A timeless cruiser, reimagined for the future. The Maxim XS400 started it all, in a garage in Sandy, Utah, in 2010. Two motor sizes, three batteries, and the classic lines of Yamaha's 1976 slimline cruiser.

The structural adapter for the XS400, SECA and Ninja 250 is patented.

When the Yamaha XS400 burst onto the bike scene in 1976, it was an instant classic. The small-capacity slimline cruiser was the perfect bike for new riders seeking the thrill of the open road, or experienced riders looking for an easygoing chopper for a lazy cruise. It's also where Shandoka began: our first retrofit was a Maxim XS400, built in a garage in Sandy, Utah, in 2010. Now we're giving the XS400 new life. Choose from two motor sizes and three batteries to build a bike that matches how you like to ride.
Do you dream of owning a classic motorcycle without the hassle of maintaining an obsolete engine? Now you can. Shandoka has done the hard part and designed a battery and drive system that makes it easy to upgrade for years to come. Put in a bigger battery or a more powerful controller, or go all the way with liquid cooling and chill plates. Our shop partners know how to keep you safe with this much power. We aren't building e-bikes. These are street-legal electric motorcycles.
The Yamaha SECA 400 was a variation built for track and street performance, with a six-speed transmission for better mid-speed gear selection and a higher top end, and a smaller front tire for nimble track response. Our patented retrofit turns that popular geometry into a modern electric motorcycle with boosted power and improved weight distribution.
