I am looking for a used, faulty, broke euc. Not model specific as i want to try one out without scaring the wife with the cost 1st, so the basic idea is to keep the cost low to show how good it will be then upgrade to a decent one! I’m an electrical controls engineer and can fix pretty much anything really. thanks
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...
