Very nice quality piece of

Very nice quality piece of equipment, maybe more entry level compared to other frame types, but suits my needs and ambitions, and proud to call it my own head turner. Overall a great product all round.

This one is a re-purchase

This one is a re-purchase as my previous sirrus was stolen. Smooth and simple. Looks great, rides fantastically. It's too bad it's so sought after thieves, but make sure you triple-lock it. My previous Sirrus lasted me 5 years with very little maintenance.

Would Recommend?: Yes!

EVERYTHING WAS WELL BUILT ON THIS BIKE.

Had a 2012 Sirrus. Frame cracked this past summer. My local bicycle shop dug up my warranty, and I was covered. I had to wait nine months to get it, and boy, was it worth it! I loved the frame and the way it rides. The brakes were exceptional! Moving from a 2012 Sirrus to a 2021 Sirrus was like night and day. For a commuting bike, it is perfect. Highly recommend this bicycle.

Great bike, horrible Promax F1 breaks

The bike and drive train are amazing. I got this bike so i could ride with my wife while she is on her Roll Sport. The bike and design are great. Comfortable even on 40+ mile rides. The only issue i have with the bike is the Promax F1 breaks. I have had the bike for about two months and all the bolts and screws on the breaks and levers are corroding. I wish they would have used Shimano, i would rather have paid the extra for better quality.

Loads of Fun but...

Had the 2019 Sirrus 1.0, and it lacked in the brakes. Loving the power for with this years new hydraulic disc brakes, but they have a slight rattle since they aren't tensed by a cable. Learning to ride a 16speed after 21 speed has been a change, but there is more power to be put down from this 2.0. Get new peddles asap!
