E-STREAM 1 27.5 Diamond

On an MTB, the speed score centers on rolling efficiency when you're pedaling, especially on easier terrain. Pedal assist doesn't erase physics; tire drag and weight still influence pace, and this score reflects that. The setup that matters most here is typical trail-width tires, wheel momentum that helps it carry speed between pedal strokes, mid-size wheels that balance agility and momentum, and a more...

On steep roads, it comes in at 8.2/10. Within e-mountain bikes, it sits above average. When it gets steep, the gearing feels very easy. Your easiest gear lands around 17.3 gear inches. In its peer group, it lands around the easier ~81% for low-gear climbing. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. The motor support helps you keep rolling when the slope kicks up. You’ll be able to keep a steady spin even when it gets steep. 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.

Suspension effectiveness is 6/10. That aligns with “Confident trail control”. It’s the kind of setup that stays more composed through repeated small-to-medium hits. Hardtail layout — suspension up front for control, rigid rear for a direct response. This level helps keep traction when the surface is uneven and choppy. This level usually brings more reliable wheel tracking on rough patches and repeated hits.

Balanced fit - a neutral road posture that suits most riders. This is an estimate; exact fit varies by spacers and rider setup.

In E-bikeMountain, That is why it is in the Adjustable bucket. Fit flexibility summary: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, and Cable routing is on the simpler side, which helps adjustability. In practice, it is about how easy fit changes are with normal parts and service work.

This scores 6.3/10 for comfort, so it feels comfortable out on the road. That’s the reason it lands as Race-Stiff. The posture is neutral (posture 5/10), which keeps it balanced — not overly aggressive, not overly relaxed.

In simple terms, it comes out as ‘about right’ for the category. 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’s about 12% above the typical level for similar builds. Among comparable bikes, it sits around the middle on price (cheaper than about 48% of listings). To anchor it: price €4.304 versus an estimated €3.846 for a similar build. Bottom line: it’s a normal deal — not amazing, not terrible.

This setup is aimed at fast trail riding on less extreme terrain. It has about 120 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. Suspension type (Hardtail) fits this kind of terrain.
