1. The Rides (July 9-15)

Changes in the tour schedule may occur at short notice. Please check the Club Calendar on the website, as well as your email, prior to heading to a start location. If a ride gets cancelled or changed, you will be notified by email, providing you have registered on it using the “Register” button.

Tour leaders are reminded to contact the Tour Director at: if any changes are required to their ride.

Full details on all rides can be found on the KNBC Club Calendar of rides and events on the KNBC website. The KNBC Calendar, containing the most up to date info on your rides, is located at

Please do not sign up for a ride if you do not intend to respect the speed level at which it is being offered.

As a reminder, the following table details the speed levels.

Please note: the speeds in the table is not average speed. It is speed which you can maintain on a flat road with no wind.

2. Wednesday Evening Mystery Rides

Please join us on Wednesday evenings at Centrepointe for impromptu tours of 90 to 120 minutes, followed by socializing at the Royal Oak pub. L1, L2, L3 L4 and L5 speed groups will be arranged at the start depending on turnout.

Registration not required. Simply show up and look for the fun loving group of KNBC cyclists.

Start = 6:15 pm behind the Royal Oak Pub 117 Centrepointe Drive.

Please Note: These are impromptu rides. As such, they are not formally organised and have no pre-determined leader(s) or routes. That's all part of the "mystery" and what makes these rides such a fun hit. They are also weather dependent. Generally speaking, if the weather looks very questionable, there is a good chance there will be reduced numbers (if any) of the tour leaders showing up to volunteer to lead a group.

Since they are impromptu, they appear as a standing entry in the calendar -meaning they are never really formally cancelled, because they are never really formally organised. Members are expected to use their own judgement in deciding to attend or not.

If you get there and discover the weather is not good enough for cycling, you can always skip the ride and go straight to the social part at the Royal Oak ;-).

3. Red Revert

Where is it implemented?

Red revert is implemented where a minor road meets an arterial road, there are traffic lights, and the minor road has embedded vehicle sensors. There are about 850 intersections in Ottawa that currently have Red Revert. This includes where bicycle paths cross arterial roads and there are traffic lights/embedded sensors.

How does it work?

When the embedded sensor detects a vehicle waiting on the minor road, it will trigger the beginning of a light change cycle at the intersection.

IF, after triggering the light change cycle, the vehicle can no longer be detected, then the light change is considered to be no longer necessary, and at the end of the cycle, the lights won't change. Pedestrian lights will still count down, and the arterial road may get a yellow and a short red.

IMPORTANT! If there is a pedestrian light button and it is pressed, then the lights *will* change, no matter what, for the pedestrian (Which is why I don't understand Tom's scenario... if he pushed the pedestrian button, the lights *will* change)

NOTE! This has nothing to to with the "3 yellow dots" indicating where cyclists should stand. The sensors can't distinguish between a car and a cyclist. The Yellow dots are just an indication of a spot that is guaranteed to be sensitive to a cyclist.

Why does it do this?

In many cases, a vehicle (including a cyclist) is turning right... so they trigger the sensor, then make the turn before the light changes.

Without red revert, the traffic in the arterial road would be stopped at a light when there is no traffic at all on the minor road. That slows traffic and frustrates drivers.

But why does it count down and not get cancelled right away? Well more cars may arrive on the minor road. And the lights on the arterial road may be synchronized to keep the arterial road traffic flowing and technology limitations.

Red Revert is not the only case the lights count down and don't turn green

It pretty common t have advanced turning signals, so the lights count down, and your light stays red while another part of the intersection gets an advanced green.

What to do?

Never, ever, assume a light is going to change! Never move into the intersection without being sure your light is green! (Ultimately people are complaining because they entered an intersection while their light was red, and Red Revert is not the only case where lights count down and you don't get a green)

Stay on the sensor until the light has changed.
