would this motor work

[Quadranut]

Just want your best opinion here

Would this motor work on a vehicle ( total weight including rider ) of 300 lbs ? 48 to 72 volt cells up to 40MPH

Treadmill motors work, are usually free at the roadside, but they're very inefficient. The extra batteries needed will cost $$$.

suggestions ? Recommendations ?

this is a " from scratch" build. Frame ( tricycle ) work and mounting brackets for ALL parts are custom ( ability and tools to do yes )....... I just lack the experience with electrics.

Recomindations depend on your goals. A motor good for speed won't be best for hill climbing. A motor good for endurance racing wouldn't be best for power. A motor to be used in hot climates would be diffrent from one used in colder cliemates. Something built ro make short runs at high poutput would be diffrent from something ment to run foryears of service.

Whats your budget? what distance of range do you need, and can you top off the battery charge at work, or must the battery last round-trip? what top-speed would you like? Batteries are expensive (lithium) or bulky/heavy (lead/acid) so an efficient system means you can get the same range with a smaller, lighter, more compact, less expensive battery pack.

Since its a trike, you'll have lots of room for packaging. Most custom builders that are new to E-bikes are unsure of what they want, and after getting a build finished they immediately realize they want something different. I'd recommend starting with a TNC brushed motor about 500W/750W. The brushed motors are slightly less efficient than the common brushless, but the controllers are very cheap.

I would recommend the final-drive sprocket be an adapter to chainrings, so tooth-counts are easy to change until you are finally satisfied with the entire system design. Chainring shown is a 42-Tooth on a 20" BMX wheel.

Thanks for the chainring idea Spinningmagnets Range however is 40 miles and charged up at work NP. Budget is paycheck to paycheck 20 here 30 there ya know. Drunkskunk a comfortable combination of speed and range 40 miles @ 30 - 40 MPH TOPS is good for me of course 80 miles on the weekend however would be ideal.
