    Brake Honk and Gear Clicking

    Bought in 2022, have had it serviced twice for brakes honking. Hindsight is 20/20, should've spent a little more for Tektro brakes on higher trims. The gears click often and require you to shift up/down multiple gears to catch correctly. Cost to upgrade both is half the cost of what I originally paid for it.

    Get rid of those brakes

    Bought in spring 2022 in Tallinn,Estonia. Promax F1 brakes no good at all, frequent leakage problems, until replaced by vendor for free. Secondly, the promoted Specialized own brand mudguards leave very little clearance, so the debris and dirt picked up from forest or park trail after a rainy day will block the wheels pretty quick.

    Brakes were bad

    I got my bike and I was very exited. I love this bike. I use it to commute to work and it works beautifully. The only downside are the brakes. I don’t know if I got defective brakes or what but so far I’ve had to service them 4 times. The stopping power gradually goes down and a loud squeak happens every month or so. I use normal roads so this shouldn’t happen given that I’ve only had this bike about 3 months. I’m upgrading the brakes to a more reliable set because I almost had a serious accident. Other than the brakes I love the bike

    Decent bike, making noise

    After my first10 mile ride, this bike back wheel starts making noise. Second ride the front brake starts making noises. Got it on sales, maybe that’s the reason.

    Sirrus x 2.0

    I haven’t owned a bike since I was a teenager and recently got the itch to start biking. Tried out an old one laying around and it was so uncomfortable and just not a smooth ride. Grabbed the sirrus x 2.0 and it was such an incredible difference so smooth and comfortable.. gears shift beautiful. The color is awesome and I like the reflective feature for when I decide to ride at night. It glides over all different terrains nicely the road .. bike paths.. grass no issues. Overall it’s an amazing bike I love it

    Good bike for money

    Lightweight, good gear shifts, good saddle. Love doing evening rides. This was my upgrade from cheap supermarket bike I had to a real bike, can really tell difference from weight and ride quality. Still was not sure about drop bars so went with this hybrid

    Good commute/touring bike

    Good bike. I was looking for an affordable bike that already has hydraulic breaks for easier breaking, is on rigid fork, and only on a 1x grouping so i wont need a front derailleur. This bike fit the specs i was looking for. its perfect for bike commute and exercise. Especially if you're in the city. It's lighter than an mtb but not as light or fast as a roadbike so I'd say it's a good touring hybrid. It's good for in between when you want to take on roads but also a bit of gravel. I got this because the area im in has a mix of paved paths but also trails. The thick tires help it to be less susceptible to punctures unlike with a sleek thin wheel in road bikes. Was able to try it in a forest trail with uneven dirt road and it's kinda challenging to be on rigid coz you can feel all the bumps and has no suspension so definitely don't get this for that unless you're used to its handling. It just gets tiring for my palms/arms/carpal in the long run when i ride more than an hr or two continuously with a flat bar. But since i couldnt afford the gravel bikes with drop bars, this is already a good alternative for the price. Got it at around 620+tax+pick up fee totaling to 707$ Overall, good to get this if you're mostly commuting within cities, wants to exercise, or do a leisure stroll around the city.

    Love the bike and great service

    I ordered this bike online and picked it up at my local dealer. The process was seamless and I love the bike. I use it primarily for workouts on paved roads, but also on some packed dirt pathes.
