Sprongle

Version 24.3

SPRONGLE | Experimental High-Speed Gyrocycle

SPRONGLE is an experimental high-speed gyrocycle built around one large wheel, active stabilization, independent wheel yaw and active suspension.

Unlike a normal motorcycle, SPRONGLE is constantly balancing itself. The body stabilizer keeps the vehicle upright while the suspension and wheel assembly move underneath its center of mass. At higher speeds, automatic steering restrictions help prevent the vehicle from violently overcorrecting.

Thanks to its one large wheel, active gyro stabilization and triangular design, SPRONGLE can climb slopes approaching 80° and drive across roads tilted up to roughly 85°.

It can drift, jump, climb, front flip and travel at absurd speeds.

It is basically a spaceship on a wheel.

Controls

W / S – Increase / decrease speed Space – Brakes / slow mode Beacon – Auto jump Horn – Small jump / front flip X – Accumulated speed mode X Hold – Disable automatic brakes Fire Action 1 – Boost Fire Action 2 – Horn Fire Action 3 – +50 km/h speed limit Fire Action 4 – -50 km/h speed limit L – Flood lights K – Warning lights

Speed Control

ANALOG (default)

Best for normal driving, drifting, off-road and stunts. Without throttle the vehicle constantly tries to brake. Maximum speed is based on the selected speed limit. Without boost you will usually reach roughly half of the selected maximum speed.

ACCUMULATED(enable with X)

Holds the speed selected on the left speed bar. DO NOT HOLD THROTTLE. Instead, tap W / S to increase or decrease the selected speed. Best for racing, long high-speed runs, or if you are tired of holding W.

SPEED LIMIT 0 + ANALOG

The vehicle will no longer automatically brake when throttle is released and can continue accelerating without a normal speed restriction. PAY ATTENTION TO YOUR SPEED AND BRAKES. The speed limit can occasionally spawn at 0 after respawning due to a glitch. If the speed limit is 0, the NO LIMIT warning will be active.

Interior Controls

AUTO TURN RATE – ON by default. Restricts turn rate at high speed.

AUTO MAX SPEED – ON by default. Automatically slows accumulated speed mode when necessary.

Steering Knob – Increase / decrease maximum steering rate.

Disable Automatic Brakes – Disables automatic braking.

Left Speed Control Board – +/-50 km/h speed limit.

Left Window Lever – Open / close canopy.

Left Red Lever – Power adjustment. 100% by default.

Right Lever – Park mode. Slowly parks the vehicle.

Right Switch Board

• Scanner – Enables scanner • Unlock Roll – Disables perfect roll stabilization. Can cause a crash. • Air Time Stabilization – Keeps gyro stabilization active while airborne. • Lock Wheel – Locks wheel yaw. Useful off-road but can cause slow leaning and oscillation. • Disable Automatic Suspension – Disables terrain-following suspension. Useful at high speed.

Warning System

CAUTION Pure information for the driver. Usually does not require immediate action.

• BREAKS OFF – Automatic brakes are disabled. • WHEEL AIR – Wheel has no contact with ground. • LOW POWER – Power is set too low. • TURN RATE – Turn rate is at max. • HIGH SPEED – Speed is too high for high angle turns.

WARNING System warnings which may cause instability or a crash if ignored. Also activates the orange windshield warning blinker.

• NO LIMIT – Speed limit is disabled / set to 0. • WHEEL AIR – Air time is beginning to affect handling. • TURN RATE – Turn rate is at minimun, hard turns are impossible. • DRIFT HIGH – Wheel is sliding sideways. • HIGH SPEED – At this Speed breaking will take considrable distance.

DANGER Serious danger which can cause a crash if not addressed. Also enables automatic braking.

• HIGH G-FOR – Extremely high G-force. • VECTOR ERR – Movement direction differs heavily from facing direction. • FREE FALL – Vehicle is fully airborne and falling. • HIGH ANGLE – pitch / roll angle is too high for wheel. • OSCILATION – Rapid unstable side-to-side oscillation. • HIGH SPEED – Speed is too high to slow down at all.

CRITICAL Highly dangerous situation which will likely cause a crash or complete loss of control.

• FREE FALL – Severe uncontrolled airborne state. • WHEEL LST – Main wheel lost / catastrophic wheel failure. • STAB ERR – Stabilization system cannot keep up with whatever your doing. • HIGH SPEED – Beyond max speed the system was designed for.

Speed Guide

50–150 km/h – Good for city driving and drifting 150–200 km/h – Good for off-road 200–400 km/h – Good for highways 400–600 km/h – Unsuitable for most roads with turns 600–800 km/h – Approximate maximum stable speed 800–1400 km/h – Maximum reachable speed

Author Note

SPRONGLE originally started as a joke after my friend bc_malice replaced the legs on one of my mechs with a wheel.

The resulting contraption was surprisingly fast, stable and extremely fun to drive, so I eventually decided to build an entire vehicle around the idea.

That became SPRONGLE.
