1. The Technology Behind Electric Motorcycles
Kick Gas
The Technology Behind Electric Motorcycles
-Discussing some background on EVs, particularly motorcycles, what is out there now and what the cutting edge is.
-Talk about the environmental impacts, but not a ton of time on this because I'm guessing you've talked about this already (and there's not a ton of time).
-What are the main challenges, and discuss the different types of batteries and motors, the pros and cons of each.
-And finally really drive home that innovation is needed (especially since most electric motorcycles are basically using repurposed fork lift or golf cart motors right now...)
Then open up to questions and discussion. Maybe take 45 min for >>> this, then head outside to see my bike.
