Has the MCM5 "retired" any other EUC's for you yet? Or perhaps asked a different way, I wonder if you would rank your EUC's in order of preference for which you'd grab to go for a ride most often? Or maybe how you think of them and choose which your are riding which day for what reason? (Hoping for delivery on my MCM5 about in 3 weeks). No, the bloom hasn't faded. Frankly, at this point it's impossible for me to rank all of my wheels. I love them all. I thoroughly enjoy the variety. Sometimes it can be a month until I ride a particular wheel and then it feels like I just got a new wheel again, and I have a bunch of fun. I grab any particular wheel based on the terrain that I'll be riding on and how I feel that day. Like having a closet full of cloths, you pick what tickles your fancy for the day. 2 3 Quote Link to comment Share on other sites More sharing options...

If you notice, @Marty Backe has two of same wheel the ACM2. I too love this wheel how smooth it rides, matte black finish matches my other hobbies... Simple, no nonsense durable design is definite plus. So far my cruising speed is around 15 mph (don't have Marty to keep up with around here lol). p.s. No battery anxiety for me at least as if this thing will go forever... Edited June 10, 2018 by Mark Lee 2 2 Quote Link to comment Share on other sites More sharing options...

Yes I charged the wheel and took it for a spin yesterday. Check out The Video Thread. @Marty Backe did a great job on his review but here are a few other things I noticed. The wheel lived up to my expectations of superb power and handling. The ergonomics of the side panels and lack of calf padding was quickly resolved but the little bump with the Gotway logo does not feel comfortable to my ankles. When I switched over wearing to boots it was more tolerable. Strange place GW chose to place a big pimple as the medial ankles are the most prominent of the foot. Not sure how well the plastic trolley handle will hold up due to the thinly sculptured structure but it conceals nicely into the rest of the shell. The configuration of the MCM5 shell does not allow for the handle to be accessed from the other side so any tethering would be difficult. I still need to get use to performing reverse 360s without destroying the shell. As for the identity of red molding I need to look at the box which is at work. I’ve had it for some time.

beast@tanagra Posted June 11, 2018 Share Posted June 11, 2018 I remain fascinated by this wheel. How's she holding up to the abuse? Before you had taken her into the hills, you had commented on one of your youtubes that it didn't seem like it would be as durable as, say, your 14S. Are there trail conditions (besides very long distance) where you would feel better on one of your other wheels? 1 Quote Link to comment Share on other sites More sharing options...

I've dropped it multiple times on trails, etc. Seems tough enough to me. The more I ride wheels and different wheels, the more I feel that they are all tough. Some shells might not be as tough as others but the basic functioning of the wheel (any wheel) can take lots of abuse.

Popular Post Mrd777 Posted June 14, 2018 Popular Post Share Posted June 14, 2018 (edited) I just want to reiterate what @Marty Backe has been reporting on this MCM5. I've only had it for a few days now, buying after I turned in my failed V10F. The wheel is fantastic, absolutely loving it, Its a fast and agile cat. I haven't taken it on long ventures yet, however it certainly is a winner for quick jaunts in NYC. I'm so glad I purchased it. Thanks Marty to opening my eyes to this one!

I hope to be in this club soon, but I think I'll need to wait for the slowboat from China to bring eWheels its (800Wh!) shipment. Got my Glide 2 (V5F) yesterday for the kids, took it for a test spin after inflating and calibrating, and really fell in love with the 14-inch category. I found it much more intuitive, coming from the MTen3. My son, also an MTen3 native, took to it immediately, and was looking like a pro within a couple of hours. 3 Quote Link to comment Share on other sites More sharing options...

esaj Posted June 14, 2018 Share Posted June 14, 2018 (edited) I was wondering about the ACM2-thing, like why would Marty prefer a bulky box-type 2014 / 340Wh wheel capable of something like 25-28km/h... then realized I'm thinking of MCM2 Edited June 14, 2018 by esaj 1 Quote Link to comment Share on other sites More sharing options...

