UltraTrek’s 2500 watt Electric Bicycle that folds up to compactly store in your office, home, boat, RV or even in your trunk. Our powerful front wheel fat tire bikes are one of the safest fat tire bikes on the market today! As you know most E-Bikes are either rear wheel drive or center mount drive, rear system.  This puts all the torque on the rear and as anyone ever going into the soft terrain like sand, snow, mud or over obstacles like curbs, stairs or logs. Also, with rear torque system at top speed when you attempt to turn you could easily dig the wheel in and cause a situation no one wants to be in. With ours, you just power through those turns. So with the power of combining 2 motors into both wheels we have created an unmatched experience. With the motor on both wheels, you can go through and over almost, if not anything.
