  1. Hi, everyone, Rockwheel has been created for the fifth year, and it is honored that it has not yet closed, after all it is not a profitable industry, in 2012 I had the first Solowheel wheelbarrow after the start of 2013, I gave up The original business, all devoted to the start of the operation of Rockwheel, because I love, my first wheelbarrow is gear motor drive, because I like it to accelerate the sound of metal roar, so I named Rockwheel. Natural air-cooled system, we tested 30 minutes of continuous climbing, the controller temperature of 58 degrees Celsius,
  2. So I bought a second hand GT16 for about 900€, it had 74 km on the clock and no real dents or scrapes. Given a new one in EU would cost close to twice that amount I took a chance, knowing full well that my frugal side could come bite me in the rear if I were unlucky. I got it on eBay from a seller with 60-ish positive comments and no negatives. I got it pretty fast, about a week from payment to delivery, and unpacked it with some trepidation and a suspicious mind. The positives were: It had no real dents and scratches except for on the pedals. It started OK, and balanced perfectly The app connected without fail, and the meter matched the pictures on eBay. It came with a trolley. The negatives on the other hand: The trolley was partly broken, but fixable. The LEDs on the sides were not connected, and there is not even a cord to connect them to unless that is stuck in the controller compartment. The mudflap is just as useless as people say, I'll have to look into what can be done about that. One of the plastic dampers for the pedals were missing, I fixed it with a skateboard riser. The same pedal were loose, meaning would not stay up when risen agains the shell. The shell sat somewhat loose on the wheel, it seems the screws connecting the shell to the wheel were not tight enough. Some of that is the breaks of the game when you buy second hand, but a few points were a bit worrying. Standing with my weight on one of the pedals the first time made the tire "screech" against the shell. The dreaded "cracked axle" ghost raised its head grinning my way. But as it turned out, the reason were fourfold: One - the air valve stuck out a bit too much, two - the screws to the shell needed tightening, three - the shell is not as rigid as it should be, and four - the tolerances are too small. The last aspect is my main negative feeling about the wheel, it could well have a quarter-inch more space around the tire on all sides, where the tire meets the shell. That would make the mudflap immensely more useful, would eliminate the risk of the valve or the sides of the tire rubbing against the shell, and maybe even allow a 2.5" tire upgrade... Also, the screws connecting the shell to the pedals, which AFAIK are the only twelve screws that hold the shell to the wheel, doesn't even have washers. Basically the screw sits directly on the shell, which seem outright stupid. A metal backing, washer or a plate, would spread the forces over a bigger area, making the connection stronger. Four of those are the bottom screws that sits below the pedals, and there is no form of metal backing there either. Sure the forces push the pedal towards the shell, but there are side-forces too. I fixed the trolley with loctite, a cable tie and some really strong weave-tape. I also added chrome strips, to avoid my clumsy self killing the beauty of the wheel. The loose pedal turned out to be a combination of the tightening screw being loose enough that the pedal axle had moved around. So when the previous owner tightened it, the flat part where the adjustment screw should grip had slipped around. Taking it apart, and putting it together correctly solved the problem beautifully. I added skateboard gripping tape to the pedals, the really rough kind. You can't see it on the pic, but there is some silver tape on the shell under the pedal to avoid imprinting the grip tape on the shell. Will get rubber stickers or something to replace it with. Now to learn to actually ride the darn thing... I now realise my Inmotion V3 have given me some really, really bad habits. The first half hour, in the middle of the night, were like going to the bloody gym! Today, the second day, I actually got on unassisted for the first time and rode my first ten meters before a controlled stop. Good exchange for 45min of trials, still exhausting though. There's still a lot of familiarisation to do, and a lot of twin wheel stupidities to unlearn, but I see the light at the end of the tunnel. With this tempo I will be zipping around in no time The bad habits to unlearn are: almost no leaning of the wheel before getting on; getting on first, then start rolling; going really, really slow – plus the lower center of gravity on that wheel with lower pedals and 14" wheels. I look forward to getting used to a "true" unicycle. I'll report more as things progress...
  3. Would love it if anybody could give me a clue on some things to check on my rockwheel, I pressed power button and got nothing, so I figured I just need to charge it. When I plug in the charger, the indicator light on charger stays green. I unplugged the charger and pressed power button, and I have a fading beep sound and charge indicator drops to empty almost immediately. Any ideas, I left it on charger for 30 minutes, light remained green on charger the whole time and when unplugging and then pressing power...same thing. Battery seems to not have charged more than the beeping and light that immediately goes off. By the way, the battery was great before and still was holding full charge.

