I did not ask for proof that the two motors differ with respect to torque, or even whether they do. If you read my first post carefully, I asked (in effect) why both motors are spec'd for torque at 80nm when one (the upgraded motor) reportedly has more torque than the other? If true, then one of...

Thanks. I am aware of the disparity in the advertised power ratings throughout the ebkike industry, the reasons why, and in particular how RPB has inflated its number (strictly speaking). But this does not answer my question about the relative comparison of torque between the stock RPB motors...

Thanks. This thought had definitely occurred to me. But I don't think ebike manufacturers have the same kind of wiggle room to fudge the torque spec in the same way as the power spec (e.g., by rounding up instead of down). Though I may be mistaken about this.

Thanks. Didn't really answer either of my questions fully (beyond what I already know). I know, for example, that the upgraded motor connector work "plug-and-play" with the stock motor controller in the sense of mating with the stock connector and delivering power to the motor. My question, more...

Hi folks, couple of quick questions (for those who might know) about the Bolton/EBW Bafang "true" 750w motor upgrade. (1) I have read/heard from multiple online sources that the upgraded 750w motor provides additional torque over the stock Rad motors, but not increased speed (without a motor...

Looks great! You appear to have the same Bikeroo seat as I have on my RadRunner. I have a spare battery for the Runner, and have done rides up to 65 miles (with some power to spare). However, I learned that my batteries will outlast my rear end -- I can't ride/sit on that saddle for more than...

Thanks, but if you just ordered the bike then it will be a 2020 model with a motor controller that I cannot use.

I don't quite understand what you are saying? You now have a RadRunner, and are considering upgrading your motor controller and display??? If this is correct, and your RadRunner is new (2020), then I cannot use that controller. To repeat, I am looking for a motor controller from a 2019 model...

I agree, in general, about Amazon. In this case, however, China via eBay/AliExpress/Wish is the only source (that I can find) for these particular items. Sounds like good progress on your end -- look forward to a few photos!

Well, my 3-speed sprocket experiment failed. While the new sprocket fits the threads of the freewheel hub on the stock RR motor, it will not screw on deep enough to clear the dropouts -- off by about 3/8" and I see no easy way to modify the new sprocket to make it fit. Alas, $16 down the drain 😂...

Cool, thanks for the idea! On a completely separate topic, I thought I'd share another idea for anyone who might be interested -- a lockable storage compartment that I fabricated from 1/16" aluminum stock (see attached photos). I made one of these for both of my RadRunners, and love it -- great...

Right; it's the added rise of the fork that causes a slight problem -- this raises the entire bike, including the kickstand, but not by much. The consequence (based on the fork I used) is that kickstand still worked -- the bike would still stand up on its own on a flat paved surface -- but was...

I got my Thudbuster ST (3G) new from Universal Cycles for $99 (+$12.95 tax and shipping) back in May. Though this may be a tough deal to find nowadays.

I don't think so because the male threads for the freewheel hub are integrated into the motor housing itself. If you put loose spacers over these threads, you could not attach the freewheel. This is why on the RR1 both the spacer and threaded freewheel hub are integrated in the motor housing as...

I'll say more later because I am travelling at the moment. But just briefly, the 1/16" shim I mentioned was to solve the fork problem, not the derailleur problem. A long cage derailleur might force switching to a side kickstand.

Also, my new 3-speed sprocket has arrived and I plan to tinker with it over the next couple of days. Since I do not yet have an upgraded motor, I am hoping (betting) that this sprocket will fit the RR1 even with the offset spacer. I believe it will because the new 3-speed sprocket is...

Just to be clear, and to repeat, the RR1 appears to have a custom motor case (or housing) on the side of the rear sprocket -- it contains an offset spacer that I believe is absent on all other RPB bikes that come stock with a 7-speed rear sprocket, including the RR+. This spacer (I believe) is...

I am keen to hear how this turns out, and exactly which components you used. As mentioned, I have opted for a 3-gear sprocket for the time being (mainly because I am not yet prepared to drop close to $500 on a new motor, controller, and display -- my hope is that prices on these items might...

It might also be possible to use a pin spanner wrench such as this one: https://www.parktool.com/product/pin-spanner-green-spa-1

Near as I can tell, yes (everything you said here seems to me correct). However since I have not yet performed a motor swap, I cannot say with any great certainty/confidence (beyond what I can see from photos, what I have read in other forum posts, etc.). I actually own both a RadRunner 1 and a...
