Cycling is supposed to feel good

Fix sore knees, numb hands, and saddle aches in 10 minutes at home. Instant AI video fitting gets you into the comfortable sweet spot, while automated logs track component wear.

Bike and body in perfect sync

Most riders think sore knees, tingling hands, or an aching neck are just part of cycling. In reality, your body is simply fighting a setup that's off by a few millimeters.

Sore knees on climbs and long rides

You don't have bad joints or poor fitness. A saddle that is even 5–10mm too low compresses the front of your knee 5,000 times an hour. If it's too high, your hamstrings overstretch.

Tingly fingers and upper-body tension

If your palms go numb or your neck aches after 30 minutes, you're carrying too much upper-body weight. Handlebars set too far away or too low pinch sensitive nerves in your hands.

Constant shifting, chafing and soreness

Constantly squirming to find a good position? A saddle that is too high or tipped forward forces your hips to rock side-to-side on every downstroke, causing painful chafing and lower back stiffness.

🤝 An honest word about bike fitting

Do you really need a £250-£350 studio fit?

Let's be completely candid: an expert in-person bike fitter in a studio is irreplaceable if you are an elite racer chasing podium seconds, recovering from complex orthopedic surgery, or need custom footbed molding.

However, most cyclists don't need a £300 lab appointment to stop their hands going numb or knees aching. Most riders are simply riding outside their safe biomechanical window because their saddle is 10mm off. Bikerly gets you into the 85-90% comfortable sweet spot at home in 10 minutes - before you ever decide to spend hundreds on a professional studio.

What our riders say

From weekend warriors to century riders, see how getting into the comfortable window transformed their rides.

Best money spent

"Easily the best money I've spent on my bike."

"A local shop quoted me £280 for a studio fit, which felt crazy for my £750 endurance bike. Bikerly showed me in 15 seconds that my reach was way too stretched and my saddle was tilted back. Swapped a stem spacer and leveled the saddle. Completed a 60-mile club run on Sunday with zero lower back stiffness."

Dave M.
Knee pain relieved

"It took me half an hour, but the result is awesome - no more knee pain."

"I used to get a sharp twinge at the front of my knee every time I pushed on climbs, and I assumed I just had bad joints. Recorded a quick 15-second clip on my turbo trainer. Bikerly showed my knee angle was too compressed at the bottom. Raised the saddle 8mm and moved it back 3mm. It took me half an hour, but the result is awesome - no more knee pain!"

Sarah K.
Hand numbness fixed

"It's incredible what a 10mm saddle height difference can make."

"I've been riding for 4 years and always accepted that tingling, numb fingers after 40 minutes were just part of cycling. Turned out my saddle was 11mm too high, making my hips rock and dumping all my upper body weight straight onto my palms. Lowered it by 10mm as recommended, and it's incredible what a difference it made. Numbness is completely gone."

Frequently asked questions

Honest answers about AI bike fitting, our pricing, and how Bikerly gets you into the comfortable riding window.

No, and we don't pretend it does! A top in-person bike fitter can analyze physical asymmetries, structural foot collapse, custom orthotics, and past orthopedic injuries. If you are an elite racer or suffer from severe medical pain, a £250–£350 studio fit is worth it. But most recreational riders and weekend warriors don't need a lab appointment just to stop their knees hurting or hands going numb - they simply need their saddle and bars in the correct biomechanical window. Bikerly gets you into that 85–90% sweet spot in 15 seconds at home, before you consider spending big money on a studio.
Yes, you are who Bikerly was built for! Pro racers already have dedicated mechanics and team fitters. Everyday cyclists, commuters, and weekend riders often ride with saddles that are 15-20mm off, assuming that aching knees, sore necks, and tingling fingers are just normal fatigue. Getting into the right comfort window transforms your weekend rides from painful grinds into pure fun.
Yes, it is incredible what a 10mm difference makes! At an average cadence of 80–90 RPM, you pedal around 5,000 times per hour. If your saddle is just 10mm too low, you compress your patella tendon on every single one of those 5,000 strokes. Moving into the optimal window immediately takes strain off your joints and lets your muscles work efficiently.
You record a short 10–15 second side-view video of yourself pedaling on an indoor trainer, rollers, or during a smooth outdoor pass. Our in-browser computer vision tracks key body landmarks (hips, knees, ankles, shoulders, elbows), compares your joint angles against sports-science benchmarks, and provides clear millimeter-exact recommendations on saddle height, saddle fore/aft, and cockpit reach.
Just your smartphone camera, your bicycle, normal cycling clothing (shorts/bibs and shoes), and standard 4mm or 5mm Allen keys for making bike adjustments. To record, place your bike on an indoor trainer, rollers, or lean against a trainer/turbo while spinning naturally.
Yes! Every free account includes 1 full AI Bike Fit analysis session. You can upload a video, inspect your joint angles, and see how close you are to the optimal comfort window without spending anything. Upgrading to Bikerly Pro unlocks unlimited fittings, millimeter-exact prescriptions, and the Before & After comparison tool.
Bikerly Pro is just £11.90 (approx. €13.90 / $15.90) as an honest 1-Year Pass. It includes 12 months of unlimited AI Bike Fittings across all your bikes, exact millimeter adjustment prescriptions, the Before & After split slider, garage capacity for up to 100 bikes, and a 100% ad-free experience.
No! We believe in transparent, honest pricing. Bikerly Pro is purchased as a 1-Year Pass with a single payment. It never automatically charges your card at the end of the year - you remain in complete control when you choose to renew.
Yes, 100%. All AI computer vision tracking runs locally inside your web browser on your device. Your video is never uploaded or saved to any external server, guaranteeing complete personal privacy.
None whatsoever. Our computer vision model automatically detects your joint landmarks directly from normal video, eliminating the need for sticky dots, wearable sensors, or calibration boards.
Bikerly makes bike maintenance effortless. Connect Strava in one tap, and every ride automatically credits mileage to that bike and its attached components. You'll know exactly when your chain needs checking (0.5% wear), when tubeless sealant is drying up, or when brake pads need inspection.
Bikerly is a modern progressive web application that runs directly in your browser on phone, tablet, or desktop at app.bikerly.app without needing to download anything from an app store.
