RIDON FS 504

On an MTB, the speed score centers on rolling efficiency when you're pedaling, especially on easier terrain. Compared with bikes built for pure pace, this build is shaped by relatively narrow MTB tires that roll quickly, wheel momentum that helps it carry speed between pedal strokes, and a more budget-friendly drivetrain that focuses on value.

Overall on climbs: 5.3/10. Within e-mountain bikes, it sits around the middle. It has an easy low gear for steady climbing. In numbers, the low gear is roughly 20.5 gear inches. In its peer group, it lands around the easier ~21% 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. E-assist can take the sting out of steep ramps, especially at lower speeds. You’ll be able to keep a steady spin even when it gets steep. 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.

Suspension handling is rated 6/10. It matches “Confident trail control”. It’s the kind of setup that stays more composed through repeated small-to-medium hits. With suspension in the front and rear, the bike can stay more settled through repeated bumps. Expect steadier tracking on rougher sections without feeling like a long-travel downhill setup.

Comfort fit - comfort-leaning without feeling sluggish. That's driven by the cockpit sits 12 mm below the saddle (a very small drop), and the cockpit stretches you forward by ~576 mm (long). Estimated lean is about 23 degrees.

In E-bikeMountain / Trail, Overall, it falls into Adjustable. Why this fit flexibility rating: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, The front-end is easier to work on, supporting fit tweaks over time. Also, Seatpost info looks fairly neutral, so most fit change comes from cockpit choices.

Ride comfort is 7.7/10 — on a real ride it feels very smooth. Within Trail, Balanced basically means 'less plush than the softest builds' even though the ride still feels very smooth. The posture is more upright (posture 4/10), which keeps things more relaxed, especially on long rides.

This setup suits typical singletrack and varied natural terrain. It has about 130 mm of suspension travel (how much it absorbs bumps), which works well for everyday trails. Overall, the setup matches this surface range well.
