Pushing 130+phase amps at 60v through the modified 1000w G062 Bafang geared hub eventually broke the clutch 
I have now upgraded the clutch solid to take the power more reliably.  Regen braking will now be also functional. This will nicely spare my  Magura MT5E pads from premature wear (rear pads lasted ~500miles).

New here. I am from the USA currently traveling the EU with my RV. I am getting ready to purchase the RadRunner Plus. In the EU you can only get it in 250 watts. In a couple of month I will in Turkey. I would like to replace the motor with a more powerful motor like a 750 watts or better. What are my options and can i get it shipped to me with out spending a whole lot of money. Can i get one shipped in the EU? Thx

The differences between EU & US models are controller/display programming. All the hardware is the same, motor too.
So all you need is Eggrider or 35A controller kit. In Europe you can get them from Biggamebikes.

My custom controllers have sealed seams and grommet. Most importantly The pcb is conformal coated.

Stock motor will turn faster with higher voltage battery. Higher voltage means higher speed and this in turn means higher current which easily results in overheating problems.
Stock motor (G060.500.D ) comes in few different KV versions. At least older Rads came with several kv versions (7,8,9,10...)..
For example RR with stock motor and 62v here--> https://youtu.be/VDvENbyR5PA

My motor gained nothing with a voltage increase, so I guess some motors have it and some do not. That was the only reason I switched out my Rad motor, as it had more locked rotor torque than the Bolton motor. My original motor is out on loan so I can't check the model numbers, but I did run into a wall at 1757.96 RPM (before gear reduction). Sucked for me, but good for those that don't have that issue. Water under the bridge now, lol.

Gained no rpm (no load) with higher voltage? Did you use stock controller and display. The stock display of course has speed limiter hard coded.
Rpm/V should have linear fit R2=~0,99.

You can email Bolton Bikes (Now called Area 13 Bikes), and ask if the controller is compatible with Bafang motor model number RM G062.1000.D 06. I fit is compatible, the Bolton controller will need the motor connector replaced with an L10 connector on the left side of the bike, and you may need to adjust some of the controller settings like the number of speed sensor magnets. The motor will also need to be laced into the wheel because the motor casing is different, and the spokes attach to the casing.

Regarding motor noise, it is a little louder than the original motor, and the Bolton controller will make it louder because it does not use a smooth electrical waveform like the Rad controller. Some people may not notice any difference in noise, but I'm a sound engineer with sensitive ears.

For performance, the 1000 watt motor is awesome. This past weekend I had a group ride which turned out to be mostly gas powered moped and scooters, and they could not keep up with the Rad, especially climbing steep hills on the way to a scenic overlook.

Motor temperature sensor comes handy with this level of power. Even with vented motor the temperature rises quite fast
I'm now running the motor 130+ amps (phase) at 60+v.. The bike feels bit like small dirt bike when throttling as the front lightens 
Also proper torque arms are a must. I'm using one on each side.

The front becoming light is why I dialed the power down a bit. The climb to the lookout summit had steep grades and hairpin turns that were wet with pine needles. Not a good time for the front to slip out!

I'm just loving it at times 
Mostly cruising on pas 1 -2 though.

Cool! 

Start saving up a rear-tire replacement fund.   

Indeed! Wonder what the 0 to 20mph times are 

This is 0-20 test with old controller.

Now tested...wow. Crazy torque

I have a EU RadRhino Step Thru 1. I have upgraded to an Eggrider 2 and Shark Battery at 52V. Recently the bike won't turn on at all but after testing there is defo power coming out of the battery. I'm wondering what the maximum voltage the standard RAD controller for my model can take. I am aware that the Eggrider cannot exceed 60V but the battery does not exceed that when stressed.

Assistance would be gratefully received!

52v battery fully charged is 58.8v. Rad controller components can take maximum of 60v..  This means max voltage is not the problem.

Awesome, what controller is this? I've been flirting with the idea of upgrading my 35A controller lately. Wondering what other more powerful options are out there.

This unit is one of custom factory order for testing purposes. I have 48-60v battery compatible 40A controller kits on stock now. Motor connector is L10 for 1000w motor. Battery connector XT90 Male. Otherwise plug n play for Rad (new models with semi interested battery excl.).
Kit includes controller, main harness and high voltage version of LCD8H.
220€ + shipping.

Can't wait to get my new 60v 60A SW
"plug n play" controller kit tested on my Rad

Just a side note  Phaserunner is ~40-45A peak battery current and up to 96A phase current.
So @ 52v ~2700w peak.

Perhaps you are thinking of the lower capacity Baserunner? The Phaserunner software only permits settings in the allowable range, and the upper limit for peak battery current is 96.5 amps. They recommend 40 amps, but 96 is allowable. I have mine set to 60 amps, and have seen motor peaks of 2980 watts. However I may have overlooked something, and will double check.

No. Phaserunner is 96A phase current.
https://ebikes.ca/product-info/grin-products/phaserunner.html

I spoke to Grin Technologies, and the inventor of the Phaserunner himself has also looked at my configurations.

"The max battery amps for the Phaserunner is 96A"

The attached image is from their updated owners manual.

I know that theoretical figure but its nothing related to real life use (as you can see from suggested max battery DC setting and Phase current max).

You seem really stuck on this, but it's a peak figure and not a nominal or continuous rating. It's normal for such a device in a compact form factor. The bike is quicker than an Ariel Rider Grizzly, accelerates up 22% grades, climbs better than a Bafang BBS02 equipped mountain bike, and is faster than 90% of the commercial e-bikes sold in the US. All this with a controller that will fit in your pocket and doesn't scream "I've been modded!". Nope, it's not going to touch your bike, or a Sur Ron or Delfast, but it does an unexpectedly good job.

Anyway, thanks for all the interaction my friend, and perhaps I'll edit my original post to indicate those are peak and not continuous numbers.

Sorry. I just find this perfect real world discussion (and nothing more) relating to phase amps and battery amps 

The thing what I tried to say is that Grin and the Phaserunner manual suggest setting peak battery current to maximum of 40A. Its technically possible to set it up to 96A but that does not mean the controller will now output 96A battery current. Why is this? Because phase current peak max is also 96A!! So in theory if the controller will hold and just do thermal rollout after some seconds you could peak ~76A battery current or 3850w with fully charger 52v battery.
The pictures are for Grins motor simulator which I use alot. First is the comparison of recommended max settings with Phaserunner vs 40A (battery) 96A (phase) controller. They are a match.
Second is theoretical 96A (battery) 96A (phase) compared to the previous 40A 96A.

I get it, and it has been interesting. I'll take your simulations, and raise you real world usage
By the way, did you include 30 amps of field weakening?
I hit over 60 amps frequently, but with the bike getting up to speed in 4 seconds, there's not much need for sustained power except the last mile in traffic.
Just for fun, can you recommend another controller in the same form factor that does 60 amps? Grin is affected by the chip shortage and is substituting what they call the "Frankenrunner", which is significantly larger.

Yes for field weakening.
Phaserunner is absolutely one of the best in its class. Next step would be bigger Asibac

Btw. Tested today how winding temp rises when blasting 15 minutes on high power and speed. Temperature rise was from 60F (ambient) to 227F....casing temp ~100F.
Afterwards initial cooling was 12F per minute.
