MAHLE’s thinking is that a lower peak torque is necessary here, as these bikes often will have lower grip from narrower, road-oriented tires. The lower max assist also should be smoother, without the jerky feel of the most powerful systems. In this writeup - and video review - we’ll give an overview of the features, how it's changed over the MAHLE X35, and whether the changes amount to a better electric bike. The Range Extender and main battery can be charged at the same time by connecting the Range Extender to the main battery and the charger to the Range Extender. No, I haven't connected any range extender nor delimiter, the battery was faulty from factory (the most likely). THe X35 Range Extender gives you another 208Wh (70%) offering nearly 2 hours of additional boost at maximum power assist — something unheard of in the industry.

SCOTT currently offers the MAHLE X20 system in five models in the Addict eRIDE lineup. Four are standard Addict eRIDE bikes and one is the Contessa Addict eRIDE 15. All feature the smaller (and lighter) 250 Wh battery, though a range extender is bundled with the Addict eRIDE Ultimate. So 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. Put a BMC Roadmachine AMP next to a standard Roadmachine, and you’d be hard-pressed to tell the difference between the two bikes. Really, the downtube is slightly larger than the standard Roadmachine, and the rear end is slightly different. But what the Roadmachine AMP offers is a SRAM Rival eTap AXS drivetrain, a lightweight carbon frame, and the exact same geometry as the standard road bike. If they just brutally put both batteries in parallel each time you connect the range extender without specific electronics managing anything, then I fear for the life span of the internal battery (and that of the range extender at the same time). When attached to Gain, the external device charges the bike's main internal battery, which hascurrent capacity of 248W / h, and adds an additional 208W / h to the Ebikemotion X35 systems. This brings the total battery capacity to 450W / h, giving a 70% boost to the internal battery's charge.

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. The charger is compatible with Gain F, Gain M and Gain D models from 2018. The external charger is not compatible with the eMX24 model. 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. That sounds like a pretty awful setup, I presume if you were actually pushing the main hard with usage the range extender charging rate wouldn't be able to keep up? In the case of this range extender this will never be the case. One of the batteries (internal or range extender) will be more charged than the other, it will be older or newer and not at all of the exactly the same type.

Price Matches may only be honored on identical items. The product must be the same make and model (i.e., the same size, color, year, etc.). 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.The MAHLE X20 system now uses a standard 12mm thru-axle bolt to remove and install the rear wheel, the same as any normal disc brake bike. If you can remove a rear wheel on a normal bike, you can do it on this one. The HMI controller shows four colors to indicate the assist level. White for no assist, green for low assist, orange for medium assist, and then red for the highest, most aggressive assist. A yellow light indicates the lights are on or off. A blue light indicates a Bluetooth connection is being connected or disconnected. See a flashing orange light? That is a warning that functionality is limited; you can continue riding, though keep an eye out for what might be wrong through the MySmartBike app.
