Bike Hugger 

For the jumpers, BMX, and anyone else that wants to measure the big air they get, there’s the HangTimer that features a built-in tri-axis accelerometer (like sharks with freakin’ lazer beams) and records your air time. Doubtful I’ll get any big air on Bettie, my road bike, or folding bike, but junior hugger likes to jump and he thinks that’s cool.
