Well done Bafang that was a real test !
Unlike the annual ride up a hill in Bristol for the so called "World Championship".
Actually, the short Brisol climb gives a much more realistic view of the difference between the bikes and is more meaningful to the average forum member. I'll tell you why.
All the bikes in both tests are limited to 25 km/h, so no advantage there. Put a fit cyclist on any of the bikes and he can pedal above 25 km/h most if not all the time. In the Tour de France, they average well over 30 km/h for a 100 miles a day, and that includes climbs that would terrorise us. Racing round the Nurbourg Ring with a team of trained cyclists therefore tells you more bout the cyclists and the bikes than the motor system.
If you had watched the Bristol event, you would have seen that in most races, the guy that won was the one that got his power down earliest to get an immediate 10 meter lead. That's why a non-cyclist beat semi-pros. He simply opened the throttle and left the crank-drives with torque sensors trying to find the right gear. In most cases they caught up about about 75% of the way up, but by then they were nackered because of the extra efort they needed o catch up. With not enough energy to get the maximum torque on their pedals, they flagged and the non-torque sensored bike pulled away again. That's why a non-cyclist won. The bike that gets its power the easiest and quickest has the advantage on a race like that.
That's more meaningful than a load of trained cyclists racing around above the assist limit. I bet Team Sky would have trounced the lot of them in the same race on their bikes without any power at all. It would be nice to get the data of the actual lap speeds from that race.
Whatever race anybody does for electric bikes, you have to be careful about drawing conclusions from it. The more different races they do, the better because people learn things which drive development.
I can now do my hilly 37 mile circuit on my road bike at a higher average speed than I can on my electric bike. Let's say I put a 3v motor on it and a couple of AA batteries, so that you could call in an electric bike, and then raced myself round the same circuit on the two bikes. The road electric bike would win. Would that make it the superior electric bike? Would it be more efficient? Which one would you describe as the best?
