Interesting, it seems they are buying cells from China and putting packs together with a novel way of keeping the cells cool they've come up with. I'm not sure their thermal management system is really needed for a low power ebike pack, but they seem to have come up with a neat way of fitting cylindrical cells together, all the same.
A point that does worry me though is this load of cobblers, taken straight from their ebike web page:
"Over 80% of electric bikes produced today are powered by either lead acid or nickel metal hydride batteries. While lithium-ion’s higher cost and safety concerns are the main causes of its low adoption rate, the result is significantly heavier e-bikes that have low power and a short range. Of the e-bikes using Li-ion batteries, lithium polymers are the prevalent choice. However, these chemistries sacrifice power, range, and cycle life for safety."
Either they are way, way, behind the curve when it comes to ebike power packs, or they have just done a cut'n'paste job from another site without checking if the data are up to date and correct.
Another slight worry is that they play heavily on the lithium battery safety aspect, something that we now know is already over-stated and subject to a lot of hype.
I'd be interested to see how their prices compare to someone like Ping, though. If they can make a product as reliable as his, with the same level of good customer support, for a price that's comparable, then that has to be a good thing.
