Whether you want to electrify a bike you already own or skip the retrofit and ride a fat-tire ebike out of the gate, the decision usually centers on motor power, wheel size, and how much work you want to do. The four options here range from a $183.20 26-inch rear wheel kit to a $695.74 72V 3000W motor wheel, with a complete ebike and a 1500W 20-inch kit in between.
Quick Take
- The **URLIFE 20"*3.0 Fat Tire Electric Bicycle** is the complete-bicycle option if you want a finished ebike rather than a conversion project.
- The 72V 3000W rear hub motor wheel is the highest-power fat-tire retrofit, built for riders who want serious torque.
- The 26-inch rear wheel kit is the easiest entry point, but you will need to provide a battery.
- The compact rear wheel kit adds more power with an LCD display and PAS sensor for smaller builds.

Product notes
URLIFE 20"*3.0 Fat Tire Electric Bicycle
The URLIFE is the only full bicycle in this lineup. It has a 48V 13Ah removable battery, a 1000W peak brushless motor, and a 7-speed drivetrain, so it works as an everyday rideable ebike rather than a parts set. The front fork suspension, fat 20-inch tires, LCD display, and dual lighting make it a sensible pick for off-road or mixed-terrain rides. The trade-off is obvious: you are not converting an existing bike, and the wheel size is fixed by the 20"*3.0 fat tire setup. If your goal is to transform a bike you already own, this option does not offer that flexibility.
72V 3000W Ebike Bicycle Conversion Kit4.0 Rear Hub Motor Wheel
The strongest motor option here is this 3000W rear hub motor wheel with a 72V lithium-ion system. It comes as a fat-tire wheel that can be used in 20-inch, 24-inch, or 26-inch bikes, and it is compatible with a wide range of e-bike styles, from city and mountain to cargo and folding bikes. It also carries a 2-year manufacturer warranty. The practical limitation is that the motor draws a lot of current; the guidance keeps maximum current at 50A and suggests pedal-assist on uphill climbs instead of pure electric to avoid controller damage. That makes it a powerful but care-intensive upgrade.
26" Rear Wheel Electric Bicycle EBike Conversion Kit Hub Motor Cycling 48V 1000W
This is the lowest price in the group. It pairs a 26-inch rear wheel with a 1000W brushless toothless hub motor and a 48V system, with motor efficiency rated above 80%. Construction materials include aluminum, iron, copper, and rubber butyl, and the kit is designed for electric bike use. The catch is that the battery is not included; you need a 48V 17-20Ah lithium battery or a lead-acid battery to make it run. If you already have a 26-inch bike and want an affordable way to start electrifying it, this kit gives you the core wheel and motor, leaving battery selection to you.
20in Rear Wheel 48V 1500W Electric Bicycle Ebike Conversion Kit Hub Motor LCD
For a 20-inch build, this 1500W kit slots between the 1000W and 3000W options. It includes an LCD display, a 48V 1500W controller, power-off brake levers, and a PAS sensor that makes pedaling and hill climbs easier. The motor is rated above 82% efficiency and is designed to run quietly. Assembly is required, and like the 26-inch kit, the battery is not included; this one is set up for a 48V 20A lithium battery. It is a natural fit for folding bikes or compact commuters where the 20-inch rear wheel is already the format you want.
Final Recommendation by Use Case
- If you want a simple conversion on a 26-inch bike: go with the 26-inch rear wheel kit and pair it with a compatible 48V battery.
- If you ride a 20-inch or folding bike and want more power: the 20-inch rear wheel kit with LCD display is the stronger fit.
- If you want maximum torque from a fat-tire rear wheel: the 72V 3000W rear hub motor wheel is built for that, but be ready for higher current draw and careful uphill riding.
- If you prefer a complete bicycle over a conversion project: the URLIFE 20"*3.0 fat tire ebike is the full-bike choice.
