This measurement includes the tyre
UNT Units of measurement (0,1,2,3) 0=Km/Celsius
1=MPH/Celcius
2=Km/Fahrenheit
3=Miles/Fahrenheit
P1 Motor Gear Ratio 100 – geared motor

46 – direct-drive motor

P2 Wheel speed sensor (0-6) 5 The number of magnet pulses generated per revolution of the wheel. For most 750w motors, the setting is 5. For most 350w motors, use 6. If speed reading wrong, try different settings.
P3 Relationship between pedal assist
and power (0-1)
1 0= Amount of throttle limited by whatever level of assist you are in at any given time.
1= full throttle whenever you want it.
P4 Pre-condition for throttle use (0-1) 1 0=Throttle works whenever you use it.
1=Throttle works only if you are pedaling.
P5 Power monitoring mode. (0-40) 15 Adjust the way in which the display calculates how much range you have left.
0=default mode: uses real-time battery voltage to determine the remaining range.
1-40 = smart mode variable settings. For example:
11=Smart mode for 24v battery.
15=Smart mode for 36v and 48v batteries.
Increasing the setting number will make the battery meter think you’re running out of power faster. Adjust setting to achieve an accurate battery meter readout.
C1 Pedal-assist sensitivity setting (0-7) 3 Allows for different sensitivities with certain Kunteng brand power assist sensors.
3= 12 magnet sensor
C2 Motor phases. 0 0=Bafang and other ordinary motors.
1-7= motors using a special motor phase.
C3 The default level of pedal-assist when
the bike is switched on (1-5 & 8)
8 1-5=set default pedal-assist number.
8=pedal assist will be whatever it was when the bike was shut off.
C4 Throttle control (0-5) 1 0=Throttle always works and has full power (up to max set by C5).
1=Throttle works up to 6 km/h without pedaling, full power if you pedal.
Other settings=variety of odd effects
Note: this setting relates to the P4 setting.
C5 Maximum controller output (0-10) 5 0= slow start 3-phase to max current (current increases as you pedal).
1= slow start 2-phase to max current (current increases as you pedal).
2= Gradually works up to max current.
3= max ÷ 2 (50% of max current)
4= max ÷ 1.5 (67% of max current)
5= max ÷ 1.33 (75% of max current)
6= max ÷ 1.25 (80% of max current)
7= max ÷ 1.2 (83% of max current)
8= max ÷ 1.15 (87% of max current)
9=max ÷ 1.1 (91% of max current)
10= max current (100%)
Note: tuning this setting in combination with C14 is the best way to tune power/range. It applies to all pedal assist settings. Max current is calculated by multiplying the battery voltage by the controller amp rating (48v x 35 amps = 1,680 watts)
C6 Backlight adjustment (1-5) 3 1 is least bright, 5 is most bright.
C7 Cruise function (0-1) 0 If this feature is activated, holding the up arrow button when riding will set the cruise control at your current speed. Cruise control is canceled by pressing a button, using brakes or throttle.
0= Off
1= 0n
C8 Motor temperature monitoring (0-1) 0 Only works if your motor has a temperature sensor (RAD motors do not).
0= Off
1= On
C9 Password (0-1) 0 0= Off
1= On
Warning: unless you are prepared to set (and remember) or already have set (and remember) the password for your screen, DO NOT turn this feature on. You will be permanently locked out of your screen
C10 Reset to default (Y/N) N Y: reset the screen to default settings.
N: leave custom settings as they are.
C11 Communication protocol setting (0-2) 0 Used for setting transfer to other displays. You probably never need to change this.
0= off.
C12 Minimum voltage cut-off point 4 This adjusts the point at which the battery will be automatically shut off to protect it from being drained too far down. 4 is the default setting, with values above and below that incrementally raising or lowering the limit by 0.5 volts.
For a 48v battery, this should be set at 40v, which is the 4 setting.
Warning: setting this lower than 4 could result
in permanent battery damage.
C13 Regenerative braking (0-5) 0 Only applies if you have a direct drive hub
0= no regenerative braking.
1-5= increasingly uses braking to recharge the battery (5 is most braking resistance/charging)
C14 Power assist tuning (1-3) 2 1= less power assist
2= regular power assist
3= more power assist
Note: This only affects pedal assist settings 1- 4. Pedal-assist 5 is always full power.
Note: Tuning this setting in combination with C5 is the best way to tune power/range.

