Electric Carbon Road Bike E-EDR CF Mahle X20 Shimano 105 Di2

When the riding is smooth, speed comes down to resistance and weight, and that's what this rating emphasizes. In real riding, it lands in the middle: capable pace, but not optimized for outright speed. The biggest contributors are a heavier build, an aero-leaning setup that reduces drag at higher speeds, all-round road tires that balance speed and comfort, and a basic drivetrain spec that prioritizes practicality...

On steep roads, it comes in at 5.3/10. Within e-road bikes, it sits around the middle. It has a middle-of-the-road low gear for climbing. In numbers, the low gear is roughly 27.0 gear inches. Compared with similar bikes, this low gear is easier than about ~54% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. With about 12.0 kg to haul uphill, pacing matters more on longer grades. The motor support helps you keep rolling when the slope kicks up. Good for keeping cadence steady on climbs without overcooking it. Real-world feel depends on setup and size, and some details aren’t always listed, so this is best seen as a well-informed estimate.

In general road terms, scoring 5.9/10 on aero, it’s an all-round aero level so it feels ‘quick enough’ without being a pure aero build. In everyday language, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. The general road category also hints at the intent behind the design. That tyre width is common on performance road builds and tends to suit aero goals. A tidier cockpit and cable routing can help a little once you’re riding quickly. Not every brand publishes the same detail, so this leans on the clearest available specs. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Balanced fit - a middle ground between comfort and speed. This is an estimate; exact fit varies by spacers and rider setup.

This bike's adjustability comes down to cockpit, routing, and seat setup: This front-end is not locked into a one-piece system, which helps adjustability. At the same time, Internal cable routing can slow down fit-related part changes. Net result: Moderately Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Comfort comes out to 5.3/10, which usually translates to a fairly neutral ride. That’s the reason it lands as Balanced. It’s running about 37 mm tires on 700c wheels, and extra tire volume helps mute vibration and small bumps on chipseal and broken pavement. The posture is neutral (posture 6/10), which balances comfort and responsiveness pretty well.

This looks like a great buy for the spec on paper. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the spec estimate, it comes in about 15% under the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 64% of listings). To anchor it: price €4.743 versus an estimated €5.567 for a similar build. Not every spec detail is consistently published, so think of this as a strong hint rather than the last word. Overall, it looks like a great-value pick in its category.

This bike is built for longer mixed-terrain days and rougher unpaved riding. The tire size is around 50 mm, which supports comfort and control on rougher ground. It’s listed as General Road, but the setup aligns better with Adventure.
