Introduction:
Since the invention of bicycles, manufacturers have continuously innovated to create more convenient models. This led to the development of folding bicycles, which later inspired the rise of folding electric bikes. Over time, this category has evolved and matured, offering riders more versatility and convenience.
Aipas® has been at the forefront of this innovation, launching two classic folding e-bikes: the A2 and A4. Let’s take a closer look at their differences to help you decide which one suits you best.
Aipas® A2 Elite Ebike & Aipas®A4 Gentry Ebike
The A2 was Aipas’ first flagship model, refined over two years to ensure outstanding quality and reliability. Following its success, Aipas introduced the A4, a lightweight folding e-bike that offers an alternative choice while maintaining exceptional quality. Both models cater to different riding preferences and needs.
Frame Design
Both the A2 and A4 feature a step-through frame design for easy mounting and dismounting. However, there is a key difference:
- A2 houses its battery inside the frame, making the frame slightly larger and providing enhanced stability during rides.
- A4 has an external battery, resulting in a more compact frame, which enhances maneuverability and portability.
Size & Weight
- Dimensions (Unfolded): Both A2 and A4 measure 66” x 24” x 44”.
- Weight: A2 weighs 59 lbs, while A4 is 55 lbs, making A4 the lighter option.
-
Folded Dimensions:
- A2: 33” x 20” x 31”
- A4: 32” x 22” x 28”
From a portability perspective, A4 is more compact and easier to carry.
Braking System
Both A2 and A4 are equipped with mechanical disc brakes, which provide reliable stopping power. However, the key difference lies in the brake rotor size:
- A2 uses 180mm rotors, which offer greater braking force and better heat dissipation, improving overall braking performance.
- A4 uses 160mm rotors, which are still effective but slightly less powerful in extreme conditions.
Due to its larger brake rotors, A2 provides superior braking performance.
Battery
- A2 Battery: Samsung 48V 11Ah, IP65 waterproof, UL2271 certified
- A4 Battery: Samsung 48V 12.8Ah, IP65 waterproof, UL2271 certified
Both models support an optional 14Ah battery upgrade, extending their range to 76 miles. Their batteries meet high safety and durability standards, exceeding most market alternatives.
A4 has a larger battery capacity, providing longer rides between charges.
Motor & Torque
- A2: 750W motor, 55Nm torque
- A4: 1000W motor, 78Nm torque
Both models can unlock the speed limit to reach 28 mph. In real-world tests, A2 has exceeded 30 mph (see video).
While A4 has stronger specs on paper, A2’s finely tuned motor allows it to achieve similar speeds. This makes their performance quite comparable.
Final Thoughts
After multiple comparisons, we can summarize:
- A2 is ideal for beginners looking for a high-quality entry-level folding e-bike.
- A4 is suited for riders who prioritize portability and a more powerful ride experience.
In most cases, the difference between A2 and A4 is subtle, as both are exceptional choices. The goal of this comparison is not to declare a "better" model, but to help you identify which bike aligns with your personal preferences.
After all, the best choice is not about what’s objectively superior—it’s about what you truly enjoy riding. 🚴♂️✨