    I love my RAD. But the only thing left on it that is original now is the 500watt motor. Everything else that has been added or needed replaced I've bought replacements from Big Game Bikes, a third of the world, an ocean and a continent away. And I have always gotten my order within a couple days. That should tell you something. This 35amp controller is fantastic. And it took less than an hour for an amateur (such as myself) to install. I will say that the cable is JUST long enough. I actually re-routed the cable from the Battery tray to NOT go through the frame. That made many things easier actually. I mounted the controller in the same place with Zip Ties and also velcro straps. It's very secure. The screen is color which is a nice change. It's not as bright as I was thinking it would be but it's also not an issue that it isn't. The settings are easy to adjust (Make sure yours is set properly before riding your bike). My original controller had failed and stopped providing 5vdc to the display. I suspect the display is actually still good but I haven't verified that yet. I'll buy a bag for the controller soon because it is NOT weather/rain proof. But this is a fantastic upgrade or fix for a broken controller/display. I highly recommend it, if just for the optional increased torque alone. And I can't say enough about BGB and their customer service. Even though I'm a 3rd of the world away, BGB will likely always be my first choice. Thanks Gareth.

    I have a Rad Mini 4 which has the EU limitations. Whilst it did make a difference with the hills it was not quite what I expected. After fitting the controller and display up grade all I can say is WOW!, it allows me to cycle up the hills without dropping gear and fly past the conventional cyclists.

    If you have the throttle set to full power then the acceleration is amazing, it can even lift the front wheel, good job I am a heavy lump.

    Next upgrades will be a battery and motor.

    If you are considering this all I can say is go for it, you won't be disappointed.

    Things to consider: The controller is larger than the original unit so you cant use the original mounting brackets, I mounted mine in the same location using cable ties. You will also need to cable tie the cables back to the bike after having to cut the existing cable ties to remove the original controller. Fitting took approximately 30 minutes as all the cables were plug and play. Ensure you fully seat the cable connections or you may have a motor position sensor error.

    I just finished the install on my RadMini, it was very easy and straight forward.
    Then the test ride, wow, this is the way the bike should of come in the first place. Right away you can feel the extra power, just rips up hills now.
    I think this is the best bang for the buck you can get, you won't be disappointed

    This controller will fulfill all your dreams..

    A real must have for any one who wants to unleash the power of the radwagon ! It turns a slug into a race horse ! Even with my two kids on the bike I can climb stepped hills in no time, effortless and cruising at 40 kph... incredible ! I strongly recomand the hydraulic brake upgrade to stop the beast ! Half an our of work to put this bolton, ready to plug contoller my wagon. The only trick is to find a solution to fix it on the frame : here is my (simple) solution... I ll do better next time ;-)

    I would highly recommend the 35amp controller upgrade (previously used the eggrider) 67% power setting was perfect for me as you still get the same top speed and accelleration was not so fierce (as any higher it kept wanting to pop a wheely). It also has much more torque, it used to struggle with my 7 year old on the back against a headwind but no more. You can get it to fit using the stock mount and bolts if you persevere and i would recommend using scotch 1601 3M sealer spray to waterproof it

    I installed 35A controller in RadWagon version 3. All parameters set as suggested. I set the speed to the value allowed here. This is strictly adhered to. A big advantage is the much better acceleration to this value. The strength on mountain routes is also better. I can only recommend this part. Please calculate the customs and VAT with about 62 euros. It's still worth it!

    OMFG, 35A controller upgrade.
    I know many, many people reviewed the 35A controller upgrade already, but I had to write my own review. I just tested my upgrade with the new controller from BGB and WOW, thank you Gareth S, I knew it would pull harder but I never thought by that much. I'm at the top end of heavy riders and with the stock controller on my Rad Mini 4 2021 I would only get to the top speed of 33km/h (20M/h) on a slight downhill and in ~20sec, now I get to 33km/h (20M/h) in around ~5sec on flat ground or even on a slight uphill. Also, since I have not yet change the motor for a true 750W I configured the power to only 80% not to burn out the original motor.
    I can't wait to do the motor upgrade as well, this thing will be a cross between an Ebike and dirt bike. In my opinion, this is a must-do upgrade, it transforms the Rad Mini in what it should have been from day 1.

