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.

Climbing rating: 5.3/10. Within e-mountain bikes, it lands around the middle. On climbs, the lowest gear feels easy. In numbers, the low gear is roughly 20.5 gear inches. Compared with similar bikes, this low gear is easier than about ~21% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. The motor support helps you keep rolling when the slope kicks up. This kind of low gear helps you stay smooth on long or steep climbs. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

For suspension control, it lands at 6/10. Category: “Confident trail control”. It’s the kind of setup that stays more composed through repeated small-to-medium hits. Full suspension helps the bike stay calmer under braking and cornering on rough sections. This level usually brings more reliable wheel tracking on rough patches and repeated hits.

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.

Comfort comes out to 7.7/10, which usually translates to a plush ride. Within Trail, Balanced basically means 'less plush than the softest builds' even though the ride still feels plush. The posture is more upright (posture 4/10), which takes some pressure off your hands on rough sections.

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. The Full setup supports this riding style.
