Yooniq 20-inch wheel bicycle

[spinningmagnets]

I have seen several "Cannondale Hooligan" builds, and I recall a similar frame that was slightly more appropriate for attaching a battery pack to the "triangle" portion of the frame. The Yooniq bicycle is from Slovakia. Aluminum, 20-inch wheels (which allows a wide variety of tires). It also has the option of an eccentric bottom bracket (an eccentric allows a bike to have an IGH or single-speed with no chain tensioner, also a belt-drive instead of chain with no tensioner).

I like it for a "grab and throw" bike which can be put in a car trunk or the back of a van easily, or carried up and down stairs. I would add QD nuts onto the front axle. the combination of QD axle-nuts and a disc brake means that the front wheel can be removed and re-attached very fast and quite easily with no tools.



Luna Cycle just built up a Cannondale Hooligan with a BBS02, and then immediately upgraded to a BBSHD, but...even though they were able to squeeze a shark pack onto the frame, the Yooniq could easily accept a larger dolphin pack, yes?

That's a nice looking frame that could accommodate a pretty sizeable battery..
My problem with it is the lack of front suspension though, and the fork angle is rather extreme already, that if you added a suspension fork to it, it would be a problem.

Riding a 26 inch wheeled bike with no suspension at high speeds is already hell on the bones. 20" is more hell on top of that.

looks like a fun bike. the lack of rear gears would make me pass on a BBSHD in favor of a hub motor. Something like that might be fun with a Q100H. While an off the shelf battery would make a clean conversion, i think a custom made cloth frame bag that fit that open space for the battery, and included general storage as well, would make that a useful little urban scoot.

What's the price on those?

Might as well get rid of that seat. The only time in my life that I was comfortable on 20" wheels was on the pedals.

Here's a UK review comparing the Hooligan to the Yooniq, both with 3-speed IGHs

https://www.bikesoup.com/magazine/yooniq-bike-tough-agile-urban-commuter-bike-review/

The Hooligan is priced at £799 & the Yooniq is priced at £690

At this weeks exchange rate to US dollars: Hooligan $1150...Yooniq $1000

If you're looking for a mini-velo and haven't seen it, check out http://respectcycles.com/p/bike .. horizontal drops would take an IGH easily.. you could install a disk fork if you wanted the braking power.. and it's a chromoly frame .. at sub $400 you'd have room to play .. also, unless the Yooniq has a split in the rear triangle, you won't be running a belt..

Very nice, that could take any of the popular battery packs...shark, dolphin, or large triangle.

Also recently found the turn-key ebike "Winora Radius Speed", very similar to the Yooniq.

FYI on the Respekt Bicycle:

1) 130mm rear dropout spacing. Not sure how wide a tire it fits, but I've seen one in person, and I'm guessing 2" wide max.
2) "BMX" style bottom bracket, won't accept a BBS system because the BBS diameter is smaller than the bottom bracket diameter. Is there an adaptor available to make this a moot point . If there is an adaptor, is it up to par to withstand the torqueing forces down there .


At 20" wheel maximum, I go into the camp of make it a rear wheel drive, single-3speed hubbie. I've seen BMX wheels up to 2.4" width; would a Yooniq (or a Hooligan) accommodate them?

A few here might remember the "Machine X", which used the "Burro bike" frame.

How about the Origin8 Bully, now out of production:

Interesting how much battery space is created by the small front wheel.

Hmm, looks like good frame ideas to copy next winter when I'm bored.

Loving my Hooligan, the front and rear disks sold it for me. Plus I picked it up second hand but like new for 600AUD.

Bbs02 is a great fit, only improvement I could see would be an Astro build like one of the tangent drives, but the speed would be overkill.

Still fine tuning it but so far it's my favourite bike I've built.

Bikes direct is again selling a mini velo, Mercier Nano, CrMo frame, 130mm rear spacing. Saw it at my LBS and the BB (looks like 68mm or 73mm) should accept a BBS middie. The guy who owns it had put a 60 tooth front chain gear (non motorized). I'd put a BBS on and swap out the rear wheel to a 3speed IGH. :wink:

Read the link, and a forum member talks about a mini velo called Java Mini (looks like aluminum). Better components vs. Nano, FWIW. Getting this bike to ship outside the Asian market could be costly.
