It’s probably obvious that the primary difference between 3 speed and 7 speed bikes is the number of gears. But, their designs are dissimilar as well. Our 7-speed bikes use what many riders would refer to as a standard gearing mechanism for a bike, which includes different-sized cogs placed externally and shifted by moving the chain via a derailleur.
A 7-speed bike is a great bike for a person who rides on tricky terrain. It’s main purpose is to let the bike adapt to rough conditions and accommodate inclines, bumps and other difficulties. On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill. Compared to a 3-speed bike, a 7-speed is preferable for a rider who travels on varying terrain.
Professional cyclists ride 7-speed bikes because they can adjust the cycle’s gears according to personal preference. A 7-speed bike takes a bit more effort to operate, but it’s pretty simple to get the hang of it when you know about, and embrace, the learning curve.
Like a 3-speed bike, a 7-speed comes with a few cons, which include a greater need for mechanical repairs if the bike is typically taken out on rough terrain. The structural complexity of these bikes mean that if one cog breaks, the entire bike would likely need to be brought in to get work done.
