I like allmost every thing on this bike .The speed is sufficient .The craftmemship is above quality . Gears ,brakes ,tires ,all good items .Only thing is head light if you like to night ride an do it often then you no how important a very high end light is .For me it usually takes two realy good lights one I can point right down at front tire an the ten feet out an around it Other light to point down the road for what is about to be were you are . So this light allmost does the wheel light but don't come close to the down the road light .So I think if that is my only issue then this bike is a must buy if you get below 550 then your getting o an free shipping then your getting a very good bike for a fair price .other bikes that match the quality of this one go for few hundred dollars more from 7 to 1000 bucks so there ya have it I'm a 240 pound man whom is said to be rough on my stuff I see it different I believe that if a product is good well made it should be able to take a certain amount of hard use an this bike can an does I would tell my friends an my family if in the market give this Ancherr brand a good look all there bike look at to compare to any bike you choose look at there's two an if you buy one you won't be dissaponted .An stability is what I like the most very strong balanced bike an it was a simply as it gets putting together but for me it should be I do believe others with no experience if they have common sense an can read an there are viedos on how to I believe any one can do! The weight of bike maybe little heavy but I like that it's hard to have a really strong steredy bike with out losing a little on lightness but it's not bad at all .Ok function of bike it's handles an buttons are all adjustable so it things can be adjusted to your liking but right out the box I moved the bell an that it so give this bike a good look then buy it you will be happy .
