Frame seems to have been welded at an angle.

To whom it may concern, I received a brand new bike a week ago and notice the back joint was welded on at an angle. I’ve previously had issue with brakes and bikes and am concerned that the welding is a problem if it effects my wheels and brakes. i would like to speak with someone who can replace the bike. Please email or reach via phone at [****] Thank you Nicole

Great value, easy to assemble, fun to ride

I’m not an avid cyclist, I’m just looking for a simple bike for short rides to town. This bike looks great and appears to be decently crafted. The price can’t be beat. This is the first bike I’ve bought for my self in 30 years. I was looking for something different so chose the fixie. As far as size I’m 5’-9” 190lbs and chose the large. Is not want to go smaller.

Welds are smooth and complete. The breaks are basic and effective. They require some adjustment out of the box. I had this road ready in about 20 minutes. Pedals are simple plastic. The seat is a bit hard so you may want to upgrade that eventually

Fixie review

Easy enough to assemble, and tools needed were included. The rear brake may need adjusting or tightening, but I’ve had no issues with the bike while riding - just a comfort / preference thing I’ve not set aside time to do.

Decent Bike

overall all pretty good bike just overall needed more simplistic manual in order to try to put it together had more chain issues and rear wheel issues as well no idea what caused them they randomly popped off (chain) and the rear wheel would slant to left and cause to slow signifyingly
