If this is the bike at http://www.sebikes.com/bikes/cat/rad-series/big-flyer-29

Then it can’t be done. The frame and fork lacks mount points for disc brake callipers.

  • If it's that bike... seriously, who makes a bike with only a rear brake? That's possibly the dumbest design decision I've ever seen. – David Richerby Sep 29 '18 at 21:28
  • It's for people who want to do barspins and either don't understand braking or can't afford gyro. – ojs Sep 30 '18 at 7:02
  • I think it is not unusual for BMX bikes to have only rear brakes or none at all. There seems to be a demand for BMX bikes with large wheels, eg for people who are too large for typical BMX bikes, or those who rather cruise than do tricks. The bike mentioned in the question appears to be such a bike. – gschenk Sep 30 '18 at 16:36
