First let me get this out of the way: Good to hear your mid-drive/hub is been running for 4 years... I've only had eBikes since October last year so I can't comment on what will happen 4 years from now. Regardless of what happens to me in 4 years, you also had a terrible first experience as well, more like a couple with various GNG kits; so stop preaching like you know better and making fun of my bad luck with my previous GNG... we all have to learn at some point and this is my learning, but be assured I'll get to where I need to be just like you did.
Yup, just make the torque gradual start up... but the torque, wether gradual or insta-snap still there; and massive amounts of torque are still going through the chain of a single geared mid-drive. (a hub motor you don't have to deal with chains, etc, but even hub motors could benefit from using 2 or 3 internal gear reduction). You're still limited to whatever max speed the motor coil windings are (no chance to overdrive in a downhill for example)... plus you need a motor with enough torque to make up for the lack of gear reduction... yes its simpler, of course it is, but simpler sometimes isn't as versatile as more complex. A plane is very simple aerodynamically speaking compared to a complex helicopter, but helicopter can do a lot more tasks than a plane simply cant. Sure, both fly (and plane files faster), but the versatility of the helicopter is unmatched for short range aerial operations. If I need a bike that rides 100 miles, sorry, I will drive any of cars at that point.
I do know about higher voltage, known this since I put my first RC helicopter together back in 2006... Power = I x V, and you can achieve it either way... unfortunately, I don't want to run more than 48 volt on my bike because if I was to touch any connector soaked in salt water I don't get electrocuted... 48V already gave me a funny tingle when I touched the connector soaked in salt water to disconnect... please, lets put 100 volts so you can get electrocuted.
fanatic?, I am simply excited that something finally worked... and I still think that 380 bucks gets you a fairly good kit. However, you don't seem to be agreeing with that and I don't see what is your problem with that. You seem to be bashing the kit with subtle speculative comments like "oh, plates seem too thin" "probably flexes too much" "it can't possibly last very long" "controller is probably crap" etc... all when you don't have 1st hand experience with this kit, so perhaps you should stop feeling like an authority in this kit, and if you want to bash it, get one and install it... but I think you'll be pleasantly surprised. In the meantime, I do have this kit running and running very well; and while it has its shortcomings and needs a bit of preparation work, once its in, its a fairly robust kit. My only issues have been with water/salt getting in the damn connectors... an issue for which I might just solder all cables and be done with it... (I don't plan on taking this kit ever apart if it works well...)

and there are solution for hard starting middirves which I believe I posted several pages ago?
oh man, who said you can only do this electric bike thing with high amp high Kv setup? raise the voltage enough and use a low Kv motor. and you wont need to push insane amount of amps to your motor. And if you can't figure out how to make things work on a high amp ebike build, then I think you should do some more reading on the older threads here.
First you deny the fact that the mounting hardware is under built at stock configuration, 2nd that it doesent flex....cool you found the solution to reduce the flex, but it still flexes according to your earlier post.... now 3rd, you dont believe the drive is powerfull enough to snap your chain the way you do gear shift.... then recently snapped a chain......4th wanted a less complex ebike setup so they don't break but dont want to hear anything about going single speed mid drive with proper reduction, which other builders are successful doing https://endless-sphere.com/forums/viewtopic.php?f=28&t=47054also don't like hub motors, so you like cyclone mid drives since it's less complex and too few places that it can fail but in reality the kit is very complex and has alot of potential points of failure? we havent started with wear and tear yet on high powered mid drives...... Man why are you even on this forum if you cant take other peoples criticism about your build? Sounds like a fanatic of a certain brand. As I recall, you are the same way with your GNG gen2 till you found out yourself it's falling apart left and right. I suggest trying out/building a few other style of ebike so that you have a better understanding how other setup works.
