You have to remember, the radrover is an off the shelf bike that the guys at rad bikes customized with their choice of components. Motor, battery size and cells, fork, etc are all upgrades you won't likely get on another bike, even if the other bike is the same frame/look.
I have exactly the same ebike as radrover, but it is not from radrover.
And the ebike has already the new suspension fork - it's a TGS and not Mozo.
The Battery is also 48V and 11.6 Ah. But the motor is still Hengtai not Bafang.
@Steven A Bean Not the same bike. Our Radrovers are 750W. Amazon bike is 500W. Our Radrovers have 11.6 Ah batteries. Amazon bike is 10.4 Ah. Our Radrovers have a digital LCD display. Amazon bike does not. While there are some similarities (i.e. grips, shifter, frame geometry, tires, brand of motor, derailer, etc.), the Radrover is a much superior bike, despite it's flaws.
