    • Front Wheel / Back Wheel Hub Motors: 1250 Watt + 1250 Watt Motors, 48 Volt, 14 Amp Hour Battery. 2500w Total. Total 50 Amp output for maximum motor output; (Compared to other dual motor manufacturers whose BMS output is 30 Amps which is not sufficient for 2 motors using 25 Amps each.) (Wattage is calculated by Volts x Amps = 48 Volts x 26 Amps =1248 Watts)
    • Throttle: Handlebar Mounted Thumb Throttles.
    • Dual Display Pads: Handlebar Mounted Digital Display with 3 Levels of Power: Low-Medium-High. Each motor has a separate controller creating 2 separate electronic systems. This allows riders the option to choose one motor (front or back) or both depending on what they wanted to achieve in any situation. Plus, if one motor malfunctions they still can use the second motor to get to their destination; (No other manufacturer offers this feature, Patent-Pending.)
    • Dual Control Units: Dual Seat Post Mounted 26 Amp Controllers for separate electronic systems.(Some manufacturers offer this, however maximum Amp output is 15 – 17 Amp per Controller which minimizes power and torque.)
    • Battery: Slide-In Behind Seat; Battery has Sealed Poly Casing, Lithium-Ion Technology with High-Density SONY® or Panasonic® Cells with 1,000 Cycles. Featuring a Patent-Pending BMS, (Battery Maintenance System), with 50 Amp output for maximum motor output; (Compared to other dual motor manufacturers whose BMS output is 30 Amps which is not sufficient for two motors using 25 Amps each.)
    • Battery Duration: 14 Amp Hours, 24.8 Miles per Charge. (Tested with 210 lb. man riding). Optional 24.5 Amp Hour rear mount battery; (coming soon.) This will add an additional 1176 Watt Hours, and with each 750 Watt Motor will achieve an additional 25 Miles per Watt Hour, or 45 – 58 Miles per Charge. So using both Batteries 60 to 70 Miles per Charge is possible.
    • Charger: Long-Lasting 3 Amp Charger, Charge Time 4 Hours. (Use of a Quick Charge Charger is Proven to Shorten Battery Life.)
    • Optional Rear Rack (Additional): 24.5AH and 48V + Bottom Tube Mount: 14aH 48V = Total with both 38.5 aH. All UltraTRX Batteries have a 50 AMP BMS to push both 25 Amp controllers and Motors to the max (25 Amp Controllers each).
      Max distance mathematically calculated: 38.5AH x 48V = 1848 Watt Hours ÷ 25 Amp = 73.92 Miles per Charge; (You can expect 60 – 70 Miles per Charge.)
    • Weight and Packing: 85% complete.
    • Weight: 45 lbs.
    • Speed: Non-Pedaling Assist Maximum Speed 23-26 MPH.* Maximum Speed 26 MPH.

    • Distance: Non-Pedaling Distance Approximately 23 Miles at Steady Full Speed on a Single Battery.*

* Please Note: We use a proven mathematical equation to calculate distance per charge. Our 2022 models will be tested and confirmed in real-life conditions.
