What I found interesting and curious is the departure from the small chain ring in the new design. I have always assumed the efficiency and reliability that the Bosch system is known for was gained from the ability of allowing the motor to spin faster as most electric motors perform better at higher RPM. Another question to ponder is now that the new design has gone with the bigger chain ring and has achieved a quieter drive does that suggest they are also using a belt in the motor similar to the Brose systemWould have preferred a way bigger battery. 500Wh is simply too small for my needs. I'll probably go for the dual battery setup if I switch to Bosch.

@Ravi, I only stated the Bosch system was efficient....not the most efficient.You're mistaken!
The motor still runs at high rpm but the gearing is different.
And if you thought Bosch was the most efficient, then you certainly need to put more saddle time on the other systems![]()
I've thought about this since I read the same notice about the R&M Charger being delayed for US release. I think Bosch is playing the long game here, knowing that our market is in its infancy relative to Europe. They may not want to risk the brand by releasing cutting edge products first in America. They are well established in Europe, so a product that may be less durable (take Nyon, for example) might be acceptable there, since the repair/replace network is ubiquitous. From what I understand, Bosch has contracted with Magura to act as a warranty representative here in the States; their contract may impose some limitations on the allowed product range.Anybody in the industry heard anything about Bosch's plans for bringing the PowerTube batteries to the US market? Manufacturers are starting to announce their 2018 lineups with October/November releases for PowerTube models. Bosch's US ebike (Link Removed - No Longer Exists) makes no mention of the new batteries (or new Active Line motor) while their international (Link Removed - No Longer Exists) does. I wonder if this is going to be like the Nyon. I've been wanting to upgrade from my 2015 Specialized Turbo X to a mid-drive. In my testing, I prefer the Bosch motors to the others, but aesthetically I want an integrated battery. I got very excited when I first saw this thread, but once I saw Riese and Muller's new Chargers and Superchargers weren't going to be available in the US, I had a feeling it was because of a lack of Bosch support.
