I have a Xofo XFV(K) 500W 36V, but running it on 48V and 20A controller. I think the motor is a copy of the more familiar Bafang CST 500W. I have it in a 28" wheel and it runs about 40km/h with my 95kg.
If I want another more quiet, stronger and faster bike, will this motor be a good choice or is the difference to low? Maybe on a 26" wheel. I was thinking of 50-60km/h top speed but will not drive that fast all the time. I have seen different graphs here but I am a little slow. What motor version and battery voltage combo would be the best for my needs? Maybe with a adaptto mini-e (if thats not overkill).
The motor is the same whether it's a 4T (Higher speed) or 5T (More Torque) or the 1000, or 1500w model. The idea being, to pick the power level you need or you'll end up paying for battery power you may not need (lmao
which if on a budget is important too. Either-way the graph shows the motor to be over 90% efficient @approx 1kw so if you only want 40 mph, then a 5t in a 26" is fine, otherwise go with the faster 4T in the 26" as I currently have, at 50-60km/h, you're unlikely to have any heat issues.
You also say you want
another more quiet, stronger...bike,
The quiet will also depend alot on the type of ESC you choose. The Sine wave controllers are much quieter than the Infineon sq wave type, Lyen 18fet that I use, BUT I like the low growl of the leaf with it, def suits the higher speeds it gives, and better than my near silent, turnkey Kayman Flash+ which does 25mph (eventually
on throttle alone, but without a sound to warn pedestrians in advance of my presence
which isn't always great. The strength you ask for, is here in this motor, but imo you also need a frame that can handle it's power well, plus Torque arms. It may not be a cromotor/qs, or even a MXUS but it's def "strong" enough... @least for me (And I accidentally went 61mph on a test drive, while tuning it
)
Having said all that, I'd recommend you get the 4T (standard) 1500w motor in the 26", run on either 48v or 52v batt, and a 50a max controller, that way it can all be bought 4 a reasonable price. Imo you don't need a mini-e, that is overkill (pricewise) on this, (but also quality, so shuld last you and be usable on later builds too,) Sabvoton units are sinewave too, and programmable, plus on aliexp, they're pretty cheap if bought direct from China. To date, based on users reports, I've no reason to think that they aren't quality units either, so if I needed a sine wave unit, that's what I'd prob get.
Whateva you choose, lotsa luck on ur build
