Nice!
Why did you go with this hub and not something like a QS205?
Are you using bike tires?

I am also finally making use of my stoba pack. It’s actually quite nicely put together. So I’ll try to keep it as is, just adding an xt60.

[Scepterr]

I got a crazy good deal on the wheelset, less than buying just the hub
using the tires they came with for now, gonna see how they are

[Scepterr]

Detection results if anybody is curious

decided to hook up sensors, everything works beautifully, hall and temp

motor wiring complete

Magura MT5E Disc Brakes

[Scepterr]

Brakes installed, that was quite the macgyver rabbit hole, double post mount adapter to space the caliper closer to the rotor, and double rotor to move the rotor to the caliper. It works

Magura MT5E and MDR-C 203mm installed

What kind of speed and range do you expect out of something like this?

[abusfullofnuns]

He hit 88 km/h last night. Haven’t heard from him since.

[Scepterr]

at 12S it maxes out at 35ish mph
at 20S, 50ish mph
don’t plan on doing much riding above 30, legal limit is 25mph around here
Range I don’t know, need to get some rides and wh/m data

[Scepterr]

figured out lighting wiring, that was a headache, still need to get flasher for turn signal and dedicated switch for DRL

lights

interesting stats, drl+high&low beam and tail light uses 40watt, drl + low and tail light 30 watt, drl and tail light 6 watts

[Scepterr]
