E-BikeKit™ Rear 500w Geared Hub Motor Conversion Kit for Fatbikes with 48 Volt Li-ion Battery Pack and Charger.
The E-BikeKit 500-1000w geared conversion kit is powered by an internal 5:1 planetary gear hub motor with a clutch. The clutch in the geared motor offers zero drag when pedaling and not engaging battery power. This motor is more efficient, resulting in increased range (especially with "start/stop" riding), has more starting torque, and has greater hill-climbing ability than a direct drive motor of equal power rating. The motor is also smaller in diameter for increased stealth and 3.4 lbs lighter than the 500w direct drive.
Who's it for? This premium electric bike conversion kit system is for those that want the best of the best in performance, efficiency, weight, stealth, and speed. The top speed is 28 MPH! There is a 300 lbs total load limit so if you plan on more than that, look to a heavy-duty system.
This kit uses a motor designed especially for fat bikes. It provides 170 - 190mm OLD rear spacing (using spacer-washers) and 15mm disc offset (170mm) - add 10mm disc rotor spacer (not included) and extra-long screws for 15mm disc-offset with 190mm.
The chain line is 64mm. Add our freewheel spacerfor a 75mm chain line.

Lithium batteries provide a high level of performance for the duration of each discharge (unlike seal lead-acid where performance is diminished 1:1 as the pack is emptied). Lithium batteries have a much higher power-to-weight ratio than lead-acid and 5-8 times the number of charge cycles (how many times a rechargeable battery can be charged from 0-100%). The lithium option costs more initially, but over time, the "cost-per-cycle" is about half the cost of lead-acid. Lithium packs also require less care as they can be left partially charged, and do not require immediate charging after each use. All batteries MUST be properly cared for during storage.
Choosing Your Wheel Size: Available size options for this conversion kit are 20in, and 26in. You can find your wheel size written on the sidewall of the tire. The 20in rim is 54mm wide and the 26in rim is 74mm wide. These rims are suitable for 3-4 inch width tires.
Front vs Rear Wheel: We recommend rears for most conversions. A common misconception is that the front wheel conversions are easier. It is our professional opinion that there are two legitimate reasons to use a front wheel hub motor:
1) You want a true two-wheeled drive
2) You have an internal rear hub shifter
If neither applies to your conversion, a rear wheel conversion is likely a better choice.
Battery Choice: We offer 3 battery packs for this kit - the 9Ah li-ion blue battery is the lightest and smallest, at just 5.8 lbs. The 20Ah li-ion blue battery is the longest-lasting, with a 20-44 mile range. The 10Ah li-ion aluminum case battery sports a rugged enclosure, carrying handle, and locks in place with a key.
48v 9Ah Bag Battery
- Range: 9-18 Miles
- Price: $1,382.00
This e-bike battery is a lightweight and easy-to-carry pack. Two of these packs will fit into one canvas battery bag (included) nicely, offering the option of taking one or two of these depending on your range needs. You do have to connect them one at a time as needed; same for charging.
** It is common to carry two 48v 9Ah batteries in the same canvas bag in order to double your range. However, these batteries can not be used in parallel with one another. In other words, you would have to physically unplug one, in order to use the other. **
