E-BikeKit™ Rear 500w Geared Hub Motor Conversion Kit
with 36 Volt 9 Amp Hour (AH) Lead-Acid Battery Pack and 2 Amp 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 economical electric bike conversion kit system is for riders on a budget that want the power and efficiency of the 500w Geared hub motor combined with the affordability of a sealed lead-acid (SLA) battery.

Sealed Lead-Acid (often referred to as “SLA”) batteries provide a reliable battery option at a low price point. SLA battery packs are the most affordable option but they are also the heaviest option. Lead-Acid batteries have a much lower weight to power ratio than lithium-based batteries and far less the number of charge cycles (how many times a rechargeable battery can be charged from 0-100%). The performance of lead-acid is low; as the pack is spent, the performance is lessened. The lead-acid battery costs less initially, but over time, the “cost-per-cycle” is almost double the cost of li-ion. SLA packs should be charged immediately after each use.
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).
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.
