You know what components you’d like on your ideal MTB. But first, you need the perfect frame to put them on. A CHANGE 633 folding mountain bike frame is a light, 5.28 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. Your frame includes:

  • Black 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
  • Headset measuring 1 1/8″
  • Derailleur hanger
  • Carry bag
  • Warranty card

NOTE 1 (FORK): This is the same frame used for the CHANGE 611 folding rugged hybrid (with carbon fork) and CHANGE 612 folding mountain bike (with shock fork). Fork purchased separately. Either type of fork is appropriate for this frame, as long as it is a straight 1 1/8″ (non-tapered) steerer, and a “mountain bike” fork.

NOTE 2 (WHEEL SIZE): This frame is designed for 26″ wheels (room for fenders, etc), but several customers have upgraded it to 27.5″. It will not fit 29″ wheels.

NOTE 3 (BOTTOM BRACKET): Bottom bracket area is threaded. We’ve been using Shimano SM-BB52 bottom brackets on the CHANGE 611.

WHY GET ONE?

  1. Folding a full-size bike down into a trunk-sized 36 inches is awesome.
  2. You can stow away and protect your bike from tampering and theft after riding.
  3. There’s absolutely no need for a bumper or roof rack.
  4. Indoor storage makes shielding your bike from the elements easy.
  5. It comes with a handy carrying bag that also protects car seats and interior.
  6. It’s compatible with many components, so you can build your ideal bike.
