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:
  • Frameset material: 4130 double butted chromoly frame and fork that accepts fenders.

  • Wheel Size: 20", 406 Bead Seat Diameter. That's BMX, so high-quality rims and tires are cheap, plentiful, and strong.

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.

Beautiful frame, finish is immaculate!

I'm still waiting for the final parts to arrive, but even if I had them I haven't had time to build this yet. I am really looking forward to riding!

Dad bike project, or quiver killer

What started as an experimental dad bike project has quickly become my favorite bike in my stable. The Neutrino medium size frame is rigid where it matters, and flexy where you need it to be. The build comes in at 27.5 lbs the way it is setup in the photo below with the extra bits and beefy 2.4” tires. Of note, I mated the sensah pro shifters to a sram rival rd on an 11-32 11-speed cassette with a wolftooth 38t chainring (what, I’m Towing 100lbs), trp hy/rd brakes, 48cm daija far bars held by a Cigne stem with a wolftooth headset. Regarding tires, the rear does not fit anything beyond 2.4” but the front could take a 3” if you can find one. Keep in mind the velocity rims recommend no wider than 2.4”. P.s., my daughter picked out the purple bits.

Mini Vélo, Maximum Awesome!!!

Took a bit, but finally got this set up just right. The Microshift Advent Super Short hit the market just in time to make it on the build. Perfect match! The VO wheels, Big Ben tires, and Soma Sparrow bars complete the package. It is so much fun to ride.

Great little bike.

If you’re looking for this bike to perform like a 700c or 650b ummm… I can feel less rollover and range. I took it up a 20+ grade and the front wants to lift.

Surprisingly it’s the heaviest bike I own, maybe due to the dropper post, Redshift ShockStop stem and the in cut steer post.

I’m 5’10” with a 29” inseam if that helps anybody building one up. I would relegate the bike to commuter with gravel capabilities in other words a “GREAT BUMBLER!”. A bicycle to take your time with a bike you take out with friends that don’t ride as often as myself.

I like the fact this bike is not intimidating when you ride city trails with pedestrians.

I would describe owning this bike as a celebration of life, maybe a guilty pleasure.

Just built up my new Neutrino. Looking forward to putting some miles on it 😁 Total weight as pictured is only 10,5 kilos, feels really nippy! That Nitto front rack is a perfect little rear rack for the Neutrino.
