i really like the Haro but the first one is alot cheaper than the rest but i have never heard of that brand so im not sure if i would be getting something crappy. and how hard would these be to assemble because i will have to assemble them if i want to buy either of the bottom 2
The top one is a decent bike, those three are pretty much all on the same level. And assembly isn't too terribly difficult. I'd imagine that you won't have to be pressing any bearings, so that takes care of the hardest part.
I really like the bike the only trouble i have with it is the pedal axle is bent therefor it moves kinda slow. Another problem i have is the front wheel makes a rattling noise. I tightening the bolts on the rim does it but it when i tighten them to the point where it wont rattle then it wont move. The rims also have a sticker that says x rims. are those good rims?
If the spindle is bent, you should really replace that. For the god of your bike. And with the front wheel, take it off the bike, and tighten all of the hardware on the hub, not the axle nuts. And no they aren't exactly the best rims.
