How to Install an E-Bike Conversion Kit on a Standard Push Bike

Introduction

Converting a standard bicycle into an electric bike (e-bike) is a cost-effective way to enjoy the benefits of electric-assisted cycling. With an e-bike conversion kit, you can upgrade your regular bike to an e-bike without buying a new one.

This guide will walk you through the installation process, covering everything from selecting the right kit to the final setup.

What You’ll Need

Tools Required:

✔ Allen keys (hex wrenches)
✔ Spanners (wrenches)
✔ Screwdrivers
✔ Cable ties (for tidy wiring)
✔ A bike stand (optional but useful)

E-Bike Kit Components:

✔ Motorized Wheel (Front or Rear Hub Motor)
✔ Battery Pack (with mounting hardware)
✔ Controller (the brain of the system)
✔ Display & Controls (LCD/LED screen, throttle, pedal assist sensor)
✔ Brake Levers (optional) (with motor cut-off function)
✔ Wiring Harness (cables to connect everything)

Step 1: Choose the Right E-Bike Conversion Kit

Before installation, make sure you have the correct kit type for your bike:

Kit Type Description Pros Cons
Front Hub Motor Kit Replaces the front wheel with a motorized one. Easy to install, balanced weight. Less traction, not ideal for off-road.
Rear Hub Motor Kit Replaces the rear wheel with a motorized one. Better traction, more power. Harder to install, affects drivetrain.
Mid-Drive Motor Kit Mounts at the crankset (pedal area). Best efficiency & hill climbing. Expensive, complex installation.

For commuters, a rear hub motor is a solid choice. For mountain biking, a mid-drive motor provides better power distribution.

Step 2: Remove the Existing Wheel

  • If using a front hub motor kit, remove the front wheel.
  • If using a rear hub motor kit, remove the rear wheel and cassette/freewheel.
  • Deflate the tire, remove the brake caliper (if needed), and carefully take out the wheel.

👉 Pro Tip: Take a photo of your bike’s setup before removing parts to help with reassembly.

Step 3: Install the Motorized Wheel

  1. Install the new motorized wheel into the front or rear fork.
  2. Make sure the axle fits securely into the dropouts.
  3. Tighten the wheel nuts or quick-release skewer securely.
  4. If using rim brakes, check that the brake pads align with the new wheel.

🔧 Rear Hub Motor: If your conversion kit includes a new freewheel, install it now before fitting the wheel.

Step 4: Mount the Battery

  1. Attach the battery holder or mounting plate to the frame or rear rack.
  2. Secure the battery in place, ensuring easy access for removal and charging.
  3. Connect the battery power cables to the controller.

🔋 Placement Tips:

  • Down Tube Mount: Best for balance (for bottle-cage style batteries).
  • Rear Rack Mount: Suitable for step-through bikes or those with no frame space.

Step 5: Install the Controller & Wiring

  1. Secure the controller to the frame or inside a controller bag.
  2. Connect the following components:
    • Motor Cable (from the motorized wheel).
    • Battery Cable (power source).
    • Throttle & Pedal Assist Sensor (PAS).
    • Display Unit & Controls.
  3. Use cable ties to tidy up the wiring along the frame.

👉 Pro Tip: Avoid sharp bends in the wires and ensure they won’t get tangled in moving parts.

Step 6: Install the Pedal Assist Sensor (PAS)

  1. Remove the crank arm using a crank puller tool (if needed).
  2. Fit the pedal assist sensor near the bottom bracket.
  3. Align the magnet disc with the sensor.
  4. Reattach the crank arm securely.

🛠 Why It’s Important: The PAS detects when you pedal and tells the motor to assist automatically.

Step 7: Install the Display & Controls

  1. Mount the LCD/LED display onto the handlebars.
  2. Attach the throttle (if included) near the right-hand grip.
  3. Install new brake levers (if your kit includes motor cut-off brakes).
  4. Ensure all buttons and controls are within easy reach.

🔹 Check: Make sure the throttle moves freely and isn’t obstructed by brake levers.

Step 8: Test & Adjust the System

  1. Turn on the battery and power up the system.
  2. Check that the display screen turns on.
  3. Lift the wheel off the ground and test the motor response using:
    • Pedal Assist (start pedaling).
    • Throttle (if included).
  4. Ensure brakes function correctly and motor cuts off when braking.

✔ Troubleshooting Tips:

  • If the motor doesn’t start, check all connections and ensure the battery is charged.
  • If the PAS isn’t working, realign the sensor and magnet disc.
  • If error codes appear, refer to the kit manual for troubleshooting.

Step 9: Secure & Finalize Setup

  • Double-check all bolts, cables, and connections.
  • Tidy up excess wiring using cable ties.
  • Pump the tires to the correct pressure.

🚴 Take a test ride in a safe area before heading onto busy roads!

Final Thoughts

Installing an e-bike conversion kit is a great DIY project that allows you to enjoy electric cycling without buying a new bike. With proper installation and maintenance, your converted e-bike will provide years of smooth, efficient riding.
