I've decided to buy a folding electric bike for a short (6-7km each way) commute (+train) in Australia. I have basically two options:
IZIP EZGO Folding Bike - Lead-acid, Australian$1,000
Sherpa MK3 Lithium, Australian$2,000
Doe anyone have experience of either of these? Is it worth paying twice as much for Lithium?
I'm also a bit worried that, like my laptop battery, the lithium will lose it's charge over time. is that a problem usually?
