The Stroke Cargo Trike is Daga’s new mobility solution for Japan. It fits Japan’s legal definition of an electric-assisted bicycle, making ownership and use as easy as possible, and like other products designed with Japan in mind, the thinking necessary to make a product work in the world’s most demanding market makes the Stroke Cargo Trike special anywhere:

STROKE Cargo TrikeはDagaの日本における新しいモビリティの解決策です。誰でも簡単に乗れるように厳しい日本国内の自転車法規を満たし、結果的に他の国でも楽に使えるカーゴバイクを目指しています。

Compact: At only 1.9m long with a tread of less than 50cm, the Cargo Trike has a minimal footprint and is no wider than the handlebars of a conventional bicycle.


Rideable: Mid-mounted cargo space means that as you load it up, the centre of gravity just gets lower and more central. The tilting front wheels are always visible to the rider and the double steering linkage is direct and light. This thing is fun to ride!


Manoeuvrable: With a short wheelbase and ample steering angle, the Stroke Cargo Trike is easy to turn at low speed and steers smoothly into regular bicycle parking spaces.


Adaptable: The surround frame, design-registered in Japan, will be developed with custom attachment points for maximum luggage flexibility. Boxes, bags, custom-built cases – bolt them on, strap them down or suspend them, it is up to the user.

高い汎用性: 意匠登録出願中の特徴的なフレームは、各種アタッチメントにより大きな荷物の取り付けも可能です。ボックス、カバン、特別に作られたケースなどをボルトやストラップで留めたり、と使い方はユーザー次第です。

What you see here is the latest proof-of-concept prototype, the Daga concept frame and steering system adapted to use proprietary running gear. Road tests have proved that it is easy and fun to ride on flat terrain and steep hills. Now we are looking for partners to help us take the Cargo Trike to the next stage – final design prototypes and into production.

Daga project is moving forward and we have just announced our biggest product so far. It is more than a twinkle in our eyes, but still needs a lot of sweat and probably tears to turn it into a real product. I am hoping to avoid blood.


Daga STROKE Work-Trike

It is a tricycle: not one with a big wheel at the front (and fixed pedals that bash you in the ankles when you go too fast down a hill) but an electrically-assisted cargo mover. A “mobility proposal”.


Daga STROKE Hot Food Trike 

Why a mobility project? And why a cargo mover?


Daga STROKE Delivery Trike 

Japan is probably moving away from an automobile centered society faster than any other developed country, even while building new roads hell for leather. Public transport is excellent and relatively inexpensive, urban roads are crowded and the idea of a car as a status object is becoming confined to smaller and smaller circles of people. Practicality rules, so that whereas almost everywhere in the developed world has fallen under the spell of SUVs, in Japan the minivan is King, especially in the guise of almost cube shaped kei-cars.

The environment for bicycles is not great but they are faster than anything else in the narrow streets and in towns the whole place swarms with them, especially electrically-assisted ones for getting up the ubiquitous hills.



Another type of vehicle you will find in swarms is courier trucks. Courier delivery has a long history, is highly developed and specialized, and internet shopping has boosted it to new heights. Not to mention the very efficient postal service or hot food delivery, usually swinging around from the back of a Honda Cub or pizzas in the hot box of a covered scooter.


This combination of a practical approach to transport, narrow streets, limited parking and a highly developed delivery environment makes urban Japan ripe for a vehicle that can carry more than a bicycle or scooter, get around narrow streets quicker than a truck or van and cost peanuts to run.


The problem – and a home-made solution. 

The Daga mobility vehicle is designed to fit into Japan’s bicycle category, so no driving license is necessary. (It would be helpful if the government would tweak the law and take away the ridiculously low speed limit (24km/h) and the requirement that a bicycle cannot run on electric power only, but we are not the only people who think so and we hope that the law will change soon.)



At Wonder Festival Summer 2016. 

So far we have only made small scale “concept models” and you are probably looking at these photos and thinking, “So, what’s with the dolls with ridiculous proportions and skimpy shorts?” Well, we decided that we would announce the project at the Tokyo Wonder Festival. At the moment the trike is only a proposal, our fantasy of a parallel world in which a new kind of mobility is available, so we thought that some of the people most likely to imagine along with us are the people who spend their days imagining different worlds in the form of manga and anime. We proposed the tricycles in three scenarios, a “work trike” for factory floors, warehouses and construction sites, a “hot food service trike” for delivery tasty bowls of noodles to your door and a “courier bike”, no explanation necessary.



“work trike”工場、倉庫や工事現場で活躍するガテン系作業バイク。
“hot food service trike”は街の中華屋のお気軽出前バイク。
“courier bike”は次世代の最速宅配バイクです。

At Wonder Festival 

Wonder Festival is the place to see figurines, of anime and other fantasy characters, made to really wonderful levels of detail and expression. With the help of a figurine designer, Atomic Bom, who specializes in bike girls, we could attract the attention of attendees of the festival and complete the scenarios we want to create with a human presence. Well, sort of human.



We also made a 1/3 scale model, an unpainted 3D print in sintered nylon powder.

And if you are wondering what the STROKE thing is, the cargo trike is just the first of a series of Daga products to be based on pipe construction. The pipes will bend and join to “write” the products, like the strokes of calligraphy.

We can design and give them shape but to take them to the next step we need supporters and partners. Wonder Festival was the first step in building a fan base for our cargo trike – now we are looking for the people and companies who can help us get it onto the street, soon.

カーゴバイクの存在は 数年前から知っていて、最近日本でもごくまれに遭遇することもあり何度か乗る機会もあったが、慣れるまでとにかく乗りにくい!(とりあえず長すぎる、大きすぎる)

日本の自転車にも当然法規があって、サイズ( 普通自転車 )が決められてるんですよ。これが結構ネック。このサイズに収まらないと軽車両扱い(そもそも自転車も軽車両に含まれるが、道路運送車両法 と 道路交通法 では解釈?が違う)
とても複雑な内容なのでここでは省略しますが、要するに「普通に自転車として乗るなら、 普通自転車の規格に合わせてね」ということ。なので海外製のカーゴバイクやリヤカー系の自転車などは、普通自転車のサイズから大幅にオーバーしてるので、厳密に言うと自転車じゃないんです。




名前もSTROKE Cargo Trikeです。
