Jena Hybrid

This road-focused speed score is primarily about smooth-surface momentum and top-end efficiency. With pedal assist, the bike's tires and overall resistance still shape how fast it feels, and this score follows that idea. The setup that matters most here is a heavier build, a mass profile that isn't optimized for punchy acceleration, wider mixed-surface tires that add some drag, and a solid drivetrain that...

Uphill performance score: 4.6/10. Within e-road bikes, this comes out around the middle. You may find yourself pushing a bit more on steeper grades. That lowest gear comes out around 31.8 gear inches. Compared with similar bikes, this low gear is easier than about ~15% of them. “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. Weight is around 13.0 kg, which you notice more on longer or slower climbs. Being an e-bike helps on climbs because the assist adds steady push when you need it. Expect more grinding on climbs than easy spinning. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

In gravel terms, sitting at 4.2/10 for aero, with geometry that’s fairly neutral, it’s built for everyday ease over airflow tricks so it’ll feel calm and steady rather than ‘free speed’ fast. The short version is: it’s more about stability and everyday comfort than cutting through the wind. The fit looks fairly neutral, so aerodynamics depends more on the overall design and components than on an extreme position. That tyre width leans toward grip and stability first, with a small aero penalty at speed. Different brands share different amounts of detail, so this uses the most consistent cues that are available. In real riding, it usually feels steady and comfortable, with less advantage on open flats or into a headwind.

Comfort fit - a relaxed road posture that stays friendly on longer rides. It feels this way because there's about 55 mm of drop to the bars (moderate), with roughly 558 mm of forward stretch to the bar (long). Expect a lean angle around 31 degrees. Gravel setups typically avoid an extreme tuck for stability. Front-end spacers are estimated around 19 mm.

Here is the simple reasoning behind the fit flexibility rating: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, and A more service-friendly routing setup makes changes easier. Net result: Adjustable.

This scores 5.9/10 for comfort, so it feels moderately comfortable out on the road. That’s why it’s labeled Balanced. It’s running about 40 mm tires on 700c wheels, and extra tire volume helps mute vibration and small bumps on rough lanes and gravel patches. The posture is neutral (posture 5/10, torso ~31°), which keeps things neutral and easy to live with.

This setup is built for mixed rides where gravel is a normal part of the route. Tires around 40 mm are well suited for gravel roads and unpaved connectors. Overall, the setup matches this surface range well.
