Popular Post Boostnsvt Posted March 4, 2022 Popular Post Share Posted March 4, 2022 The pictures below were taken when the wheel was new out of the box. The scariest was the battery packs. All of them weren’t sealed, so I sealed them up good. Another issue was that a solder bead on one of the connectors wasn’t done very well and it was completely exposed, which was basically like an open wire with no insulation. Another issue was that the tiny foam adhesive covering the perimeter of the side battery trays was displaced. After looking at it I found that the entire thing wasn’t providing much of a seal at all when properly aligned and closed. To fix this I lined the entire perimeter of both sides with silicone. I also changed every screw to hex screws, instead of the Phillips screws it came with. With the silicone and new screws the outside panels fit snug and feels very secure/solid. I think this made a big difference, because when removing the panel it’s like opening a Tupperware with a bit of suction. The last issue was the mounting plastic on the pedal hangers. I remember the first time I unscrewed the bolts, I could hear the plastic cracking or fracturing as I unscrewed the bolts. Scary! For structural changes I used epoxy inside along the front and rear of the wheel. There was a space along the sides (by the fan) and I just filled it up. Additionally, on the opposite side of the interior groves along the outer edge where the mudguard slides up there are groves that I filled completely with gorilla glue, then topped it with plastic JB weld. This will prevent any articulation from crashes and in-turn ensure gaps aren’t created along the interior silicone protection. Finally I used plastic JB weld to reinforce the mounting holes as well as the whole area around the pedal hangers. Every hole in the interior of the wheel was also filled/closed. This will improve water and dirt protection because each section of the wheel is almost completely isolated now that they’re sealed. For upgrades I added a ton of Lucas grease to the bearings and an additional bearing seal with EUCyou pedal hangers (both provided by eucyou) for a 10mm raise in height. Its not much but it does makes it feel a bit more nimble and the pedals fit like a glove with 0 play (very high quality machining). I also threw in a little neodymium rare Earth magnet to hold the petals. It’s strong enough to keep it secure without another magnet on the pedal. This little mod is very convenient and easy to do. For electrical safety I replaced a couple of the battery connectors with some EC5 connectors (I like these the most) and practically drenched most connectors and control board connections with liquid electrical tape. With the EC5 connectors and all the additional protective material it should reduce the potential of electrical shorts. I added a waterproof screen around the whole motherboard unit with some glue so I can rip it off easily. I found it on Amazon and it gives me some piece of mind (https://www.amazon.com/dp/B00230CRYW/ref=cm_sw_r_cp_api_glt_i_H2ATPSR45RXB0FQKAJAM?_encoding=UTF8&psc=1). It can hold water like a cup and it is so thin that I couldn’t notice a difference in the air conditioning on my face in the car. Really cool piece of material. I added two additional heat sinks. One in the front by relocating the Bluetooth controller and one in the hole to the wheel. I threw a small, flat 10v fan on top of the heat sink. This should fix any overheating as the heat dissipation was more than doubled. I don’t know if it helped, but it was a quick fix…when I removed the heat sink it was bear underneath. I added silicone-based heat sink compound for a 100% surface to surface connection. I purchased a tubeless tire but can’t find the right valve, so it’s waiting to be installed. I just got a cheap car valve and I couldn’t get it through the rim, so I might need to use a scooter or bicycle valve. I might add another 400-500wh lipo pack and reinforce the trolley handle in the future. Besides the heat sinks and electrical silicon, I sourced everything from my local hobby shop. I enjoyed tinkering with the wheel, because I like to upgrade my car and the wheel is going to be filling its role more often. It’s a blast to ride! 5 Quote Link to comment Share on other sites More sharing options...
thendless Posted March 4, 2022 Share Posted March 4, 2022 How much did the hangers cost? Quote Link to comment Share on other sites More sharing options...
Boostnsvt Posted March 4, 2022 Author Share Posted March 4, 2022 I got the seal and hangers for 230 euro, so I think the hangers alone were 200 euro. I’ll be buying from him again. Their products are above my standards. https://instagram.com/eucyou?utm_medium=copy_link Quote Link to comment Share on other sites More sharing options...
Boostnsvt Posted March 9, 2022 Author Share Posted March 9, 2022 Just a little update on temps. In 15-20 c atmospheric temperature, wheel temp was 45-48.4 c. 48 was the highest ive seen and it was on a trail ride. Quote Link to comment Share on other sites More sharing options...
alcatraz Posted March 10, 2022 Share Posted March 10, 2022 Curious. Do all EX.N's have the newer smaller bearings? Would you guys say that the HS model has got more torque than the RS19 HS? Is it closer to the RS19 HS or HT when it comes to torque? Quote Link to comment Share on other sites More sharing options...

All EXN has smaller bearings the torque of speed motors seems the same to me , RS and EXN HS i meanthe torque of of an HT is another level 1 Quote Link to comment Share on other sites More sharing options...