  5. So, as I wait for my GT16 to arrive (ETA next week), ..... Dug up an interesting tidbit from a Korean NAVER Blog GT16 Review [source] [google-translated] about the GT16 having app-less balancing / leveling capability: Turn off GT16 Turn on and hold GT16 until the last prolonged beep, then let go (sequence will be 4 short, consecutive beeps, then 1 long prolonged beep) Level the wheel Press the power button. Wheel will now be balanced. Apparently the previous Rockwheel TB14 had the same function.
  6. Hey, Does anyone know where I could get a replacement battery for the GR16? I bought one used and it only charges half way. Also a more powerful battery wouldn't hurt I guess. I saw one guy that retrofitted one of these LiPo batteries, but I´m not sure which one to get. Best Regards K

    Hello, might be question hard to answer, but which euc is the fastest right now on the market? Top 5? thanks for your reply.
  8. Hello I "upgraded" from the Airwheel X3 to the Rockwell GR16. The bump up in speed and acceleration is really awesome. However, I have noticed of late that the gyro calibration on my Rockwheel is probably a little off. Let me try and explain what I mean. I usually ride with the battery/LED indicator on my left. Nowadays, when I switch over and ride with the battery/LED indicator on the right, I feel that the pedal is a little off and not completely level. With the LED on my left, I feel that I need to lean forward less to move forward when compared with the LED on my right. If the calibration is accurate, there should not be any difference. How do I check if the calibration on my Rockwheel and make the necessary correction/adjustment (if any)?
  9. Hello, I am so excited about these! I have never seen one in my life b4 a few days abo I spent the next 9hrs researching these and I want one! I live in up state NY near the capital which is Albany I have no Idea where I can find a place where I could go physically buy one of these I Tryed googling shops or rental in NYC because I have to go there this weekend and I found nothing but dead ends. I also have a small 2 day vacation to niagra falls Canada but have yet to find anything except that they might have them at best buys in Canada. I almost bought one from altybaba.com but it concerned me how cheap it was and the method of payment that they wanted money order or western union didn't seem legit! Where are some dealers in the U.S.? Or even near the Canadian border? Can I rent one anywhere in the northeast u.s.? Im about 230 lbs so I probably need a decently powerful one way would b suggested? Seems like the rock wheel is the strongest and fastest from wat I have read and watched on YouTube is that true? Would you suggest buying a cheapo to learn on? Would it run ok w me on it even tho I'm 230lbs? Can anyone hook me up with any legit dealers of either cheaper ones that r still ok to learn ok or rock wheel, or gotway?
  10. The wheel caught on the molding and cracked body by the foot stands. Is there anywhere to order body or any suggestions?/ please give me some type of hope

  13. Hello everyone! I've been looking for a better EUC for while now. First I purchased an entry-level EU, similar to TG wheel (14"), since it was light, temperature range -10 to +40 C and low cost to learn. But I like to drive some trails too, so like to get more power and bigger wheel. My first thought was to get a 9bot1 but after I tried C+ I was dissapointed: pedals incline to driving direction ("soft" feel), which didn't feel nice, I liked to have a firm (firmer at least) feel. I also didn't like the tilt-back, especially when it occurred already on relatively low speed. I have no idea how big changes can be made via Ninedroid or how big the difference is between C+, E and E+? The I seriously considered to purchase IPS XIMA Lhotz (191) and e-wheelshop.nl came up - have anyone any experience about them? It there a risk to get one older version? In that case, will it still run 30 km/h? What is the actual range of this wheel? Which parameters can be varied through the app (and which app)? Is it really waterproof, like 9bot? Just keen to that 2,5 inch tyre, could be a beast on trail... Now I have Rockwheel GR16 on test and I see many pluses, but perhaps still more minuses on it: + really light, as TG + range about 3x vs. TG - almost OK, but there are many other comparable choices too + open casing makes it easy to remove snow + incredible torque, so easy to start again after landing... even from a small hole - very unstable due to lack of angular momentum/geared stucture (?) - revs instantaneously when even slightly airborne (due to the great torque) - difficult to balance when compared to TG 14" or 9bot - terrible clearance to to the gear, several degrees, makes it difficult to make tight turns - bad noise under bigger loads, especially today when driving in -30 Celsius uphill Any of these familiar to others who tested RW? So what wheel should I choose, any recommendations? And please do not suggest any 18", since those are just too high and big for me, I don't want the wheel reach above my elbow. Thanks for reading through, please give me a clue - Tuija
  14. I wonder that no one seems to have a gearless rockwheel GP14 ? I think it's one of the best 14'' with more than 35kph top speed.
