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.

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.

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.

Fun and Functional

Suuuppeerrr fun bike, and totally capable of hitting the trails. Not twitchy at all, and surprisingly plush. Only time will tell how it does with the dropouts slammed back. Probably the cleanest BB threading I've received on a frame. Finish is a 4.5/5. Internal routing for a dropper was an A+ addition. XXL fits naturally for this lanky 6'2" person.

Parts are scarce to build what you want. I am a week or two away from starting the build. Bob

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.
