EDS - Bike Gear turns drivetrain geometry, tubeless pressure and spoke maths into precise, repeatable numbers, in the garage or miles from the nearest tower.
Try the bench belowGear inches, gain ratio and rollout in metres for any custom cassette and chainring pairing.
An interactive table mapping pedal rpm to speed across every gear, in km/h or mph.
Chainstay length plus largest tooth counts gives the link count for 1x and 2x setups.
Front and rear bar or psi from rider weight, load, rim width and casing, then adjusted for tarmac, gravel, mud or rock.
3-cross and radial spoke lengths from flange diameter, offset and ERD.
Keep fork and shock pressures, volume spacers and rebound clicks for every kind of trail.
Every calculation runs on the device, so basement workshops and remote trails are equally covered.
Flip between millimetres, inches, bar, psi and both speed units in a tap.
🚴 We are a small crew of riders and home mechanics who got tired of scribbled numbers on workshop walls. EDS - Bike Gear is the toolkit we wanted in our own back pockets.
🎯 Our mission is to make bike physics approachable: turn drivetrain geometry and wheel maths into clear, repeatable adjustments for anyone with a wrench.
⚙️ The app gives you gear inches, rollout, cadence-to-speed tables, chain links, tubeless pressures, spoke lengths and a suspension log, all working fully offline, in metric or imperial.
🏔️ That matters because the best ride is the one you dialed in yourself, and the trail rarely has coverage. Know your numbers, trust your build.
Measure twice. Ride once.

EDS - Bike Gear does not collect, store or transmit any data. Every calculation and log entry stays on your device.
None. The app does not gather personal details, usage statistics, location or device identifiers. Values you type into the gear, pressure, spoke or chain tools are used only to show your result.
Since we hold no information, we do not use it, analyze it, share it or sell it.
Anything you save, such as suspension setups, stays in local storage on your device. There is no cloud, no server and no sync.
The app contains no analytics, advertising networks, trackers or outside SDKs that could receive your data.
Because everything runs locally and offline, nothing travels over a network that could be intercepted. Your device's own protections keep your saved logs safe.
We collect no data from anyone, including children under 13, so the app is consistent with COPPA principles.
No accounts, no sign-ups. You can remove all saved data at any time by deleting entries or uninstalling the app.
If this policy ever changes, the updated version will appear here with a new effective date.
