Performance E-Bike Conversion Kit - Lithium - Rear Wheel - 20MPH
E-BikeKit™ Rear 500w Geared Hub Motor Conversion Kit
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.
System Specs:
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: 14.2lbs (6.44kgs)
Performance: High
Efficiency: High
Stealth Factor: High
Note: geared 500w “Performance” Motors feature an internal clutch to reduce drag, and can not read speed or mileage when not in use.
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 - the 9ah Li-Ion Shrink Wrapped battery is the lightest and smallest, at just 5.8lbs. 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.
| Model | Weight | Range | Mount Style | Cost |
| 36v 9ah Shrink Wrapped | 4.4lbs | 10-22 | Battery bag with velcro straps (included, rack not included) | Base Cost |
| 36v 10ah Aluminum | 7.7lbs | 12-26 | Rear Rack (included) | +$140 |
| 36v 20ah Shrink Wrapped | 10.6lbs | 20-44 | Battery bag with velcro straps (included, rack not included) |
+$400 |
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.
