I think I remember empulsebuyer’s old site, and this is much better. Also, he has added some “apps”. Basically they are calculators to help you figure out how many PV (photovoltaic) panels you need to buy to offset the electric usage of your EV (he has a lot of models to choose from), and help you see how long until your EV is or isn’t saving you money compared to a gas powered bike. Again, he has many models to chose from. It is a fun it to play on.
