Component Technology

Component

The BioLogic FreeDrive encloses the bicycle chain to keep the rider’s clothing protected from grease and dirty spray. The FreeDrive’s ingenious design moves with the chain so it is friction free, unlike with some other chain protection methods. It also reduces chain vibration and noise.

BioLogic Joule Dynamo Hub

Component

There's nothing we like better than clean energy. A hub dynamo is the most efficient way to generate electricity for your bike light. The hub is embedded with a dynamo that generates electricity while you ride. The Joule hub features a polished aluminum hub shell and is made to our 74 mm compact width specifications. It is one of the lightest and most efficient hub dynamos on the market.

BioLogic Traveller Rack

Component

Just because the bike has smaller wheels doesn’t mean that the load gets smaller. That’s why we went back to the drawing board to redefine what a touring rack for a 20” bicycle can be. The BioLogic™ Traveller Rack fits most full-size panniers, and still leaves enough heel clearance for those blessed with “larger” feet. Lateral stiffness has also been improved and it even features a recessed rear light and handy hand hold for lifting the bike. The Traveller Rack is a must have for any serious touring ride.

Boost Technology

Component

Boost Technology is a powerful electric propulsion system that was designed by Dahon and Japanese engineers over a period of two years. The Boost system adds a “boost” of power with every stroke of the pedals, measuring the amount of force that the rider puts in and then multiplying it. Three custom-tuned power curves or “boost modes” are available. Advanced electronics and lithium ion battery technology make the Boost one of the lightest electric systems on the market. A fully equipped Dahon bicycle with the Boost system weighs as little as 19 kg.

Camlever Quick Release

Component

Quick releases are everywhere: on seatposts, wheel axles, and even on our Telescope handleposts. And don't they make life a lot easier? Some of you may remember when seatposts were fastened with a bolt and nut, and every time you wanted to adjust the saddle height, you had to go rummaging for tools. But we'll bet you didn't know that the present quick release design that combines a nylon platform above a round washer/cup and a cam shaped lever was conceived by our president, 17 years ago.

Compact Front Hub

Component

As a rim gets smaller in size, the bracing angle of the spokes changes. If you lace a standard 100 mm hub into a 20” or 16” rim, you end up with spoke bracing angles that are non-optimal, which results in a weaker wheel. To solve this problem, we pioneered the Compact narrow width front hub: optimized bracing angles result in wheels that are stronger than comparable 26” and 700c wheels.

Dahon Andros Stem

Component

The revolutionary Andros Stem features 2D adjustment, up and down, forwards and backwards, with a single quick-release lever. The single lever simultaneously controls both stem and bar so it takes only seconds to adjust your riding position. Riders of any size, whether they prefer a comfortable upright riding position or an aggressive performance position, will be able to find their preferred position. The Andros features a twin-stem design, making it the stiffest, strongest adjustable stem on the market.

Dahon Axis Stem

Component

With over 120 mm of height adjustment, and over 85 mm of reach adjustment, the revolutionary Dahon Axis stem accommodates riders of just about any size, whether they prefer a comfortable upright riding position or an aggressive performance riding position. But even more exciting is the new stem storage system that lets riders easily rotate the stem 90 degrees and out of the way for storage or transport.

Dahon F.I.T. Stem

Component

Getting just the right handlebar height with a traditional stem/handlebar set-up is a pain. Typically, you can only adjust bar height in 5 mm increments. With the new Dahon F.I.T. stem, you get 50 mm of on-the-fly vertical adjustment, with no increase in weight or complexity.

Dahon Neos 2.0 Derailleur

Component

Traditional rear derailleurs weren’t designed for small wheels: long cages leave little ground clearance and large parallelograms protrude awkwardly from the frame, vulnerable to damage. To solve these problems, we developed the Neos line of derailleurs. The revolutionary low-profile design mounts directly to the chain stay with the body of the derailleur tucked underneath, protected from damage. In recent years, Shimano has seen the logic of such low-profile designs and has begun to incorporate it.
