RadRunner is a “utilty bike”. This bike somehow combines all that is good for other RadPower bikes into one ultimate car replacement. The 750W motor power available at a twisting of a throttle, 48V 14Ah battery delivering 45+ miles range, Kenda fat tires, integrated lights, in addition to step-through frame and 20” wheels and 300lbs of hauling capacity, RadRunner is a surprisingly powerful part moped, part cargo bike that will make you wonder how you could live without it.
There are some things left out on this bike in order to keep the cost down. First, there is no the digital display featured on other RadPower models, it is replaced by a series of LED light indicating power and pedal assist level. Also, this bike is single speed, so no seven-speed gear shifters. However, powerful motor in combination with a decent low-profile cadence sensors will make you realize you don’t actually need the option of shifting gears even on the incline. Of course it would be better to have a torque sensor instead of the cadence one, but that would also make the price higher.
If you still thinks gears are essential for this kind of bike, there is an improved (and more expensive) version of the RadRunner available for preorder, with 7-speed Shimano shifter and a back seat.
