First off, thank you @sofu for carrying these heavy ass things in person all the way from Asia.
Got these today, the box was a bit beat up but the good bits inside arrived safe and sound.
A little surgery will be needed for the motor phase connectors. Replace whatever this is with bullets:
I thought these drives would be the perfect fit for my road board, should be a pretty simple swap.
Good initial impressions, appears to be well built, way more rolling resistance in the motor than Carvons. I bet it’ll be barely noticeable once it’s weighted and rolling.
They’re not much wider than SRz rkp, maybe another 10mm?
May get started on it after the game tonight, updates to follow…
Sat night edit:
Swapped the drives on, super easy, setup went off without any issues using BLDC Tool. Setup to run FOC.
Took it out for a quick test ride, impressions are great.
1mph to 15mph (or so) feels nice and progressive, similar to the pull you get on a R2. But for some reason, to me, the speed from 10mph to 20mph (or so) is super strong and really punchy.
I bet this feel will improve when I recharge the battery, at time of this first ride it was hitting soft cutoff (39v).
Didn’t do any hill tests since it was hitting soft cutoff but will charge it up tonight and take it up some hills tomorrow.
I did not get this impression at all. I have my batt min -20 and it brakes HARD. Nearly flew off braking at speed. Need to also mess with full brake erpm to lock the wheels at a higher rpm. Will also have to tone down batt min to ease up braking a bit.
Now, I wish I could assure everyone the axles are good and tested. I’m about 150lb and I think it’ll take some serious shakeouts to decide if the axles will hold up with a heavier rider, on less than ideal roads.
But so far I’m super stoked about these. Might be replacing the rear mounted hk sk8 6354 satellite setup if additional testing turns out ok.
