SKU: 2500w-E2 Cherokee Dual Motor Electric Bike-1 Categories: ,


Key Features:

  • With two 1450-Watt Bafang Motors and two 30-amp controllers, these dual-motor electric bikes will reach a speed of 38 to 40 MPH and have between the two motors 200 NM of Torque. The Battery Output has a BMS of 55 – 60 amps. Real-life testing shows a distance per charge of 97 miles.
  • A patent-pending, solid-state switching system to change between the three batteries.
  • ThermoTRX Battery Protection System: Batteries that are equipped with heat strips to maintain optimal temperature, (above freezing), for charging and discharging, extending the batteries’ longevity.
  • GenerTRX Power Generation System: using Disc Brake Rotor Rotating with Magnets and Coils for a constant charge into your Lithium-Ion Battery increasing your distance mathematically by 30% – 50%.
  • All manufactured parts for bicycles and e-bikes use 15-5 Stainless Steel on bolts, nuts and screws, which rust. See our examples. UltraTRX Electric Bikes is the only manufacturer that takes the time to pull and replace every bolt, screw, or nut possible with 18-8 Marine Grade Stainless Steel which will never ever rust. That is why our Electric Bikes will last forever.

  • Max distance mathematically calculated: 55 AH x 48V = 2640 Watt Hours ÷ 25 Amp = 105 Miles per Charge; Real Life Test was 97 Miles Optional Fold-Out Solar Panel: This comes with its own storage bag (15″ x 16″ x 1″) and fits on any saddle bag 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 produce 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 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, Saddle Bag or Backpack.
