    I love the idea of e-bikes, but I’m so sick of getting excited… then seeing the price. I guess if nothing else it’s emboldening me to build my own, without any government restrictions.

    Lol on my price estimates, I didn’t realize it was a 650wh battery, I guess a good general rule is about $1 per watt hour on lithium ion/polymer. Realistically they’re probably still making $1000 profit in each bike.

    Batteries are changing quickly right now, I think lithium ion/18650 is outdated at this point. Costco has some lithium iron phosphate 1300wh for $650 each basically a car battery that weighs 20 pounds instead of 50 pounds, and can be charge cycled 3500 times at full depth discharge.

    I just found two free bmx bikes last month, maybe this could be a fun winter project.

      I have the ion battery my bike came with and 2 LiFePo4 batteries ( 20ah @17lbs & 35ah @27lbs ).

      I think for the average person if you have a bike the a lot is a GREAT way to go.

      Oh, and the new sodium batteries are now on Alibaba insanely cheap - so your point about battery tech is solid.