  15. So the time has come for the world to finally receive a proper review of the Rockwheel GT14, and it really does deserve a review! First of all: This is currently NOT the wheel for someone who wants to unpack their new wheel and ride without any worries, however, it has a great value-for-money (may be the best) for those who know their way around a screwdriver and a solder iron First impression of product&company: So I had not owned a Rockwheel, nor had I tried it before this one. Because of the problems with the geared versions, I was skeptical towards the brand, but the GT14 was supposed to be the debut to elbow its way into the international market. It was ordered straight from the factory, and Sunny was my contact person. It took 2,5 months from I paid it until I got it, so I was pretty angry in the end. The reason it took so long, was because of delivery delay from the factory in the first place, followed by an error made by the forwarding company. On top of this, follow-up was poor because Sunny had quit her job at Rockwheel and were sporadically following up old customers. Anyways, the wheel arrived yesterday in good condition. When unpacking the GT14, it strikes me that it is much more attractive looking in real life than it is in the pictures. It is kind of a stealth look with that matte, wide, carbon fiber painted shell. I own a Ninebot One, and while that is a beautiful wheel, I never felt entirely comfortable with the looks of it. The MCM4 looks like a funny toilet seat with LEDs to me. This looks more rough, more towards my taste. With the wheel came a fan-less charger. It is only rated 2 amps, so it is not as quick as the more noisy 5A chargers. The only other thing inside the box was a service record leaflet, no manual, so you have to figure out the rest by yourself. A high quality CST tire is fitted, and the foot rests are wider than usual, making it more comfortable to ride @ high speed. There were also magnets to lock the foot rests in place (thank god). One pedal was not aligned properly, so I had to take the shell off and fix this. Otherwise the unicycle was properly bolted together, and there was used silicone instead of glue on all connections which is a good thing. Modification that MUST be done before even thinking about riding this unicycle: First ride with the GT14 was with mixed feelings. I had been reading about people being face planted on this model, but I thought it might had been solved with the latest motherboard revision. WRONG! After I rode up a steep hill, I got face planted @ moderate speed, and the wheel was dead afterwards. I immediately suspected the BMS, and I was right...Rockwheel engineers made one big mistake with this wheel, and that was using a cheap, under-rated BMS for this unicycle. The BMS board has 3 parallell under-voltage protection MOSFETs installed, but they just could not carry enough current to feed the motherboard/motor. Because of this, these components died, and 2 diodes in parallell with these also blew: Make sure you do the shunting mod to this BMS before you ride. This will prevent the wheel from shutting down, and you getting face planted! I recommend running 2 or 3 wires when shunting, just to make sure you are getting enough current to the motor, better safe than sorry. Ride quality: At first I though the GT14 performed horribly. It was stuttering at low speed, the pedals were not aligned horizontally, and it was very hard to turn around tight bends at low speed. It could simply not be compared at all to the NB1. This was, however, until I got it set up properly. I tried the Rockwheel app which crashed every time, so I downloaded the Gotway app which connected to the wheel just fine. After an alignment calibration, the wheel felt much better instantly. I still did not like the extremely hard ride quality, so I changed the ride mode to "soft". Now the wheel was actually performing very good. It is still not as refined and smooth like the NB1 by far, but it is just a different beast, a little more rough around the edges. The tall body means that you will press it between your legs further up, which in turn gives you more control over acceleration and braking than lower body wheels. Turning capabilities with this wheel at low speeds are not good. The pedals are spaced wide and low, which means that tight turns will make the pedals scrape against the ground. After a little practice, I actually learned to turn the wheel just fine, one just need a little different method. I think that Rockwheels intention was to make this a high speed commuter, and that is just what it is. The wide and low pedals make riding at high speed more stable, so it is not all negative. Overall I am very satisfied after setting up the wheel properly. Speed, power and battery life: The GT14 is a beast. The acceleration in this wheel is extreme, making the NB1 E+ feel like syrup in comparison. Uphill, the motor is also considerably stronger than the one in my NB1 E+. It has got the ability to run very fast, and although I have not tried yet, I have no doubts it can reach more than 35km/h on a flat surface. The battery pack in mine is 355WH with LG cells. The milage is impressive. I have not tested it long enough yet, but the milage seems to be around 50% better than in my NB1 E+. There is also additional space inside the housing to fit one more 32 cell battery pack, so you can upgrade this to more than 700wh capacity. The battery is