Bicycle Engine Kits - Rock Solid Engines
they are just chinese motors.
they may do some mods to it, but at its core its a cheap chinese motor.
Rock Solid do not simply purchase from overseas manufacturers and on-sell products to end users. We do not know any other organization in Australia who disassemble motors and rebuild them before they forward the product onto their clients, Rock Solid Engines DO! That’s what we do for a living; we assemble and modify engine components.
Rock Solid Engines source our engines from China, and have extensively visited numerous manufacturers in person throughout 07/08 for thorough assessment. A casting manufacturer has been handpicked along with component manufacturers to commence production for Rock Solid Engines exclusively.
@mapbike australias expensive and the laws for motorized bicycles are ridiculous there as well, pretty sure OP is over there speed limit. rocksolid actually sells a detuned motor just because of that.
