Transform your standard bicycle into a high-performance electric commuter or trail cruiser with the 36V / 48V 500W Electric Bike Conversion Kit. Featuring a high-torque brushless geared hub motor pre-laced into a durable double-wall aluminum rim, an intelligent 26A motor controller, and optional multi-function LCD displays, this all-in-one conversion system delivers dependable hill-climbing power, smooth pedal assistance, and speeds up to 32 km/h (20 mph).
Why Choose This 500W E-Bike Conversion Kit?
-
High-Torque Geared Hub Motor: Delivers 60–63 N·m of torque and 265–325 RPM for effortless starts, steep hill climbs, and efficient energy consumption.
-
Front or Rear Wheel Installation: Choose front hub (100mm dropout) for quick, tool-friendly installation or rear hub (135–142mm dropout) for enhanced traction and handling.
-
Universal Wheel Size Compatibility: Available in 20'', 24'', 26'', 27.5'', 28'', 29'', and 700C rims to fit mountain bikes, hybrid commuters, city cruisers, and road bikes.
-
Advanced 26A 9-MOSFET Controller: Intelligent dual-voltage (36V/48V compatible) controller with smooth current management, thermal protection, and instant throttle/PAS response.
-
Full Riding Control: Includes sensitive thumb throttle, 12-magnet pedal assist (PAS) sensor, and safety cut-off brake levers/sensors that disengage motor power immediately when braking.
Intelligent 26A Controller & Custom Display Options
The included 26A brushless motor controller features 9 high-efficiency MOSFETs with a maximum current rating of 26±1A, ensuring cool, reliable operation during continuous climbs and heavy acceleration. Customize your handlebar cockpit with your choice of intelligent LCD displays (EN06, S866, S900, GD02, S869, S966) to monitor real-time speed, battery voltage, mileage, pedal assist levels (1–5), and system diagnostics.

Frequently Asked Questions
How do I know if this conversion kit fits my bicycle?
Check two key measurements: your wheel diameter and your fork dropout width. For front-wheel kits, your front fork dropout width should be 100mm. For rear-wheel kits, your rear dropout width should be between 135mm and 142mm. Ensure your tire diameter matches the selected wheel size (20'', 24'', 26'', 27.5'', 28'', 29'', or 700C).
Should I choose a front or rear hub motor?
Front hub motors are the easiest and fastest to install because they don't require removing or adjusting your rear cassette, derailleur, or chain. Rear hub motors provide superior rear-wheel traction, better handling on steep inclines and loose gravel, and support standard multi-speed freewheels.
What battery is recommended for this 500W kit?
You can use any 36V or 48V lithium-ion e-bike battery rated for at least 26A continuous discharge current. A 36V 13Ah–17.5Ah or 48V 13Ah–20Ah battery is recommended for typical ranges of 40–80 km (25–50 miles) depending on assist level and terrain.
Are disc brakes and rim brakes supported?
Yes. The hub motor features standard 6-bolt disc brake mounting holes (44mm BCD), and the aluminum rim CNC braking surface supports conventional V-brakes and caliper rim brakes.
Does E Smart Way provide warranty and free shipping?
Yes, all conversion kits from E Smart Way come with dedicated customer support, warranty coverage, and storewide free shipping.
