Really easy to put together, the tools sent with it are kinda lacking but work, I did use my on tools. You will want to torque the handle bars clamps down harder than you can with just an allen wrench / hex key though.

I upgraded from a 19.2mah 48v bike with a top speed of 27-28, and completely underestimated the power of this bike and foolishly set it to the 3 speed setting and promptly did a wheelie for 10 feet and almost crashed, please do be careful and wear appropriate safety gear. There are upgrade kits that make it even faster but if it is your first time please just practice on the original setup.

The only real complaints I have is the headlight bracket is only secured with one screw at the base and wobbles terribly making the headlight bounce around. The last thing is the shock absorber that comes with it is a little too long and causes the chain to grind against the frame, I suspect the stock absorber is somewhere around 265-270mm so I purchased a 240mm 600lbs absorber and it gave me a half inch clearance to solve that, I do not believe this is a huge problem that would take away a star from the bike but it should be looked into.

Overall very pleased, bike rides great after the new absorber, arrived directly from China in a little over two weeks with the box completely intact, I ordered it during the free shipping and only paid the cost of the bike, really can't do better than that.
