Find your balance point. Know before you loop out.

Wheelie Coach clamps to your handlebar in two minutes, learns the exact angle you can hold, and warns you about a third of a second before you go over backwards — without you having to look at anything.

Below your balance point — keep lifting.

SWEET SPOT

Your learned balance point — hold exactly this.

LOOPING OUT

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 stays accurate the whole way through.

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 works exactly like the real device — same balance tracking, same learning, same warning timing. Drag the slider and watch it react.

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, not renders

This is the real hardware going into the build — not a mockup, not a placeholder. Exact suppliers and part numbers stay private; what matters here is what each part does and why.

1.28" round display — same shape as the gauge in the build
Brain
Low-power microcontroller

Built-in battery charging and battery-level monitoring — no separate charging circuit needed.

Motion sensor
6-axis motion sensor

Low noise, low drift — the sensor the balance logic runs on through every pull-up.

Display
1.28" round display

Matches the round gauge shape. Convenience readout only — never load-bearing.

Battery
2000mAh rechargeable, protected

~8h runtime target. Protected cell in a rigid tray outside the clamp's crush path.

Mount
Aluminium quick-release bar clamp

Rigid, universal, fits 22.2/25.4/31.8mm bars. The whole 2-minute install.

Alert language

Three long beeps Fault — not measuring Stop relying on it

The three cues differ by rhythm, not pitch or volume, because rhythm is what survives wind noise and a helmet.

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. That's why it works on any e-bike.
