8,000W Peak Power
This is where the Ultra earns its name.
The EM-5 Ultra steps up to a 72V electric power system capable of producing up to 8,000 watts of peak power.
With 3,000W rated power and up to 203 lb-ft of maximum motor torque, the Ultra is designed to deliver the immediate acceleration and hard-hitting response riders expect from a high-performance electric dirt bike.
Power is transferred through a chain-drive system, creating a responsive and connected dirt-bike riding experience without a clutch, gears, gasoline, or traditional engine maintenance.
Twist the throttle and go.
Up to 56 MPH
The EM-5 Ultra reaches a manufacturer-rated maximum speed of 56 MPH, making it the fastest model in the EM-5 lineup.
Three selectable riding modes let you choose how much performance you want available:
Mode 1 — 30 MPH
Reduced maximum speed for getting familiar with the bike and more controlled riding.
Mode 2 — 42 MPH
A substantial increase in performance for faster trail and open-area riding.
Mode 3 — 56 MPH
Unlocks the EM-5 Ultra's maximum speed for experienced riders in appropriate off-road environments.
The Ultra also adds reverse gear, making it easier to reposition the bike or maneuver out of tight riding areas.
72V 25Ah Samsung Battery
High-performance electric bikes need serious batteries.
The EM-5 Ultra uses a 72V 25Ah Samsung battery, providing approximately 1,800Wh of nominal battery capacity.
Valtinsu rates the EM-5 Ultra for up to 75 miles of maximum range, giving riders the potential for longer dirt sessions and more time between charges.
An included 84V 5A charger provides a manufacturer-listed charging time of approximately 7–8 hours.
Actual riding range will vary based on speed, terrain, rider weight, elevation, temperature, tire pressure, riding mode, acceleration, and other riding conditions.
203 lb-ft Maximum Motor Torque
The Ultra isn't just about top speed.
Valtinsu rates the 72V drive system at up to 203 lb-ft of maximum motor torque, giving the EM-5 Ultra strong response from a stop and substantial pulling capability when the terrain gets demanding.
That additional torque is especially useful for acceleration, inclines, loose surfaces, and situations where immediate power delivery matters.
Valtinsu also rates the Ultra for climbing inclines of up to 45 degrees under specified conditions.
Reverse Gear
Sometimes one of the most useful performance features isn't about going faster.
The EM-5 Ultra adds reverse gear, helping riders maneuver the bike when turning around, repositioning in a garage or staging area, or getting out of a tight spot on private riding property.
It's a small feature that can make a big difference on a 143-pound electric dirt bike.
Dirt-Ready Suspension
The EM-5 Ultra combines high performance with suspension designed for uneven off-road terrain.
Up front, hydraulic shock absorbers provide approximately 5.9 inches of stroke, helping absorb bumps and impacts while keeping the front end controlled.
At the rear, an adjustable air suspension system with approximately 2 inches of stroke provides additional support and adjustability.
Combined with the Ultra's larger wheel configuration, the suspension helps create a more composed ride across dirt, grass, trails, and changing terrain.
17"/14" Off-Road Wheel Setup
The Ultra rolls on a 17-inch front and 14-inch rear wheel combination.
This staggered dirt-bike configuration helps the front wheel roll across uneven terrain while maintaining a compact, responsive overall platform.
With a 31.5-inch seat height, the Ultra remains considerably more approachable in size than many full-size electric motos while delivering serious performance.
VA LCD Display
A VA LCD display provides clear access to important riding information from the handlebars.
The EM-5 Ultra also includes a square headlight and horn, adding useful functionality to the off-road platform.
IPX6 Protection
The EM-5 Ultra carries an IPX6 water-resistance rating, helping protect the bike against splash-prone outdoor riding conditions.
IPX6 does not mean the bike can be submerged. Avoid deep-water crossings, pressure washing electrical components, and other situations that could expose the electrical system to excessive water.
