General points

Since Sixthreezero and Firmstrong are two brands that are a part of the same company, it’s no wonder that they share many of their features.

The folks who make these bikes’ main focus is to create lightweight, durable, and easy to ride, regardless of your physical fitness levels.

This is what makes these bicycles a perfect option for casual riders and people who use their bicycles on a day-to-day basis.

For example, if you’re going to work by bicycle, having a bike from one of these two brands can be a great way always to be sure that you’re going to have a great riding experience and that you won’t experience discomfort when riding bikes to and fro work.

Of course, these bikes may not be the fastest around, but that’s not their purpose to begin with.

Since these are cruiser models, as their name suggests, their purpose is to offer you an excellent cruising experience.

Here are some of the most recognizable features of these two bike brands:

  • Large tires – Racing bicycles typically have thin tires that are built for speed and durability.

On the other hand, cruiser bikes typically feature balloon tires that offer the rider a comfortable ride, no matter the quality of the surface on which you’re riding.

That said, cruiser bikes aren’t built to be taken off-roading, but in situations where the road conditions aren’t perfect, you can rest assured that one of these cruiser bikes will be able to pull their weight, so to speak.

  • Lightweight frame – One of the most important aspects of cruiser bicycles would certainly be its lightweight frame.

The thing about this is, if the frame of a bicycle is lightweight, you won’t have to waste extra energy while riding.

Also, in situations where you have to carry the bicycle, such as boarding a train or a bus, having a bike with a lightweight frame can be a great way to avoid straining yourself too much when lifting the whole bike.

This is great for people who aren’t that physically strong and cannot lift heavy objects.

  • Large seat – Since the accent with cruiser bikes is on comfort and ease of riding rather than speed and performance, another boon to riders who prefer these bikes would certainly be the seat.

Cruiser bike seats are considerably larger than those you can see on a racing bike, for example.

Such seats give you a lot of support while riding, improving your balance and your ability to turn.

Of course, a large seat will feel comfortable to sit on, so you needn’t worry about getting buttock pain after a long-distance ride.
