I just completed 41.2 miles on UNI5. Total time–3 hours 47 minutes. Average speed about 10.87MPH. The first 28.1 miles were straight into a head wind. The last 13.1 miles were exactly the
opposite direction, therefor a tailwind. Relatively no side winds, as the wind was right in my face one direction, and at my back the other. Incidentally, the wind was strong enough to make a big american flag like you see at government building stand straight out. Any less wind, the flag would have sagged. So however many MPH wind speed that is.
My average speed in the head wind was 10.87 MPH. My average speed in the tail wind was 10.92. As you can see, not any significant difference in speed. Well guess what, I have ridden a Coker enough to know that in the same conditions I would have shown a greater difference in average speeds when comparing the 2 directions. Whether or not the speed on my Coker would have been faster or slower in whatever direction for the sake of this discussion is irreverent. The fact is that you are more exposed to wind on a coker than on a 24.
With that behind us lets talk about what is important. The above speeds are of little difference when compared to the same course ridden on my Coker under the same conditions. I have recorded some faster times on the same course with my Coker, however I was doing a bunch more ridding and was in much better shape
I have been a participant in endurance cycling for 10 years. Both road racing and recreational rides. I have completed eleven 200 mile rides. Of those rides, most were road races where a slight advantage over 9 or 10 hours made a significant difference in over all time. I discovered that the biggest contributor to effective endurance riding is energy conservation.
Lets take a look at endurance unicycling and energy conservation. By endurance unicycling I mean miles that are 75 or greater in 1 stage or 1 day. Any corrections or adjustments via poor road conditions, uncomfortable saddle, wind, or whatever that cause one to have to speed
up or slow down to stay balanced are the biggest contributor towards taking away from energy reserves . These corrections( even slight) over time significantly take away from your total endurance. The idea behind effective endurance unicylcing , other than your fitness level is allowing the wheel to roll at your desired speed ( depending on your vehicle and fitness level) without interruptions. You must develop the ability to enable the wheel to roll down the road in a smooth uninterrupted manner. Obviously though out your ride you will have to make some corrections for various reasons, but the whole idea is to minimize them.
The good news is that with practice it is possible to propel UNI5 down the road with no more ( or very little) effort towards corrections that the Coker. Particularly on smooth roads. What does this mean in the world of speed and endurance unicylcing? EVERYTHING! We can talk about differences in wind speeds at elevations, leverage, wheel size, or whatever, but the simple fact is that you CAN propel UNI5 over long distances, at very close to the same speeds as the Coker!
With this discovery ( or invention) future distance rides will be much faster! Most unicyclers that are in shape are able to travel
at faster speeds but are simply limited by whatever cadence is possible on their Coker. Some even go to shorter 4.5 or 5 inch cranks to effectively increase cadence. The most important thing we all must realize about cadences
is this.-- At a given wattage or effort-- an increased cadence is directly proportional to an increased heart rate. In other words, more energy is expended giving the same amount of effort (always measured with pressure or
watts at the pedal) with cadences above 95. 95 is the line at which benefits are lossed with faster caddences. This variable is
so well documented in the world of cycling that training rides at higher cadences (110+) are designed to target the heart and save from having to tap into other energy reserves.
By combining a 700C wheel with the same hub that is on UNI5, you are effectively reducing overall cadence by forcing pedal speed into an acceptable range, adding inches of travel per revolution rather than increasing
cadence. Needless to say, there are many Coker heads that are experienced and fit enough to travel at faster speeds but are limited to how fast they can pedal. Now we have a solution to the problem.
This hub is key to providing the unicycle world with a vehicle who’s speed is only limited by the riders level of fitness and fear factor. That is what we have needed since the sports inception. I see it as revolutionary.
Most importantly is that UNI5 is just as enjoyable as a Coker. It’s easy! People will look forward to using it. That’s big! Have fun and put this thing to the test!
