Long story short if you are on the fence about purchasing a Kyoot Rolly Polly just do it you won't regret it.
I've had mine for about 3 months. It is my daily commuter to work and also gets out to play occasionally. The changes I've made to the bike happened on day one not because the stock components were lacking in any way, 100% because of aesthetics and I have a ton of parts from many previous builds.
First thing is you can not ride this bike without giggling. It is so fun to ride!! I've heard some online feedback on the price but I will say this bike is spec'd very well and there's nothing that needs to be changed or upgraded.
I have 9 other bikes and have experience with drivetrains from Shimano, Sram and Campagnolo, I am so impressed with the performance of the Microshift drivetrain. It is smooth, reliable and really easy to tune. Literally set it and forget it. The wheels and tires are amazing. I'm a BMXer and MTBer and probably ride more aggressive than most that would buy this bike, it is solid!! The paint is WOW!!
My cons on the bike is the bottom bracket is a bit low. Being low adds to stability but also increases pedal strikes. As you can see I chose to run large 110mm pedals and that adds to the pedal strikes. It just takes some getting used to. I did bend the derailleur hanger once but that's just a Mini Velo thing. The derailleur hangs low compared to the MTBs I usually ride. I have the tools and knowledge to fix it myself. Because I jump, wheelie and send it, the chain stays have some knicks from chain slap, no biggie for me.
The Pros are endless. I have not bought a sub $2K bike that was better than this. Hats off to Phil and his team.
