Real world Bafang Ultra Range

[Aquaman]

Now that there are more and more bikes with the M620/G510 Bafang Ultra motor, I thought it'd be interesting to see what type average range people are getting.

I completely understand that there are a million variables that impact range, so I don't intend this thread to be too nitpicky on all that. But feel this would be a good indication for people looking at purchasing an ebike to see some numbers and determine if an Ultra bike would work for them!

I imagine a something like below;

Frame Type: i.e. Fat Tire, Commuter, Mountain bike
Tire Size/Type: i.e. 26x4 knobby, 27.5x 2.8 smooth, etc
Battery Voltage/Size: 48V/19.2a
Typical Terrain: Flat, Hilly, Mountains, Pavement, Gravel
Average Range: i.e. PAS 2 - 25 miles PAS 5 - 15 miles
Rider Weight:

Also weight of the person, type of tire (Stubby/smooth) they will all effect mileage.

Original Post edited! Thanks for the idea

You're introducing too many variables. What you're really after is average efficiency, expressed as Watt-Hours/Mile.

This can be a hard thing to calculate on some bikes. If you have an EggRider, it's easy since it gives you that number for each ride. For other displays, you may have to calculate it from battery voltage and miles ridden. Convert volts to SoC (state of charge) and then knowing battery capacity convert to watt-hours consumed and divide that miles ridden.

And I think what you're going to find is that which motor is being used is not the most significant contributor. Speed, weight (rider+bike), and elevation change will matter most.

Note also that "PAS level" may not say much as some people have reprogrammed their system to have lower output at the lower PAS levels. The default of 30% or so from most Ultra equipped bikes to far too much for on-road use for many riders.

think the more information the better. If you have a 60lb bike, 250lb rider and running on stubby ties tires on pavement the stubbys are going to create drag and you are will see considerably less distance on the same bike with a 140 lb rider with smoothies. I read somewhere that the stubbies can cause the loss of approx 5 miles per charge.

I agree, there are a lot of variables. I was just trying to get some general information out there for people that are looking at them. Not everyone wants to dig into actually watt-hours consumed and get scientific. While I personally like evaluating things at an intricate level, I'm just trying to get information out there where there's currently little data.
