I heard this comes out in October. 2,100 dollars to let you use the same battery you already bought with the bike. Is it just me or does that sound high for allowing you to use the full battery on a bike you already bought because they held back the performance of the battery? You would think they would want to give people more range to help accelerate the product purchases by word of mouth. I could see 300 for this upgrade, 2,100 to use what should have been installed from the factory just seems high.
