NYTRO E5 GRAVEL – SRAM RIVAL AXS

On asphalt, it's mainly a question of resistance and efficiency, and that's what the score summarizes. Relative to performance-oriented builds, this build is shaped by wider mixed-surface tires that add some drag and a more budget-friendly drivetrain that focuses on value. Put simply, it prioritizes confidence and everyday riding over outright pace.

If your rides include hills, it rates 4.4/10 for climbing. Within e-road bikes, it lands around the middle. The low gear should feel friendly on most hills. Your easiest gear lands around 23.8 gear inches. On the ‘easier low gear’ scale, it sits around ~79% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. E-assist can take the sting out of steep ramps, especially at lower speeds. It won’t be the absolute best climber, but it won’t hold you back on most climbs either. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

On the gravel side of things, aero-wise, at 4.8/10, with more integrated details, it keeps decent wind efficiency without becoming a specialist so it won’t hold you back on normal fast riding. 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 40mm are clearly aimed at comfort and control, and that usually adds some drag in the wind. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. Specs can vary by market and model year, so the summary follows the strongest published signals. That typically means solid everyday speed without forcing an aggressive position or race-only parts.

Balanced fit - a neutral road posture that suits most riders. You get this posture because handlebar height is roughly 84 mm lower than the saddle (large drop), and how far you'll be stretched forward is about 552 mm (long). Expect a lean angle around 36 degrees.

Here is the simple reasoning behind the fit flexibility rating: A modular front-end gives more freedom to change stem length or bar width. At the same time, Less routing complexity makes swaps and adjustments more practical. Net result: Adjustable.

This scores 6.0/10 for comfort, so it feels balanced out on the road. That’s the reason it lands as Balanced. It’s running about 40 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, torso ~36°), which balances comfort and responsiveness pretty well.

This bike is comfortable on gravel roads and unpaved back roads, and it still rides well on tarmac. The tire size is around 40 mm, which gives grip and control on loose gravel. Overall, the setup matches this surface range well.
