tight apartments.
- You want a natural bicycle pedaling feel (torque sensor bikes usually win there).
- You plan to ride fast daily but don’t want to invest in brake upgrades and frequent checks.
2) Aipas M1 Pro — Best for Comfort + Easy Mounting (Step-Thru)
Why it ranks #2
The M1 Pro is the “easy to live with” pick. A step-thru frame genuinely changes day-to-day ownership: getting on/off is simpler, stops feel less awkward, and it’s friendlier for riders wearing work clothes or dealing with limited mobility.
Key features
- Step-thru frame with a very broad claimed rider-height range.
- 48V 17.5Ah removable battery with a wide claimed range band.
- Dual suspension: lockable front fork + rear shock.
- 180mm mechanical disc brakes (explicitly stated).
What I like
- Step-thru isn’t just convenience—it’s confidence. In traffic or frequent stops, being able to step off cleanly matters.
- Comfort-forward setup. Fat tires + suspension + upright geometry usually equals “less beat up” after longer rides on cracked pavement.
- Simple device charging. USB on the controller is a small thing that’s actually useful on longer rides.
What could be better
- Mechanical disc brakes on a “fast fat bike” setup is a mismatch risk. Mechanical discs can stop well when tuned, but they usually require more frequent adjustment and stronger lever pull—especially if the bike is heavy and you ride hills.
- Torque/cadence feel is unknown. If this uses cadence-based assist (common at this price point), starts can feel more “on/off” than torque-sensor bikes.
- Range claims are broad. A claimed “up to 85 miles” is typically an ideal-case number. If you ride fast, ride hills, or use throttle often, expect materially less.
Pros & Cons
| Pros | Cons |
|---|---|
| Step-thru frame = easiest daily usability | Mechanical brakes may need frequent tuning |
| Comfortable platform for rough streets | Likely heavy and large (fat tires + suspension) |
| Big battery capacity on paper | Real-world range depends heavily on speed and terrain |
| Practical display + USB charging | Not the most “bike-like” feel if cadence-based PAS |
Who this bike is best for
- Riders who prioritize easy mounting, comfort, and casual confidence.
- Commuters on rough roads who want cushion and stability more than nimble handling.
- Anyone planning moderate speeds and smoother riding, not constant high-speed runs.
Who should skip this bike
- You live in a very hilly area and plan fast descents—consider bikes with stronger braking systems.
- You want something light, apartment-friendly, or easy to load on a rack.
- You’re sensitive to “jumpy” assist behavior and really want torque-sensor smoothness.
3) Aipas F3 — Best Folding Option for Storage + Trunk/RV Use
Why it’s here
If your #1 problem is storage, not trail performance, the F3 is the only model in your list that solves that. Folding e-bikes are almost always about where the bike lives as much as how it rides.
Key features
- Folding frame + rear basket for errands and RV/trunk life.
- 20″ x 3.0 tires (smaller than the 26×4 bikes, but still wider than standard commuter tires).
- 48V 12.8Ah removable battery (624Wh listed).
- Full suspension design (complex multi-link structure claimed).
What I like
- The folding advantage is real. If you’ll actually bring the bike more often because it fits your trunk or RV bay, that beats a “better” bike that stays in the garage.
- Utility-ready out of the box. A rear basket is simple, but it’s immediately useful for groceries, locks, and small cargo.
- Moderate-speed comfort. Wide-ish tires plus suspension generally makes neighborhood cruising pleasant.
What could be better
- Smaller wheels feel twitchier at speed. A 20″ folding bike is rarely the best choice for high-speed stability. If you’re chasing speed, this isn’t the safest platform.
- Smaller battery than the M1/M2 Pro. That’s not “bad”—it’s just a reality check on range if you ride fast or rely on throttle.
- More moving parts = more maintenance potential. Folding hinges and complex suspension linkages can mean more bolts to check and more places for squeaks over time.
Pros & Cons
| Pros | Cons |
|---|---|
| Folds for storage, trunk, RV | Less stable at high speed than 26″ bikes |
| Practical rear basket for errands | Smaller battery = less range headroom |
| Comfortable tires + suspension for casual riding | More joints/hinges = more checks and upkeep |
| Easier to fit in small living spaces | Not ideal for tall riders who need roomy fit |
Who this bike is best for
- Riders with limited space: apartments, condos, RV travelers, or anyone storing a bike in a car trunk.
- Short-to-average commutes and errands where portability matters more than outright performance.
- Riders who prefer moderate speeds and simple utility.
Who should skip this bike
- You want a stable, fast commuter for long open-road runs.
- You’re tall and prefer a full-size cockpit feel.
- You want the simplest long-term maintenance setup (folding + suspension adds complexity).
What to Look for When Buying Aipas Electric Bikes
1) Don’t buy a “speed number”—buy a safe cruising setup
A claimed 36 mph is attention-grabbing, but most riders are happiest (and safest) cruising well below that. What matters more:
- predictable throttle behavior
- smooth PAS steps at low speeds
- braking confidence and control
2) Brakes matter more on heavy fat-tire bikes
If you’re buying a big, fast platform, prioritize:
- easy adjustability and strong stopping power
- pad availability
- consistent lever feel on long descents
Even “good” brakes can feel mediocre if the bike is heavy and you ride aggressively.
3) Range is mostly about how you ride
Real-world range drops quickly when you combine:
- high speeds
- throttle-heavy riding
- hills + wind
- low tire pressure
A big battery helps, but it doesn’t rewrite physics.
4) Think about where the bike lives
Before you buy, answer:
- Can I roll it in without stairs?
- Do I need to lift it onto a rack?
- Do I have room to park it safely and charge it?
5) Suspension on value e-bikes is about comfort, not downhill performance
Most budget “dual suspension” setups are tuned for smoothing bumps, not aggressive trail riding. If you want real trail capability, geometry, fork quality, and brake heat management become the limiting factors.
Final Verdict — The Best Aipas Electric Bike
If you want the most balanced option from your list, the Aipas M2 Pro is the best overall pick for mixed-terrain riding—as long as you prioritize sensible speeds and do routine safety checks (especially braking and fasteners).
If you value comfort and easy daily use more than anything else, the Aipas M1 Pro is the friendliest bike to live with thanks to the step-thru frame.
If storage is your main constraint, the Aipas F3 is the practical choice—but it’s best treated as a portable utility e-bike, not a high-speed machine.
FAQ
Is a 36 mph e-bike street legal in the USA?
Often not as a standard e-bike class. Laws vary by state/city—verify local rules before buying or unlocking higher speeds.
Which model is best for hills?
The M2 Pro and M1 Pro (higher claimed torque and big fat tires) are better suited than a small-wheel folder, assuming gearing and tuning are decent.
Which is easiest to mount and ride casually?
The M1 Pro step-thru frame is typically the easiest for frequent stops and relaxed riding.
Will fat tires make it harder to pedal without assist?
Yes. Fat tires add rolling resistance. If you care about pedaling efficiency with the motor off, consider a lighter, narrower-tire commuter style.
Do folding e-bikes require more maintenance?
Usually yes—hinges, clamps, and extra joints mean more bolts to inspect and tighten over time.
What should I check after assembly and the first few rides?
Brake adjustment, rotor rub, axle tightness, handlebar alignment, hinge/clamp tightness (folding bikes), and tire pressure.
Is “full suspension” necessary for commuting?
Not necessary, but it can improve comfort on rough roads. The trade-off is usually added weight and more parts to maintain.
