Neutrino Frameset

 

Sold Out

 

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.

  • 4130 double butted chromoly frame and fork that accepts fenders and rack
  • Unicrown fork with accommodations for fenders, Randonneur Rack, and even a Mojave Cage or a bikepacking-style cage
  • Seattube, downtube, and under-downtube bottle cage mounts
  • 406 Bead Seat Diameter wheel size. That's BMX, so high-quality rims and tires are cheap, plentiful, and strong.
  • Clearance for 2.3" tires WITH fenders. Holy cow!
  • Sliding, 135mm QR dropouts for geared, single speed, or internally geared hubs
  • Disc brake mounts (POST rear, IS front). We suggest 160mm rotors. 
  • Full length, external cable routing
  • 1 1/8" threadless steerer
  • 68 mm wide BB shell, English threaded
  • 31.6mm seatpost
  • Compatible with internal dropper posts. If you aren't using a dropper, you can use the internal downtube routing for the rear brake
  • Paint is Pistachio with reflective VeloOrange downtube decal
  • Click for FAQs and Travel Tips
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.

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

Cheeky little bike, gets tons of compliments from strangers

I bought this bike (custom build) last year. Was lucky enough to grab one of the last 3 available in stock. Super happy with the bike and it really is a do-it-all beast. I lived in Dublin previously and it handled rain, off-road, road and everything in between with ease. Couldn't be happier to be honest and the thing is built solid, so dont feel too precious about challenging it. Also, this thing handles almost like a regular sized bike, I only realise I'm on a tiny bike when accelerating from stop lights. With a front load it rides a lot more stable too, giving it a lower centre of gravity.

All I can say is if you have the funds and the desire to bring one of these little puppies into your life then don't hesitate and just go for it! You will get tons of compliments from complete strangers. I found this especially true. More exciting was when I took it to two different bike shops and they recognised this new breed. Brick Lane Bikes were like "guys, come here, no waaayyyy, a Neutrino!!", as if they were witnessing a unicorn. It's gained quite the cult following, and no wonder really, it's a fun bike that has earned its reputation. Great little mini velo destined to put a smile on your face and those around you.

Tiny bikepacking rig.

I'm already a fan of small wheeled bikes, and I've been bikepacking on my Brompton in the past. After a while, I realised I was just delaying the inevitable - building a Neutrino rather than trying to make my other bikes more like it.

As a short person (5'2) and keen bikepacker, I like how easy it is to pick up a minivelo compared to a larger bike when navigating tough terrain, and I can run full-size carradice bags on this bike because there are no clearance issues. My neutrino has a rohloff because I intend to ride it a lot, up mountains, and it hasn't disappointed me yet. Hopefully one day my bike will be one of the most well travelled neutrino's out there.

The geometry handles well, my only complaint is that the reach is a little further than I'd like, but this was easily solved with Soma osprey handlebars (and it is a fairly common issue on smallest size bikes).

Bike born of gravel meets bmx, raised by a bike messenger.

I recently finished my Neutrino build I describe it as the love child of a gravel bike and a bmx bike raised by a bike messenger. 2.3 tubeless tires, a funky sunrace 9-36 cassette with downhill shimano 10 speed Zee derailleur coaxed into 11 speed service. Cigne stem, bull horn bars,

I don't know what is more fun, the ride or the reaction from people. I can't wait to practice getting this into a bag for train travel. NJ Transit is infamously bike-unfriendly. Initially I balked at discs, but this little guy stops on the dime. No problem with a MTB single crankset with the chainring spaced in 4 mm for a perfect chainline while having no heelstrike issues. I can easily pedal above 25 mph, while still having a low gear for the steepest hills.

Stupid Fun Bike

What a fun little bike. Blindfolded, I wouldn't know I was a mini velo as the geometry is that of a full sized bike. You only notice its smaller when making a turn. Draws gawkers where ever I ride. Built it up with a combination of parts bins left overs, Blue Lug cranks (VO was sold out), Paul levers, Nitto/Fairweather bullmoose bars (also from Blue Lug since VO was sold out) and some eBay wheels. My wife took one spin on MY bike and thanked me for HER new bike. My son steals it for the super fun wheelies. I've taken it out on a mixed gravel/road/beer crawl so far and was surprised at how plush the rear end was. May be a combination of the 2.3 tires and tall carbon seatpost. Looking forward to doing a little bikepacking soon.
