This Glerc Mars mountain bike is really nice. It was relatively easy to put together, even for me, who never put a bike together before. There isn't a lot to assemble anyway. The outside of the box does recommend to have the bike assembled by a bicycle mechanic, but I think anyone with excellent hand mobility might be able to properly assemble this. But, going to a bike mechanic is still the safest option. BTW, make sure you watch the video on how to put it together because the instructions manual that comes with bike shows TWO different models but neither one is actually this bike. At first, it was frustrating and made me think I was missing some parts but then I watched the video and it all made sense.
I was pleasantly surprised to find that the tires were already inflated. They did need just a tiny bit more air put in them though. The tires also feel really durable. They're nice, thicker mountain tires, not the thinner ones that almost look like they belong on a ten-speed. They also have good tread. They were really stinky of that new, rubbery, chemical smell though, as new tires tend to smell, so I had to haul this little beast outside to finish assembling because the stink was filling up the room.
The bike seems to work great and the ride is smooth. I haven't had any issues with anything (yet). I'll let you all know if that changes anytime soon. Overall, I think this is a really nice, stylish bike for any kid or very petite person.
