If so, what's your range in mode 3 at 28 mph?

Also, can the motor actually keep that speed for the entire battery or does it overheat and slow down?

Thanks.

Don't have an Ohm but do have a bike that will do 28 mph and you will be using around 30 wh/mi to reach and come close to maintains that speed on level ground with active pedaling. So if you have a 500 wh battery you would get perhaps 16 or so miles of range, but here is an example from a ride I did to test the theory.

Pushing air past 23 or so becomes a big factor. Terrain, road surface, stops and starts all must be factored in. Averaging close to 20 mph is more realistic and potentially almost double your range as per this example which also included a good amount of elevation gain/loss

So to answer your question somewhere in that neighborhood!

Assuming we use the current model of Ohm Urban commuter ebike and plugging in the ebike's information to the ebike simulator website: http://www.electricbikesimulator.com/index,enmi.html

This is what you get: By clicking the "Range" button, the range vs speed window will appear.. At 28 mph your range will be 17-18 miles. But I doubt if the battery can maintain a 500 watt output nor the motor can continue to operate at 500 watts without overheating.

Playing with the simulator, you need to dial the throttle all the way up to achieve this and it will give you a whole bunch of information from range at the top left, to power and power consumption at the bottom right.

Ken S what size battery do you have to achieve the 100km range at 23-25 km/hr

Original discussion was about 28 mph, which is very different than 28 km/hr.

It's a good thing that Justin from Grin Technologies was able to sample the BionX D series. At the right lower table, you will see the range of about 16 miles, the motor does not overheat at that speed (63 deg C final temp). At the middle lower table shows that the battery is discharging at 878 watts, while only 84.6% of it is converted mechanical power.

Regarding the question about the battery able to produce enough power continuously without overheating, I don't know the answer to that. Maybe somebody can chime in and teach us about battery discharge capacity, C rating, and how to interpret it.

In mode 3 I can definitely get over 20 miles. My longest commute so far is a little over 20 miles and I switched between 3 and 4 on that ride. Even mixed in some throttle only.
