    Radrunner/Radrunner plus Hill climb

    As you mention, weight matters (most), and less so a number of other environmental factors such as temp, wind, etc. that can affect the performance of your battery on a given day. My RR+ gets me (@210 lbs) up some pretty steep hills, yet requires pedaling effort -- don't count on steep hill...

    Radrunner/Radrunner plus Hill climb

    Yeah, the shiftable gears on the Plus help a lot! I outfitted my RR1 with a 3-speed rear freewheel sprocket/derailleur/shifter + Bolton motor controller upgrade, and with this combination my RR1 easily outclimbs my RR+ (I own one of each). But notice that in my experience the Bolton controller...

    Radrunner upgrade to TRUE 750w Bafang hub motor

    Correct. I also own a RR+ with the 7 speed freewheel, which I could only remove using the split freewheel removal tool from RPB (and even then it was a royal pain-in-the-$%#@ to remove because that tool does not fit snugly/securely inside the freewheel without slipping -- the diameter of the...

    Radrunner upgrade to TRUE 750w Bafang hub motor

    For what it's worth, I was able to remove my freewheel using a center punch and hammer. The stock Rad freewheel has notches on it (for a freewheel removal tool), which can be used as bearing points for the punch. Hold the punch on a notch at an angle, and make sure you are driving it...

    Just ordered a RadRunner 1 looking at seat option and user experiences.

    I agree with most others; the stock RR1 rider's saddle is junk. There are lots of alternatives out there, but I purchased a Bikeroo saddle (over a year ago) for ~$35. It's pretty comfortable, IMO, and is holding up well after the first year with lots of miles logged. Perhaps more importantly, I...

    RadRunner Suspension Fork Upgrade

    Btw, if you do go for an aftermarket fork just make sure the dropout width matches the stock fork (I think it's 135mm, w/quick release skewer hub), and that the neck tube is at least as long (cutting a longer tube to fit, if necessary, is a pretty easy job if you own a hacksaw, or know someone...

    RadRunner Suspension Fork Upgrade

    That's actually not a bad idea -- if you live in/near Portland there are bound to be several RR+ owners nearby. Place an ad in the classified section on this forum. The price for the RR+ fork, btw, is $150 + shipping (or anyhow that's what they charged me). Offer your "fork mule" maybe another...

    RadRunner Suspension Fork Upgrade

    I did. But I've also heard reports that RPB won't sell these forks to customers who don't own a RR+ (probably for liability reasons) -- I happen to own one of each. But if you can get them to sell you one, I can confirm that this fork fits the RR1 nearly perfectly -- took me ~30 minutes to swap...

    RadRunner 1 - remove speed limiter?

    I own a 2020 RR1 and can confirm that the pin cover hack does not work on these newer Rad bikes. I also own a 2020 RR+ with the LCD display, which is also speed-limited to 20mph (this limit can no longer be overridden by changing the display parameters). Near as I can tell, your only option for...

    RadRunner Suspension Fork Upgrade

    I put a RadRunner Plus suspension fork on my RadRunner 1. I imagine that this fork is very similar to other basic aftermarket spring forks. Just be advised that most of these forks only accommodate a rear-mounted front brake caliper, which is side-mounted on the stock RR1. But all you need to do...

    Radrunner (chilli with peppers)

    After putting just a couple hundred miles on my new RR+, I noticed that a tooth had broken off the lowest gear of my 7-speed sprocket. I reported this apparent defect to RPB (with corroborating photos), and they elected to send me a new sprocket under warranty along with one of those pre-split...

    Bafang 750w Motor Upgrade

    Interesting. One immediate concern is whether this motor is seamlessly swapable with the existing case of the stock RPB motor? -- i.e., without having to re-lace the rear wheel spokes. A second concern is the connection to the motor controller -- i.e., whether it is "plug-and-play" or requires a...

    Bafang 750w Motor Upgrade

    Thanks. This sounds closer to my initial guess-timation; that the physically larger "true" 750W motor has more windings, maybe uses heavier gauge copper, and can therefore probably handle higher currents for longer periods without overheating. What I did not fully understand is how this...

    Bafang 750w Motor Upgrade

    Also excellent; thanks very much for your input!!!

    Bafang 750w Motor Upgrade

    Excellent, thanks again. And I meant to say above with respect to battery capacity watt-hours, not amp-hours.

    Bafang 750w Motor Upgrade

    This is a potentially helpful clarification. However I have been under the impression that battery voltage (if that's what you are referring to) basically translates to greater range (in amp-hours) -- e.g., that a 52V battery will normally last longer than a 48V battery (at a fixed current and...

    Bafang 750w Motor Upgrade

    Just to be clear, my own personal concern/goal is not higher speed. What I want, primarily, is better hill climbing power. And I know that higher torque translates to better climbing power. The issue with my RadRunner is that above a certain gradient -- I don't know the exact figure (probably...

    Bafang 750w Motor Upgrade

    Thanks. Micah Toll of Electrek, who I trust to be knowledgeable on such matters, created an excellent video explaining in detail how and why the industry inconsistently rates motor power (in watts), and he specifically addresses (and justly questions) RPB's rating. This much I understand -- that...

    35Amp Controller on my 2020 RAD Mini install with pics

    Sorry for not being clearer; when I say that I have a spare battery this just means that I carry a second battery which I swap in when the first runs low, not that I have both batteries ganged together in parallel (though from what I read this is possible so long as you manage the balance...

    Bafang 750w Motor Upgrade

    Thanks Dave. I've watched all of Citizen's videos multiple times, yet which don't answer my specific questions (or near as I can tell).
