I was hoping for it to be around under 70 dollars? And easy for a beginner.
A bit higher than your stated price but the club 20" would be a great beginner unicycle. It is a collection of good and OKish parts. No major flaws but ask them to swap out the cranks for some 125s (more control for learning).
The other budget uni that is not completely horrible is the Torker CX 20" It is heavier that the club, has oddball parts (48 spoke wheel) a really crappy seat (good seats are expensive, so upgrading the seat would cost a pretty penny) a steel rim and a 22.2mm seatpost (really easy to bend). Nothing super fatal but lots of negatives for a savings of $4
Pretty much anything under $100 will have some sort of fatal flaw. If you find a deal post about it and there are a lot of knowledgeable people on here who will tell you if it is good or not. Probably the best way to get a decent unicycle for under $70 is through craigslist or similar.
Yeah, buy used
For under 100 $ish, any used splined uni is good. For new square hubs, the Torker lx stands out. The club is sorta new, but the lx has been around for years, so you may find some used for 50 $ish. Happy shopping !
I don’t know if these are any good but UDC has a sale for Christmas on this…http://www.unicycle.com/unicycles/trainer-20-inch-blue-unicycle.html
