Be careful with that rack. The failure point is where the tubing and solid part of the rear support are joined. I had two fail after several thousand miles with not much weight. Check my mod that has been working great:Decided to make the frame bag support so i can hide my electrics in a bag like before. In this case, since i'm either using a 9FET 4011 or the phaserunner, and either will bolt to the frame bag support for additional controller cooling
Example of this frame bag support from Super Hiryuu.. all made from home depot parts with a drill and dremel..

After putting the 52v 19.2ah battery in the frame bag, i noticed that there's a sizeable amount of room left. Enough room for one of these in series to get ~66v.

Nice top speed, this would be adequate for 35mph roads that don't have bike lanes. Using flux weakening to achieve this speed would put too much load 52v on the battery.. this would relieve it.

At 30mph, i draw 11.5A thanks to this higher voltage.. that's a 0.6C rate, which is really nice on the battery.. i also get 50 miles of range

Ok, since i'm filling the triangle with batteries.. what to do about water, tools, inner tubes, and, food storage for the long rides this thing is capable of?
I found this rack on ebay.. every part of it is adjustable.. it should allow me to sit the rack really low and forward, taking advantage of the 24" wheel's lower height,, it also has plenty of bolt holes, so i could bolt on a pannier support and have even more storage.
Plan to use a large plastic ammo can bolted to the rack... enough space for 5 1 liter bottles of water.
I’m using the same rack without any problems . I took mine apart and re-assembled it differently to how it is in the picture . I flipped the rear supports from one side to the other and upside down , that way the larger tube is at the bottom and everything isn’t pushing on the telescopic part .Decided to make the frame bag support so i can hide my electrics in a bag like before.

The bolts that come with the rack are made of cheese , I’ve replaced them all with something decent .
Actually, if it's low enough, there will be more overlap/insertion of the solid arm and may not be as prone to breaking. I'd just keep a good eye on it. Both times it broke while out riding. Luckily I usually carry a roll of electrical tape in my bag, so I was able to wrap half the roll around the parts to make it home.Zambam: I just ordered it yesterday.
E-HP: thanks for your advice; the design doesn't look particularly strong, but it does look amenable to being bolstered. I have some thoughts in mind because i want this rack to sit very low.
If you want the best rack out there , Aeroe is what bike packers use . They're extremely strong and solid (35lbs capacity) and extremely pricey for what you get .Smart! think i'll do the same, in addition to adding some more support.
Shouldn't be too hard to find. Most of mine are all in that range. Still might not be able to cover the whole motor because to avoid heel strike you may have to mount the pannier further rearward which would leave the forward part of the motor "uncovered." Depends on your shoe size and preferred foot placement on the pedals.I need about 17 inches of pannier to completely hide the motor, or 15 inches to hide enough of it. Looking for some panniers now.
Sorry to hear more problems. What's too hot to ride? Isn't Utah dry heat? More throttle, less legs, drink water. Would that help?
After several maladventures attempting rim straightening/spoke tightening during the earliest phases of my bike-riding career (preteen and early teen years), I too had a long-standing phobia against working with the spokes.I don't have a bike shop in the area that's willing to work on an ebike motor to retension the spokes. I've never done that before and would like it done by a professional.
