Example of e-bike kit installation

So you have decided to build your e-bike using electrification kit. And you would like to do it by yourself. In this blog post, we will try to give you a general understanding of how this process looks like. Here we will cover what instruments you might need and what actions you will need to undertake. In other words, this guide is a simplified instruction manual that will answer your question: Will I manage on my own or should I buy installation service as well?

So, you have received your e-bike kit. What is inside?

The content of City+ kit

City+ kit

  • Motor
  • Plug-in cable
  • Brakes
  • Thumb or twist throttle
  • Cruise control button
  • Pedelec sensor
  • Torque arm
  • Battery suitable for your bike: frame or rack

Extras for City+ kit:

  • LCD
  • Programming cable

Required tools

Remember, you may also need other tools depending on your specific bike and components. For example, some bicycles don’t have frame mounts for the battery, hence you will need to drill them by yourself.

  • Zip ties
  • Allen Wrench
  • Adjustable wrench
  • Phillip screwdriver
  • Gear removing tool (in case you install rear motor)
  • Sprocket Remover (in case you install rear engine)
  • Crank Puller (if you want to install pedelec sensor)
  • Soldering iron kit (you may need it to shorten cables to perform appropriate cable management)

So, you now have your e-bike kit and prepared all tools. You are ready to start assembling.

Installation process

Firstly, you need to prepare electric motor wheel:

  1. Remove the original front/rear bicycle wheel
  2. Remove original freewheel and disc brake (optional)
  3. Mount freewheel on the motor (optional)
  4. Mount disk brake (optional)
  5. Mount inner tube and tire

Then install the hub motor on the front/rear fork. Make sure the engine is fully sitting on dropouts. We recommend using torque arms to strengthen bicycle dropouts. Make sure you mount the torque arm as vertical as possible.

Secondly, place the battery. If you have a rack battery, simply replace your original rack. In the case of frame type, attach the mounting plate to the frame of the bicycle. Now you can place the battery pack into a rack or mounting plate.

Thirdly, install handlebar accessories: brakes, throttle (optional), cruise control (optional), LCD (optional). Brakes turn off the engine when you brake. Hence you will need to replace your original brake levers with the ones that come with the e-bike kit. But if you want to keep your original ones (especially if you have hydraulic brakes), you can purchase separately special braking sensors.

In case you want to use your e-bike as pedelec, you will need to install pedelec sensor. To do so, you need to remove the left pedal crank arm and install all components. Then mount back the pedal crank arm.

Now, everything is installed, and it’s time to connect wires. Use wiring diagram for proper connection. Use zip ties to fix cables in the right place. You can also shorten cables where needed to have a neat look of your e-bike.
