Message from the oracle, Mr. Franklin.
Excerpt from page 61 of Cyclecraft, by John Franklin.
"Generally speaking, you are at your safest in traffic if you can move at speed comparable to that of the other vehicles. Increasing your cadence and sprint speed will allow you to achieve this more often, particularly at those places where it matters most - junctions with complex manoeuvring. It will also be easier to restart quickly in a low gear at traffic signals and roundabouts, and to get yourself out of trouble if you on a potential collision course." So when some motorist fails to give way right in front of you, it is John's advice that by going faster you can avoid the potential collision. I must be missing something. Is he suggesting that I must ride at 88mph, engage the flux capacitor and reappear next week? The times I've had to accelerate out of a potential accident scenario is difficult to estimate. In fact so few times over the past 20+ years, it's difficult to recall! In my experience, the two times I've collided with a vehicle that failed to give way, I am certain I would have been better off had I been riding slower. Then I see: "A good cadence to aim for is about 80, while a sprint speed of 32 km/h (20 mph) will enable you to tackle most traffic situations with ease." My goodness, perhaps my speed is too fast after all. If sprinting only gets John's pupils to 32km/h, I can only conclude that normally they ride at about 20km/h. Yes, I'm learning why John's pupils are so accident free. JS. |

I read some of a preview online. The guy seemed sensible enough for folks who need that kind of thing, but refers to "cycling" too much, which always bugs me. My washing machine "cycles"; I Ride Bike. So when some motorist fails to give way right in front of you, it is John's advice that by going faster you can avoid the potential collision.

Frank says - WRT my crashing - that a helmet is not the fix. (Well duh.) Having been right there for each and every incident, it's pretty easy to see that the fix would mostly be to ride more slowly. Then I see: "A good cadence to aim for is about 80, while a sprint speed of 32 km/h (20 mph) will enable you to tackle most traffic situations with ease."

JS. you need to have sense to take every situation as it is, not as directed by a book- but that said, the faster you go in traffic the less the closing speed between yourself and vehicles around you, you also enhance your safety at speed by moving into the middle of the lane to give yourself either left or right as a way out in event of an emergency in front ( cars can stop much faster than a bike). Persons who tend to ride at pedrestrian speeds need to stay nearer to the curb |

JS. you need to have sense to take every situation as it is, not as directed by a book- but that said, the faster you go in traffic the less the closing speed between yourself and vehicles around you If you ride faster, the closing speed to all perilous situations ahead is higher, hence in case of an emergency you are less likely to be able to stop in time, or swerve out of the way. The closing speed for the vehicles approaching from behind is certainly less, but that is not relevant to dodging the car that just pulled out in front of you. , you also enhance your safety at speed by moving into the middle of the lane to give yourself either left or right as a way out in event of an emergency in front ( cars can stop much faster than a bike). I agree that being out from the gutter offers more opportunity for an escape, but speed has little to do with where in the lane I travel. Persons who tend to ride at pedrestrian speeds need to stay nearer to the curb Oh dear. I think Frank Krygowski should respond to that... Frank? JS. (BTW, is Raamman your first or last name?) |

Yes, I'm learning why John's pupils are so accident free. Undoubtedly a trike that you can ride even slower without keeling over would be helpful too. I am shocked, SHOCKED, to see Krygowski relying on such a bogus source. But I can see why ****tard Frank thinks ****tard Franklin is a citable authority. Both are clueless and each needs the other for support. The colloquialism is "the blind leading the blind." They may even be well intentioned (I doubt it), but they are still blind. DR |
