Item overview
Bicycle Pump adds damage and attack size to marked weapons. Its effect can also apply to eligible inflatable items; the recipient’s tags determine compatibility.
- Acquisition
- Available in the starting item pool.
- Weapon effect
- Increases damage and projectile or melee attack size.
- Compatibility
- Check inflatable recipients individually.
Strengths
- Improves damage and attack coverage through the same item.
- Can support multiple marked receivers when their types qualify.
Weaknesses
- An unmarked weapon receives no effect.
- Does not remove a reload gap.
Priorities
- Hover the recipient to confirm the pump is an active source.
- Compare another damage copy with a needed reload improvement.
- Recheck marks after merging or rotating a pump.
Builds and combinations
Bicycle Pump increases damage on marked weapons and enlarges their projectiles or melee attacks. It is available in the starting item pool. Some inflatable items can also use its size effect; check the recipient’s tags and tooltip.
A pump beside Pistol, SMG or AK-47 contributes only when the weapon lies inside its marks. Hover the weapon to inspect which pumps affect it. Wi-Fi Repeater can extend support connections when a direct selector cannot reach the intended receiver.
Damage support and reload support
A larger projectile can cover more space, but Bicycle Pump does not replace Yo-Yo’s reload function. Compare the gun during an empty magazine as well as during firing before spending scrap on another damage copy.
For the opening loadout, see the Pistol and Knife build. For an automatic weapon with a larger support package, see the Minigun build.
