The MIC is the non-profit industry trade association that coordinates motorcycle manfacturers.
Your Mileage May Vary (a lot)
Motorcycles are much lighter than cars, but they also have much worse aerodynamic drag numbers than cars. Motorcycles are not fully enclosed bodies like cars. Stops and starts don't affect the range nearly as much as speed. The faster you go, the drag increases with the square of speed. In other words, if you double your speed, the drag increases four times. This causes the range of an electric motorcycle to be much worse at highway speeds than city driving.
The other factor that affects the range is the efficiency of the motor, controller and battery. When high current is required, these components waste a lot of energy giving off heat. Pushing through the wind at 70 mph takes a lot of power on a motorcycle.
City driving is made even more efficient by EV regenative braking. This just adds to the difference between city and highway range numbers. In general, consumers don't expect that the range difference between city and highway to be in the opposite direction compared to gas cars. Furthermore, they do not understand why there is a vast difference in those range numbers.
The lesson here is that range and speed numbers cannot be separated. Headlines that claim over 100 miles of range do not tell the whole story.
Real World Range
Simply State The Range At 30 and 70 mph
Motorcycle riding is about having fun and that means spirited riding. The MIC test does not account for spirited riding. An electric motorcycle is eco-friendly and economical, but it should also be fun. You need to be able to pull away from traffic at stoplights and zip around cars without worrying about how it affects the range. The electric motorcycle industry has to come up with better standards that reflect real world motorcycle riding so buyers can know what to expect.
6-7 Miles Per Kwh
100 Miles Real Range is the Goal
Is The EPA UDDS Derived Range Test Realistic?
The EPA understands that it's not a realistic test for gas cars so they reduce the UDDS mileage numbers by 10% to better reflect real world gas car driving. Recently, the EPA has made an effort to make electric car range tests more accurate. The range test results are reduced by around 30% to better reflect real world electric car driving. As far as we know, the electric motorcycle industry doesn't make the same or any effort to adjust the range numbers to better reflect real world electric motorcycle riding. Given the aggressive riding style of most motorcyclists, an even more aggressive reduction would be appropriate.
The Highway Test for an electric motorcycle is something that is in development. One manufacturer has created a highway range number that is derived in part from the UDDS City Range number. When you look at the formula that they use, you can see how it has a very low average speed, but is touted as a highway range. In this case they report a Highway range of 63 miles, but from their own data you can see that the electric motorcycle only went 45 miles at 70 mph. In other words, you can only ride for 38 minutes at 70 mph. This is the same vehicle that proudly reports a 114 mile City range rating.
