E-BikeKit™ Rear 500w Direct-Drive Hub Motor Conversion Kit
with 36 Volt or 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 lithum 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 300lbs or more. This system pairs the heavy-duty motor with a 36v battery pack with a top speed of 14MPH or 48v battery pack with a 20MPH top speed for increased torque.
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.
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 weight to power 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: 16", 20", 24", 26", 700c & 29er. Acceptable tire widths for the E-BikeKit rims: 1.15"(29mm) - 2.25"(57mm).
Freewheel choice and OLD spacing: Our motors are intended for a 7-speed freewheel and provide 135mm OLD (dropout) spacing with a 7-speed freewheel and 15mm disc-offset.
When using an 8, 9, or 10-speed freewheel, this will increase the OLD by about 3.5mm per speed. When we assemble the motor here, we will dish and space it correctly to fit this. To install the wider wheel, you may need to spread the dropouts of the bike open in order to fit.
If you are not using disc brakes, so don't need the 15mm disc-offset, we can reconfigure the spacing to fit 135mm in many cases.
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 Fedex Hazmat and are require a signature for delivery. You may receive your kit, battery and possibly the battery rack (if applicable), on separate days.
