9. Team Breakdown

10. Background Hub Motor Mid Drive Easier to retrofit a non-ebike
Trek eBike
Easier to retrofit a non-ebike
Not-ideal wheel weight distribution
Direct drive
Less chair wear
More torque
Better weight distribution
Can take advantage of the gear train
More easily integrated with pedal force feedback

11. Background World wide e-bike demand is increasing
eBikes are a clean and efficient alternative mode of transportation.
