Hard to tell what it is right now. Someone adjusted the levels on the previous pic and it looks like this attached pic. Looking at it, it might be some kind of a cross between the Radmini & the Radwagon -- a mini cargo bike.

The 35A controller will be the limiting factor. It won't draw more than 35A from the battery. Basically buying the 52v battery with the 40a bms over the 30a version buys some margin of safety as I'm not sure how the 30a version will handle 35a of power draw.

There's a new bit of info on the page, the price: It's $1299. Interesting. Edit: forgot to add a quote from ebikeschool.com reviewer on reddit: "I can confirm that it's all good news. I can't say or confirm anything Rad hasn't yet, but the bike is a winner, rest assured. I'll have the first...

Different things. The 52v x 17.5aH (very important: "amp hours") is the capacity of the battery. Whereas the 40a is the max it can output at a given time. So the 52v x 17.5aH equals 910 Watt-hours of capacity. Think of it like this, the 52v x 17.5aH as the size of a gas tank, whereas the 40a is...

That pic makes it look like another variation on the Radwagon. Hope that's not what it is.

Looks like Rad is announcing a new bike on 8/22/19. From the teaser video https://www.radpowerbikes.com/pages/radrunner it looks like a Juiced Scrambler type bike. Interesting, I've been checking those out recently as they look like fun little bikes. Though I heard that the Juiced one is huge...

The only setting I remember changing was P2 =5. It was something else before that.

2 people running 52v + 750w motor already reported heat issues. I smelled burning plastic, spmckinnon's motor was hot to the touch. Mine is now already turned down, I am not going the risk melting nylon and turn the power back up just to get data.

Higher speed equals higher RPM inside the motor, more frictions & heat in the bearings & nylon gears. There is at least a 7 mph difference from my own observation between a stock motor with the Bolton kit vs 750w motor + 52V with the Bolton kit.

Here the difference is some of us are running hotter motors (bigger magnet 750w) plus 52 volt batteries with our Bolton kits.

Yeah, 1600W is a lot of power, thus a lot of heat generated. I've read some people caution about melting the nylon gears (remember those when replacing the motor?). That's why I was a little worried about smelling something. At least we have a spare set of nylon gears from the old motor.

Haven't had any issues yet. I might have been a little paranoid a couple of weeks ago and thought I smelled plastic after going up several blocks of steep hills. I saw something like 1600w while going up. After that I dialed down C5 setting to 8. I think that might limit it to around 1400w. I...

No, you won't get that kind of customization with this kit. The setting for assist level is shown in that video as C-14. There are only three settings for C-14: 1, 2 or 3. The default is 2.

Looks like you might be able to do this: drill a hole around where the middle arrow is, slide the bottom screw to the bottom arrow area, then the top screw might fit the top arrow area. But take exact measurements first before drilling, and you might have to file the top & bottom arrow areas a bit.

I uploaded that mount to thingiverse.

I had no trouble with all three screws by using the top 3 slots, as you can see in the picture here. Maybe Rad changed the mounting spacing from my 2016 to your year. Yeah, I would not trust just 2 screws either. But since you say you were able to line up the bottom two, maybe just drill new...

For those considering changing to hydraulic brakes, this sensor (though they seem to have raised the price, I got it for ~$14 for a pair) has the correct connector. The wire it came with is a touch longer than the stock wire. And for installing on the Shimano M355, it's best to fabricate some...

The last Black friday price ($2999, from the regular price of $3499 at the time) on the Hyperfat 1100 was really tempting. But saw some posts on reddit about it having issues where it would hesitate on certain speeds. Plus they were talking about how that same issue was never fixed from the...

I got number 7 by not making any request. Supposedly that's the default for shipping to USA if you don't make request. And # 1 looks like an anti spark xt90, that's supposed to be the preferred for high power stuff. One benefit of getting #7 was that it fit's the original rubber grommet on the...

You are missing something really big in this thread, the stock motor on any Radrover (likely the Mini too) is under spec, US or Canadian. 2 people have posted pictures comparing the stock "750w" motor with its smaller magnets than a real 750w we bought from aliexpress. See this youtube video...
