Finding the best electric bikes with 17 5ah requires careful comparison of key specifications. We analyzed 5 models ranked by their published data. The Aipas M1 Pro Step-Thru Fat Tire E-Bike leads this list because its 1800W motor and full suspension handle off-road trails and easy step-through access effectively. All picks are based strictly on the specifications published on the listings. This guide helps you decide which bike matches your terrain needs and frame preferences.
Match motor power to your weight
Most bikes here share 1800W motors, but two PUJH models offer 2000W. If you carry heavy loads or ride steep inclines, the extra torque helps. Otherwise, the standard 1800W provides ample power for off-road trails. All models use 48V batteries and full suspension for comfort.

How We Selected These Bikes
We identified these 5 electric bikes by scanning Amazon listings for the specific battery capacity of 17.5Ah. We verified this spec in the product title or feature list to ensure accuracy. Only one size or variant from each product family is included to keep the comparison clear and focused on the shared power source. We did not handle these units physically. All details rely on published specifications and feature lists from the seller. The products are ordered by availability first, then by overall rating weighted by review count, and finally by how well their specs meet our criteria. This method helps you find reliable options with the exact energy storage you need for longer rides. We do not test these bikes ourselves.
How to Choose the Right 17.5Ah E-Bike
Check the frame type
Decide if you need a step-through or step-over frame. The Aipas M1 Pro offers a step-through design, making it easier to mount and dismount, which is helpful for riders who prefer low-step access. The LEONX M2 Pro uses a traditional step-over frame. Your choice depends on your mobility needs and comfort preferences when getting on and off the bike during stops.
Compare motor power
Most models in this group feature 1800W motors, but the PUJH variants offer 2000W options. Higher wattage provides more torque for steep inclines and heavy loads. If you carry significant weight or ride on challenging terrain, the 2000W motor may offer better performance. For standard off-road trails, the 1800W specification is generally sufficient and consistent across most brands in this list.
Look at tire size
Tire width affects stability and comfort on rough ground. Fat tires are common here, providing better traction on loose surfaces. The Aipas and LEONX models use 26-inch width tires. The PUJH bikes feature a 27-inch width. Wider tires generally offer more stability and shock absorption. You should choose the width that matches the terrain you plan to ride on most frequently.
Review suspension setup
Full suspension systems absorb bumps and improve control on uneven trails. The Aipas M1 Pro, LEONX M2 Pro, and the standard Aipas M1/M2 Pro all include full suspension. This setup reduces fatigue on long rides. The PUJH models are listed as suitable for off-road use but do not explicitly list suspension details in their primary attributes. Check the full spec sheet if suspension is a priority for your comfort.
Assess bike weight
Weight impacts portability and handling. The PUJH 29-Inch models are notably lighter at 70 pounds. The Aipas M1 Pro weighs 88 pounds, while the LEONX M2 Pro and other Aipas variants weigh 90 pounds. Heavier bikes may be more stable but harder to lift or transport. Consider how often you need to move the bike manually. Lighter frames offer easier handling for storage and transport.
Frequently asked questions
What is the maximum weight capacity for these e-bikes?
The data does not list specific weight limits for any of the five models. You should check the manufacturer’s manual for the maximum rider and cargo weight. Heavier frames like the LEONX M2 Pro weigh 90 pounds, which may suggest a robust build, but official limits are not provided in the specs.
Do these bikes come with hydraulic brakes?
The specifications do not confirm hydraulic brakes for any model. The Aipas M1/M2 Pro is explicitly noted to have mechanical brakes. The LEONX M2 Pro lists disc brakes but does not specify if they are hydraulic. You should verify the brake type with the seller if low maintenance is a priority.
Can I remove the battery from these e-bikes?
Yes, at least two models feature removable batteries. The Aipas M1/M2 Pro and the PUJH PU1 both list removable battery as a key feature. This allows you to charge the power source indoors or separately without transporting the entire heavy bike. The other models do not specify this capability in the provided data.
How tall is the frame on these electric bikes?
All listed models share a consistent height specification of 44 inches. This measurement likely refers to the overall bike height or standover height. The Aipas M1 Pro and LEONX M2 Pro both list 44 inches. This uniform height suggests a standard geometry across these fat tire designs.
What is the total weight of the heaviest bike on the list?
The heaviest models listed are the LEONX M2 Pro and the Aipas M1/M2 Pro, both weighing 90 pounds. The Aipas M1 Pro is slightly lighter at 88 pounds. The PUJH models are lighter, weighing 70 pounds. These weights reflect the robust construction needed for fat tires and full suspension systems.
Are these bikes suitable for riders under 5 feet tall?
The data does not provide rider height recommendations. However, the frame dimensions are uniform, with a width of 26 to 27 inches and a length of 72 to 80 inches. The Aipas M1 Pro offers a step-through frame, which may accommodate shorter riders more easily than the step-over designs of the LEONX M2 Pro.
Does the 17.5Ah battery provide a specific mileage range?
The provided specifications do not list exact mileage ranges for any model. The Aipas M1 Pro verdict mentions an 85-mile range, but this is not in the specs table. You should assume range varies based on terrain and assist level. The 48V 17.5Ah capacity is the consistent energy source across all five bikes.
What tire size do these fat tire e-bikes use?
The PUJH models specify 29-inch wheel sizes. The Aipas M1/M2 Pro lists 26-inch wheels. The LEONX M2 Pro and Aipas M1 Pro do not explicitly state wheel size in the specs, but their width is 26 inches. All models utilize fat tires for off-road traction and stability on varied terrain.
