Bike looks good, works well

Bike came pretty much as expected. It takes a little work to flip it to the fixed gear - according to the instructions you need a chain-whip tool to take the hub off, grease it and put the fixed hub back on. Haven't gotten around to it yet. I have the matte blue color bike. The paint job on the bike seems a little cheap in the creases (like a little thin on the coating), but it looks very good from a couple feet away. Actually kind of a head-turner. Very unique looking. Brakes are a little weak and the rear requires more squeeze than I would hope (needs some minor adjusting). Otherwise, it's a good commuter at a good price!

Aluminum is real!

My UH-1N Air Force Rescue helicopter is almost all aluminum, I worked on it 45 years ago, it is today still in service.don't worry about aluminum, get a helmet for your head and go ride.

Disappointed

The bike itself is a beautiful design but the crank didn't last a day , it stripped and the pedal came off and now is unrideable for $250 I don't feel like it should have broke so easily my son is only 13 and isn't that heavy to break it I'm debating on purchasing replacement parts wich would be another $60 cause I'm worried they will just break off again. My son's very upset he waited a long time for this bike .

Dank bike

She rides well. And seemingly robust a week into riding her. Weird sound when leaning the bike I'm still looking into. The brakes are not as good as the description made them seem so I'm still adjusting them until I can get the slack out of them. Still amazed at how much energy goes from the pedals straight to the wheels. 5/5! And great value for the cost. I would not trust riding a carbon monocoque with a 50lb backpack but I do this bike

Good starter bike

Components are cheap but what do you expect for a bike at this price. Overall happy with it
