Ehhh. Not very strong.
The Good:
Good for the price, good brakes, and lightweight.
The Bad:
Weak rims, weak frame, weak handlebars, to much drag on hubs, weak chain, weak cranks, not a very solid stem, and horrible brake pads.
Overall Review:
I would not recommend buying this bike if you're going to ride hard. I'd recommend this for beginners, or just an all-around bike.
