RFN SX-E15 74v Electric Dirt Bike
The ultimate dirt bike for Utah riding from trail to track. If you ride in Utah, this bike just makes sense. The ultimate super mini or wife/daughter bike. Completely customizable from the cockpit to make it feel like a full race bike or just like a little 125cc 4-stroke.
Unlike the other E-motos on the market that are nothing more than a mountain bike with a motor and battery strapped onto it, this bike is a true dirt bike. Moto brakes, stock Kenda tires, fully adjustable suspension.
The RFN SX-E15 Plus is hands-down the most controllable electric dirt bike I’ve ridden in tight single track and hard enduro. It has 5 power modes (we teach our daughters to ride on this then use it as our trailer bike). The power delivery is smooth and predictable, so you can creep through technical rock gardens, ledges, and switchbacks without fighting the bike or worrying about stalling.
When you open it up, it absolutely rips. It has a top speed of 62 mph. 15 Kilowatts of power at the tire (other brands measure directly from the motor) making this the most powerful bike in it’s price class. Plenty for motocross tracks and fast desert sections, and the power feels strong but never overwhelming.
Range is a huge win too. You can get hours of trail riding (up to 50 miles) or solid moto sessions, and if you want more—the battery swaps in about 90 seconds. Pop a fresh pack in and you’re right back on the bike.
No clutch, no stalling, instant torque, and incredibly quiet—perfect for trails, canyons, practice tracks, and anywhere you want to ride without drawing attention.
If you want one bike that truly does everything—single track, hard enduro, and motocross—the SX-E15 Plus is hard to beat.
