Acceleration
 
How fast can you brave cyclists accelerate to 50 km/h or 31mph from a dead start?

I guess a velodrome would be the best way to test yourself. However a flat road with little wind seems more realistic for most SS/FG riders. Round to the nearest 1/10 of a second.

Also, include your gear ratio.

Good luck.

May I draft a bus?

I doubt I've ever gone 50km/h on my fixed gear to be honest. :lol:

1.4s
Little slower at the equator

Scientists estimate we're thirty years away from being able to accurately measure events that brief in duration.

It's okay, the most I've hit is 34.7 mph and that's going downhill, but Fixed is still relatively new to me, my cadence is not great and there as no such thing as flat around here :p

Okay, I'm willing to admit that asking for 1/10 of a second in precision is to accurate for most people to test themselves.

Otherwise, all it takes is a stopwatch. I timed myself today, 23 seconds.

It took probably 5 seconds to hit 40mph...




...going downhill.

Seriously though, spinning that fast sucks, and I would not do it again.

I have hit around 40mph + on a downhill with 48x16; spinning that fast is sometimes fun.

I do not know how long it would take me to reach 31mph from a dead stop on flat ground, though.

.1 seconds. My ass going from the seat to the ground while mtb'ing.
