The pen size is measured by the diameter. There is a BIG difference in terms of area of the balls used in the pens. A .7mm tip refers to a .35mm radius and a 1.6mm tip refers to a .8mm radius. Using just regular geometry the area of the gel pen tip is only 19% that of the ballpoint. Ballpoints have to be large because you are not actually using the entire diameter of the ball, but rather a smaller diameter closer to the "pole" of the ball(which is what I call the part of the ball that makes contact with the paper). Gel pens tend to use much more of their diameter tips when writing so they don't have to use as large of a ball tip.
What a coincidence that you uploaded this when you did. I’ve spent the past week looking for Gelocity reviews, and was surprised at how little I was able to find (especially recent ones). Thanks as always for the thorough reviews! That dark blue in the Velocity looks great btw 👍🏽
5:41 - I don't know if it's an optical illusion or it's just me.. It seems like *Diffuser* mechanism just below the nib inside the refill of the Gelocity ? 😲 Simply put, a *Nozzle* is used to increase the *Speed* of the fluid and on the contrary, *Diffuser* is used to increase the *Pressure* of the fluid passing through. From Engineering perspective, it's piquing my curiosity 😅
Two of my absolute favorites! I have the whole series of both. I'm gonna go with Velocity, but any of the Atlantis line are great, I use them all the time!
Actually, the gel-ocity will not take a G2 refill. The stock catridges are slightly thinner than a conventional G2. Although, I think it holds the same amount of ink as a G2. My guess was they made the refill thinner to cut costs.
I cannot think of a real reason to prefer Energel over the Gelocity. Both are equally smooth and vibrant, neither are really waterproof and the Gelocity is half the price, yet for some reason I still find myself gravitating to the Energel over the Gelocity
The velocity is my favorite pen to use for school for nonstop class notes. As a lefty, it does smear on my pinky, but it writes so smoothly I can't give it up. I didn't use to like big ballpoint pens but I really like this one. And I'm too picky when it comes to pens (the wrong size or grip makes my handwriting messier) so it's still the only pen I use since I first tried it 2 years ago. Gonna watch more of your vids to see what pens I'm missing out on!
I must try it. I'm a big fan of fountain pens but it's not comfortable for my work, so Gel pen is my second choice. I've used Energel before but I don't like its colour. I hope Gelocity would be better.
I adore bic gelo city. I have a couple of faber castell rollers, so I buy the big gelo city and I use the refills cos they are so cheap. But I also have a bic gelo cities that I keep in my bag, as a spare.
If the gel refill for the Gelocity is the same as the refill for a Bic "for Her" I have here, that refill fits in both the Pilot g2 I have and my Energel Alloy. Strangely, I dug out a different "for her" gel pen I have and the refill for that one seems to be a tiny bit shorter than the one in the other pen and doesn't fit ANY of the pens properly, including the one it came with. It doesn't come out quite as far as it should. It still works but it looks weird. I've never used that pen so I'd never noticed before. Odd.
I still have 8 double packs of Bic Velocity 1.6 size black. The office depot had them as a back to school special at 50 cents each pack around 6 years ago. I don't even know if they are still good, and don't ask me why I bought them. I never opened up not even one package.
@@unsharpen ........Honestly, I bought them because of the price. I never intended to use them. I'm a Fisher space pen fine point blue user. Maybe some year I will give them away to the convelasant home where I volunteer during the holidays.
Since we are talking Bic, can you review the Bic Cristal Re New? It's not available in the U.S. It's made of aluminum and is refiillable. I bought one for my collection.
I gave in a while ago and purchased both sets. I hate both which is amazing, I've never really hated a gel pen before this one, the other was also underwhelming as well.
@Voltaic Fire I'm a lefty but learned to write with my right hand early on, on my mother's recommendation especially because of the smudging issue. Where I grew up, kids had to write with fountain pens at school, so it was probably a good thing. Once I was allowed ballpoint pens when I went to high school in California for a year, I really got to like ballpoint pens. Now as an adult, I do prefer ballpoints. It's just a smoother experience for me.
@@unsharpen don't listen to this kind of guys bro, this is a pen channel not a calligraphy one, you review pens for everyday users, obviously not all of us have a perfect handwriting, but we want to know which kind of pen better fits our needs. Thanks for you content bro
Bic is the best they got us all started .

Thanks for the thoughtful comment Tony. That makes a lot of sense!
Yeah I’ve found that as well. If you look, a .7mm gel pen usually makes the same line a 1 mm ballpoint would.

Recently discovered your channel, and I can't stop watching your videos! Keep up the good work!

Gelocity wins. No contest.
The Gelocity is turning into my favorite pen.
Very easy to hold and write with….

I was able to shorten the refill from a velocity pen and installed it in a Zebra 701. It made for a nice smooth writing pen.
Interesting.... I'll have to try that.

Hello, I am not sure if there are the same, I found the Blue and white pen at the 99cent store
If the gel refill for the Gelocity is the same as the refill for a Bic "for Her" I have here, that refill fits in both the Pilot g2 I have and my Energel Alloy.

Are there Re- Fills for the Bic Gelosity pens?
I still have 8 double packs of Bic Velocity 1.6 size black. The office depot had them as a back to school special at 50 cents each pack around 6 years ago. I don't even know if they are still good, and don't ask me why I bought them. I never opened up not even one package.
6 years? Should be fine!

G- 2 cartridge will not work in the bic Gel osity pen.
I love the Bic Gelo-city pen ....There is no Scratching feeling with this pen..

Hm let me check into that. Thanks
Is montex paper point a gel pen? Need a fast answer cause I used this in exams?
The Velocity seems to write as smoothly as the Korean Profile ballpoint pens.
What's the thickest line most common blue pen that you can find?
1.6mm bic
@@unsharpen thank you, I'll take a look!
I second that-- It really is nice and thick. I would love to see a 1.8 mm LOL!!!😁
What about the Bic ReAction Gel?
I think this one is out of production. I’ve not tried it in years
I gave in a while ago and purchased both sets. I hate both which is amazing, I've never really hated a gel pen before this one, the other was also underwhelming as well.
What were the reasons you hated it? I just wanted to know since I was planning to order both. Thanks.
Hey Sal
Could you recommend me an absorbent paper for left handers, (I don't mind a little bit of feathering) for college. Thank you.
I’m very into the silvine lately. If you can’t find that then try midori cotton.

Gelocity is the worst gel pen I have ever used, the ink takes forever to dry and as a left it just smudges too much.
Idk what the heck im doing here.
36 for under $10 Amazon Warehouse
The irony that it’s a pen specific channel and he has the absolute worst handwriting ever
What's one have to do with the other? Do only professionals play sports?
