Description

E-BikeKit Rear 500w Geared Hub Motor Conversion Kit for Fat Bikes with 36v 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, and stealth. There is a 300 lbs total load limit so if you plan on more than that, look to a heavy-duty system.

This kit uses a motor designed especially for fat bikes. 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.

The chain line is 64mm. Add our freewheel spacer for a 75mm chain line.

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.

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: 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.

Front vs. Rear Wheel: We recommend rears for most conversions. A common misconception is those 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.