I wonder if they ever will devise an external battery supply port so people can bring along secure battery packs in backpacks for extended range. That would be another game changer for some people, and it would offer flexibility. It could take that light weight MCM5 and make it a 60 mile wheel if needed. Maybe some sort of quick connect with a safety disengage system in case of a fall. Velcro thigh strap to keep the wire tangle free. It must be electronically possible somehow with some of voltage matching circuit? @esaj queue the electronics theory talk! Well, yes, I can think of a couple of ways of doing this of the top of my head, but they all come with downsides: Charge via external pack while riding: Relatively simple, all you need is a battery pack and a step-up converter with current limit (could be just a current limiter without step-up, but it won't charge if the external pack voltage is below the internal pack, and needs to dissipate a lot of heat when the internal pack is more empty), preferably also some sort of low-voltage monitoring so that the converter cannot overdischarge the external pack (unless the BMS already handles that) Some form of "safety quick-release connector" that disconnects under certain force in the wiring should be possible, as the current isn't that large (likely the connector couldn't handle much current) Won't charge as fast as you're using power a lot of the time (limited by the charging port/internal wiring from charging port to internal packs), so you might still have to stop sometimes to wait for the charging to "catch up" Definitely the safest of all of these methods, even if the external battery disconnects mid-ride, nothing really happens (except the internal pack stops charging) Directly feed the power to the wheel from external pack A bit more complicated, for the external pack you just need a high power connector (something like XT-90 or EC-5 @ 120A max comes to mind), but... Unless the external pack is at the same voltage as the internal pack when you connect, you must first disconnect the internal pack, otherwise the voltage difference will cause a very high current, which can damage your wheel mainboard (through inductive voltage spike from the fast current raise) and/or battery packs or even cause them to catch fire or explode The "mechanism" for disconnecting the internal pack becomes a bit troublesome, basically you'd likely need to open the wheel and disconnect the battery connector(s) of the internal pack(s) No "safety quick-release connector" could be really used here, the connectors capable of handling high current have low resistance, which usually means that they are very tightly connected (think how much force you need to disconnect an XT-60), so in case of a tumble, or if you dismount and the wheel gets away from you, the wires might break or pull you and make you fall Long wiring can effect the voltage at the wheel end, and adds stray inductance in the circuit -> might need more/larger capacitors at the wheel-side? Feed the power to the wheel from external pack with step-up / current limitation Similar to the above directly feeding from an external pack in good and bad sides, but internal packs don't need to be disconnected Both charges the internal pack (when the voltage drops/tries to drop) as well as feeds power to the wheel Bulk of the power still comes from the internal packs, as the external packs cannot produce more than X amount of current (which must be less than the internal packs can take in charging, as the external pack converter/limiter won't "know" if the current draw is caused by the wheel motor needing more power or because the internal pack voltage has dropped causing higher current) Still needs a relatively high current connectors (GX16 won't do, otherwise you might just as well use the charge port anyway) Might need some reverse protection or large caps at the external pack-side, regenerative braking might push the voltage at the converter to high values momentarily (not sure how a switching mode power supply would react to that) For all of these, I'd still want the external packs to be hard-cased, the usual heat shrink wrapping around the packs doesn't do much more than keep the cells and the BMS together, it won't stand a direct hit should you fall. Also the cable harness would make things more awkward (can't have really long cables, as they'd get in the way/under the wheel, but if it's really short, you need to be standing /crouching on the wheel when connecting). And this is just quickly off the top of my head, so I might have overlooked some blatant safety issue, and I wouldn't suggest trying any of these without some further planning Edited June 14, 2018 by esaj 5 Quote Link to comment Share on other sites More sharing options...

It's more perky in its acceleration and much more agile. Certainly seems to run cooler since the KS14S overheated midway up Overheat-Hill yet the MCM5 only got into the low 50's at the top of the hill. Hard to quantify for sure, but I get the sense that the MCM5 has a lot more torque than the KS14S. 4 Quote Link to comment Share on other sites More sharing options...

The KS14s is an 800W motor with a maximum of 840KW backing it up. The MCM5 is a 1500W motor with a maximum of 800KW. So motor tweaks aside, and assuming nobodies lying and everybody is using the same math, generally the MCM5 ought to have 2x the ummphf. 1 1 Quote Link to comment Share on other sites More sharing options...
