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, the maximum Amp output is 15 – 17 Amp per Controller which minimizes power and torque.)

    • Battery Duration:
      2 Batteries:
      Total 23.5 Amp Hours = 1128 Watt Hours – 45 Miles per Charge, mathematically. Future real-life testing results will be available March 2022.
      3 Batteries: Total 47 Amp Hours = 2256 Amp Hours – 90 Miles per Charge, mathematically.
    • 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.)
    • Optional Fold-out Solar Panel: This comes with its own storage bag (15″ x 16″ x 1″) and fits on any saddlebag measuring about the size of a laptop. The dimensions of the fold-out solar panel completely unfolded is 33″ x 43″. This output of the Fold-Out Solar Panel has been calculated both with measuring devices as well as testing in various real-life scenarios. The Fold Out Solar Panels produces between 1.5 Amps per hour to a max of 2.76 Amps per Hour.Testing in 60 Degree F temperatures on a sunny day in Hilton Head, SC fully charged the battery in about 5 hours. A test in colder temperatures on a cloudy day in Bend, OR took about 7 hours to fully charge the battery. We also found that the solar panel charged a cell phone at the same time in less than an hour. This makes this a great accessory to have on any Electric Bike with a Rear Rack and Saddle Bag or Backpack.