placed horizontally over the main board. This might be a smart solution, as heat from the electronics cavity may help to keep the battery tempered during running in cold weather. Safety: There is no doubt that there are safer wheels out there than this one. This is not an euc for beginners, but for the professional rider. It has a slight tiltback, and audible alarms, but it does not seem to have any hard overspeed tiltbacks at all. However, with the BMS shunt mod, you should be safe as long as you run sensible. I got my heart pumping yesterday when hitting a pothole at very high speed past critical speeding alarm. The wheel got tilted forward, so much I almost lost balance and fell off. Instead of turning off, the control board provided the motor with maximum current, and luckily I caught balance again Bottom line: As mentioned earlier, this wheel is not for the beginner who wants to unpack their wheel and ride. If you know how to handle a solder iron and want to do the BMS shunt mod, this wheel is probably the best deal currently available, price vs. specs/features. It would fit best for the serious commuter, rather than those looking to play, jump and do tricks with their EUC. At 150-180USD cheaper than MCM4, you even get 15wh more battery capacity. The carrying handle is a bit oddly shaped, so carrying it far is not comfortable. Weighed in at 11.6kg, it is not very heavy regarding the battery and motor size. Bottom line, I think it deserves a lot more attention than it has got. Rockwheel got very close on this one, but still so far away As long as you do the BMS shunt and alignment/settings tweak, it is a great wheel for the price in my opinion

  17. Hi fellow unicyclers, I would like to post a warning towards buying anything from Sunny rockwheel here on the forum, or directly from the factory (in where she is employed). I paid for a GT14 unicycle more than 2,5 months ago (yes you read it correctly) by wire transfer to Sunny rockwheel. First of all she did not keep her shipping date at all, it went weeks after weeks before it was shipped. When it first shipped, their shipping agent messed up so that the unicycle stopped in Germany for some reason, or at least that is what it seems like. I have been pushing for over a month on Rockwheel to fix this, either send me a new wheel, find another solution or give me my money back. All I have had from Sunny is excuses that it is their shipping agents fault, and lately she has not even answered my emails. This is starting to look like a big fat scam to me....She was very eager to take the money off my hands, but when problems arise, there is not much help to get! I advise anyone to not buy a rockwheel product, and especially directly from the factory, because with wire transfer, your money is lost if something happens Anyone else has had trouble? Please share! Here is even the proof: https://www.fedex.com/apps/fedextrack/?tracknumbers=774419862103&cntry_code=us
  18. Hi,I am Sunny from rockwheel.Our new model accept orders now. Send message to me if you are interested in Rockwheel GT14 Of course,don't forget our classic GR16
  19. Hi! Rode my GR16 yesterday and at the end of the run it started tilting backwards and forwards. It´s like it´s trying to find the correct level but misses every time, going back and forward. Kind of scary feeling. Anyone got any suggestions on what could be wrong? //GR16
  20. I'm interested in trending electric unicycles in Hawaii, is there anyone on this board who ships containers direct form the manufacturer?
  21. ​I ride my wheel almost daily and often think about features I wish it had and have been making a wish list in my head. I was curious what features other riders wish were standard features. WishlistAbility to turn off speed beeping Nothing is more annoying than the beeping when you are on a ​clear stretch and accelerate up to max speed and the wheel keeps beeping at you. I like that it's a safety feature, but I'd also like the ability to turn it off. Ignition key to l​ock ​wheel Wheel security (theft deterrent) is an area that I think is significantly lacking across most wheels that I've seen. I live in New York City and need to be able to secure my wheel when I ride from home to another destination. An ignition key would be a great start! Anyone can take my wheel and glide away with it without the need of a key. Mechanism to chain it up to a secure place (pole, bike rack, etc.) Another security feature. A major selling point of all wheels is their portability to lift and carry short distances which makes them easy targets for theft. Many wheels have a handle that can be used to secure to a pole with a cable, but some don't like the Ninebot One series. A built in cable would be amazing. Storage solutions I need a place to store my cable to secure the wheel - or other small items I don't want to carry on my person and otherwise don't need to bring a backpack. This is less critical than other feature and could be solved with an aftermarket accessory, though I haven't seen one yet. Braking (and headlamp) lights as standard features My Firewheel has these and I love it. I have been researching a second wheel to buy and wish more had this as a standard feature. Smartphone app as standard feature ​ ​Another feature that more manufacturers are providing, but wish it was standard for all wheels. Being able to see the stats on my wheel's speed, battery life, etc. is an awesome feature. What else?
