Hi,
First and foremost I did not have an intention to win any race but only to demonstrate some important points and to correct some misleading articles in the forum and other publication.
We started a little late about 10.20 am on the 10th Sept, and the route took a lot of navigating effort , and so it was not exactly the same for all for one reason or other. The weather was beautiful, but it did rain and the wind was very strong when we got somewhere near to the end, and we did not like to ride on a very busy main road at night and we therefore finished at Bridgwater about 6 miles from Burham-on-Sea.
Myself and Nick have Cycleanalysts attached and the detail results shown below.
Ching + Torq 2 / Nick + Torq 1
Miles 110.56 / 98.41
Ah 37.11 / 40.9
Miles/Ah 2.98 / 2.41
Wh 1316.2 / 1521.3
Wh/miles 11.9 / 15.5
Mph Max 36.1 / 45.4
Mph Avg 14.9 / 15.6
Time 7hrs23m / 6hrs16m
I knew exactly was up and accomplished it. With 4 batteries I completed the course of 112 miles of very hilly terrain at an average speed of about 24 kmph / 15 mph. I don’t have the skill nor the balls for speed like Conal or Nick, I pulled the brakes on going downhill, 36 mph is enough for me. Actually, I was quite right in an earlier thread that eZee coasting downhill is just as good as the Panasonic, because we have freewheel in the hub motor and the drag is very very small.
My experience with the silk route was far more difficult, with some serious mountains to cross and not hills like these.
The fundamentals and basics of the electric bike. These I am trying to make clear here. It is about energy content like in your car fuel tank , you don’t expect to run the same distance with 2/3 tank vs. a full tank, of course 370 Wh of battery will do more than 270 Wh, and the efficiency with which it is done. Higher speed will require substantially higher energy once it pass the 12 / 14 mph mark.
eZee drive has an efficiency of 70 ~ 82 % over loads of 150 to 600 watts, and I doubt there is anything better over this range. The eZee motor hubs on the Torq 2, Forza and Sprint are able to deliver far higher torque (36Nm at 140rpm) and power (720 watts) than the Panasonic Drive.
Efficiency and power does not depend on whether it is pedelec activated by torque sensors or motion sensors or pure e-bike mode on throttle, or better efficiency could be derived from drive via the BB over hub motors. The energy required will be the sum of the human power + electric power for the work done. My energy sum accomplished the 110.56 miles provided by the 4 batteries + the body energy for a man of 58 yrs. There is also the need to know how to used the gears/sprockets on the rear wheel appropriately to get the most out of the system. With eZee you have a wide range of choices for the way you would prefer to ride. I would say the most successful rider is Andrew Grayland with his Torq 2, did 112 miles , and still have about 5 Ah left on his 4th battery.
Here we have left a benchmark, and hope in future there will be participants with other bikes to demonstrate what could be done. Actually the only other bike I am keen to take on is the US$7~8,000 Optibike.
The Jurassic 50 km test in Switzerland we have taken on the Flyer, Bionx, Dolphins and etc, and the Torq 2 crossed the finishing line first, and then 3 years of Prestigne rally, and various serious trekking events – London to Paris Poppy Day event by Ian with one leg, Minnesota to New Orleans >2000 miles by Quentin www.bigriverride.com , Melbourne to Sydney 1200 km Suitable Transport , 2000 km trekking in Southern France by Richard Peace, and my 2200 km of the Silk Route , were not convincing enough ?. Week after next I will be continuing on my stage 3 of the Silk Route from Xian to DunHuang. And we are planning on the Zero Rally Africa from Victoria Falls to Cape Town for 4000 km in 10 days with our Torq 3.
