This Custom Motorcycle Proves That Choppers Will Live On In the Electric Era
What makes the King Current stand out is the attention to detail. Forcella designed and built almost everything himself—the battery housing, heat sinks, belt tensioner, brake adapters, fiberglass covers—you name it. This isn’t just an electric bike; it’s a handmade, one-man passion project that rivals the craftsmanship of high-end choppers….Read more

The Electric Dream: Sinecycles X Mellow Boards
Imagine riding on the open road with a Motorcycle, but it’s quiet. Instead of a loud engine you hear wind and you feel the sun. Birds and animals watch you fly by in curiosity because they didn’t notice you coming. As you lean back and silently ride toward the horizon you have that ‘bad to the bone’ feeling of being totally free. Read more

Her er den elektriske chopper Stilen er velkendt. Men Motoren er et rent stilbrud.
En stor del af charmen ved choppere, er langsomt dunkende eller tøffende motorer og sparsomme lydpotter, som delagtiggør omgivelserne i motormusikken. Derfor har det måske også taget så lang tid før en kætter har bygget en chopper med elmotor. Og Bruno Forcella, ejer af Sine Cycles, ønskede at skabe noget unikt. Og det er ret unikt. Read more

SineCycles adds Electric Power to the Old School Chopper
As electric mobility keeps on gathering momentum in the motorcycle sector, chopper manufacturers remain strongly attached to tradition, seemingly reluctant to deviate from the typical V2 engine configuration. Sine Cycles has veered off this beaten track by taking what appears to be a conventional custom chopper design and slotting in an electric powertrain. Read more

SineCycles builds Custom on Zero Drivetrain
Like the performance of the Zero, but have some issues with the style of the bikes? Swiss builder Bruno Forcella feels the same way though, Forcella’s motivation may have been more about simply loving the choppers. So much so, that he started up SineCycles, and put together a pretty unique custom build with some serious attention to finish and detail.

A Very Clean 100% Electric Chopper
The story of early electric motorcycles is very old and somewhat unclear (first patent for an electric bicycle application seems to be on September 9, 1895 in Canton, Ohio) and it took them more than a century to belong to our present. As soon as they become cheaper and more practical by offering a wider travel range than a daily commute, there is no doubt than their market share will increase at a very fast pace. Read more

In Switzerland, a custom bike builder at Sine Cycles used a Zero motorcycle’s drivetrain to give us a glimpse of what an electric chopper would look like.
