Have you started a new thread for that build? Didn't find but the old klein thread.nutnspecial wrote: ↑Dec 17, 2017 11:00 pmWow that seems a pretty dam good increase for just a couple pounds of motor!!!D7500 has 66,65kV and 48,45Nm
other motor has 69,64kV and 26,5Nm
Imo it's too bad the bigblock and apparently (looking for confirmation) the d7500 have around twice the kV of BHT.
Low kV means you can get more power/energy from the voltage side of equation, which better suits the lighter motors imo, and also you can charge a HV battery of same WH much faster at recommend C-rates.
But still- it looks nice! Glad I found it for ya hahaha, keep up the good work!!
PS Izeman, watch for my new klein build. . . You will love it as a mid direct drive I think- the newer frame/geometry is quite nice to our old ones!
Unfortunately I have not been able to get a GPS top speed yet, it does seem slow and close to the BHT KV(after testing top speed it is quite a bit faster than the BHT)
kV should be determined WITHOUT load, because under load the RPM will drop.
Right and that has gotta be what we're seeing here. Double kV (if this is definitely BHT and not bigblock VS d7500), plus taller gearing should be going >70mph with adequate amperage!!because under load the RPM will drop
Thanks maddin that takes all the pita speculation out of it- I had no idea toolman had already gotten and tested one! Must read more of that thread.The measurements from the russia guy are true because toolman2 measured the same:

Agree and that's my take on things too. I hope we have battery tech in our lifetimes to do something similar to that rad jet hover board thing the ?french? dude came up with. One 10lb 'drone' that you can drive. . .I am going to get my batteries mounted in and try a good trail ride with this thing at 18s 24ah 12t/60t and see what I think before I waste time changing the rear sprocket, but if I want more power that will realistically be the only solution for me and this build. I doubt I will get into a two stage reduction...by the time I finish it they will have better technology out
If it would have lower kV it would just meen that it needs more volts and less amps for doing the same.
