Whether you're a frequent traveler, apartment dweller, multi-modal commuter, or just enjoy a fun N+1 bike, the Neutrino will fit perfectly into your heart.

For city and apartment dwellers, you'll get great acceleration for stoplight racing as the wheels spin up quite fast. When you've reached your destination, getting the bike into the building, walking up stairs, and parking it in your apartment is so much easier because the physical length of the bike is greatly reduced. You can much more nimbly negotiate stairwells and since it's warm and cozy inside, you don't have to worry about it getting ripped off overnight.

For multi-modal traveling, it's easier to take the bike in a train car without taking up a ton of room and attracting disdainful looks from fellow commuters. Oh and Rinko. Forget cutting fenders, removing handlebars, and wheels. Just loosen the stem, turn the handlebars 90 degrees, and put the whole thing into a Rinko bag!

Traveling with the Neutrino is also a breeze. Since we often travel to our cycling starting point by airplane, train, car, or bus, overage fees for checked bags, storage, and transportation add up quickly and are a real drag. To take full advantage of the traveling abilities of the Neutrino, the bike can be disassembled and inserted into the cardboard box that it comes with.

Simply put, the Neutrino is a blast to ride around. It'll put a smile on your face every time you throw your leg over.

Here are the specs:

We carefully tweaked the geometry to obtain a completely normal riding bike without any drama. Since the sizing is a bit less-than-traditional, we generally suggest folks that are 5'6" (168cm) and under go with a Small, and folks between 5'6" and 6' (183cm) go with a Large. If you're 6'1" to 6'4" (193cm), go with a XX-Large.

Please note: the XXL size is slightly too big to be packed as a regular checked bag like the other sizes.

If you are getting a VO Headset along with your frame, you can get it installed for a reasonable fee. Simply click here to navigate to the installation charge page, and add the fee to your order before checkout.

Neutrino frame

Love the frame, small and cool

So good I lost it and bought another...

So I will start out by saying that I lost the first frame in shipping and didn't get reimbursed by USPS...I bought another one.

TLDR, I accidentally ordered a small frame and sent it back for return. USPS lost it, didn't get refunded, and bought another one because this frame is probably the most fun I've had on a bicycle.

I have a lot of other bikes, I have a couple of e-bikes, and for whatever reason I keep this bike always around to jump on. And that is just it, you just jump on this bike and ride. It's easy to store and it's easily put out of the way.

I ride this bike with my kid all the time. I travel with this bike. I jump on this bike to go a quick loop around the cul-de-sac because it's just that much fun. It also wheelies exceptionally well ...there, that's reason enough.

Flinty & Fun

Could not be happier with this bike. The small wheel/frame combo is unbeatable in urban settings, lower top speed but zippy acceleration. Handles like nothing else out there, and the utility of this bike is impressive making it very easy to live with.

The small size coupled with a dropper make this an easy bike to maneuver in elevators and tight quarters- if you're an apt dweller the form factor will delight you.

Some may label this as a frivolous N+1 bike, but I see a solid option for those looking for something more solid than a folder, but more diminutive than a 26in or 700c city bike.

Only thing aside from top speed that this bike can't do is bomb hills. anything over ~20 mph feels like you're going to shake hands with the grim reaper. But why would you want to go fast on this anyway? This bike invites you to cruise down the street and just enjoy the two wheel feels

Super fun and super cute

First thing I need to mention is how cute the bike is. The paint job is excellent. It bings smiles to people wherever I go.

I built mine up as a single speed with Klunker bar and chubby tires with fenders for city riding. It is so fun to ride and might replace my Brompton in some occasions.

Also tried loading it up with a bar bag in the front and panniers in the back. The ride becomes more stable with front load heavier than the rear. Will convert it to internal gear hub for touring some time later and I’m sure it will handle everything very well.
