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!

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.

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

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 😉

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??
