Adler concept


The Adler will be a fully enclosed pedal powered tricycle with an electrical assist motor. Because the Adler will be legally a bicycle, no license or insurance will be required to operate. It’ll travel on bike paths, park on sidewalks. It’ll require no gas, license, registration or insurance.


Electric speed: 20 mph

Speed limits for power assisted bikes are often set by the individual states. In general, most states require that that the maximum speed not exceed 20 mph. For this reason, as well as safety we recommend that you do not exceed the local limits and in no event exceed 20 mph.

Electric range: 30+miles

The Adler could be used totally in electric mode without pedaling. Mileage will vary depending on terrain, person’s weight, and temperature.

Assist range: 40+ miles

You also can pedal with “electric assist”, which means that as the same time you pedal you twist the throttle of the electric motor to aid your pedaling. Pedaling will increase the range of your battery package.

Electric motor:

It’ll have a 750 watts, which will be big enough to get you up and down hills and where you need to go with little or no sweat.

Use as a bicycle only

It’ll possible to use the Adler as a regular bicycle, but the Adler is being designed to be electrically assisted.

  1. Dear,

    I am interested in buying an Adler tricycle. I would lime to know how much it costs.
    Is it possible to ship to brazil?

    Thank you


    • Dear Marcos,
      We are still in the prototype stage. We are testing the new frame for the Adler. We will, in the future, modify the entry. We want to place a door, just like a regular car. Because of all these changes, we are not ready for production.
      The estimate cost is 3,900.00 US dollars. Once in production, we could ship it anywhere around the world but cost of shipping and import taxes will be paid by the costumer.
      Thank you for your interest in the Adler,
      Eliel Rojas


  2. I am seeking an ADLER like vehicle with the following characteristics
    Tandem seating for 2
    Cargo room for 3 or so bags of groceries
    Potential for solar charging while at work
    Expansion room for optional additional battery pack
    Curt Brasier


    • Curt,
      I’m sorry to tell you that the Adler has no possibility to become a tandem. The other possibilities for cargo, solar charge and battery pack expansion can be customized. We are not in production yet.
      Thank you for your interest in Enclosed Bikes,


  3. I am interested in a bike like the Adler. Can you tell me what the external dimensions of the bike will be? I have been looking at other enclosed ebikes like the ELF and most seem to be too wide to easily fit in bike lanes and bike paths. Do you have an estimate of when it will be available?


    • Natalie, the dimensions are 92” long x 36” wide x 56” tall. the width is 36″ but we are working in making it smaller. We are testing different suspensions that can make the vehicle stable and narrow. The goal is to be in production by the summer 2018.
      Thank you for your interest in enclosed bikes,
      Eliel Rojas


    • Yes, it will be fully enclosed. Heating options are available, but producing heat consumes too much energy. So, for an electric bicycle the batteries would need to be too big. So far a simple option is not feasible. Options for those to whom heating is a most, options could be discussed once the Adler is on production.


  4. Looks like a great option! Will the Adler have turn signals and/or a windshield wiper? My commute is 19 km on 2-lane country n suburban roads. Ontario Canada limits engine to 500 kw. Thank you


    • Kit, Yes, it will have turn signals, no windshield wiper. The electric motor will be 500kw. Originally it was planned for 750Kw, I’ll update the info. The goal is summer 2018 to start production.
