It seems okay so far, but I’ve only done some small hops on it. ---

Wow, that is some skillful riding indeed! 🤩 That is a quite interesting setup. So little leg movement, suuuper smooth and a quite decent gain ratio as well (~36"/114mm). I am not the least surprised to se that downhills poses some difficulties. Time to install som brakes! 😉 But seriously guys, you don’t jump mount and hop on these cranks!! That is _begging_ for trouble! 😬 Also, the mototiger 45s and the 45s @Syoten found are identical. The only difference is the brand logo. Now put these 38s, or maybe the 45s first, on a 16" and let him have a go! 🤩 ---

Do you have a photo of how they deformed? Because they are so short, I thought they are rather strong. ---

They deform inside around the hub, making more room and you feel the cranks wobble while riding. You have better shims than our plastic shims though. Could you please share some more details/photos regarding your shimming? - Material, thickness, size of shims - how you placed them on the hub or in the cranks, etc - do you often need to retighten them? ---

I just cut a piece of iron sheet from an iron box. It’s pretty thin. I don’t have a caliper ruler for exact thickness measurements. How I shim depends on the size of the cotterless axle. My 12" unicycle has smaller square tapers, so I wrap a piece of iron sheet around all four sides of the tapers. But my 16" unicycle has a bit larger ones, so I just put two pieces of small square iron sheet on two sides of the square tapers. I first put a part of the shims on the cranks and another part on the square taper, then tightened the nuts. I tightened the nuts quite hard and haven’t retightened them yet, maybe because I haven’t ridden them much. ![20250608_161639](https://unicyclist.com/uploads/default/original/3X/7/2/722e4fc25fc6809e82a6653374be9eee8b66dd67.jpeg) ![20250608_162409](https://unicyclist.com/uploads/default/original/3X/a/3/a3bdc2471b9379a4f210aa3d1c1a083bdb2bf361.jpeg) ![20250608_162014](https://unicyclist.com/uploads/default/original/3X/8/a/8a107a58080c2885c917befdfa4c88002fee121a.jpeg) ![20250608_162212](https://unicyclist.com/uploads/default/original/3X/b/5/b5a8f97e26767d105881fce0e1a44a42dd84b0fd.jpeg) ![20250608_163409](https://unicyclist.com/uploads/default/original/3X/1/e/1eb13a7147cbd2bdcc5b5062c63d37c27f9dd08d.jpeg) ---

Sorry, no photos but they deformed as @PedalSprell wrote, but also the pedal hole ---

Ok, Ok, I know it has too many wheels… but… the cranks and wheels are really small. Does it count? ![Man on a pink and white tall bike with tiny wheels in front of the Royal Palace in Oslo](https://unicyclist.com/uploads/default/original/3X/c/0/c0de16a7fe51e16a5167623b9080ae4c5d147546.jpeg) ![Man on a pink and white tallbike with tiny wheels in front of the Oslo Opera House](https://unicyclist.com/uploads/default/original/3X/2/4/249ffaab5d891be5f886691ed08c7a99fda1654e.jpeg) Also, I look like a freaking gangsta! ---

I don’t think it is high enough. you can build another frame on top. The horse still looks down to you. ---

I have ridden a couple of tallbikes before this (all built by @objorke, including this one). Strangely enough, this is the tallest one! 🤣 ---

Nice choice of colours… Even though it is a bit scary to climb on top, once you’re past that, it will feel just like riding a bike I reckon. Just mounting and dismounting it is a problem. You can’t just take it to the supermarket. On the other hand all that extra space below can be filled up with storage space. Then you can really plunder the supermarket and quickly race home 😃 ---

You are not quickly racing anywhere on this. It has the orginal gearing of the kids bike it is built from. If you just cycle “normally” you are going walking pace. If you cycle fast, you still aren’t actually cycling fast. Your legs are just spinning. 🤣 But speed is not important. It is all about style 👸 💅 ---

Im aware of that. Was merely imagining it like a cartoon with the wolf from Road Runner on a kids bike. You have the right face for that 😛 ---
