Integrated Power Unit
For the ROTWILD Aggressive Series a battery with 375 Wh was newly developed, which weighs only 1.9 kg. Outside it consists of a compact and handmade carbon case. Inside 20 modern cells of the cell type 21700 with 5000 mAh are used.
In order to meet the requirements of the high mountains, the new IPU750 uses the highest performance cell technology of the type 21700. The new battery cells offer over 60 percent more capacity than the 18650 cells currently widely used in e-bike batteries.
The new, ultra-compact Shimano drive weighs less than 2,500g, convinces with 85Nm, 50% less pedaling resistance, 20% higher motor efficiency with reduced noise level (cf. STEPS E8000) as well as seamless fade-out/fade-in at the support limit.

The drive offers a maximum power of 90 Nm over a wider cadence range and improved response in technical terrain. The Flex Power Mode provides dynamic support, the "Cadence Power Control" provides up to 30% more power at high cadences, the "Progressive Pedal Response" offers an even faster and more sensitive response.
