The package was delivered in less than a week, with free shipping. Everything was beautifully packaged and well-protected. The front wheel was surrounded by styrofoam blocks, and the rest of the parts were inside another box next to the wheel. I am not using all of the parts so I cannot comment on everything.
Wheel: spokes are heavy gauge and the tension seemed fine at the time of installation. The hub is marked as 1000W and is able to accept a disc brake rotor. The rim has a nicely machined surface for rim brakes, and has rim tape installed to protect the inner tube. The tire is some kind of semi-slick with edge knobs, although I immediately removed this to use my Kenda Small Block 8.
Controller: Seems fairly standard. Presumably waterproof - the end covers have gaskets, and the cable grommet is all sealed up with some sealant. All connectors are colour coded and keyed - it should be impossible to connect the pieces incorrectly. The blue governor loop was disconnected by default on mine. I replaced the battery connection to a XT-90 connector. As others have mentioned, the frame bag is a little small for it - you can get the unit inside, but the cable bundle will stick out. I am just running the thing out in the open on a rear rack.
Twist throttle: push button on/off, and has three LEDs to indicate the battery level. I really like the simplicity of this as I did not want to install a display on the handlebar. A minor complaint is that the shape of the cable exits interferes with my Rapidfire shifter. I have my shifter moved severely inward now and it's a bit awkward to use, but it works so I am undecided if I want to replace it. I am not using the included grips as I am a big fan of ODI Ruffian lock-ons. I use the short version on the throttle side - highly recommended!
Pedal assist sensor: not used. This is a front wheel kit, and with the relatively lower traction of the front wheel, I want to be in full manual control of the throttle at all times. For example, pedaling from a standstill to initiate a turn on wet pavement will be very dangerous if the pedal assist was to kick in.
Brake levers: serviceable. Cutoff works well, the return is a bit weak. I might need to increase the return strength on my calipers. Length is for 3 fingers, these aren't Avids but I'll live with them.
Operation: I am running an unprotected 12S 8Ah hobby LiPo setup, so it is a bit undervolted (and a fire hazard) but still has plenty of power. Off-power resistance is hardly noticeable. Full throttle is bonkers. For a front wheel motor, use throttle in a straight line only! I have not GPS checked the top speed, but it is much, much faster than I can ride unassisted. Only minimal throttle is needed to assist with pedaling slightly above my normal riding speeds (even uphill), so surprisingly very little battery is used. For a pedal-assisted test ride loop about 4km with a few spurts of full throttle, I used less than 0.8Ah out of my battery, with individual cell voltage around 4.1V. The same battery in my former 500W e-scooter on the same route would drop the cell voltage to around 3.6V, though to be fair it was a much heavier machine with useless pedals just for show. I may even enable the speed governor, this has way more power than I need.
Summary: very well-performing kit at an incredible price. Put this on a cheap bicycle from a general sporting goods store with some hobby LiPos and you will have a decent and powerful commuter machine. This was more of an impulsive experiment for me, though now that I know what its capabilities are, I can definitely see myself replacing this with a rear-wheel kit in the future.
**update**
I have been using this almost every weekday for the last 3 months. It still works well. I have left it outside in the rain several times with the controller exposed as it is, and ridden it in the rain as many times. No issues whatsoever. Battery usage is very light. After about 2 or 3 weeks of use, 4km round trip, I use about 5000mAh worth of battery. Already planning on buying another one of these for a new project.
The only other warning I will add is that due to the width of the electric hub, not all disc brake calipers will work with it. I attempted to install a ZOOM Xtech HB-100, and the caliper is too wide on the inside and rubs against the motor hub. I suspect other double-sided actuated brakes might have similar problems, so this may limit brake choices. Still using V-brakes for now.
