Electric Mountain Bike with 500W Rear Hub Motor, 48V/13.5Ah LG Downtube Battery, Pedal Assist and Twist Throttle

The Core Pro by EcoMotion is a new breed of fat tire electric mountain bike. Featuring a powerful 500W brushless rear hub motor, paired with a 48V/13.5Ah downtube integrated LG battery, the Core Pro is a more like a monster truck than an e-MTB.

The 4-inch Kenda Juggernaut fat tires, mounted on double-wall aluminum rims, are built for all terrain riding. So no matter if you doing off-road stump thumping, digging into sandy beaches, or navigating urban jungles, the Core Pro will get you there.

More than ever, we demand that our electric mountain bikes are flexible and give us a wide range of propulsion options. In this regard, the Core Pro does not disappoint. You can, of course, ride it like a conventional mountain bike, utilizing the Shimano Tourney 7-speed drivetrain.

But when you're ready for pedal assist, the Core Pro offers 5 levels of PAS with cadence sensors, as well as a Class 2 half-twist throttle. As you get to know your Core Pro, you will find the sweet spot for every riding condition, combining pedaling, PAS and throttle action. And with 13.5Ah of charge in the LG battery pack, you'll get up to 65 miles per charge!
