Honest review

I ended up putting it together real fast... Maybe one or two things needs adjustments because of me, but other than that pretty good bike... If I had to say something negative or on the bad side, the gear selector for the front sprocket is sketchy because you got to find the sweet spot when going all the way up or else the chain will pop off. But you can come back down to catch a gear without having to get off in the middle of the road

Cool Bicycle! Plan to Adjust the gears.

This is a really cool bike. Expect to watch how to adjust gear shifting online and perform the adjustment. The factory does NOT adjust them for you. If you need the gears pre-adjusted, pay the teenager to assemble it for you (%26 then take it back to the store and insist someone competent adjust it for you).
