What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

A broken connection is a broken system...

Like a lot of good ideas, Dyna-Snap magnetic connectors were born of necessity. As a builder of custom touring and utility bikes, Littleford Bicycles was known for thoughtful integration of useful features. The two most popular perks? A versatile dynamo powered front and rear lighting system, and S&S frame couplings for ultimate portability. (S&S coupled bicycles break down to fit inside a suitcase that airlines consider standard luggage.)   

The trouble was, electrical wiring and frame separation didn't play so well together. For some of my customers, the tiny friction-reliant spade connectors in their wiring would seize, or come loose, or fatigue and break after just a few trips.

Enter the Dyna-Snap!

Dyna-Snaps' first installation was on a Littleford Expedition, a rugged, packable touring bike built for hardship. Thanks to magnetic connections in four places along the frame, the wiring between each segment simply snaps together, and the complete bike, with racks, lights and fenders, breaks down and packs into its airline-approved S&S suitcase.

How do they work?

Dyna-Snaps use smart design and powerful rare earth magnets to make low voltage wire connection reliable, fast and easy.

Traditional mini-spade and bullet connectors rely on frictional contact surfaces to make an electrical connection, but their small size makes them difficult to open and close, and the flat surfaces bend easily-  leading to fatigue and eventual breakage.

Dyna-Snap connectors feature a broad, flat mating surface that holds together without binding, yet is easily separated by hand.

Where are Dyna-Snaps used?

Anywhere an effortless and reliable low voltage wire connection is required. Common bicycle-related applications are shown below because that is the world where Dyna-Snaps emerged- but potential uses abound.

(If you have another application that's perfect for Dyna-Snaps, let us know! We'd love to hear about it!)

 Where's the value in Dyna-Snaps?

Sure, mini-spade connectors are a lot cheaper- they sometimes come free with a dynamo headlight. Here's why Dyna-Snaps are well worth the upgrade:

  • No more fumbling or futzing
  • Automatic connection
  • Ultimate versatility
  • Unmatched durability
  • Quick and easy installation
  • Proudly made in the USA

Why futz? Dynamo lighting is an investment worth doing right.

Dynamo lighting systems are costly. A basic battery powered head and tail light costs a tiny fraction of what a front and rear dynamo system does, yet serious riders are happy to pony up because they want a permanent lighting solution that they don't have to futz with. The same logic holds for magnetic wire connection. Friction-based wire connectors are the weak link in even the best lighting system. With Dyna-Snap, they don't have to be. 

Dyna-Snaps couple automatically and pull easily apart.

Dyna-Snaps couple themselves as soon as they are within reach of each other, so you'll never have to fumble with tiny, stubborn connections in tight places again (like behind a fender, within a fork crown or between the fork blade and hub).

What's more, their ease of connection and natural polarity make complex wiring arrangements a no-brainer; literally AUTOMATIC. By using available reverse polarity connectors, and by installing similarly poled connectors in opposite directions, up to four wires can be coupled and re-coupled without question of what wire goes where.

 Magnetic connection means ultimate versatility. (Free at last!)

Wire connection that is effortless and infinitely repeatable opens up a world of potential. Want to swap a headlight for a GPS? No problem- connecting either device to the same set of wires is a snap. Want the option of both? Split the output wires into four connectors and plug in one, the other, or both. Even four wires (like those going into and coming out of the headlight) can be coupled automatically in one go.

 Magnetic connection is durable and dependable.

Dyna-Snaps are not friction-dependent, so they'll never bind together or come loose. Even more expensive cage-shaped bullet connectors lose their "spring" over time and loosen, eventually to the point of needing replacement.

Installation is a snap.

Dyna-Snaps are easier to install than friction connectors. Because the connector bodies are already insulated, there is no guesswork in heat shrink placement at the contact points. Just slide the shrink up to the base of the connector body and heat for a perfect connection every time.

 Dyna-Snaps are made in America!

Yes, by supporting this project you are procuring a revolutionary solution to a persistent problem in low voltage wiring. But you are also supporting innovation and creating living-wage jobs in America - because Dyna-Snaps are proudly made in Oregon, USA.

How long until Dyna-Snaps hit the market?

Dyna-Snaps have been fabricated in house and installed on custom Littleford touring bikes for over a year, and are already available for purchase at select shops, but production is still small-scale. Having evolved from five-at-a-time hand construction in a custom bicycle shop to a 10 step full production run, Dyna-Snaps have already come a long way. The next step forward: significant investment in production capacity and product marketing to bring magnetic connection to the pedaling masses. That's where you come in!

How about those rewards?

Risks and challenges

Because Dyna-Snaps have been produced and refined for over a year on dynamo equipped bikes, the many product design and performance challenges have been met.

Two major challenges remain, however, and they can both be addressed with adequate funding.

-Branding and product marketing: The problems with dynamo wire connection are real. People need to know there's a solution!

-Production streamlining: The answer to sustainable domestic manufacturing is high production efficiency at living wages, not criminally cheap labor overseas.
