E-BikeKit™ Rear 500w Geared Hub Motor Conversion Kit for Fatbikes
with 36 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 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 3.4lbs 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 and stealth. There is a 300lb total load limit so if you plan on more than that, look to a heavy-duty system.
This kit uses a motor designed specially for fatbikes. 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.
Chainline is 64mm. Add our freewheel spacer for 75mm chainline.
Note: geared 500w “Performance” Motors feature an internal clutch to reduce drag, and can not read speed or mileage when not in use.
Watts (Nominal/Peak): 500-750w (EBK 22amp controller)
Top Speed: Approx. 20 MPH @36v in 26" wheel
Range: 10-44 Miles *(see battery chart)
Charge Time: 3-5hrs (0-100%) (depending on battery choice)
Weight: 21lbs (9.5kgs)
Stealth Factor: High
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
-9ah Li-Ion Shrink Wrapped battery is the lightest and smallest, at just 5.8lbs. (Standard)
-20ah Li-Ion Shrink Wrapped battery is the longest lasting, with a 20-44 mile range. (+$400)
-10ah Li-Ion Aluminum Case battery sports a rugged enclosure, carrying handle, and locks in place with a key. (+$140)
