Battery-Run Lights

  • Kevin McAndrew
The old lights on my bike were just plain Jane bike lights from halfords. They are liable to be easily stolen, run out of internal battery and they aren’t very bright.

VESC FOC

  • Kevin McAndrew
I wasn’t happy with the power that I was getting from the motor. Furthermore, it wasn’t as smooth as I would have liked.

FOC Motor Control

  • Kevin McAndrew
I am currently using standard Brushless DC (BLDC) control which uses a 6 step method of controlling the motor. However, there is a different method of control called Field Oriented Control (FOC) which is more efficient and gives maximum torque.

Initial Testing

  • Kevin McAndrew
I now have the battery, controller, motor, throttle and new compartment successfully installed. Initially, I performed a 5km test which contained a few hills and flat sections.

Building a new Compartment

  • Kevin McAndrew
The battery and controller need a compartment to protect them from wind and rain and to keep them secure. The old compartment had a middle section made of black PVC gutter that was heated and formed.

Building a Wheel

  • Kevin McAndrew
Since I chose to buy the hub motor by itself with no rim, spokes or tyre, I had to get these parts and build the rest of the wheel myself.

Hub Motor Shopping

  • Kevin McAndrew
The last drive train that I had consisted of a Remote Control (RC) plane Brushless DC (BLDC) motor, two pulleys and a timing belt.

Electric Bike

I have built a number of electric bikes in the past: V1: Nissan Almera windscreen wiper motor and switch V2: Hobby BLDC motor, VESC controller and soldered battery V3: Same as V2 with better motor mount and modular battery
