E-BikeKit Front 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 300 lbs or more. This system pairs the heavy-duty motor with a 48v battery pack for increased torque and an 18 mph top speed.

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. 18 Mph @ 48v in 20in Wheel
Range: 9-42 Miles
Charge Time: 2.5 Hours (From 0-100% and depending on the battery)
Weight: 24 lbs (10.88 kgs)
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 5.8 lbs. The 20Ah li-ion shrink-wrapped battery is the longest-lasting, with a 19-42 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: $1,254.00

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. **

48v 10Ah w/ 2-Tier Rack

• Range: 10-20 Miles
• Price: $1,478.00

This li-ion e-bike battery offers a nice finished look plus a locking mechanism for securing the battery in the middle section of an included 2-tiered rack. The top of the rack remains clear and available. 

48v 20Ah Bag Battery

• Price: $1,690.00
