Find your balance point. Know before you loop out.
Wheelie Coach mounts to your bike in two minutes, learns the balance angle you hold, and projects your pitch 0.3 s ahead so it can warn you before you go over backwards — without you having to look at anything.
Below your balance point — keep lifting.
Your learned balance point — hold exactly this.
Past recovery — the alarm should already be sounding.
How it works
Measures through the lift
Most balance sensors get confused the instant you pull up, because the motion of lifting throws off their sense of "down." Ours notices that and ignores the confused reading until you're steady again, so the angle on screen is designed to stay accurate the whole way through (accuracy is a target; validation pending).
Learns you, not a preset
Every time you hold a steady angle for about half a second, that angle folds into a running estimate. No calibration, no menus, no number to type in.
Warns you before, not after
It looks at how fast you're tipping back and warns you about where you're heading — not just how far back you already are. Like a car's forward-warning system, not a rear-view mirror.
You never look at it
Ticks speed up as you approach. A heartbeat means you're in the pocket. A solid tone means brake. The screen is a convenience, never the thing keeping you upright.

Try the logic
The simulator below runs the device's balance-learning and alarm logic. It does not model the sensor filtering, so the real device will behave differently. Drag the slider and watch it react.
- Below balance — keep lifting
- Balance point — hold here
- Past it — loop-out risk
Lookahead is the one dial that matters most. Drag it to zero and the alarm becomes a plain threshold — notice how much later it fires.
This is a training aid, not a safety device. It can't prevent a loop-out, and if you go over too fast, there may not be time for any warning to help. Wear a helmet. Learn the rear brake first.
Real parts inside
This is the real hardware going into the build — every part sourced, not a mockup or a placeholder. What matters here is what each part does and why.
Built-in battery charging and battery-level monitoring — no separate charging circuit needed.
Low noise, low drift — the sensor the balance logic runs on through every pull-up.
Matches the round gauge shape. Convenience readout only — never load-bearing.
6 h minimum runtime requirement. Protected cell in a rigid tray inside the enclosure, which is designed to be sealed against splash and light rain (validation pending).
Aluminium clamp. Fits round handlebars from 22.2 to 35 mm using its included rubber inserts. Clamp bolt (4 mm hex) plus GoPro pivot bolt.
Charges from any USB charger or laptop. Overnight from empty; plugging in wakes it to show the battery level.
Alert language
| Sound | Means | Do |
|---|---|---|
| Ticks, accelerating | Climbing toward your balance point | Keep going, ease off as they speed up |
| Heartbeat, a double beat once a second | You're in the pocket | Hold exactly this |
| Continuous tone | Loop-out predicted | Feather the rear brake |
| Three long beeps | Fault — not measuring | Stop relying on it |
The three cues differ by rhythm, not pitch or volume. The design intent is that rhythm stays distinguishable through wind noise and a helmet; this has not been tested yet.
Nothing connects to your bike
No wires, no splices, no connector to your battery, motor or controller. A self-contained protected cell charges over USB-C. No electrical connection to the bike. It fits round handlebars from 22.2 to 35 mm — bicycles, e-bikes, dirt bikes and e-motos.
| Spec | Value |
|---|---|
| Angle accuracy (target) | Within 2° when steady, within 5° while lifting (being validated) |
| Warning lead time | Target: ≥250 ms of warning (being validated) |
| Runtime | 6 h minimum (design requirement, being validated) |
| Charging | USB-C, about 10 hours (overnight). Charge indoors at normal room temperature. |
| Fits | Round handlebars, 22.2 to 35 mm (GoPro AMHSM-001 clamp, rubber inserts included) |
| Water | Designed for splash and light rain only (validation pending) |
| Weight | About 130 g without the clamp (estimate) |
