E-BikeKit Rear 500w Direct-Drive Hub Motor Conversion Kit with 48 Volt Li-ion Battery Pack and Charger.

This premium electric bike conversion kit system is for riders that require the increased durability of a direct-drive motor for heavier loads and the long term reliability of a lithium battery. The direct-drive hub motor used in this conversion kit system is for heavier applications and a MUST for any total load (bike+rider+cargo) of 300lbs or more. This system pairs the heavy-duty motor with a 48v battery pack with a 20 mph top speed for increased torque.

Direct-drive motors are strong, durable, and long-lasting due to zero internal friction. Some lower quality or larger direct-drive motors have resistance, but that should not be a concern with this E-BikeKit direct-drive hub motor.

System Specs:
Watts: (Nominal/Peak) 500-1000w (EBK 22Amp controller)
Top Speed: Approx. 20 MPH @48v in 26" wheel
Range: 9-42 Miles *(see battery chart)
Charge Time: 2.5hrs (0-100%)
Weight: 24lbs (11kgs)
Performance: High
Efficiency: Medium
Stealth Factor: Low

Li-ion 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). Li-ion 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 li-ion option costs more initially, but over time, the "cost-per-cycle" is about half the cost of lead-acid. Li-ion 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.


Battery Choice: We offer 3 battery packs for this kit - the 9Ah li-ion shrink wrapped battery is the lightest and smallest, at just 5.8lbs. The 20Ah li-ion shrink wrapped battery is the longest-lasting, with a 20-44 mile range.

Choosing Your Wheel Size: 
You can find your wheel size written on your tire. Available size options for this conversion kit are: 16", 20", 24", 26", 700c and 29er. Acceptable tire widths for the E-BikeKit rims: 1.15" (29mm) - 2.25" (57mm).

Freewheel choice and OLD spacing: Our motors are intended for a 7-speed freewheel and provide 135mm OLD (dropout) spacing with a 7-speed freewheel and 15mm disc-offset.

When using an 8, 9, or 10-speed freewheel, this will increase the OLD by about 3.5mm per speed. When we assemble the motor here, we will dish and space it correctly to fit this. To install the wider wheel, you may need to spread the dropouts of the bike open in order to fit.

If you are not using disc brakes, so don't need the 15mm disc-offset, we can reconfigure the spacing to fit 135mm in many cases.
