A bike that looks spot-on in the photos can still feel wrong after ten minutes in the saddle. Too stretched out, too cramped, awkward to step through or hard to balance at a café stop - those little fit issues quickly take the shine off a new ride. This guide will help you narrow down the right frame, riding position and setup before you buy, so your eBike feels right from the first ride.
With an eBike, fit matters just as much as it does on a regular bike. In some ways, it matters more. You may use it for the school run, the commute, a beach path lap, a grocery stop and a Saturday coffee run in the same week. Comfort is not a luxury feature. It is what makes you reach for the bike instead of the car keys.
Start with how you want to ride
Height is useful, but it is not the whole story. Two riders can be the same height and need very different setups because their leg length, torso length, flexibility and confidence at low speed are different. The kind of riding you plan to do also changes what “the right fit” feels like.
For relaxed coastal cruising, local errands and casual rides, an upright position is usually the winner. You can see ahead easily, keep weight off your wrists and put a foot down without fuss when you pull up at lights. Some riders prefer a slightly more forward riding position, particularly if they are used to a more traditional cycling setup, but it should still feel natural through your shoulders, neck and hands.
Think about your real trips, not just the dream Sunday ride. If your route includes stop-start traffic, shared paths, café queues and frequent hopping on and off, easy access and low-speed confidence should carry plenty of weight in your decision.
Measure your inseam, then use it wisely
Your inseam is the distance from the floor to your crotch, measured barefoot with your back against a wall. It gives a more useful starting point than overall height because it relates directly to stand-over room and saddle adjustment.
To measure it at home, stand in socks or bare feet on a hard floor with your feet roughly hip-width apart. Hold a hardcover book firmly up between your legs, level it as if it were a bike saddle, and measure from the top edge of the book to the floor. It is not glamorous, but it works.
Use that number alongside the sizing information provided for the bike you are considering. Treat it as a guide, not a verdict. Frame geometry varies a lot between styles, so the same height and inseam can feel quite different from one bike to another.

If you sit near the upper or lower end of a suggested height range, focus on the parts you can adjust: saddle height, handlebar position and the distance to the grips. Being in range is a starting point. Feeling settled on the bike is the goal.
Stand-over height is about confidence
Stand-over height is the clearance between you and the frame when you are standing over the bike with both feet on the ground. You do not need a huge gap, but you should not feel perched or restricted either.
A step-through frame is particularly handy for riders who value easy mounting, wear everyday clothes, carry a bag, find a high leg swing less comfortable, or simply do not fancy swinging a leg over a high frame several times a day. It is a practical choice, not a compromise. For many riders, it makes the bike easier to use more often.
A higher frame can feel familiar and planted for riders used to traditional bikes. The best choice comes down to comfort, preference and the way you expect to use it. If you are regularly stopping with cargo, parking in tight spots or riding in casual clothes, uncomplicated on-and-off access is hard to beat.
Get saddle height close before judging the bike
An incorrectly adjusted saddle can make a properly sized eBike feel ordinary. Too low and your knees stay heavily bent as you pedal, which can feel cramped and inefficient. Too high and you may rock side to side, overreach for the pedals or feel less secure when stopping.
As a simple check, sit on the saddle with one heel on a pedal at its lowest point. Your leg should be nearly straight without your hips tipping to one side. When you place the ball of your foot on the pedal to ride, that creates a slight bend in the knee at the bottom of the stroke.
Do not set your saddle based only on being able to plant both feet flat while seated. Plenty of riders prefer a slightly lower saddle for relaxed, frequent-stop riding, and that is fine if it remains comfortable. Others may prefer a different position depending on how they ride. There is room to tune the setup around your confidence and habits.
Your saddle should also be level as a baseline. A nose-down angle can cause you to slide forward and put excess pressure on your hands. A nose-up angle may feel like it is pushing into you. Tiny adjustments can make a surprising difference, so change one thing at a time and take a short ride after each tweak.
Check reach, not just leg room
Reach is the distance from the saddle to the handlebars. It is one of the most overlooked parts of eBike sizing, especially for first-time buyers focused on frame size alone.
When you are seated with your hands on the grips, your elbows should have a soft bend. Your shoulders should feel relaxed rather than pulled forward, and you should not need to lock your arms to hold yourself in place. If you feel as though you are leaning on the handlebars, the setup may be too long, too low or both.
An upright bar position tends to suit easy cruising, mature riders, returning cyclists and anyone who prefers a relaxed riding position. Some riders prefer a slightly more forward setup because it feels familiar from other bikes they have ridden, but it should still feel comfortable through the wrists, shoulders and neck.
Keep in mind that handlebar height and angle can often be adjusted. A bike that feels nearly right may only need a small setup change. A bike that feels dramatically too long or cramped probably needs a different frame style.
Frame size is only one part of the picture
Traditional bike sizing often centres on small, medium and large frames. That can help, but eBike designs do not all follow the same rules. Wheel size, tyre width, frame shape, seat tube angle and handlebar layout all change the way a bike fits and handles.
Wide tyres can add comfort and stability, but they may also make a bike feel taller or heavier to move around while parked. A longer wheelbase may take a little more room to turn in a tight apartment garage or crowded bike rack.
This is why it pays to consider the bike as a complete package. Can you lift it slightly to reposition it? Can you turn it around in your storage area? Can you get on and off in the clothes you actually wear? The right fit extends beyond the pedal stroke.
Choosing size when buying online
Buying online does not mean taking a wild guess. Start with your height and inseam, then compare them with the bike’s stated fit guidance. Look closely at frame shape, seat adjustment range and handlebar position. If possible, compare the measurements with a bike you already own and enjoy riding.
If you sit between recommended sizes or near the edge of a bike’s suggested fit range, compare the actual frame geometry, saddle adjustment range, handlebar and reach setup, and the riding position you prefer. If you are still unsure, ask for fit guidance before ordering rather than relying on a generic rule to size up or size down.
For riders who can visit Cooly Crew HQ in Coolangatta, a test ride gives you the clearest answer. For Australia-wide buyers, asking for fit guidance before ordering is a smart move. Share your height, inseam and the type of riding you have planned. Gold Coast roots, Australia-wide support means the conversation does not stop because you are buying from Brisbane, Melbourne, Perth or a regional town.
If you are ready to compare your options, explore the current Cooly eBike range and look at the frame style, riding position and adjustment options that best suit the way you plan to ride.
Use the first few rides to fine-tune your fit
Your first ride is not the final setup. Give yourself a few local trips before deciding anything feels off. Ride to the shops, stop a few times, take a gentle hill and notice where your body feels tension.
Persistent discomfort through the knees, wrists, hands or back is a sign to revisit the setup. Small changes to saddle height, reach or handlebar position can make a noticeable difference. If discomfort continues, consider speaking with a qualified bike fitter or health professional.
The best-sized eBike is the one you feel comfortable grabbing on a warm afternoon for a beach run, a quick milk mission or the daily commute. Aim for easy starts, relaxed shoulders and a saddle position that lets you pedal naturally. Get those basics right, and the bike is far more likely to become your favourite way to get around.
