Here is an overview of my completed electric bike.
QS205V3 3.5T motor laced into a 17″ Moped rim.
20S 2P of the HobbyKing Graphene Professional Lithium Polymer 10AH batteries
Mobipus 72200 FOC controller
Self made Arduino / Neopixel brake lights and turn signals
Rockshox Boxxer World Cup front fork, DNM rear shock.
It’s current top speed has been GPS measured at 62MPH and I don’t have any field weakening enabled, so I could go faster, I just don’t have any desire to.
When the weather is nice, this is how I commute to work.
