About this trail
In Sierra National Forest, California, Ridge (USFS trail 21E254) covers 0.7 mi of National Forest System trail. This profile summarizes what the official US Forest Service trail record says about riding it: how long the trail is, what it's built on, how steep the route grades out, and which forms of bike use the agency has designated. The tread is mapped as native material. Based on slope, this is a Intermediate trail (grade band 8-10%); that reflects moderate gradient and is not the same as a technical MTB difficulty rating. For traditional mountain bikes, use is restricted according to USFS data. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated (January, Mar–Dec) — Class 1 being pedal-assist only, Classes 2 and 3 adding a throttle and higher assisted speed. The route is mapped as USFS Trail Class 2 on the agency's 1-to-5 development scale, where 1 is the most primitive, minimally maintained tread and 5 is the most developed. Treat this as a planning reference rather than a live conditions report, and verify any time-sensitive closure or order with the ranger district that manages Sierra National Forest.

How we read this data
Grade-based difficulty above is the USFS grade (route steepness), not a technical mountain-bike rating — a gentle-grade trail can still be rocky or technical, and vice versa. Bike and e-bike status come verbatim from the USFS managed-use fields for this trail; we never infer access we can't cite. See our methodology for how the dataset is built and what each field means.
