Most torque converters have a stall speed around 2000 - 2500 RPM. Which also happens to be the RPM range that your vehicle normally runs at cruising speed. At a lower speed you would be simply running a viscous coupling between the engine and transmission.
Then, thereâs the obvious choice: A dynamo attached to one of the bike wheels. (These devices in general are called generators, but when attached to a bike, a generator is traditionally referred to as a dynamo.
Dynamo hubs in general have improved out of sight in the last 5 years. The good ones generate enough power to run a very bright light with very little resistance. The charge is generated by running a series of magnets past each other.If you have a hub on itâs own and turn the axle it feels notchy.odern lights also have built-in stand lights so that once the light has been run for a while there is a built up charge that keeps the light on when the bike is stopped. There are a huge range of LED lights and we get many different ones in to order, but here are a couple we keep in stock most of the time.
