BYB Telemetry provides a desktop application for Mac and Windows, and a smartphone app for iOS and Android — both free with every kit. Run advanced analysis or download and review a run directly at the track. Plus, the auto tuning can help in proposing the next change.

Two products, one system

A desktop application developed for deep analysis. A phone app to review runs at the track. Both talk seamlessly to the same acquisition unit, and neither replaces the other.

The desktop software

What's included

One desktop application for Mac and Windows, with everything a suspension setup needs — connectivity, analysis, timing and tuning. The views below are a selection, not the whole of it.

On-board video, synced to the traces

The run's on-board video and its data move on one cursor. Scrub the trace and the footage follows, so a spike in the fork line has a piece of trail attached to it.

What the software does, in six jobs

The analysis views, grouped by what you are trying to find out. Read top to bottom, they are a session from start to finish.

  • 0255075100012345678Travel used (%)Time (s)JumpForkShock

    See the run

    8.2 seconds of a recorded run, 1000 samples a second. The fork peaks at 78% of its travel and the shock at 72%; the flat stretches at zero are the wheels off the ground.
  • Start

    Find the pattern

    One recorded lap at Livigno, drawn from the run's own GPS: 743 m in 01:13.839 through 4 gates. Point at any gate for its time. The quickest section is into gate 2 at 40.0 km/h, the slowest into gate 4 at 33.0 km/h — where a run is won or lost.

    Where the suspension spent its time, either side of one clicker. Drag the divider: the rear moves from a narrow band low in its travel to the middle of it, and the front stops taking the peaks the rear was not.

    Model the bike

    Eleven measured points from one bike's linkage. The ratio falls from 3.67:1 off the top of the stroke to 2.20:1 at bottom-out — a 40% drop, which is what progressive means: the further it goes, the firmer it gets. Step along the curve to read each point.

    Go deeper

    The same run against frequency instead of time. Position peaks at 1.6 Hz on the fork and 0.6 Hz on the shock — the bike moving on its springs — while acceleration piles up near 23 Hz, which is the trail surface rather than the rider.

  • Prove it

    The run and the footage on one cursor. Scrub the trace and the video follows, so a spike in the fork and the rock that caused it arrive in the same frame — which is what turns a figure a rider does not trust into something they watched happen.

Auto tuning

Auto tuning reads the recording and proposes where to go next on sag, bottom-out, compression and rebound — you make the change, ride again, and the next comparison says whether it worked.

  • where the bike settles under you, and the first thing to get right.

  • how often the travel runs out, and by how much when it does.

  • kept apart, because a fork that dives and a fork that spikes need opposite changes.

  • whether the suspension is keeping up with the trail or falling behind it.

You do not need to be an engineer

We made all the charts and views easy to read and fast to interpret. For everyone.

  1. Record a baseline

    One run, a trail you know, the setup you already have. Everything else is measured against it.

  2. Change one setting

    One. Change two and the comparison cannot tell you which one worked.

  3. Compare the two runs

    Side by side. Better, worse or no difference — all three are answers.

Map characteristics: the same lap, coloured by whatever you ask for. Try it! The Jumps view finds 11 on this descent — 5.8 seconds of the lap airborne, the longest jump 7.3 m, the hardest landing 9.9 g.

The mobile app

Capture, at the unit

The app is what you use between runs. It pairs with the unit wirelessly, so nothing comes out of a bag.

  • Connect and configure

    Pair with the acquisition unit and change its settings without a laptop.

    The BYB Telemetry app connected to a Telemetry V3 Pro acquisition unit, listing its firmware, serial number, mode and 1000 Hz sampling rate above a download button.
    Connected, with the unit's settings in front of you and a button that pulls the runs off it.

  • Download and manage runs

    Pull a session off between motos, and share a run with a rider or a technician.

    The BYB Telemetry app's run library, with recordings grouped into dated folders.
    Every run filed by the day it was ridden. Import, move and share without opening a laptop.

  • Set the leverage curve

    Enter the bike's shock and wheel travel and the app works out the ratio across the stroke, then applies it to the wheel it belongs to.

    The BYB Telemetry app's leverage curve screen: a rising curve of wheel travel against shock stroke, the ratio figures derived from it, and the table of travel pairs it was built from.
    The linkage, typed in once. From there the app knows how far the wheel moves for every millimetre of shock stroke.

Review before the helmet's off

The run is on the phone before the helmet is off — a summary first, then the same channels you would open on the desktop.

  • Instant summaries

    What the run did, with the map beside it, before you have taken your helmet off.

  • Charts on the spot

Keep the record

The words, translated

Suspension analysis has its own vocabulary. Here is the whole of it, in the words people actually use.

Position distribution
Where your suspension spends its time — too low, all over, or in the sweet spot.
Velocity distribution
How fast the suspension was moving, and whether the damping is set for the speed the trail is actually asking for.
Sag
How far the suspension sinks under your weight before you have hit anything.
Bottom-out
Running out of travel. Occasionally is correct; often is not.
High-speed compression
How the suspension handles a fast, sharp hit — a square edge or a root.
Low-speed compression
How the suspension handles a slow, heavy load — braking, a berm, a compression.
Rebound
How quickly the suspension comes back after it is pushed in.
Leverage ratio
How much the wheel moves for every millimetre the shock moves. It is why rear travel and shock stroke are different numbers.
Stack view
Every channel on one time axis, so you can see what happened together.
Suspension view
The fork and the shock plotted against time, so a spike and the moment it happened sit on the same line.
Map characteristics
The ridden line coloured by whatever you ask it for — speed, impact, or how fast either end was compressing or rebounding.
Lap timing
Gates drawn across the trail and the time between them, so a section you lost is a number rather than a feeling.
Comparison
Two runs against each other, so a setup change is a difference you can see instead of a memory.
Lap manager
Where the laps and gates you have drawn for a track are kept, so the next session is timed against the same lines.
Linkage simulation
What a different linkage would do to the same wheel travel, before anyone buys one.
Frequency analysis
Which frequencies the suspension is actually working at — the bike moving on its springs at the low end, the trail surface at the high end.
Video overlay
The data and the footage on one cursor, so a spike in the trace and the rock that caused it arrive in the same frame.

FAQ

Questions about the software

Do I need to be a data engineer to use it?
No. The method is record a baseline, change one setting, compare the two runs. Auto tuning proposes the next change, and BYB Tech runs an online course for anyone who would rather be taught the workflow than discover it.
What does the desktop software run on?
Mac and Windows. The analysis views, run comparison and the distribution charts are all desktop.
Is there an app for iOS and Android?
Yes, both. The app connects to the acquisition unit wirelessly, changes its settings, downloads and shares runs, and shows summaries, charts and a map view at the track.
Is the BYB Telemetry software free?
Yes. The desktop software for Mac and Windows and the app for iOS and Android are both free — no licence and no subscription — and they come with every BYB Telemetry kit.
Can I export the raw data?
On Telemetry V3 Pro, yes. Raw export and custom channel mapping are two of the differences between the two tiers.
Can the software open Chrono runs?
It can, at the margin. The BYB Telemetry software is built for suspension data acquisition and reads GPS-based lap and split times; Chrono remains the dedicated tool for configuring triggers and precision lap timing.

The software is the reason to record anything

It is included with every BYB Telemetry kit, on all four platforms.
