6Wh/km @ 60 kph !! Cx is everything...
On open roads without frequent traffic lights, I think its closer to 5.8 or 5.9Wh/km and it currently got a relatively slowish tire at the rear wheel (Big Ben 50-559). I have to do some further testing, but with some light pedaling (75W), 3.3Wh/km @ 40km/h, 4.5Wh/km @ 50km/h and 6Wh/km @ 60km/h isn't far from the truth. If the road goes even slightly downhill, it gets even more ridiculous.

What is its weight ?
About 38.5kg without battery, but with hood. I can fit three, used, 20s battery packs behind the seat, that together have roughly 2kWh capacity left and weight 5kg each. With tool bag, big Abus U-Lock, water bottles, two Radical velomobile bags with some stuff, it should weight close to 60kg. With one battery and about 120km battery range, close to 50kg.
Its an old, glass fiber, Mk2 version that should have weighted about 32.5kg (I forgot to put it on a scale before tearing it apart). The current, carbon fiber, Mk4 version weights 25kg.

The fatbike fork was badly made of soft metal.

After riding on it for a couple weeks(?)

Presumably the braking forces (even though I never braked hard during any of the commuting) slowly bent it backwards...and the motor isn't hooked up to anything yet.

So I used some clamps Chalo sent and built a tripleclamp fork out of old bike frame tubing, and the lowers off a crappy "suspension" fork, minus all the internals. It works way better, though it only has a regular bike wheel in it, as the clamps are only normal fork width, and I haven't built the modules to offset the dropouts from the fork legs enough for the rear hubmotor to fit in it.

2004 Santa Cruz Blur from Craigslist with Grin GMAC 10T kit w/ 52V 16.5A Hailong battery, Phaserunner & Sempu torque sensing bottom bracket.

Was going to buy a BikesDirect HAL5, one of the last full suspension bikes without thru axles in the back, but an e-s'er convinced me to keep checking Craigslist. This bike has a a non-tapered head tube, 68mm bottom bracket and quick release front & rear. 160mm rotors & 180mm is the max with I.S. tabs, but I think it needs bleeding and new pads more than bigger rotors.

Wasn't sure about chainline & BB spindle length, so bought a 115mm Shimano to try before ordering the Sempu. Didn't realize front derailleur was set up for 47.5mm chainline with original Hollowtech II/Octalink crankset. FSA Dyna Drive puts chainwheels at about 50mm, so since I can't get a torque BB in 110mm, I installed a Problem Solvers direct mount adapter made for Boost which is 3mm further outboard than their regular adapter (29mm vs 26).

Put 100 miles on it so far. If Sempu keeps giving me trouble, I'm going to try powering it directly from the battery. If that fails, I'll try a TDCM.

Suspension was set up for a 175 lb. person. I'm 230, but I set it up with 200 psi rear & 100 front so I get a little more sag & plushiness at the expense of bottoming out on big hits, but I'm riding on roads not trails, so I think I'll be OK.

This is a cheapo ebike converted to hopefully a nicer ebike. Started as an impulse buy of a 20" folding fatbike on amazon for $679. It was supposed to be a white one, so I got a $75 rebate rather than force the seller to ship a new one.

It's a 500W motor with 36V battery. 810LED display with 3 level PAS. I own a 26" fatbike, and expected this to be tiny, but the wheels were almost 24" in diameter. That's too big and the bike really isn't meant for off road at 60+ pounds.

Smaller tires for $80. Paint. Swapped in an air suspension fork for $120.

It was intended for my wife, who won't ride it. Says it looks like something the Gestapo would ride. I don't like it that much either, because it's 60+ pounds. I can feel it with pedal assist. My 26" fatbike weighs less.

Maybe I should put a POLIZEI plaque on the front fender. I do plan to change out the controller. Put in a PSWpower sinewave model to give a better feel for pedal assist.
