About this trail
In Caribou-Targhee National Forest, Idaho, Tincup Driveway (Marshall Cyn) (USFS trail 5463) covers 4 mi of National Forest System trail. Everything below comes straight from the US Forest Service National Forest System Trails dataset — length, surface, slope-derived difficulty, and the specific bike and e-bike designations on record — so you can check legality before you load up. Underfoot, the trail is recorded as native material. Its grade-based difficulty is Intermediate (grade band +8-10%) — a moderate steepness profile derived from USFS slope data, not a technical mountain-bike rating. Mountain bikes are allowed, open year-round in the data. The agency lists no Class 1, 2 or 3 e-bike designation here; absent a local order to the contrary, that means e-bikes are not an allowed use on this trail. 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. Because conditions, closures, and local orders change between data refreshes, confirm the current status with the managing ranger district before you ride.
