I love it

Great bike brakes work well Looks awesome. I've already gotten a bunch of compliments on it. However, when I took it out of the box, only 3 of the gears worked. After taking off the derailer guard and taking the derailer off and Exercising it realizing that it was not working to its full potential, putting it all back together. Realizing that the the derailed gard was hanging it up or Bent. Straightening it out and resetting the limits. Tightening the cable in a little miscellaneous stuff on the brake. It works great.


I’m 6 foot tall and I sit right in between the crack of both seats. I should’ve ordered a one piece seat for my size.

Great extension seat

I love the extended seat cushion. My son can ride, and I can sitt back more when riding by myself. Great purchase.
