It is always a fight to make electric bikes feel natural when riding. Its even harder to do so when you’re trying to keep the system as lightweight as possible. But MAHLE really focused on improving ride feel, and they seemed to have pulled it off here. No, I haven't connected any range extender nor delimiter, the battery was faulty from factory (the most likely).

MAHLE intends for the X20 electric drive system to be used in lightweight, high-performance gravel, road, and cross-country bikes. All of these bikes are designed not for range or power, but to be fun to ride, and a pleasant way to get around. Bikes with the MAHLE X20 drive system include the BMC Roadmachine AMP TWO, Orbea Gain, and SCOTT Addict eRIDE. Currently, BMC offers the Roadmachine AMP ONE with a MAHLE X20 drive system. It features a 350 Wh battery with the option for a range extender. SHOP BMC ROADMACHINE AMPSo if there is anything going on in parallel, then I think there must be electronics managing this. Both batteries connecting to separate parts in the electronics and the electronics managing the current flow from both batteries to the motor. The previous iWoc ONE controller was often hard to understand, with LED colors indicating a combination of battery life, connectivity, light options, and assist levels. While the LED colors still require some homework to understand their meaning (which we’ll get into), the big difference is the LED bar that shows battery life. Is there more of a white light showing? Then there’s more battery. And if your battery is low, then the light bar will be dim.

SCOTT says the new Addict eRIDE is a version of the Addict RC road bike, just electrified. We’d call it closer to the standard Addict, but that’s no bad thing. Geometry is decidedly endurance oriented, with an aim for a more comfortable rather than more aggressive rider position. The wheelbase is slightly longer in an effort to improve high-speed stability. But the classic tech is there: fully-integrated cable routing, a D-shape seatpost, and aero tube shaping.

This latest MAHLE Smartbike system is lighter, smarter, and overall a much more user-friendly experience. The wildest part of it all? The system weighs in at just 7 pounds (3.2 kg), and that’s including the 250 W battery option in the downtube. The X35 Range Extender is compatible with Gain F, Gain M and Gain D models from 2018 and Gain and Vibe and Optima models from 2021. The X35 Range Extender is not compatible with the eMX24 model. Charging while riding: When the consumption of the motor will be lower than 2A (downhill, no assistance or over 25km/h, all the energy doesn’t consumed by the motor will charge the main battery (by this way we compensate the extra consumption during uphill) When attached to Gain, the Range Extender supplements the bike's main internal battery, which has a current capacity of 248W / h, and adds an additional 208W / h. This brings the total battery capacity to 450W / h, giving a 70% boost to the internal battery's charge.
