Idea for a supercheap ebike made from a repurposed vacuum cleaner motor, UPS batteries, rusted walmart bike, and electrical junk from home depot.

That seems like an excessive ratio for a 1kW motor..

Did you do the math?

Kw or hp is a derivative of being able to move a fixed amount of weight, a certain distance, within an allotted amount of time.

That's why torque is more accurate.

A diesel engine can have 300hp and 900tq. A typical gas engine is close to square. All hp graphs will have hp/tq conviene at 5250 rpm. A typical diesel might not see 5250, so hp is anemic, and tq is fantastic
