Topstone Neo Carbon 2

This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. On an e-bike, the motor helps, but the bike's rolling setup still matters - this rating captures that side of speed.

If your rides include hills, it rates 3.9/10 for climbing. Within e-road bikes, it sits below average. The easiest gear leans spin-friendly when it tilts up. The easiest gear works out to about 25.4 gear inches. On the ‘easier low gear’ scale, it sits around ~71% versus similar bikes. “Gear inches” sounds nerdy, but it’s just a quick way to describe how easy your lowest gear is to turn uphill. Lower usually means easier. Being an e-bike helps on climbs because the assist adds steady push when you need it. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. 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.

On the gravel side of things, coming in at 4.5/10 on aero, it’s aero-aware without going extreme so you get some benefit when the wind matters. Put simply, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Different categories trade aerodynamics against comfort and stability—gravel is part of that story. Tyres around 37mm are a practical middle ground, with a small aero trade-off compared with narrower race tyres. It’s a middle-ground feel: not the fastest possible in the wind, but not holding you back either.

Comfort fit - comfort-leaning without feeling sluggish. Gravel geometry often balances comfort and control over rough surfaces. Mostly geometry-based, with a small category-based estimate.

What affects adjustability on this bike: Standard cockpit parts make it simpler to fine-tune your position over time, Routing is relatively straightforward, which helps when you change cockpit parts. Another point: A dropper makes it easier to shift between climbing and descending positions. Net result: Adjustable.

Comfort comes out to 5.4/10, which usually translates to a fairly neutral ride. That’s why it’s labeled Balanced. It’s running about 37 mm tires on 700c wheels, and wider tires let you drop pressure a touch, which smooths out rough pavement on rough lanes and gravel patches. The posture is neutral (posture 5/10), which balances comfort and responsiveness pretty well.

The price feels a touch strong for the parts listed. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the spec estimate, it’s about 20% above the typical level for similar builds. Compared with similar bikes, it trends a little expensive (cheaper than about 37% of listings). To anchor it: price €7.250 versus an estimated €6.050 for a similar build. Put simply: it’s a bit pricey for what you get.

This setup works well when your ride switches between tarmac and easy unpaved sections. Tires around 37 mm are a good middle ground for varied surfaces. Even though it’s tagged Gravel, the spec pushes it toward All Road.