    Imported to Spain, feels like it took forever due to Spanish customs. Easily Installed on my Radrunner plus. What a difference this is to the bike. Well worth the wait. I contacted Gareth re the waiting time. He telephoned me in Spain to let me know this is normal. Thank you Gareth, I fully recommend your company. This is how this bike should have been made, and only set to 75% of the power👍

    Thinking about upgrading to the more powerful controller? Do it! Installation is easy, plug and play. The only tricky bit is attaching the controller to the bike as the stock Rad parts don't fit. But, this is remedied by either purchasing some longer (same diameter) bolts and using the stock fittings or (as I did, temporarily) use heavy-duty stick-on Velcro and zip ties. I've just been out in the woods on very bumpy terrain and it hasn't budged a millimeter. You could use a bag or Amazon does sell Controller boxes quite cheap, so there are plenty of options so don't be put off.

    The power difference is night and day, on full power this thing gives 1200-1500+ watts, I think I may have seen 1600+ at some point, it's ridiculous. Uphill riding is so much better. Top speed isn't affected but I'm not personally not interested in that, 20-24mph is fast enough for me, I purchased it for the extra torque and it delivers. Besides it gets to 20mph in no time at all and crossing intersections is actually safer because you do it so quick, actually so quick that my suspension seat post dips down when I accelerate!

    Obviously, your range is massively affected if you are riding everywhere full power but it also would on the stock bike riding at full power. To give an example, I am 20 stone and I have just ridden around 12 miles going almost full power everywhere and there is 1 bar remaining on the battery. I did a few very steep climbs into some local woods, in fact, it was so steep I lost one bar going only 3.9 miles but a lot of it was at full power. I wasn't concerned with the range I just wanted the full torque all the time and did a lot of accelerating up to 20mph then braking so was very impressed with the range considering I was using the full power lots of the time. Reading the instructions it says once all bars are gone you have 15% battery left, considering it had only just gone to 1 bar there must have been at least 25% of the battery remaining.

    One thing I like is the PAS, PAS1 gives around 185watts, PAS2 300watts, PAS3 450-500watts, PAS4 750-800watts, and PAS5 is the full 1200-1500+watts. This can be adjusted in the menu but I like this because PAS1 is great for just riding around and not using a lot of battery but PAS4 when climbing a hill is the equivalent of the full power of the stock Rad but just a tad more powerful topping out at 800watts. But, you've got that extra power if you start flagging by either going to PAS5 or just turning the throttle. It's basically like riding the stock bike on full power up a hill but you have an overdrive button that gives you that extra boost, something I think the stock bike was really missing going up a hill.

    One other great feature is the USB port on the new display. My old one did have it but I tried running light off it and it was hit and miss and I gave up. On this new display, I can plug an extra light into it (a super bright nighttime 1200 lumens light) and it will run off the bike's battery!

    Pros: Good price, the best bang for your buck in terms of power upgrade, easy to install, great new looking display, a USB port that works well, brilliant torque!

    Cons: It Will eat your battery up if not careful (but to be expected), a fitment kit for the new controller would be nice along with it to make installation easy.

    Overall I would say this controller upgrade is worth every penny, it's like a new bike and so much fun, I'm so glad I bought it and Gareth from Big Game Bikes is so helpful. If you are stuck and email him he'll ring you before you've clicked send to help you out! And also take your calls and talk you through things, brilliant customer service.

    p.s. I'd advise upgrading to the hydraulic brakes, I did and I'm so glad!

    I am new to the e bike scene and a bit apprehensive ones it comes to working on the bike but I learned that there is lots of help and advice out there with social media groups and than there is BGB with Gareth always giving helpful advice when needed! I first bought the EggRider before it came plug and play. Found the setting up a bit to much for me and sold it again! Got the 34 amp controller and new display from BGB and never looked back! A lot more torque and speed but for me with my bad knees the all throttle control was what I am after. I am very pleased and excited with this upgrade!
