Step through electric bike guide: who low-step frames suit and how to size one

What makes a frame step-through

A step-through frame drops the top tube low, or leaves it out, so the frame opens into a U between the handlebar and the seat. You stand beside the bike, step one foot through the gap and sit down. A regular high-step frame asks you to swing a leg up and over the seat instead.

• Step-through or low-step: the lowest frame. The Hiboy EX6F steps through at 15.7 inches.
• Mid-step: a sloping top tube that sits between the two. Easier than a high-step, but you still lift a leg.
• High-step: the classic diamond frame with a level or gently sloping top tube.

Step-through frames used to be sold as ladies’ bikes. Today riders of every age and gender choose them for practical reasons, and they appear on commuters, cargo bikes, fat tire bikes and folding bikes alike.

Without a top tube, the frame needs extra bracing to stay stiff. Makers use thicker tubes or a twin tube design around the low section. The Segway MUXI, for example, uses a twin tube step-through frame.

Who a step-through electric bike suits

• Riders with stiff hips, knees or backs. Lifting a leg over the seat is the hardest part of riding for many people. A low step removes it.
• Shorter riders. With no top tube to clear, standover height stops being a problem.
• City riders with frequent stops. At a light you can put a foot down, or step off quickly, without leaning the bike far over.
• Riders in work clothes, skirts or dresses. No leg swing, and nothing in the way.
• Cargo riders. With a child seat, bags or a crate on the rear rack, swinging a leg over the back is awkward. Stepping through the middle is not.
• Households that share a bike. One low frame with an adjustable seat post fits a wide range of heights.

Older riders often gain the most from a low step. Our guide to choosing an electric bike for seniors adds comfort, controls and weight to the picture.

The trade offs

• Weight. The bracing that keeps a step-through stiff adds a little weight, and electric step-throughs are rarely light. The Hiboy EX6F lists 71.43 lb and the Segway MUXI 72.75 lbs.
• Lifting and carrying. With no top tube to grab, the frame is less handy to lift up stairs or onto a rack. Take the battery out first if it is removable.
• Car racks. Racks that hang a bike by the top tube need an adapter bar. A platform rack that holds the wheels avoids the issue, as long as it is rated for the bike’s weight.
• Heavy loads. A well built step-through rides solidly, but check the maximum payload and any rider weight limit on the listing. Our guide to the electric bike for heavy riders explains how to read them.

How to size a step-through

Standover height hardly matters on a step-through, so check these instead:

• Rider height range. Start with the maker’s range. The Hiboy EX6F lists riders from 4 ft 9 in to 6 ft 5 in, and the NAVEE Wolf X from 5 ft 3 in to 6 ft 1 in.
• Seat height. Seated, you should reach the ground with the balls of your feet, and at the bottom of the pedal stroke your leg should be almost straight. Smaller wheels, such as 20 inch fat tires, help keep the seat low.
• Reach. Sitting upright, you should hold the bars with a slight bend in your elbows. An adjustable stem or handlebar lets you fine tune it.
• Step height. The lower, the easier, especially with a stiff hip or a load on the rack.

The fit basics apply to every electric bike, and our guide on how to choose an electric bike covers them. If you sit near either end of a model’s height range, ask us before you order.

Features worth having

• A throttle for pulling away from a stop without a push off. Where you may use one depends on the class of the bike and your state and city rules, and e-bike classes explained sets out how the classes work.
• Front suspension or fat tires to soften bumps, since an upright step-through puts more of your weight on the seat.
• Hydraulic disc brakes, which need less hand effort. The Hiboy EX6F, Segway MUXI and NAVEE Wolf X list them.
• A removable battery to lighten the bike for lifting and to charge it indoors.
• A rear rack if you carry bags. The Segway MUXI and MUXI Pro list a 121 lbs rear rack load.
