UltraTRX Electric Bikes Are Proven to Go the Distance
You may be considering an E-Bike as an alternative to rising prices at the pump. But buyer beware!
Most E-Bike manufacturers are making ridiculous claims about the distance per charge they can travel when distance can be mathematically calculated using this industry-standard equation:
The Battery’s Watt-Hours ÷ 25 = Distance
To Calculate the Battery’s Watt-Hours = Amp Hours (Ah) multiplied by Volts (V).
UltraTRX Electric Bikes are proven to go the distance. Both mathematically using the industry-standard calculation and documented proof out in the field.

Here’s The Proof in Our Field Test:
Our Folding Electric Bikes front battery starts at 8.9 and traveled 19 miles with a 210 lb man on the bike.
Switching to the rear rack battery and the folding bike traveled an additional 47 miles.
Total Distance Actually Traveled:
Front + Rear Battery: 19 + 47 = 66 miles
66 miles (67.54 was mathematical calculation)

UltraTRX Folding Electric Bike Front Battery Watt-Hours are:
10.5 Ah x 48 V = 504 Watt-Hours ÷ 25
Front battery:
Mathematically the maximum distance it should travel is 20.5 miles.
Rear rack battery:
24.5 Ah x 48 V = 1176 Watt-Hours ÷ 25 = 47.04 miles in distance.
Folding Bike should travel 20.5 + 47.04 = 67.54 Miles
Front Battery Starts: 8.9
Front Battery Finish: 27.9
Rear Rack Battery Starts: 27.9
Rear Rack Battery Finish: 74.9
Here’s The Proof in Our Field Test:
2-Front batteries on both E2-Grizzly and E2-Terminator:
Battery inside frame 17.5 Ah, Battery on top tube 10.5 Ah.
Start: 117.4 and Finish: 168.1 miles Total= 50.7 miles
Switch to Rear Rack Battery:
Start: 27.9 miles Finish: 74.9 Total = 47 miles.
Total Distance Actually Traveled:
Front + Rear Batteries: 50.7 + 47 = 97.7 miles
97.7 miles (100.74 was mathematical calculation)

2 – Front Batteries:
Mathematically the maximum distance it should travel is 53.7 miles.
17.5 Ah Battery inside frame + 10.5 Ah Battery on top tube = 28 Ah x 48 V = 1344 Watt-Hours ÷ 25 = 53.7 miles in distance.
Rear Rack Battery:
Add the rear rack battery 24.5 Ah x 48 V = 1176 Watt-Hours ÷ 25 = 47.04 miles in distance.
Full-Size Bikes should travel 53.7 + 47.04 = 100.74 Miles
Front Batteries Starts: 117.4
Front Battery Finish: 168.1
Rear Rack Battery Starts: 27.9
Rear Rack Battery Finish: 74.9
Versatility and Flexibility:
UltraTRX Batteries are removable so, depending on your desired use, if you don’t need the distance, you can easily remove a battery for a lighter bike.
