The new Jazzy EVO 613 is available with either the standard SLA U-1 batteries or upgraded Lithium-ion batteries. Both options delivery plenty of power, speed, and charge range. The Lithium-ion version will give you a faster charging time, sustained power performance, lighter weight, and a longer life. The look of the EVO is sleek and modern. 6 color options are available in a muted matte finish. Comfort and convenience come through in the EVO’s memory foam high-back seat which allows you to adjust your seat depth and go into a semi-recline. Good posture and proper positioning are achieved with the EVO’s height, width, and angle adjustable armrests. The highlight of the seat is its single post which allows the seat to swivel.
