    New cell sizes and cell chemistries - going from 2170 to 4680 and beyond

    Ever since the Tesla battery day, the whole battery industry has been working hard to develop better cell structures and chemistries - 4680-sized are going in the new Tesla Model 3 and Cybertruck but I don't think we would see such that in the E-bike world any time soon. These cells are MASSIVE...

    Step thru looking good!

    As of now, it is programmed to be 20 mph, but if you're mainly riding off-road, we can offer something suitable for you. Regarding your question, we found that tuning a mid-drive torque sensor is far easier than tuning a hub-drive torque sensor. This is one of the reasons, many hub-drives...
