E-BikeKit Rear 500w Geared Hub Motor Conversion Kit 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.

System Specs:
Watts (Nominal/Peak): 500-1000w (EBK 22Amp Controller)
Top Speed: Approx. 26 Mph @ 48v in 26" Wheel
Range: 10-44 Miles (Based on rider's weight, input, and terrain contingent)
Charge Time: 3-5 Hours (Charged from 0-100% and depending on battery choice)
Weight: 21 lbs (9.5 kgs)
Performance: High
Efficiency: High
Stealth Factor: High

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.

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 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: $1,360.00
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. **

Price: $1,580.00
