TheExtreme Bull keeps getting better with the release of the K6. It's the first of its kind with a unique form factor inspired by sitting scooters but with a far more relaxed riding position and lower center of gravity. Combined with the extreme power this makes the Extreme Bull the perfect scooter for mobbing around town! Our new K6 version now sports a more refined frame, upgraded suspension, and higher voltage lithium iron battery.
Now with Samsung 40T cells and a more comfortable seat!

I had some discussion with ex30 owner and he express idea that c38 motor is mor efficient. I did 46km today with average speed 40.5km/h and battery drop just to 123V. It seems pretty good to me. I guess i will be able to go 100-110km. But still, can you compare range with previous version of CPro?
My Cpro is not able to full charge. It will go slightly over 133V. It is not big issue to me, but key question is, if the electronics can still balance battery packs. Are you able to full charge of your CPro50s?
To me that looks like they are planning on a smart BMS, but it is not polling in this firmware version. If they do get the polling working, I would bet the individual cell voltage could be possible with the right firmware. The real question is, will begode use that feature .
Also not getting the full 134.4, only 132.2. But after researching more it sounds like it's normal, according to Marty's videos and early forum discussions. Will try ningning dual charging to see if I can get it higher. Some have said to unplug after hitting 100%, then plug back in. But very conservative safety margin imo if that's what's going on here.
Tire change is easy to open up the wheel "spread eagle" without pulling cables, which is great. But finding a 90/90 tire that fits has been a bear, even with mudguard rails adjusted. Tried the k66 90/90 which does not have the clearance between the batt boxes, so running the k66 80/90 with Roger spacers, which I'm getting used to but really fights a guy in high speed turns.
But the biggest issue is that I have a noticeable "sputter" especially apparent when hammering down on the throttle, either at speed or at take off. Firmware has been fully updated, happens in off road or race mode, stock and other tires, uninflated massage reinflated, doesn't matter it's still there. It feels like a bunch of mini dips in succession. Friends didn't notice it, but we were on bumpy roads so, and it's my 8th new wheel in 3 years, I know what I'm feeling. Feels like a power distribution issue from the board idk? If some of you can try heavy accelerating your 50s on a nice smooth road and report? That would be helpful.
Other small things would be the weak headlights and taillight (maybe the EX30 taillight could be used?). And some important functions of eucworld are unavailable, not to mention app crashing (Seba is working on it, said an update is coming this week). Other than that, what a fun friggin wheel. Oh the power..
Cpro 50s owner here. I was one of the first to purchase this particular wheel through ewheels according to Jason. In a word, it's an amazing wheel. The handling, speed, suspension and breaking are excellent. This is my 2nd wheel my first wheel was the V12 HT and it's a night and day difference in stability. Don't get me wrong the V12 HT is a great 16inch non suspension wheel. But, the CPro is on another level. Now, it is a bit of a heavy wheel in comparison and you will need a few miles to get fully accumulated but, once dialed in, it's so smooth. Shout out to Ronin Ryder, I met him one day at "I-rides" and his review is spot on. If you turn on the magnetic weakened to 9 it really helps with easy acceleration. The Bluetooth speakers are actually really good or, at least better than I expected.
Now, their are some negatives about the wheel that I wish could or was addressed before. Like,for instance, the dashboard, it's useless and you definitely need the app to monitor your speeds. Apparently, the BMS also isn't active which was promised and the charge port cover works but isn't great. Finally, the Begode app setup was veryfrustrating. If you do get this wheel, make sure you get the verification in your email within the sixty seconds. Otherwise, you may need to create a new email just to get another access code. But, Bruce from Ewheels was patient and very helpful as I'm not the youngest or most technically savvy guy. I've only put 300miles on it so far and I'm still using the stock pads. Which are adequate but not my ideal set up. Their are other wheels, and some yet to coming to market but, the Cpro 50s is in a class by itself with its watt hours, suspension, battery, and C40 motor.
The Castle 2028 Extreme 800KV motor now has an IMPROVED 4-POLE 12-SLOT design that boasts exceptional EFFICIENCY and produces LESS HEAT. If you need LARGE-SCALE POWER for LARGE-SCALE VEHICLES the new BRUSHLESS SENSORED 2028-800KV motor will no doubt hold up to the heavy throttle and extended usage that 1/5th scale vehicles like the Losi 5IVE-T, 5IVE-B or DBXL-E encounter. It is the perfect upgrade for any 1:5 scale RC hobby vehicles (including gas to electric conversions) weighing up to 30 lbs for 2WD and 25 lbs. for 4WD. The 2028 Extreme can easily run in the 10 horsepower range*
Running modes: Sensorless and Sensored
The 2028-800KV is a water resistant design. The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. We recommend applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments.

The mechanisms underlying the chemo-mechanical coupling of motor proteins is usually described by a set of force-velocity relations that reflect the different mechanisms responsible for the walking behavior of such proteins on microtubules. However, the convexity of such relations remains controversial depending on the species, and in vivo experiments are inaccessible due to the complexity of intracellular environments. As alternative tool to investigate such mechanism, Extreme-value analysis (EVA) can offer insight on the deviations in the data from the median of the probability distributions. Here, we rely on EVA to investigate the motility functions of nanoscale motor proteins in neurons of the living worm Caenorhabditis elegans (C. elegans), namely the motion of kinesin and dynein along microtubules. While the essential difference between the two motors cannot be inferred from the mean velocities, such becomes evident in the EVA plots. Our findings extend the possibility and applicability of EVA for analysing motility data of nanoscale proteins in vivo.
