I was literally just looking at that one. This is why I am here though, I don't know much about the different types of electric motors or their controllers so I didn't know if it was suitable.

I just used this site "Calculate HP For Speed" using the numbers CoE = 1.2, Frontal Area, 10 sq. ft., 800 lbs, 80 mph, and got that it should take 41.94 hp to overcome air drag. I overestimated on all of those numbers to give me a worst case scenario. 41.94 hp converts to 30.85 kw. Assuming 90%...

The qs180 is rated at 8kw continuous? Think that’ll be enough for highway speed? I was thinking I’d need a lot more than that.

The goldwing transmission is built into the engine case so it’s not really possible to use the transmission.

Okay. Thank you! Any advice on the motor?

Cool thank you. 200 lbs should be workable on a naked goldwing once you subtract the heavy engine and gas tank, assuming the motor and other new additions aren't more than another 200 lbs. The stock goldwing was about 600 lbs and could carry a rider, a passenger, fairing, and saddlebags. If I...

Will do. Thanks.

Damn. I really appreciate all the info. Well I will probably have to postpone it then, but what kind of motor should I be looking at since that determines everything else. Also is it possible to build it with maybe 5kwh of batteries and very limited range initially and add 2 more modular...

Appreciate the info. Unfortunately, where I live, not going on the highway is a non-starter. You can’t get anywhere worth going without getting on a highway with at least a 60 mph speed limit with the speed of traffic being at least 5 mph more than that.

N A naked 1st gen goldwing weighed in at close to 600lbs wet. Minus engine w/trans, gas tank, quad carbs, etc is probably closer to 300lbs (educated guess). A lot more when you add back in battery and an electric motor. Isn’t weight more of a consideration for acceleration than highway speed...

So at 150wh/mile * 100 miles= 15kwh. I know more about motorcycles than electrification. How much weight / volume / cost should I expect for 15 kWh?

I don’t need too much range. 100 miles would be nice, but I’d probably settle for 75. For my commute I really only need like 15 - 20 total including running a few errands if necessary. I’m only about 5 miles from work. But there are some friends I’d like to be able to ride over and see about 30...

I’m considering building an electric goldwing using a 1st or 2nd gen frame (‘75-‘83). My thinking is that I shouldn’t have too much trouble fitting a powerful motor and plenty of battery once I take out the big engine, transmission, gas tank, etc. I could even do water cooling for the motor (and...
