Electric bike size chart: how to find the right fit for your height

Why electric bikes use a height range, not S, M and L

Regular bicycles often come in several frame sizes. Most electric bikes come in one. The battery, motor and wiring are built around a single frame, and the maker covers different riders with an adjustable seat post and, on some models, an adjustable handlebar.

That is why the listing gives a rider height range instead of a size. If your height sits inside the range, the bike can be set up to fit you. If it sits near the edge, read the seat height and handlebar height too, because that is where the fit gets tight.

For the bigger choices (class, motor, battery and frame style), start with how to choose an electric bike. This guide covers fit only.

Electric bike size chart by rider height

These are the rider height ranges the makers list for models in our catalog. Each figure comes from the product listing.

• Hiboy EX9: 4 ft 9 in to 6 ft 5 in. A commuter frame on 26 x 2.5 in tires.
• Hiboy EX6F: 4 ft 9 in to 6 ft 5 in. A folding low-step frame on 20 x 4 in fat tires.
• Gyroor EB262 and Gyroor EB263: 5 ft 1 in to 6 ft 2 in, with a seat height of 31 to 42 in and a handlebar height of 39 to 42 in, on 26 in wheels.
• Riding’times GT33: 5 ft 1 in to 6 ft 3 in, with a 34.8 in seat height. A moped-style cargo bike on 20 x 4 in fat tires.
• AOTOS FLUX X26: 5 ft 2 in to 6 ft 7 in, with a 33.5 in seat height and a 40.9 in handlebar height.
• NAVEE Wolf X: 5 ft 3 in to 6 ft 1 in. A step-through frame on 27.5 x 2.4 in tires.
• Hiboy EX11: 5 ft 3 in to 6 ft 3 in. A full suspension fat tire bike on 26 x 4 in tires.
• Gyroor C33: about 5 ft 4 in to 6 ft, with a seat height of 30.7 to 34 in, on 14 in wheels.
• ASAP Zebra: 63 to 75 in (160 to 190 cm), with a 35.4 in seat height.
• Speedway Riders Q3: 5 ft 6 in and up, on fat tires.

Maker figures, checked September 2026. Real range and speed depend on rider weight, terrain, temperature and riding mode.

Which models suit shorter and taller riders

Under about 5 ft 3 in: look at ranges that start low. The Hiboy EX9 and EX6F start at 4 ft 9 in, the Gyroor EB262, EB263 and Riding’times GT33 at 5 ft 1 in, and the AOTOS FLUX X26 at 5 ft 2 in. A step-through or low-step frame also makes getting on and off easier; see our guide to step-through electric bikes.

Over about 6 ft 2 in: look at ranges that end high. The AOTOS FLUX X26 goes to 6 ft 7 in, the Hiboy EX9 and EX6F to 6 ft 5 in, and the Hiboy EX11 and Riding’times GT33 to 6 ft 3 in. Tall riders should also check the longest seat post setting, since a saddle that is too low strains the knees.

In the middle (about 5 ft 4 in to 6 ft): most models in the chart fit. Choose by frame style, wheel size and weight instead.

How to measure yourself

Two numbers do most of the work: your height and your inseam.

• Height: stand barefoot against a wall and mark the top of your head.
• Inseam: stand barefoot with your back to the wall, feet about 6 in apart. Pull a hardback book up firmly between your legs, spine level, and measure from the floor to the top of the book.
• Compare with the listing: your height should fall inside the rider height range. Your inseam tells you how the listed seat height will feel.

A rough rule of thumb: on a regular bike frame you pedal with the saddle above your inseam height, and you tip the bike or slide forward off the saddle to put a foot down. On a moped-style bike with a bench seat, many riders prefer to reach the ground with the balls of their feet while seated.

Seat height, standover and reach

• Seat height: at the bottom of the pedal stroke your leg should be almost straight, with a slight bend at the knee. Too low and your knees ache; too high and your hips rock.
• Standover: standing over the frame with both feet flat, you should have some clearance. Step-through and low-step frames remove the problem.
• Reach: with your hands on the grips, your elbows should be slightly bent and your back comfortable. An adjustable handlebar, like the 39 to 42 in range on the Gyroor EB262 and EB263, helps here.
• Seat height ranges: a range such as 31 to 42 in (Gyroor EB262 and EB263) or 30.7 to 34 in (Gyroor C33) tells you how far the saddle moves. A single figure, such as 34.8 in on the Riding’times GT33 or 35.4 in on the ASAP Zebra, is the one to compare with your inseam.

Frame style and wheel size change the fit

Folding and small wheel bikes sit lower and feel shorter. The Gyroor C33 rolls on 14 in wheels and folds at the frame and handlebar stem; it suits riders who need to store or carry the bike.

Fat tire bikes on 20 x 4 in tires put you a little lower than a full size wheel would, and the wide tire adds stability. The Hiboy EX6F, AOTOS FLUX X26 and Riding’times GT33 are examples.

26 and 27.5 in wheels give a longer, taller bike that suits average and tall riders well. The Hiboy EX9, Gyroor EB262 and EB263 and NAVEE Wolf X are in this group.

Moped-style bikes with a long bench seat fit differently from pedal-first frames. Sit on the listed seat height figure, not the height range alone.

Rider weight is part of the fit

A bike that fits your height also has to carry your weight. Every listing gives a maximum load. In the chart above, the Gyroor EB263 lists 375 lbs, the NAVEE Wolf X 331 lbs, the AOTOS FLUX X26, Hiboy EX9 and Riding’times GT33 330 lb, the Hiboy EX11 300 lbs, the Gyroor EB262 275 lbs, the Hiboy EX6F and Gyroor C33 265 lb, and the Speedway Riders Q3 220 lbs. Remember that the figure includes anything you carry.

Fine-tuning the fit when it arrives

• Power off first and follow the maker’s manual for every adjustment.
• Set the saddle height, then check that the seat post stays above its minimum insertion mark.
• Level the saddle and slide it forward or back until your knee sits over the pedal when the crank is level.
• Adjust the handlebar height or angle if your model allows it, and tighten every bolt to the torque in the manual.
• Take a short test ride somewhere quiet and make small changes until it feels natural.

If something does not tighten or adjust as the manual says, stop and contact us. Faults covered by the maker are on our warranty page. Once the fit is right, protect it: our sibling guide how to lock an electric bike covers parking it safely.
