The Kentfield ST1 is the step-through version of our most-affordable Kentfield. Designed to be affordable, comfortable and reliable it’ll go the distance, every day of the week.

Our Series 1 aluminum frame is lightweight and responsive, and comes decked out with plenty of rack and fender mounts to suit your setup. There’s a Shimano 7-speed drivetrain, Vee Tire tires, Clark’s mechanical disc brakes and plenty of reliable Marin components.

Why choose a step-through bicycle frame? Traditionally designed for female riders wearing skirts, the step-through has evolved to suit anyone that prefers a frame that’s far easier to swing a leg over. They’re ideal for less flexible riders, slow-speed urban cycling and riders that need to load their bike up with bags or kids.
