Bike stands are dope. I had always thought of them as unnecessary (because you can do everything without them), but once my parents got one and I used it a few times, I had to get one myself. It’s more game changing for working on bikes IMO, but I find myself using it for the uni a lot more than I thought I would.
Another big change for me was starting to use power tools on bikes and unicycles a lot more. Some people are going to think that is a wrong thing to do, but I think it’s really a massive time saver. I start and fully tighten all bolts by hand, but for unscrewing bolts and running them down I love the small battery powered drill.
I had the same experience after switching to hard soled shoes that I bought at a skateboard shop. They were Vans and they work great. A lot better feel and more power to the pedals.
For something like running down spoke nipples I definitely use a drill, saves a ton of time, especially if you lace it wrong repeatedly🤣 It also doesn’t matter if you slip off the nipple with a flathead in a drill since you’ll only scratch the inside of the rim which is not visible after a tire is installed.
A spoke nipple driver would be my preferred tool for that on standard spoke nipples. The end of the driver is registered in the hole in the nipple and it also disengages when the spoke end gets to the bottom of the slot – you could file the end of the bit in your drill to have a similar profile.
I have to agree with that, although “brakes” comes close. I love doing Muni and I have always done it on my 29"/150mm without brakes. Then I got my 36er and after riding happily along for a cople of months on 127s I ended up experimenting with 100mm and even 89mm cranks on it. I also got myself 110/130mm cranks for my 29er, but only rode it around town.
What really blew my mind was trying Muni again after a couple of months of not doing it at all. Everything was so much easier and I tacled obstacles so much more fluently than before, even on 110s (although they have their obvious limits).
On really short cranks, you have to ride more “correctly” and use your upper body more than your legs for balancing and adjustments. And surely it is excellent for training your core muscles. Now I was just riding through the woods and and it was just so much easier than before. I just kept laughing, because it was so unexpected and ridiculous. I was even riding on my street tire! All the rocks, roots and sudden turns were so easy in comparison to tackling curbs, sharp turns and potholes on 36/89mm. Edit: This is actually very similar to this account
Soon after I got brakes on my Muni as well, and those gave me the confidence to tackle steeper downhill sections as well. I still remember the first time going down an impossibly steep and rather long path. I wouln’t even think about going down that on two wheels, but on my Muni I could just cruise down on my brakes, using my upper body for side to side corrections. It is one of the most fun and thrilling things I can remember to tacke that on first attempt.
I made my own symmetrical layout so that one handle protects the brake lever. I keep it somewhat loose so It’ll move on Impact.
The core of these handles are weak aluminum and so they bend easily on big Impacts. I bend them straight again, but eventually the plastic cracks and I have to replace them.
I’d also recommend using the saddle reinforcing plate with this saddle. I’ve broken one without it, but none since using it.
Get some shoes you like and try not to use only 1 kind of shoe. Especially in flatland. The shoes in specific tricks can really change how difficult or easy it will be. Owning DC skate shoes for 2 years did hold me back a bit. They just didn’t absorb the foot impact well, along with chipped shoe sole bits everywhere during practice. I own walmart EVA tennis shoes and they have helped a lot with getting past that plateau. they are cheaper to replace and the friction is more predictable, side padding does not rub up on the forks like my last shoes did.
To be honest I have only had 2 pairs of shoes in my 10 years of unicycling. Most important for me is that they have flat soles and arent too wide. My munipedals have metal pins that bite into the shoes. On the 20” and UW though, my feet may slide off the pedals when it is wet
Biggest one for me was shorter cranks. My first act of “personalizing” my unicycle was changing cranks More specifically, my first unicycle (26" Club unicycle from UDC) came with 150mm cranks, which were the cranks I learned on and rode for about a year. Then I bought 125mm cranks and rode those for a while, and when I put the 150s back on I wondered how I ever got around on those I think now I have 100mm cranks on it, which feels like a happy spot between “a little too clunky” and “my legs will buckle when I slow down”.
A close second for me is having a brake. Especially on a 36er paired with short cranks it makes the riding experience so much more comfortable.
