Actually, ebikes need energy density the most. They tend to not have fast public charging. A lighter ebike has huge advantages, if only for maneuvering a couple of stairs or over a log, but also in suspension and handling + a huge difference in range/acceleration.
For an EV, you don't need "race car" performance, and heavy chemistries are ok. Bike performance just gets a huge boost from relatively minor cost to improve weight/range and performance.
EV’s already weigh more than most of their ICE equivalents. I don’t think we want even heavier chemistries in them. You could reduce the battery capacity to keep the weight down but then it’s a double hit to range.
Heck a Model S weighs more than a fair number of F150’s on the road.
Model S: 4,323-4,960 lbs
F150: 4,021-5,540 lbs
