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.

The Kentfield features a Series 1 6061 aluminum frame with disc brake mounts and rack and fender eyelets and fast rolling, multi-surface capable 700c wheels with either a standard horizontal top tube or a step-thru frame design.

The stylish CrMo BMX style fork has straight blades, disc mounts, and BMX inspired dropouts.

The Kentfield features upright seated hybrid geometry that mixes the upright position of a mountain bike with the efficiency of a pavement bike.

Wide-range, 1x gearing is simple to use and offers as large if not larger of a gear range than multi-chainring bikes of the past.
