  1. I bought an e and within 2 days It broke while riding, I was braking really hard and it cutout at like 2mph, i stepped off and it shuddered for 20 seconds. After that it shutoff and wouldn't turn on, and motor was rough. Left it outside overnight and then the next day took it apart. To my surprise everything looked fine. Once inside I learned: - wheel would boot up fine with motor unplugged and connected to bt. - motor spun freely by hand when unplugged from mobo -with everything off and motor unplugged, the motor wires green and blue were shorted on mobo when tested with multimeter So I replaced all the mosfets with slightly high spec'd ones, they're rated for 80v 100A instead of 75v 75A, so hopefully they will be less likely to pop. STM STP100N8F6 The originals were HEXFET ® Power MOSFET 75NF75 for reference. The wheel works great now!
  2. Hello All, Looking for some input from the masses here... I just got a Begode hero from Aliens Rides in the US and have absolutely been loving it, but after about 40 miles of riding I've noticed there's a weird grinding/rubbing feeling coming from the right side of the wheel. It only happens when apply force to the right hand side when turning or carving. At first I thought it may be something stuck in the fender as that used to happen with my S18, but all was clear. I took a deeper look when I got home from our group ride last night and it looks like something may be rubbing against the motor (see pic). I don't see anything sticking out near the wheel though. If a light rider is on the wheel they have no issues, but anyone about 200 lbs was able to replicate the issue I was hearing/feeling. I've reached out to AR, but figured I'd check with the Forum and see if there may be something I may be missing. Guessing I'll be taking it apart and checking if any screw or casing is loose. At this time I've not had a single accident or fall so the wheel is still in perfect condition. any input is appreciated!
  3. Good day all, new member and new rider here. I've been learning on a borrowed KS-18XL and had the opportunity to pick up a second hand one in great shape so I have. So far very happy except that the headlight on the one I bought is utterly and completely useless - the output is just nothing like the other one (or what it is supposed to be, based on looking at others' comments and reviews). The obvious fix is to replace the headlight module (not especially costly, so no huge deal) but first I wondered - has anybody here tried to replace/mod for even better lighting? If so - what did you do and how is it working? If an upgrade can be done instead of just a "repair" I would likely go for it, any input appreciated. Thanks!
  4. Hi all! I'm coming up on the ~2,000 mile mark on my MCM5 and I think it's about time to do a serious sweep through of the wheel to make sure everything checks out as it should. I had the idea to do this and create a thread that can be a sort of go to for other members looking to check out their wheels, but it's also to help me understand a few things I'm not sure of. The goal here is to allocate all of the information associated with wheel maintenance so that it saves everyone lots of time when it's their turn to do the same! Keep in mind that this is a work in progress and will undergo many formatting changes and additions to the info found here. A lot of what you'll find has been taken from info supplied by other people and keep in mind that everything you read is probably not supplied by an expert, although there's bound to be a bunch of info that is!

Some basic troubleshooting steps if you think you may have battery issues or just want to check out how your batteries are doing! If using an app to check our your voltage other settings, make sure the app is set to your wheels proper specs. I made this mistake and its a simple check! Using a multi-meter (linked below), check to make sure your charger is outputting the advertised voltage! Copied from a post below (credit to Chriull & Raging Grandpa)... First check the charger no load voltage. Then the fully loaded battery output voltage (to act as a... control of the voltage measurement on the mainboard). If this is ok it ought to be one of the battery packs. Separate the packs and try to charge them individually - in most cases only one is bad. To do this, unplug and charge up one of the packs. Then test. Do the same for the other! Replace the bad one with a new one - and ensure they have as good as the same voltage when reconnecting! If one is experienced enough one can replace the bad cells of the bad one instead of getting a new one. But since one most presumably has no possibility to do proper cell matching this repaired pack will not last as long. But it will be much cheaper... (see the link on testing out different cells below for more info) Description of BMS & Battery relationships "It's slightly more complicated: your BMS ("Battery Management System," a circuitboard contained in the pack) is detecting that some cells are 'full' and is stopping the charging event. When this happens, the indicator light on your charger will go 'green' - but the pack voltage never got near 84V." - RagingGrandpa How to replace a battery pack! "(Pack replacement)..It's quite simple- the pack is a module that can be unplugged from the EUC. Plug in new pack, close up the plastics, done" - RagingGrandpa Testing out difference cells... "If this is all brand-new to you, I don't recommend doing it... save yourself a few skin burns. But to answer your question: we suspect you have some cells at 0V. To confirm it, you would need to measure the voltage of each cell... but in all cases, pack replacement is the answer." - RagingGrandpa A thread that goes into much more depth or testing different cells Supplies needed/Voltage Tester Etekcity MSR-R500 Multi-meter recommend as an entry level and budget friendly option by RagingGrandpa Flukes Digital Multi-meters recommended by a (mechanic?) as a higher end very reliable option - ShanesPlanet This thread goes into the dos and don'ts of using multi-meters! -Chriull Where to sell old battery cells/any other old or damaged parts?
