The Yozma IN 11 is the trick bike of the IN series. Its headline feature is a dedicated stunt mode: select the fourth riding mode and a one-tap Auto-Wheelie Assist function lifts and holds the front wheel, with the wheelie angle adjustable so a rider can dial it conservative while learning and open it up as balance improves. Nothing else in the Yozma range is set up this way, and it changes what the bike is for. This is a machine built around learning to ride on one wheel rather than around covering distance.

Backing that up is a 4800W peak mid-drive motor rated at 200 N·m of torque, fed by a 52V 27Ah lithium-ion battery. Top speed is 45 mph and range runs to roughly 55 miles on a charge, with a full refill taking about six hours from the 52V 5A charger. Four riding modes - Eco, Sport, Race, and Stunt - raise the available power in stages, so the same bike can be handed to a cautious rider in Eco and then unlocked as experience builds. A one-button reverse makes it far easier to back out of a tight line or reposition on a hill without dragging the bike around.

The chassis is built for repeated landings. A hydraulic front fork and a nitrogen-charged rear shock give the bike full suspension at both ends, hydraulic disc brakes are fitted front and rear, and the high-carbon-steel frame clears 200 mm of ground with a 43.3 in wheelbase that keeps the bike stable when the front end comes down. A 420 chain with 116 links drives the 14 in front and 12 in rear wheels, and the bike is rated to climb grades up to 40 degrees, the steepest figure in the IN series.

Practical details round out the package. An angle-adjustable dashboard means the LCD stays readable whether the rider is seated, standing on the pegs, or holding a wheelie. A full lighting system keeps the bike visible in low light, and a magnetic emergency switch cuts motor power instantly if the rider comes off. Yozma rates the bike for riders between 3.94 ft and 5.9 ft tall with a maximum load of 220 lb, and it arrives with the handlebars already fitted and the assembly tools in the box.