HS are closer to other HS no matter the wheels. HS never feels close to HT. in fact the exn feels like it has less torque than the RS HS to me. The light weight of the wheel (and a minor point: the better balance) makes the RS feel more playful and zippy. The exn needs considerably more force to wake it up. 1 1 Quote Link to comment Share on other sites More sharing options...
Ava74 Posted March 19, 2022 Share Posted March 19, 2022 Hi. I've bought the EXN HS model. Which is the better firmware to update. I seen two different updates. The C30 and C30 accelerated Stability. What's the difference? Quote Link to comment Share on other sites More sharing options...
Boostnsvt Posted March 27, 2022 Author Share Posted March 27, 2022 Little update…. the heat sink installed on the back plate of the control board was fairly clean. I was expecting it to be completely full of dirt or sand because I rode through quite a bit of mud. I was able to find a valve for the tubeless tire. I found it on a scooter website by measuring the diameter of the hole in the rim for the valve, which was about 8.5mm. The valves are sold based on a diameter range like 8.9mm-10mm. The tire is, for lack of a better word, amazing. It completely fixed all wobbles. I can’t believe how stable my EXN is now. Another big change is that I’m riding 5mph faster than normal. The smoothness combined with the stability makes the wheel faster or improved my confidence to ride faster, to a point where I had to remove the 2nd beep option (turns on at 30mph). If there anything you do to your euc I recommend you upgrade your tire! 1 Quote Link to comment Share on other sites More sharing options...
Boostnsvt Posted March 27, 2022 Author Share Posted March 27, 2022 (edited) Mitas 80/80-14. I probably could of fit a 80/90. I wanted to add that I used “STANS NO TUBES” tire sealant before install and it made the install very easy.

Goonman Posted April 10, 2022 Share Posted April 10, 2022 I'm going through my EXN HT now. I just got it. Some good ideas here thanks. I'm filing down a little bit of the shell to allow the wire to run in straight line over above the control board. Adding grease to the bearings as they were nearly dry. Looking at additional heat sinking I'm waiting on some top notch thermal paste. But I was surprised that the control board is attached with 6 little self tapers. So I'm going to drill through the original heat sink through the shell and bolt it down. I was concerned about how loose the shell was 'torqued' to the hangers but maybe to save crushing the plastic. I also use a non corrosive silicone to secure the capacitors I have seen them snap off. They are subject to vibrations and the legs fatigue. Also the battery pack BMS looks a little bit exposed there are some chips poking through the shrink wrap. They built up around them with foam but I will do something extra. There are so many opportunities for improvements from gotway. I heard they hadn't improved much since I bought my monster v3. But surely it's been a few years and the power levels have increased by a fair margin but seeing it for myself.....😞. It and HT came with a CST El cheapo tyre like the monster. So I ordered a shinko. See how it goes maybe get a Michelin later. I was tossing up between EXN and Hero. And honestly I think now I should have gotten the Hero. I valued range more than suspension though.

Boostnsvt Posted April 14, 2022 Author Share Posted April 14, 2022 (edited) I took the control board off and think the 6 self tappers are enough because it’s so light…like feather light. Overall it’s kind of disappointing to see all of these minor issues after spending $2500. It also made me second-guess my purchase, however after I completed addressing these issues, not only was I even happier that I decided to buy the EXN, I believe that besides the weight distribution and front light brightness, it’s a perfect EUC. It has excellent range, excellent weight, excellent speed, excellent maneuverability, excellent weather/water protection, a pedal high clearance and outstanding durability. Oh and I would recommend a street tire, unless you regularly travel up 20% or more inclines that have gravel or sand. I can make it up 15-20% inclines on sand, with the street tire on the speed version. Edited April 14, 2022 by Boostnsvt Quote Link to comment Share on other sites More sharing options...

Nice work on your EXN! I was wondering if you had a link or name for the tubeless valve you got? I'm trying to do the same with mine.

thendless Posted June 14, 2022 Share Posted June 14, 2022 What heat sink did you use for the wheel well and mobo? Quote Link to comment Share on other sites More sharing options...
Boostnsvt Posted June 29, 2022 Author Share Posted June 29, 2022 The wheel well was 100x41x8mm and the inside one was 100x40x30mm. On summer days from 94-98 Fahrenheit (34-36c) the highest temp I ever saw it go to, was 54 Celsius, but it usually hangs around 52. 1 1 Quote Link to comment Share on other sites More sharing options...
europunk Posted March 5, 2023 Share Posted March 5, 2023 Boost I just received my ExN HT took her apart and greases the bearings. Was going to do the breathable waterproof mesh over the board. How did it work? Also have you done the freestyler firmware or just the gotway? How have all your mods worked out? Wish you had done more or less? Anything helps Quote Link to comment Share on other sites More sharing options...
Dashhh1 Posted October 2, 2023 Share Posted October 2, 2023 Wow thanks for such and informative post! Would you recommend drilling some holes and putting in filtered air vents to increase cooling?
