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 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.
This hub is spaced to 170mm w/ 15mm disc-offset for Fatbike rear wheels.
We can also space it to 190mm for use without a disc brake
If you have a bike that uses a rear disc brake & 190mm spacing, we can include disc rotor shims and screws to help line the disc up for 15mm disc offset.
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. Top speed is 28MPH! 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): 500-1000w (EBK 22amp controller)
Top Speed: Approx. 26 MPH @48v 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
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: You can find your wheel size written on your tire. Available size options for this conversion kit are: 20", and 26". The 20" rim is 54mm wide and the 26" rim is 74mm wide. These rims are suitable for 3" - 4" width tires.
Battery Choice: We offer 3 battery packs for this kit - the 9ah Li-Ion Blue battery is the lightest and smallest, at just 5.8lbs. 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||5.8lbs||10-22||Battery bag with velcro straps (included, rack not included)||Base Cost|
|48v 10ah||9.7lbs||12-26||Rear Rack (included)||+$230|
|48v 20ah||14lbs||20-44||Battery bag with velcro straps (included, rack not included)||+$380|
Front vs. Rear Wheel: We recommend rears for most conversions.
A common misconception is that 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 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.
Note: our kits include parts to fit a wide variety of bikes, but do not fit every bike without modification or extra parts. Our representatives are available to help with compatibility questions and make recommendations on additional parts that you may need.
Shipping Note: Li-ion batteries are shipped separately from electric bike kits. Li-ion battery packs are shipped via UPS Hazmat and require a signature for delivery. You may receive your kit, battery and possibly the battery rack (if applicable), on separate days.
