This will be another live video presentation from Justin Lemire-Elmore that will focus on everything about motor efficiency and system efficiency as it applies to ebike drives. We'll first explore when you should and shouldn't care about efficiency, and then go into the nitty gritty on choosing the most efficient setups for any given scenario.
This will cover mid-drive setups, both geared and direct drive hub motor setups, and will address a number of "what if" questions. Like: Is it better to go fast on the uphill so that the motor efficiency is higher or climb more slowly so that there is less power required? What is the best gear ratio to be at in a mid-motor?
The content will be be more technical than the last two presentation and will build off the initial talk on basic motor theory, which we recommend watching as a primer (https://www.youtube.com/watch?v=c96n0Ma2rLY )
