The cheapest step-through on the site: a cadence-sensor city cruiser with a throttle, Shimano 7-speed, mechanical disc brakes, 80mm fork, chain guard and turn signals with brake lights. Jasion rates the motor at 1200W, which the page's own feature copy labels as peak; no nominal rating is given. Battery 48V 11Ah with SDI 18650 cells; Jasion does not state watt-hours, so 528Wh is volts times amp-hours. The spec table calls the 26 x 1.95 tires "Fat Tire"; at 1.95 inches they are standard city tires, so the width is what is recorded. 28 mph top speed, no class stated. Weight 65 lb, not stated whether the battery is included. What's in the Box lists two fenders and a rear rack, although the same page also offers fenders and a rack as add-ons; the box list is what is recorded. Price read on sale at $699 against a listed regular price of $1,599.
