The bicycle is great and for the price I really can’t complain. It’s just as good as some of the higher end models. Although you might want to put tire puncture resistant tubes or tires because it will get flat if you run over a thorn or sharp objects. Other than that I love my purchase and I highly recommend getting one. I cycle almost daily about 3 to 5 times a week. It’s a great way to burn some calories and stored up energy. This is my second purchase from retrospec. Also if you get one with gears have it adjusted at your local bicycle shop. So it rides smoothly.

Easy assembly, superior construction, outstanding performance.

This bike is simply wonderful when navigating the hilly terrain and wooded walking/biking trails of my North Carolina neighborhood. Every gear is essential to get a great workout when climbing steep inclines. The Atlas step-through small model is perfectly sized for my 5-foot-3 stature. I am 62 years old and a lifelong exercise enthusiast, but I haven't ridden a bike for many decades. The Retrospec brand brings new life and excitement to my daily routine with the assurance that my ride will always be safe, reliable, and pleasant while racing my DDR German Shepherd, Samantha!

I am loving my new Retrospec Atlas bike. Was easy to assemble, but came with a warped front disc which Retrospec promptly replaced. Took it for a fun 15 mile bike ride this morning. Definitely recommend!!

I would take a photo of my bike .. trust me . I loved it ! But it got stolen… great bike.. great when I had it . 🥲
