Almost perfect
So i couldn’t give it 5 out 5 because of one small issue the bike has. It makes a small tiny squeak sound in the front tire. From reading other reviews everyone has the same problem. Besides that the bike is perfect! Love it and ride it everyday. Great buy.
Highly unique bike
Between the Cannondale Bad Boy, Quick, Treadwell, I’m glad to have selected this bike. The bike has a ASTM Category 2 classification, which means the bike is meant for both road and off road, but no jumps of more than 1 foot. I’ve upgraded the bike to make it an excellent gravel bike/commuter. Everything is very smooth. Lefty fork allows for more space for handlebar bags but does make fender installations more tricky. Only con in my opinion. As a 5’10” person, I chose large, but choosing medium would allow for seat height to be higher and allow for more saddle attachments.
Bike is amazing, REI assembly was mediocre
Had a similar experience to the user below me, when I picked up the bike I quickly realized that a somewhat sloppy job had been done when it came to the assembly. After buying some tools and lube/grease, and about 5 hours of YouTube tutorials later, I learned how to take care of some of the issues (brakes rubbing the discs, squeaky front hub, chain grinding against the derailler, etc.) So my rating is representative of the Cannondale product which is top notch, super fun to ride and an eye catcher. Definitely one the best bikes you can get for under a grand depending on your intended usage.
Excited to have bike, but received item scratched.
I looked forward to receiving the bike, however after item was delivered, I noticed very distinct scratch on fork. Very disappointed to spend the money I did, and receive item in this condition. Ruined the moment.
Bad Boy Lefty does it all.
I absolutely love this bike. I live in Phoenix, within blocks of South Mountain Park, the largest municipal park in the United States. I ride on trails there with mountain bikers, I ride streets, roads and bike paths with road bikers, it's a do anything, go anywhere bike. I love the uniqueness of the single fork, which draws a lot of stares or comments. Do I wish it had shocks? there are times when I'm in over my head in SMP when I do, but 90% of the time it is just wonderful.
The front hub cap squeak is real
I love this bike, but I don't know how it made it onto market... the front hub cap squeak is awful. It makes no sense and has no real pattern to it, which makes it even more infuriating. I should have believed the other reviews before purchasing, but I dismissed them thinking that it was an issue with the front disk brake not being put on properly. Nope. After trying to have it fixed multiple times, reading countless forums on the issue, I think I'll give up now and return the bike to REI. The squeak is too much, it makes me not want to ride the bike at all, and when I do I'm just waiting for the squeak to start - which it always does, on every ride, at some point or another. Once it starts, it doesn't stop either. Do yourself a favor and believe the reviews, hopefully you can avoid this frustration.
Great Stealth City Bike
I ordered on the internet without seeing the bike. I was initially given a 3 week delivery date. The next day it changed to 2 week delivery and was accurate. I'm 6'2" 190lbs and I bought a XL. It's a perfect fit with 2-3 inches of clearance when I stand over it. I wouldn't buy a XL unless you're at least 6'1". Overall it's a very nice frame with decent components. The brakes are very strong and responsive. The tires are excellent for the road with good feel and grip. The derailleurs shift more than good enough for recreational use. Comfortable rider triangle with not too much weight over the bars. Now for the bad news. The frame is a bit stiff compared to the chromoly bikes I'm used too. The seat is not brutal, but not comfortable either. I'm definitely getting a new seat ASAP. And lastly the front hub squeaks and you have to put WD-40 on it. With all that being said I still love the bike and highly recommend it. It puts a smile on my face whether I'm strolling, or going for a new lap time around the local velodrome. Mine arrived looking slightly used and scratched (suspiciously like a floor model). But when I called customer service to complain the rep. was very professional and courteous. I was given a fair discount and I'm very happy. REI has shown good business ethics and I will certainly shop there again. And believe me, I would have trashed them and/or the bike in this review if I had a bad experience.
Decent making short cuts through parks
Purchased the bad boy 3 no complaints it rolls the NYC streets great , that squeak coming from the front wheel few drops of tube ok front wheel where bolt is problem solved.... learn that from a guy on YouTube
For those who want something different.
This lefty is a lot of fun to ride and gets a ton of looks. The gearing and brakes are great for a commuter bike. Riding position, grips, and seat are comfortable. Micro shift drive train works great. The paint job is a wicked flat black that looks great in person. The rubber strip along the top bar is genius. Nice to be able to lean a bike again a car or whatever without it falling or scratching anything. The lefty fork is not just a gimmick, it makes the bike lighter and even able to change a tire or tube without removing the tire. However there are a few negatives. The stock tires are terrible, I have had three flats in one month from thorns. I dunno what the deal with these tires is, but seems to be a really common complaint. Chuck em in the trash if you buy this bike. Second is that if you remove the front wheel, you have to remove the front brake caliper, and re align it to put the wheel back on, so if you have remove the front wheel to put the bike in your car buy some of those disc brake chocks. Third is the squeak from the hub, mine only squeaks when moving the bike around and not riding. I have lubed the seal well, but still kind of annoying to have a bike this expensive squeak really loud. Last but not least the drop out isn’t very wide or flat, I pull a Thule chariot cross a lot and fabbed an adapter so the hitch doesn’t damage the dropout. The pros of this bike definitely out weight the cons and you get to ride something unique and fun.
I’m a bad boy
I brought this bike 7 months ago and it truly lives up to the hype, it’s an awesome bike, extremely light weight and durable for the streets... Definitely lives up to its name and it’s gets so many compliments...
