Flatbike Guarantee

You know what components you’d like on your ideal MTB. But first, you need the perfect frame to put them on. A CHANGE 833 folding mountain bike frame is a light, 5.5 lb aluminum hardtail frame with a superpower–it folds in half in seconds. So any car trunk can transport your bike out to the trails. And after your day on the mountain, you can enjoy your dinner and trail stories in peace, knowing that nobody is messing with your bike in the dark parking lot because it’s safely tucked away from view.

This double-butted, TIG-welded 7005-aluminum frame is the only folding frame in the world that’s certified for toughness and durability (ISO-4210). Your frame includes:

  • Frame with folding latches installed (under the seat, under the bottom bracket) and 31.6mm seat post latch.
  • Standard threaded pedals with a quick pop-off function — Choose among flat, SPD, MTB, or mini-MTB (which accepts cages)
  • Headset: Press-fit. Top:1-1/8″,Bottom:1.5″
  • Bottom bracket: Threaded 68mm
  • Derailleur hanger
  • Carry bag
  • Warranty card

NOTE (FORK): This is the same frame used for the CHANGE 811 folding rugged hybrid (with carbon fork) and CHANGE 812 folding mountain bike (with shock fork). Fork purchased separately. Either type of fork is appropriate for this frame, as long as it is a tapered steerer, and a “mountain bike” style fork.
