Set up your bike so nothing hurts

Why fit comes first

Almost every ache that follows an indoor cycling class traces back to one thing: a bike that was never actually set up for the person riding it. Knee pain, a sore lower back, and numb hands on the bars are usually a fit problem wearing a soreness costume. The bikes on Riverside are set up with you, not for you in the abstract, which means the four adjustments below get dialed in on your own body before the class starts, not guessed at from a chart on the wall.

None of this takes long. A full fit check runs a couple of minutes once you know what to look for, and the desk will happily walk through it with you the first time. This is simply what to expect them to check, and what you can check yourself once you know your own numbers.

Seat height

Stand next to the bike and the seat should sit roughly level with your hip bone. Too low, and your knees do all the work through a short, angry arc. Too high, and your hips rock side to side to reach the bottom of each pedal stroke, which is where a sore lower back usually starts. The right height lets your leg reach nearly full extension at the bottom of the pedal stroke with a soft bend left in the knee, never a straight, locked leg.

A useful check once you are riding: at the bottom of each pedal stroke, your hips should stay level and quiet in the seat. If you feel yourself rocking to reach the pedal, the seat is very likely a notch too high, and it is worth stopping to bring it down before the rest of the class turns that rock into a sore back the next morning.

Fore and aft

This is the adjustment almost nobody asks for and almost everybody needs. With the pedal at the three o'clock position, your kneecap should line up roughly over the ball of your foot, not out in front of it and not pulled back behind it. Sliding the seat forward or back to fix this does more for knee comfort than another notch of seat height ever will, and it takes the desk about ten seconds to check.

Handlebar height

Handlebars set too low turn a forty five minute class into a slow burn across your shoulders and lower back, especially for a first time rider still getting used to the position. Raise them until your upper body can stay relatively tall through most of the ride. You can always come out of the saddle and lean into a sprint. You should never have to hunch just to reach the bars for an entire song.

If your wrists or hands go numb partway through a ride, that is usually a handlebar problem rather than something wrong with you. A small nudge up, and often a lighter grip on the bars once you notice you are white knuckling them, clears it up faster than stretching your wrists between songs ever will.

Cleat position

The bikes on Riverside take cycling shoes with SPD or Delta cleats, and where that cleat sits on the bottom of your shoe changes how your foot rides. Most riders want the cleat positioned so the ball of the foot sits over the pedal spindle, which is close to where cleats often ship from the shoe box but is worth a glance before you clip in for the first time. A cleat that sits too far forward or back changes how your ankle and calf absorb every pedal stroke, and forty five minutes is a long time to fight a small misalignment.

If you rent shoes rather than own a pair, the cleat position is already set and unlikely to be the issue. If you own your shoes and ride often, it is worth checking that position every so often, the same way you would check the tread on a pair of running shoes, since cleats can shift slightly with wear over months of riding.

When to ask the desk

Any time, honestly. Fit is not a setting you lock in during your first visit and forget about. Bodies change, bikes get shared, and a seat height that felt right in January can feel slightly off by summer. If a class ever leaves you with a new ache in your knees, hips, or lower back that was not there before, that is the bike talking, not your fitness. Come fifteen minutes early to your next class, tell the desk what you are feeling, and let them walk the fit back through with you.

None of this is a secret held by the instructors either. Ask before class, ask after class, ask mid ride if something feels off enough to matter. A studio that sets your bike up with you once should be just as willing to reset it with you a second, third, or fiftieth time. That is the whole point of doing it by hand instead of leaving you with a chart on the wall.
