The recoil wouldn’t be that bad. Apparently the M1895 was loaded with 6mm Lee Navy at around 2,200J muzzle velocity and a cyclic fire of 450/min. That’s quite manageable. In comparison, the M249 is a shoulder mounted gun of 1,800J, 850/min. That’s 50% more recoil to manage without a bicycle frame to support the firearm.
Newton’s 3rd law.
Every action has an equal and opposite reaction.
Shoot the gun, and the bike will get pushed in the opposite direction and be hard to control.
