IZIP Alki 1 Step Thru
This item is currently not available.


Go the distance in complete comfort on the Alki 1 step-thru, a 21-speed hybrid comfort bike with a step-through frame.

Named after one of our favorite beaches in the Seattle area, the Alki 1 step-thru is focused on function, delivering the best of both worlds—a comfortable upright riding position plus narrower tires and larger rims for efficient, longer-distance city riding and commuting.

Made with a rack- and fender-ready aluminum frame and fork, the Alki 1 step-thru is lightweight yet prepared to haul both you and your gear. The Shimano EZ Fire Plus 7-speed trigger shifters offer 21 gears without ever having to move your hands, and the comfort saddle, no-slip pedals, and comfort grips will keep all your contact points with the bike comfy and happy. Distance, durability, comfort, quality, and great value all come together in the Alki 1 step-thru.
