Got her put together last night and went for a spin (it was wet - it'd stopped raining but the roads were still quite damp, late, and I'd had a few drinks so didn't go far - maybe a 2 mile loop).
Holy crap, what a rush! I didn't play with each assist mode that much, but level 2 seemed like a good fit. I can see making it to work with no sweat if I ride there in S mode, and getting a decent sweat on the way home in level 1 or 2 (and sometimes eco). I'll play more tonight, get the brakes bedded in properly and everything tuned up just so.
Overall build quality/ QC seems very good.
* Packaging is stellar. Lots of styrofoam, handlebar attached. All you have to do to ride is put on pedals and the front wheel - front fender is a PITA to put on (see below) but most fenders are, and some won't use fenders.
* Pedals are actually decent. Welgo metal pedals with tread - I'd expected cheap binnable plastic pedals, this was a pleasant surprise.
* Kickstand is nice, and in a good spot.
* Rear fender was installed/ aligned correctly.
* Front fender was a PITA to put on. It looks like the bolt on the light is supposed to hold the nut while you unscrew the (preinstalled) light, and while you reinstall the light with the fender attached. The tabs to do so weren't, so I had to remove the light from the bracket. Juiced might wanna consider tack welding this bolt to the bracket, or some other securement method.
* Light is good for "be seen", not so much for "see". This is fine, I've got super bright lights.
* Rear wheel build is good, runs true and spoke tension is fairly consistent.
* Front wheel build leaves something to be desired. Not all that true, and spoke tension is inconsistent. I'll throw the bike on the stand tonight and address this.
* Drivetrain tuning is abysmal. This may be shipping related. I'll deal with this while the bike is on the stand.
* Battery is a pain to get in/out, but I don't plan on removing it often.
* Tail light choice could be better. It's a pain to remove the light to activate/change batteries and it only has 2 modes. If this was wired in to the headlight circuit and came on when the headlight does, it'd be better. This will get replaced. Again, I'm covered in the light department (though I don't have a rack mount light). A cycliq Fly 6 is probably replacing it, I haven't decided yet.
* Bell is a nice touch.
* With the wet roads, fenders did a good job of keeping me and the bike dry at speed.
Overall, my initial impressions are very good. I'll do some tweaks here and there, but out of the box it's a pretty good build and a great value.
