San Bernardino County is the largest county in the contiguous United States, and for electric dirt bike riders, that size translates directly into riding opportunity. The county stretches from the suburban Inland Empire to the full depth of the Mojave Desert, with the San Bernardino Mountains rising to over 11,000 feet in between. Every major terrain type available in California, from high-elevation forest single-track to open desert to technical rocky canyons, exists somewhere in San Bernardino County.
This guide is for riders who want to understand what the county offers, what you need legally, and where to find the terrain that matches your skill level.
Legal Requirements in San Bernardino County
San Bernardino County follows California's statewide OHV framework. Electric dirt bikes like the Altis Omega, Sigma, and Delta are classified as off-highway vehicles, not bicycles, and require Green Sticker OHV registration from the California DMV. The sticker must be displayed on the bike and renewed annually.
Helmets are required for all riders in designated OHV areas. BLM rangers at El Mirage, Johnson Valley, and Stoddard Valley enforce this actively. San Bernardino County's OHV areas also enforce sound limits, typically 96 decibels for off-road bikes at most managed areas. This is where electric bikes have a genuine practical advantage: they are effectively silent compared to gas bikes, which removes an entire category of enforcement risk and is often welcomed by other park users and nearby residents.
Minors riding ATVs must follow specific state rules: under 14 requires adult supervision, and riders aged 14 to 17 need to have completed an ATV safety certification. For two-wheeled bikes, the rules are somewhat less prescriptive, but adult supervision for younger riders is always the right call at any OHV area.
No driver's license is required for off-road operation. Liability insurance is not legally required but is worth having given the remote nature of many San Bernardino County riding areas and the risk profile of desert and mountain terrain.
Where to Ride in San Bernardino County
Baldy Mesa OHV Area (Phelan)
Baldy Mesa sits in the high desert foothills north of the Cajon Pass, accessed from the Baldy Mesa Staging Area off Highway 138 near Phelan. Elevation is around 3,500 to 4,000 feet, which gives it cooler temperatures than lower desert areas and a pleasant riding environment for most of the year.
The trails here are mostly flat to gently rolling, with wide dirt roads and some single-track that loops through high desert scrub. Forest Road 3N21 from the staging area is explicitly designated for green-sticker OHVs and is one of the most beginner-friendly legal riding surfaces in the region. Ridge-top sections offer views of the San Gabriel Mountains to the south.
The staging area has a large dirt parking lot with vault toilets, picnic tables, and information boards. It is free to access (Adventure Pass may be required for some lots, check signage). The area is almost never crowded on weekdays, making it an ideal training ground for new riders who want real terrain without heavy traffic from other vehicles.
Pinnacles OHV Area (Lake Arrowhead)
The Pinnacles OHV system in the San Bernardino National Forest above Lake Arrowhead is a comprehensive trail network with routes specifically designed and labeled for each skill level. The staging area is off Highway 173 north of Arrowhead at roughly 5,500 feet elevation, which means cooler air than lowland areas even in summer.
The designated Beginner Loop (Forest Trail 3W09) is a flat, meandering route through pines and manzanita that is genuinely ideal for first-time riders. Soft loam and decomposed granite surface gives good traction. There are no large rocks or drop-offs, just gentle turns and mild elevation changes for building basic bike control.
Intermediate riders have several options: Devil's Hole Trail (2W01) descends to Deep Creek with rocky steps and a stream crossing, White Mountain Trail (3W33) climbs over sandstone outcrops, and Willow Creek Trail offers forest single-track with moderate challenges. Advanced riders access Redonda Ridge Trail (1W17), which connects Pinnacles toward Big Bear over roughly 12 miles of narrow, technical single-track with steep drop-offs, rock gardens, and tight switchbacks. This trail is one of the most challenging legal single-tracks in Southern California.
Adventure Pass required for parking. Green Sticker bikes allowed year-round. Best conditions are late spring through early fall. Snow closes upper trails in winter.
El Mirage Dry Lake OHV Area (Adelanto)
El Mirage Dry Lake is a BLM-managed area in the high desert between Victorville and Palmdale. The lakebed itself is a vast flat expanse of hard-packed dry clay that provides an extraordinary open-riding experience with no obstacles and excellent traction when dry. Electric bikes on El Mirage's lakebed are an unusual experience: total silence across a completely flat horizon, with the distant mountains as a backdrop. It is one of the most open and disorienting riding environments available anywhere near LA.
The surrounding desert terrain has sandy washes, rocky outcrops, and rolling hills. The lakebed suits beginners and anyone wanting to ride at speed in a low-risk environment. The surrounding hills and washes suit intermediate riders. The far edges of the management area have more technical sections for experienced riders.
A day-use permit is required (cooperative with LA County). Seasonal closures sometimes apply when the lakebed is wet after winter storms, as the clay surface becomes extremely muddy and riding is prohibited to protect the surface. Check BLM notices before going.
Johnson Valley OHV (San Bernardino Side)
Johnson Valley straddles the Riverside and San Bernardino county border. The San Bernardino portion includes access from Highway 247 and the communities of Johnson Valley and Lucerne Valley. The terrain here is open Mojave desert with technical rocky sections in the eastern canyons.
The rock crawling sections near Cougar Buttes on the northwest edge are particularly well-regarded among technical riders. These are natural rock formations with steep approach angles, large boulder obstacles, and narrow lines that require precise throttle control and balance. An electric motor's instant low-end torque is a genuine advantage in these environments, providing consistent power output without the need to feather a clutch on a slippery rock face.
Stoddard Valley OHV (Victorville/Barstow)
Stoddard Valley is a large open BLM riding area between Victorville and Barstow that sees moderate use except during organized race events. The day-to-day terrain includes hardpack desert, sandy washes, and rocky hill sections. The eastern portion of the area, deeper into Stoddard Mountain, has boulder canyons and natural technical sections known primarily to local expert riders.
These canyon sections are not marked on any map. They are the kind of terrain you discover by exploring from the main staging area toward the mountain edges. Natural ledges, dry waterfall drops of four feet or more, and sequences of large boulders create a natural trials course that rewards technical skill and patience.
Practical Considerations for San Bernardino County
Remote riding in San Bernardino County's desert areas means cell service is often unavailable. Download offline maps using an app like Gaia GPS or CalTopo before departing. Tell someone where you are going and when you expect to return. A tire repair kit is worth carrying in the desert, as cactus spines and sharp rocks create flats that can leave you stranded far from the trailhead.
The county's mountain areas can experience afternoon thunderstorms in summer and rapid temperature drops. Dress in layers and be aware of lightning risk at exposed elevation.
The Right Bike for San Bernardino County
The range and variety of terrain in San Bernardino County means that the right bike depends entirely on where you plan to ride. For Baldy Mesa and Pinnacles beginner loops, the Altis Delta is the appropriate starting point. For the Pinnacles intermediate network or Stoddard Valley's main trails, the Altis Sigma is well-matched. For Redonda Ridge, the technical Johnson Valley canyons, or full-day desert exploration, the Altis Omega's 75-mile range and 74-horsepower output make it the appropriate tool.
