Aostirmotor S18-1500W Full-Suspension Fat Tire Electric Bike

The Aostirmotor S18-1500W stands out because it has a motor twice as powerful as most e-bikes, delivering 1500 watts of power that’s perfect if you’re heavier than 225 lbs or need to haul heavy loads. It offers a comfy ride with a slight forward lean typical of mountain bikes, and you can pedal manually with its 7-speed Shimano drivetrain or switch between five pedal assist levels and a twist throttle to get the perfect balance of human and electric power.

Pros:

  • Powerful 1500W motor

  • 48V/15Ah battery offers about 36 miles per charge

Cons:

  • Forward riding posture can be uncomfortable

  • 36-mile range might fall short for longer rides

The S18 shares a lot with the S18-1500W, like the full-suspension frame and Samsung-cell battery, but it comes with a 750W motor instead, giving you a top assist speed of 28 mph. It’s a solid, comfortable ride thanks to its suspension, making it a great all-terrain option for those who want power without going overboard.

Pros:

  • Strong 750W motor

  • Comfortable full-suspension frame

  • Decent battery range

Cons:

If you need something compact and easy to store, the A20’s folding frame and handlebar make it super portable—ideal for RVers, students, or outdoor fans. It’s surprisingly powerful for its price with a 500W motor, 5 pedal assist levels, and a twist throttle, plus it has a 7-speed Shimano drivetrain and reliable disc brakes, though it’s best for shorter, casual rides.

Pros:

  • Convenient folding design

  • Affordable price for features

Cons:

  • Not great for long rides

  • Lacks some advanced features found in pricier models

Aostirmotor Storm 750W Fat Tire Electric Bike

Built tough with a magnesium alloy frame, the Storm is lightweight yet durable and great for city streets or light trails. It packs a 750W motor with a 48V/12.5Ah battery that fits nicely on the downtube, plus a 7-speed Shimano drivetrain. You get a simple but effective pedal-assist system and twist throttle, making it a no-nonsense option for riders who want power and durability without breaking the bank.

Pros:

  • Strong, lightweight magnesium alloy frame

  • Versatile 7-speed Shimano gears

Cons:

  • Smaller 12.5Ah battery limits range

  • Missing some high-end features

The A30 is perfect if you want off-road ability but also need a foldable, easy-to-transport bike. It’s got a 750W rear motor, a removable seat-tube battery, and multiple riding modes like 5-level pedal assist and a twist throttle. With 7-speed gears and solid disc brakes, it handles urban and trail rides well, but its 15-35 mile range means it’s best for shorter trips, and new riders might need time to get used to the throttle.

Pros:

  • Foldable and portable design
